Executive Summary

Bringing Application Optimized Storage™ Solutions to a Broad Range

of Organizations

Regardless of the size of an organization, Application Optimized Storage™ solutions from Hitachi

Data Systems open new possibilities to better align storage infrastructure with business objectives.

Hitachi TagmaStore® Adaptable Modular Storage and Workgroup Modular Storage models play an

important role in building Application Optimized Storage solutions to match application

requirements—such as performance, availability, functionality, and cost—with storage attributes,

across a wide range of organizations.

Instead of providing different products for different-sized organizations, Hitachi Data Systems

employs the same set of products to focus on a common tiered strategy for aligning storage

characteristics and business application priorities, whether for a large enterprise or a smaller

organization. Application Optimized Storage solutions offer integrated hardware, software, and

services that utilize Hitachi modular storage systems in a tiered-storage architecture, which

maximizes storage investment returns for businesses of any size. It’s only a matter of scale. The

Application Optimized Storage strategy takes the same quality and data-availability standards found

in systems used to power the world’s largest banks and makes them available to midsize businesses.

Small businesses can rest assured that they are using versions of the same hardware, software, and

services the largest enterprises use, and the largest enterprises can be confident that they are using

the most cost-effective solutions to meet their business objectives.

Hitachi Data Systems believes that all organizations deserve enterprise-level functionality—high

availability, high performance, simplified central management, and tiered solutions that align storage

directly with business objectives. Because many organizations have limited budget, staff, and space,

Hitachi Data Systems is offering modular systems that are scaled to fit environments and budgets in

the modular storage market space.

Announced in July 2005, the new Hitachi modular storage systems are an architecturally advanced

offering not only in terms of footprint and performance but also in terms of policy-based

manage-ment software features. These modular choices enable both large enterprises and smaller organizations

to address storage challenges with automated management, affordable and easy-to-grow packaging,

and a proven investment-oriented storage solutions strategy:

All Hitachi modular storage systems can be configured and managed from a “single pane of glass”

with the easy-to-use graphical user interface of the Hitachi Storage Management and HiCommand®

Suite software. Best-of-breed high-performance hardware and cache partitioning set these systems

apart from the competition. The industry’s highest level of data availability is offered by the most

advanced business continuity software, including Hitachi ShadowImage™ In-System Replication and

Hitachi Remote Replication software, available on the larger modular products, helping you keep

management simple while avoiding downtime and data loss.

TagmaStore Adaptable Modular Storage, Models AMS200, AMS500, and AMS1000: the

“Mixable SATA and Fibre Channel” Storage Systems

Adaptable Modular Storage systems can serve as both the first tier (Fibre Channel disks) and second

tier (SATA disks) of storage for a workgroup or midsize company, providing a self-contained “tiered”

solution in a single system. Adaptable Modular Storage systems are intended for consolidated

heterogeneous open systems computing environments and for applications in e-commerce and

Web serving.

Adaptable Modular Storage models offer a variety of features and functions that address the needs

of midsize organizations or the tiered-storage requirements of the enterprise. “Single pane of glass”

management of all Hitachi storage is enabled by Storage Management and HiCommand Suite

software. Each model provides simplified software for quick and easy configuration and

management. They also offer cache partitioning, allowing applications with different-sized data

blocks to be precisely tuned, thereby optimizing their performance.

For connectivity, native NAS and iSCSI support allows IP-based files or volumes to be managed with

the same tools as storage area network (SAN) volumes, thereby reducing management overhead.

Unique in the modular market space, RAID-6 dual parity striping provides greater availability by

protecting against the rare event of a second hard disk drive failure in a RAID array before successful

rebuild of the first failed disk. All Adaptable Modular Storage models offer mixable SATA and Fibre

Channel disk drives to allow workloads to be hosted on the most economical storage, based on

assigned application priorities. Logical Unit Migration enables data to be moved nondisruptively

between tiers. Finally, redundant, hot-swappable components and the Hi-Track® “call-home” service/

remote maintenance tool support maximum uptime.

(4)

TagmaStore Workgroup Modular Storage, Model WMS100: the “All SATA” Storage System

The Workgroup Modular Storage model WMS100 is ideal for midsize companies or workgroups that

require the best in scalability and performance in a small footprint. The WMS100 supports

cost-efficient SATA drives while maintaining the performance and reliability edge that world-class Hitachi

engineering delivers. The WMS100 is perfect for applications lending themselves to modular

workloads, especially where a SATA option is a good fit, such as with:

: :

Smaller Microsoft Exchange operations that seek optimized storage

: :

Enterprise resource planning and customer relationship management systems with small

organization workloads

: :

Database applications with moderate workload characteristics

Like other Hitachi modular storage systems, the WMS100 provides advanced Hitachi cache

partitioning, which uniquely allows administrators to efficiently allocate cache and tailor block size

to specific applications, thereby optimizing their performance. Redundant, hot-swappable

components and remote monitoring through the Hi-Track service/tool are also supported.

The WMS100 can also serve as second- or third-tier storage for the enterprise.

Hitachi Modular Storage Systems

Set New Industry Standards

Hitachi modular storage systems once again move the bar above the reach of the competition and set new standards for modular storage systems in terms of advanced enterprise features not offered by any competitor. These systems lead the market, not only in terms of capacity and performance but also in terms of management software. It is becoming widely accepted by industry analysts today that storage systems must be surrounded by features and services that enable simplification of storage management—even for smaller organizations and entry-level enterprises.

Organizations of All Sizes Face the Same IT Challenges

From the small business to the large enterprise, organizations of all sizes face the same IT challenges. It’s only a matter of degree. As you seek to gain competitive advantage and grow in your respective market, you are facing many of the same data storage challenges and pain points as large enterprises:

: : Data growth continues to accelerate.

: : Older storage devices are unreliable and perform poorly.

: : Hard-to-meet regulatory requirements often apply, regardless of company size.

: : IT budgets and head counts are flat or shrinking.

: : Hard-to-manage storage infrastructure—server-internal disks or server-attached storage

from multiple vendors—drives management cost to several times the acquisition costs.

: : Backup-and-restore windows are shrinking.

: : Disaster recovery time objectives require that applications be recovered within minutes or

hours.

: : Applications are not meeting performance and availability expectations.

: : Compliance requirements and litigation fears demand that data be kept in tamperproof

storage for defined time periods and made available quickly when necessary.

: : “Old” data needs to be online and accessible within a short time (generally seconds or minutes).

The primary difference is in the scale of these issues. Like large enterprises, smaller organizations are faced with managing disparate storage islands tailored to individual server applications such as Microsoft Exchange, Microsoft SQL Server, Linux, and file servers. Growth for an organization of any size means increasing storage infrastructure demands for higher capacity, increased utilization, improved performance, business continuity, and data protection, as well as the need to simplify overall management in an environment of increasing regulation. The Hitachi modular products offer best-in-class scalability and performance and enable shared storage consolidation across platforms by increasing utilization, sharing capacity, and simplifying overall management. From high-end to entry-level, Hitachi modular storage systems meet these challenges.

Hitachi Modular Storage Systems Benefit Smaller

Organizations and the Larger Enterprise

Whatever the storage challenges facing your business and whatever the size of your business, Hitachi Data Systems offers storage solutions that are sure to fit. Hitachi Data Systems product positioning for businesses of various sizes is defined in terms of Application Optimized Storage™ solutions, and does not use a “one size fits all” approach. As shown in Figure 1 and Table 1, Hitachi modular storage systems take on multiple roles—serving in varied storage tiers1_{—depending on the size of the business, installed equipment, Application Optimized}

Storage strategy, and other factors. Because they have the same functionality as Hitachi enterprise systems, the new modular systems fit seamlessly into the proven, enterprise-caliber Application Optimized Storage solutions—aligning IT with business objectives and scaling to fit your environment and budget.

Positioning for the Enterprise

For large enterprise environments, Hitachi modular storage systems complement the Hitachi TagmaStore Universal Storage Platform and Hitachi Lightning 9900™ V Series enterprise storage systems in tiered Application Optimized Storage deployments. As shown in Table 1, the Universal Storage Platform models USP100, USP600, and USP1100 are typically found in enterprise-level (raised floor/data center) installations, where their internal storage is designated as first-tier storage, with externally managed Universal Storage Platform storage as second- and third-tier storage. In this scenario, TagmaStore Adaptable Modular Storage and TagmaStore Workgroup Modular Storage can fill the roles of second- and third-tier enterprise storage. With a minimum number of disks, the TagmaStore Network Storage Controller model NSC55 can function in the entry-level or large enterprise as an “expansion controller” to centrally manage external storage as second-tier or third-tier storage, whether it is Hitachi storage or third-party storage. For the high-end enterprise, therefore, Hitachi modular storage systems with the SATA Intermix Option complement Universal Storage Platform or NSC55 systems in tiered-storage deployments for applications such as:

: : Data lifecycle management

: : Streaming

video

: : Noncritical

Web serving

: : E-mail

archiving

: : Lower-priority decision-support applications such as data warehousing

: : Mainframe volume archiving for compliance

: : Mainframe

tape replacement

: : Other lower-priority applications

A large cost-savings opportunity for the enterprise is to replace a mainframe disk with a SATA disk behind a Network Storage Controller or Universal Storage Platform. This can defer or completely avoid an enterprise disk purchase cycle, depending on how much of the backup mainframe disk can be repurposed.

(11)

Positioning for Midsize Companies and Workgroups

In entry-level enterprises Adaptable Modular Storage and Workgroup Modular Storage systems can function for the same types of lower-priority applications as listed in the above section. When the environment is a mix of mainframe and open systems and direct IBM® z/OS® connectivity is required, Adaptable Modular Storage and Workgroup Modular Storage products must be attached to the NSC55 or a Universal Storage Platform model to host mainframe data. For smaller organizations, workgroups, or departments in large companies, branch offices, or retail outlets, an Adaptable Modular Storage or Workgroup Modular Storage system can function as a self-contained data center. Fibre Channel disks can be designated as first-tier storage and second-tier storage as SATA drives. Tunable cache partitioning and tiered-storage management software from Hitachi Data Systems make these system configurations as powerful as many competitive enterprise-class products. An AMS200 in a full-height rack has even been described as a “data center in a rack” for smaller organizations or workgroups. The Hitachi Data Systems product positioning, from the high-end enterprise to the workgroup, is shown in Figure 1.

A “Mix and Match” Modular Architecture

The Hitachi modular storage systems offer the features and functions of high-end Hitachi storage, except on a smaller scale. With the new product set, you get the same enterprise-level functionality but in a smaller package, not reduced functionality in a smaller package as is commonly offered by other industry vendors. Unlike competitive products, these new Hitachi systems can be repurposed over time. Initially, they can be used as either the primary tier of storage in a smaller organization or as first-tier expansion or second- or third-tier storage in a larger enterprise. As a small business grows or as a large enterprise completes system upgrades, Hitachi modular systems can be redeployed from the data center to a rapidly growing sales office or be moved to a Universal Storage Platform as second-tier storage. For any kind of repurposing, the reusable mix-and-match modular architecture of Hitachi modular storage is hard to beat for investment protection.

Keeping storage investment costs in mind, Hitachi Data Systems Global Solution Services offerings, such as the Risk Analysis Workshop and the Storage Economics Strategy Service, help you assess your current environment and requirements. For example, the Storage Economics Strategy Service helps you to objectively assess your current storage environment and make tactical and strategic plans to take advantage of new storage architectures. Further, it employs the HiReturn™ investment analysis program to help you consider both total cost of ownership (TCO) and return on investment (ROI) approaches.

Adaptable Modular Storage Models AMS200, AMS500, and AMS1000: the

“Mixable SATA and Fibre Channel” Storage Systems

Adaptable Modular Storage systems can serve as both the first tier (Fibre Channel disks) and second tier (SATA disks) of storage for workgroups or midsize companies, providing a self-contained “tiered” Application Optimized Storage solution in a single system. Adaptable Modular Storage systems are intended for consolidated heterogeneous open systems computing environments and for applications in e-commerce and Web serving. As in all Hitachi TagmaStore modular systems, cache partitioning allows applications with different-sized data blocks to be precisely tuned while they are hosted on the same system. This increases cache efficiency to many times that of the competition.

The Adaptable Modular Storage models AMS200, AMS500, and AMS1000 are the most scalable high-performance, high-availability systems in their category. Leveraging many high-end features, such as cache partitioning and RAID-6, the AMS200, AMS500, and AMS1000 are ideal for midsize companies that are generating fast-growing amounts of data and need to meet application requirements for availability and performance in a small footprint. Midsize companies can configure these systems as components of their Application Optimized Storage solutions, by matching application requirements and the value of data to the cost of storage in consolidation or business application platform roles, or enabling cost-effective backup, tape replacement, archiving, and compliance solutions in midsize companies. In larger enterprises, the AMS200, AMS500, and AMS1000 can be deployed in tiered-storage environments, paired with the Network Storage Controller or the Universal Storage Platform.

“Hitachi has a real opportunity to gain success with its midrange storage systems,

because this segment of the market is growing so rapidly. Small, medium-sized,

and large customers should find the Hitachi WMS and AMS storage systems

attractive offerings as standalone storage systems.”

— Tony Asaro,

Senior Analyst, Enterprise Strategy Group

The AMS200, AMS500, and AMS1000 are today’s most scalable performance, high-availability modular storage systems, supporting native Fibre Channel SAN , NAS, or iSCSI workloads on high-performance Fibre Channel or cost-efficient SATA intermix drives. These models also support RAID-6 disk configurations, for even higher availability. Adaptable Modular Storage systems complement the NSC55 and the Universal Storage Platform models USP100, USP600, and USP1100, in versatile, rackmounted packages ideal for tiered-storage

configurations and hosting data with multiple performance and archiving requirements. The Adaptable Modular Storage models support advanced Hitachi cache partitioning, a unique innovation in the midrange market brought over from the Universal Storage Platform. With tunable cache block size and memory space, these modular systems amplify Application Optimized Storage solutions with many of the enterprise-level benefits of the Universal Storage Platform and Network Storage Controller, but in a smaller footprint. Examples include the following:

: : Cost-efficient storage solutions for standalone “branch office” deployment or tiered-storage

configurations built on the Universal Storage Platform or Network Storage Controller

: : Advanced features to improve the reliability and usability within any modular infrastructure

or mission-critical midsize company operation, and for specific application workloads

: : Support for native Fibre Channel SAN, NAS, or iSCSI configurations and a choice of SATA

and Fibre Channel disks, allowing you to match the value of your data to the cost of storage

: : Innovative “data center in a box” configuration, which provides a small footprint for all IT

needs in this highly reliable “glass closet” configuration

Adaptable Modular Storage models offer a variety of features and functions that address the needs of midsize organizations or the tiered-storage needs of the enterprise. “Single pane of glass” management of all Hitachi storage is provided by Hitachi Storage Management and HiCommand® Suite software. Adaptable Modular Storage models provide simplified software for quick and easy configuration and management. Further, the product line is the only one in the industry to offer cache partitioning to allow businesses to more efficiently allocate cache to specific applications, thereby optimizing their performance. For connectivity, native NAS and iSCSI support allows IP-based volumes and files to be managed with the same tools as SAN volumes, thereby reducing management overhead. RAID-6 dual parity striping provides greater availability and flexibility in RAID group “rebuild” options than any competitor’s and protects against the rare event of a hard disk drive problem. All Adaptable Modular Storage models offer mixable SATA and Fibre Channel disk drives to allow workloads to be hosted on the most economical storage, based on assigned application priorities. Finally, redundant, hot-swappable components and the Hi-Track® “call-home” service/remote maintenance tool support

maximum uptime.

“ The Workgroup Modular Storage and the Adaptable Modular Storage families

introduce next-generation modular platforms capable of supporting RAID-6,

logical cache partitioning, and Fibre Channel plus IP network attachment via

embedded NAS gateways and iSCSI ports.”

— “Hitachi Data Systems Shakes the Midrange,” a Data Mobility Group research note by John Webster

(16)

Workgroup Modular Storage Model WMS100: the “All-SATA” Storage System

The entry-level, SATA-based WMS100 offers high-capacity, easy-to-install data storage ideal for midsize companies. The WMS100 provides the foundation for Application Optimized Storage solutions, matching requirements for cost-effective scalability and performance in a small footprint while maintaining the reliability edge provided by Hitachi engineering. This model may be considered, for example, for a business deploying its first SAN to move from inefficient and costly server-internal or server-attached storage to a centralized easy-to-manage configuration, or a business with fast-growing Microsoft Exchange or database applications. For larger companies, the WMS100 complements Adaptable Modular Storage, Universal Storage Platform, and Network Storage Controller in tiered-storage deployments, which require common management tools, nearline backup, and data movement for data lifecycle management applications. For a midsize company, workgroup, or enterprise that requires the best in scalability in a small footprint, the WMS100 supports cost-efficient SATA drives while maintaining the performance and reliability edge that world-class Hitachi engineering delivers. The WMS100 is perfect for applications lending themselves to modular workloads, especially where a SATA option is a good fit, such as the following:

: : Small Microsoft Exchange operations that require optimized storage

: : Small enterprise resource planning (ERP) and customer relationship management (CRM)

systems with midsize workloads

: : Database applications with low to moderate workload characteristics

In addition, the WMS100 provides advanced Hitachi cache partitioning, which uniquely allows the midsize company or workgroup to precisely allocate cache and tailor block size to specific applications, thereby optimizing their performance. Redundant, hot-swappable components and remote monitoring through the Hi-Track tool provide unmatched uptime for this entry-level package.

The WMS100 also serves a dual role as second- or third-tier storage for the enterprise in its maximum configuration: 41.3TB with 400GB SATA drives. This configuration can result in major capital expense (CapEx) and operational expense (OpEx) savings for enterprises in tiered open system and mainframe backup solutions using the WMS100 for enterprise disk replacement or even tape replacement. Using remote disk-to-disk replication capabilities, enterprises are finding that tape replacement can be cost-effective; it reduces the operating expense and hassle of daily tape backup and the expense of sending monthly truckloads of tape to remote sites for storage.

(17)

Adaptable Modular Storage, Workgroup Modular Storage, and third-party storage systems connect to the Universal Storage Platform or Network Storage Controller through the innovative, integrated Hitachi virtualization layer. This layer is managed in the controller, not in a separate network appliance as is the case with competitive solutions2_{. With Hitachi Universal}

Replicator software, copies of data can be moved freely anywhere in the Hitachi managed storage pools. Local data can be moved to remote sites, and mainframe data can be moved from enterprise storage disks on one vendor’s system to SATA disks on an Adaptable Modular Storage or Workgroup Modular Storage system. In this way, enterprise storage administrators control all tiers of storage and can move them freely between any equipment in the Application Optimized Storage solution, whether the storage systems are from Hitachi, EMC, IBM, or HP. This is accomplished through a common application-programming interface (API) for all platforms and logical partitioning of storage resources. All Hitachi products support Universal Replicator software, bringing the advantages of intelligent centralized management in affordable, easy-to-grow packages to businesses of all sizes.

All Hitachi modular products are supported by unique Hitachi heterogeneous virtualization technology as externally attached storage controlled by Universal Volume Manager software and Hitachi Virtual Partition Manager software running on the Network Storage Controller or the Universal Storage Platform. This allows both small and large enterprises to greatly simplify and consolidate the management of all storage on the floor, gaining the intelligence of automated management in affordable, easy-to-grow packages. Hitachi modular software capabilities are discussed in more detail in Chapter 4.

Modular Hitachi Architectures Lead the Industry

in Performance

Custom high-performance logical processor chip sets are at the heart of the Adaptable Modular Storage and Workgroup Modular Storage high-performance RAID architecture. For all Hitachi modular storage systems, I/O processor chips perform all RAID functions in silicon, and advanced cache algorithms optimize performance, offering cache partitioning that puts Hitachi architectures generations ahead of the competition. In addition, logic-assist processors support Hitachi ShadowImage™ In-System Replication software, Hitachi TrueCopy™ Extended Distance software (available on the AMS1000 and the AMS500), Hitachi TrueCopy Synchronous software, and Copy-on-Write Snapshot software, and provide self-checking of the system.

Hitachi modular storage systems offer Fibre Channel connectivity (1-, 2-, or 4-Gbit/sec throughput) and a full range of front-end host attachments, as described in Chapter 4. These modular storage architectures support fault-tolerant disk controllers, in keeping with completely redundant design principles employed by Hitachi. The redundant controllers are linked with twin high-speed connections that are about five times as fast as competitive offerings. This ensures extremely fast operation along with controller failover in the case of component failure for uninterrupted operation.

Application Optimized Storage Strategy

When creating Application Optimized Storage solutions, Hitachi Data Systems looked at IT challenges from the customer viewpoint for businesses of all sizes, including large enterprises, smaller organizations, and workgroups. In the process, it became clear that businesses of all sizes in nearly every industry face several major issues:

: : Optimizing operational efficiency is important to survival in a competitive climate.

: : Corporate governance and compliance concerns are changing the way many businesses

operate.

: : Risk preparedness and business continuity planning are not only good business practices

but are also now mandated in several industries.

FORTUNE 100 companies often have large IT organizations to wrestle with these problems, yet the same challenges face all kinds of businesses. In addition, it was clear that these issues affect all business-functional departments, including finance, human resources, sales, marketing, and product development.

Hitachi Data Systems worked with IT managers to build, manage, and adapt a storage infrastructure that supported these objectives. This gave rise to the Application Optimized Storage framework, depicted in Figure 2.

As Figure 2 illustrates, IT intersects with business objectives at applications—the moment of truth in terms of a technology system’s ability to support business requirements. Keeping applications up and running at acceptable performance levels and bringing new applications online to support business objectives are the main tasks of IT departments. Yet keeping applications up and running requires IT to provide a variety of content, data, and storage services that are usually obscured from business users. Indeed, application services and all the underlying IT support functions are the lifeblood of a business, essential to operational efficiency, compliance, and business continuity.

“ The combination of the new cost-effective Workgroup Modular Storage and

Adaptable Modular Storage midrange storage systems with scalable capacity

and the Hitachi Universal Storage Platform and Network Storage Controller

enables an intelligent tiered-storage network that will ultimately reduce cost

and complexity within the data center.”

Senior Analyst, Enterprise Strategy Group

Bringing Application Optimized Storage Solutions to

the Midrange

All Hitachi Data Systems solutions are based on the Application Optimized Storage strategy, which matches business application priorities to storage infrastructure. Regardless of organization size, the process of aligning business objectives and IT storage considerations is the same. Business managers need to set business objectives, and IT managers need to translate these business objectives into application priorities in terms of:

: : Price

: : Performance

: : Availability

: : Functionality

Application priorities are mapped to storage tiers that are established by agreement between IT and business managers. The storage tiers place different classes of data on different tiers of storage, based on the data value, the type of data, and whether the data is operational or referential. Storage management personnel then tune applications individually on each storage tier. Tiers can differ for each business and each application, large or small. It is only a matter of scale. A smaller organization might have only a few tiers, whereas a large enterprise might have many more3_.

The “all Fibre” NSC55 offers all features of the Universal Storage Platform, including external storage virtualization. The “mix-and-match Fibre and SATA” AMS500 supports high-performance, high-capacity, and high-connectivity features that make it perfect for information-intensive industries such as oil exploration, life sciences, health care, and rich media. The smaller models— the AMS200 entry-level storage deck and the SATA-based WMS100—are ideal for standalone deployment in retail outlets, business franchises, and professional offices. In fact, the low-end models can be combined with small-business servers in a full-height rackmount cabinet for a compact “data-center-in-a-rack” configuration. An example of an Application Optimized Storage solution is shown in Figure 3.

Application Optimized

Storage™ Solutions

With the introduction of modular storage systems, Hitachi Data Systems opened new possibilities for midsize companies as well as large enterprises to better align storage infrastructure with application and business needs. The Hitachi TagmaStore® Adaptable Modular Storage models AMS200, AMS500, and AMS1000, and the Workgroup Modular Storage model WMS100 play important roles in building Application Optimized Storage™ solutions from Hitachi Data Systems, which match application requirements—such as performance, availability, functionality, and cost— to storage attributes, regardless of organization size.

Previously, the answer to size differences in organizations was to group storage system size, such as high-end or midrange, and then apply solutions based on these system sizes, with fewer features for smaller companies. The Application Optimized Storage framework takes a completely different approach. Instead of offering different products for different-sized organizations, the Hitachi approach is to use the same set of building-block products to focus on the same framework for aligning IT and business objectives, whether for an enterprise or a smaller organization. In this way, the Application Optimized Storage framework leads to solutions that employ Hitachi modular systems in a tiered-storage architecture that addresses data protection and backup, storage growth, and consolidation requirements, regardless of business size. This approach makes the same quality and data availability standards found in systems that power the world’s largest banks available to smaller organizations.

“ HDS, with its new midrange storage solutions, is developing a broad portfolio

of solutions that addresses the unique business needs of midsized organizations.

It delivers a set of solutions that supports consolidated, networked storage, enables

cost-effective replication, supports long-term data archiving; and addresses the

specific storage management challenges of IT managers at mid-sized organizations.”

The Strategic Shift to a Solution Focus and Systematic

Purchase Justification

Initiated with the September 7, 2004, announcement of the Universal Storage Platform and reinforced with the July 11, 2005, announcement of the new Hitachi modular storage systems, Hitachi Data Systems has shifted to a solutions focus. This was done to further deliver on the Hitachi Data Systems Application Optimized Storage strategy and was occasioned, in part, by a survey conducted by the Storage Networking Industry Association (SNIA) End User Council in May 2004. Hitachi Data Systems wanted to align all products, software, and services in a way compatible with how users think of their storage challenges. Because storage and storage networking underlie all applications, they can either impede or enhance the ability of IT departments to support business initiatives. The Hitachi Data Systems solutions focus was designed, therefore, to directly address all Top Ten pain points in the context of the Application Optimized Storage framework4_.

4 A specific mapping of how Hitachi Data Systems solutions solve all Top Ten pain points can be found in Appendix B of this guide.

solutions framework,

regardless of

organization size.

of scale.

(23)

As part of this strategic shift, Hitachi Data Systems storage hardware, software, and services would no longer be sold separately; rather, they would be sold as packaged “solutions” tailored specifically to help organizations solve business problems. This new solutions focus is

championed by Hitachi Data Systems Global Solution Services (GSS), which provides various service options to help organizations of all sizes asses their storage environment and

requirements. GSS services can help you gain storage solution financial justifications based on solid ROI/TCO methodologies via the HiReturn™ investment analysis program. With this new solutions focus and systematic purchase justification, you can successfully analyze, justify, implement, and track storage investments as you would any other important business investment. Hitachi Data Systems has long recognized that business success is highly dependent on intelligent IT investment decisions and that storage needs to do its part. To tie it all together and to implement an integrated framework of hardware, software, and related services, Hitachi Data Systems offers comprehensive approaches to Application Optimized Storage solutions. Two major solution areas are Infrastructure Simplification, and Business Continuity and Disaster Recovery. Adaptable and differentially priced, these solutions match business-application requirements to different classes (tiers) of storage for organizations of different sizes, using the same set of Hitachi products, software, and services. Tightly integrated through common management and external virtualization, Application Optimized Storage solutions fully leverage an organization’s current storage investments while better aligning them for future growth, using best-practices financial methodologies.

Infrastructure Simplification

Hitachi Data Systems approaches Infrastructure Simplification with solutions that enable an organization, regardless of size, to dramatically reduce TCO for all storage in all locations and realize both hard and soft CapEx savings and hard and soft OpEx savings. What is most important for economic decision makers5_{to know is that building a simplified, tiered,}

consolidated, and aggregated Hitachi-enabled storage infrastructure can almost always be justified based on reduced cost of ownership (hard dollar cost savings). Not only will

Infrastructure Simplification solutions save money through consolidation and aggregation but they will also save money through tiered-storage solutions for regulatory compliance and optimized storage costs based on application business requirements. A summary of the Infrastructure Simplification solution elements and investment benefits is shown in Table 2.

Consolidation Solutions

Consolidation refers to placing open system, mainframe, or mixed workloads onto fewer

storage systems. For example, you could “consolidate” six systems down to two. For these solutions, the Hitachi modular systems’ hardware and software offer the best high-availability/ high-performance choices in the industry.

Hitachi Data Systems has been very successful in offering the cost benefits of single-system workload consolidation with Universal Storage Platforms and Network Storage Controllers for high-end enterprises and with Adaptable Modular Storage and Workgroup Modular Storage systems for midsize companies. Hitachi products are technically superior; no other vendor offers single-system workload consolidation with comparable benefits. The entire Hitachi product range allows homogeneous or mixed workloads for all major open and mainframe operating systems to reside on a single Hitachi system selected according to the size of the enterprise. With Hitachi products, organizations can:

: : Consolidate workloads from a single type of open systems server to a single Hitachi

platform

: : Consolidate workloads from a single type of mainframe server to a single Hitachi platform

(Universal Storage Platform or Network Storage Controller models)

Consolidation of both open and mainframe workloads to a single Hitachi system allows the Application Optimized Storage solution to fully integrate Hitachi software point products and service tools in a tiered-storage environment.

Data Lifecycle Solutions

Even small businesses can be required to archive e-mail messages and comply with many regulatory rules and practices related to the data lifecycle. GSS designs and implements solutions that address current and emerging storage-intensive demands such as data lifecycle management, which can reduce the pain caused by the runaway growth of all data types. One example is e-mail, which is causing problems for everyone from CEOs and CFOs to e-mail administrators and users faced with “mailbox size limit exceeded” messages. At the same time, tough new regulations are forcing organizations to retain messages and other business documents in a tamperproof, disaster-proof form for specified periods and to be able to produce them on demand. Ideally, mainstream storage and existing business continuity practices can be leveraged rather than incurring the expense of managing special-purpose hardware. Figure 5 illustrates the Hitachi Data Systems strategy of policy-based data movement from high-cost, fast-response storage systems to lower-cost, slower-response storage systems as the frequency of access and the retention value of the data decrease over time.

Figure 5. Data is moved automatically throughout its lifecycle.

Data lifecycle management solutions for Hitachi modular storage systems include:

Hitachi Message Archive for E-mail Solution

The Message Archive for E-mail solution leverages the standard Hitachi archival platform to provide automatic and selective document archiving, along with search-and-retrieval capabilities and audit trails. Figure 6 illustrates how e-mail archiving works in the data lifecycle. When data is introduced to the archive, a digital signature is assigned to uniquely identify the object and make sure it has not been tampered with. The object is then indexed, and metadata is created to describe the object in the message archive’s metadata store. Metadata is information about the data that is used in populating, maintaining, and accessing both the descriptive information that identifies the archive’s holdings and the administrative data used to manage the archive. In the Message Archive for E-mail, the only metadata needed might be the sender, date and time sent, subject line, and information about any attachments (file name, size). In addition to providing users with a view of archived information, the solution seamlessly integrates into the client interface for Microsoft Outlook and Lotus Notes. Importantly, it eliminates “mailbox limit exceeded” problems, effectively expanding overall storage capacity for your e-mail users.
