Executive Overview
Hewlett-Packard is pleased to submit to MediaMasters this Corporate Storage Area Network proposal.
MediaMaster’s reputation for being the fastest, most on-time media publishing company can be maintained into the future by providing the multimedia editing and manufacturing environment and its ever increasing storage demands with a high performance, highly fault-tolerant storage networking infrastructure. It should include HP SureGear
hardware, HP SureSoft software, HP SureSpan infrastructure, HP SureDesign consulting. and HP SureGuide services.
Several alternatives are possible because of the wide range of solutions HP offers through the HP Equation Architecture. The solutions that meet the various needs of
MediaMasters includes HP SureStore E Fibre Channel bridges, HP ProCurve and HP AdvanceStack switches, Brocade Fibre Channel switches, HP SureStore E disk arrays and tape libraries, and HP storage management and backup software. Fault tolerance is provided in each of the alternatives by redundancy in key components: array controllers, power supplies, batteries, Fibre Channel and Gigabit links, fans, etc. Ease of
maintenance is accomplished with hot-swappable modules and power supplies. With Hewlett-Packard SureStore E enterprise storage solutions as the foundation of the storage network, up to 1TB of data can be configured to meet MediaMasters storage requirements today and can then scale into the future to accommodate the expected tenfold growth by the end of 2001. Key to this scalable solution is storage management and HP SureStore E SAN Manager DM device management and SAN Manager LM LUN management bring these benefits to MediaMasters.
With the Disk Array FC60 you get the highest performance so necessary in the data warehousing of the large 200MB to 20GB files required by MediaMasters.
The Disk Array XP256, however, is offered as the most easily managed and scalable solution for NT consolidation and heterogeneous connectivity. MediaMaster’s backup strategy can also be simplified and security can be enhanced. The HP SureStore E Disk Array XP256 is the most highly-available, cost-effective, multi-platform high-end disk array on the market, with ample power to handle all MediaMasters mission-critical data and applications. The XP256 offers fully scalable, modular solutions that provide stress-free storage up to 11TB. The XP256 offers flexible configurations, high capacity, scalability and performance including full software and solution integration. Broad, Fibre Channel attached, heterogeneous server support. Host failover and alternate path support. The XP256 comes complete with a comprehensive software suite that provides unequaled value with functionality.
A LAN component has been included as it is essential to the overall performance of MediaMaster’s multimedia production objectives and HP provides both SAN and LAN solutions tuned and optimized for economy, performance, management and scalability. Therefore, we will provide two options: One optimized for cost and performance (“the biggest bang for the buck”) and one for the ultimate in high availability, management and scalability.
Hewlett-Packard also offers an extensive array of service and support products to ensure the network will be running at peak performance through its 24 x 7, 365 days a year operation. Given MediaMasters in-house technical expertise, MediaMasters can choose just the level of support it needs.
Finally, we are proud to offer ediaMasters our first ever WRITTEN 100% satisfaction guarantee. It is comprised of a 90-day refund or replacement for any reason from the date of receipt and applies to all HP-branded enterprise-storage hardware. This is a storage-specific guarantee that complements HP’s existing 99.95% High Availability System-Wide Uptime commitment for a complete enterprise-computing environment.

Vendor Description

Technical Solution Description
The data load for MediaMasters has quadrupled annually. Multiple servers connected to many gigabytes or terabytes of disk storage are commonly used to facilitate the flow of data. With increasing interdependence of information in MediaMasters infrastructure, each application must take data from some servers and give data to others. Local area networks (LANs) are inadequate for moving the large quantities of data accumulated at the server level.
Hewlett-Packard recognizes that MediaMasters must have a storage solution that will enable it to deliver a quality product, on time, to its customers.Providing the fastest service has made MediaMasters the leader in the media publishing business.This desired position requires highly talented individuals, and resources that can be counted on to be available around the clock. This storage-centric environment must satisfy needs at the user, data center, and business management levels.
5.1.1
MediaMasters Requirements
To maintain its competitive advantage, MediaMasters wants to implement a resilient, high-performance, storage area network backbone that will sustain a peak-level
production environment and data load growth, into the foreseeable future.MediaMasters needs high availability. The editors and production staff require performance and uptime, all the time, any time. It is the responsibility of the data center to provide highly reliable resources in an environment that remains flexible and reusable as the business grows. MediaMasters also requires continuity of operations 24 hour a day, seven days a week; integration of data and applications for decision support and planning; and operational support from a reliable systems vendor.
For this SAN implementation, MediaMasters has identified some absolute requirements that need to be addressed:
1) Heterogeneous connectivity
2) Fault-tolerant and resilient Storage Area Network 3) LAN Gigabit backbone
4) Performance is crucial 5) New tape library required 6) Current network backup strategy 7) 100 Mbps switched to the desktop 8) Scalability storage
9) Cost competitive
The measure of whether a storage area network will meet the high demands placed on it by MediaMasters high volume, and high-availability requirements, is dependent two issues – the throughput of the SAN and the performance of the arrays. Hewlett-Packard recommends that this implementation have the following minimum characteristics:
High aggregate throughput at the array for performance
Non-blocking switching architecture
Fibre Channel-attached storage replacing the existing SCSI-attached
Redundancy in key components for high availability
Hot-swappable components
Open standards-based focus, ensuring investment protection by guaranteeing interoperability.
Storage management tools to control data
Storage vendor can deliver exceptional warranty and support
The Hewlett-Packard recommendation is to create a Fibre Channel switched fabric using the Brocade Silkworm 2800. This high-performance Fibre Channel switch has the following feature highlights (please refer to the product data sheet in Section 8 Product Literature for additional specifications):
Capacity for up to 16 Fibre Channel ports
Up to 16 Gbps aggregate bandwidth full duplex
High speed connections at substantial distances (up to 16 km)
Up to 32 switches can be linked together
Optional zoning capability
Redundant power supplies and fans
Hot-swappable power supplies and interface modules
SNMP manageable
HP worldwide service and support
Next, replacing the existing direct-attached storage with Fibre Channel-attached storage is recommended. This can be accomplished with the Disk Array FC60 or the Disk Array XP256. Both will result in a consolidation of servers and centralization of storage and management. In addition, the FC60 can be implemented as distributed storage to balance network loads if needed.
The price/performance proposal is the recommended solution due to the fact that MediaMasters business requirements as a multimedia production company can best be met with a high performance solution. The throughput of the multiple FC60s on a Fibre Channel network will continue to increase as the storage network grows and more FC60 frames are added in the future. Performance stays high
With the Management and Security solution the single array will scale infinitely and is easier to implement, manage, and control, but is limited by the internal bus speed of the single array to about 180MB/s. Once this limit is reached a performance bottleneck may be experienced, but an analysis of the applications and expected IOPS can determine if this is the case and is part of HP’s SureDesign consulting capability.
5.1.2
Solution Description Through HP Equation Architecture
HP will use the HP Equation architecture for intelligent, open storage and
HP SureStore E products in completing the SAN solution for MediaMasters. Our vision for Equation is an open pool of storage that safely and efficiently provides 100% data availability and infinite scalability

• SureSoft Software (storage management)
• SureSpan Fabric (FC switch, hub, bridge infrastructure)
• SureGuide Services (consulting and support)
• SureDesign Solutions (Bundles of hardware, software and services to solve specific customer issues)
SureStore E is the brand name for our products, services, and solutions
5.1.2.1 Price / Performance SAN Design
The Hewlett-Packard solution calls creating a separate network on the MediaMaster’s campus, with two Fibre Channel switches located in each of the three buildings. The two buildings adjacent to one another can be connected via shortwave Fibre Channel as the distance is assumed to be no more than 500 meters. The remote site, at approximately five miles distance can be connected through the SAN via longwave Fiber Channel connections and the server’s LAN connections will be upgraded to FDDI (refer to Section 2, page 5, Storage Data-Center Diagram).
Every server in each of the buildings is connected to both Brocade Silkworm 2800 Fibre Channel Switches in that building. The switches in buildings B and C are then connected to one of the two switches in building A. To provide additional capacity and fault tolerance, each switch can linked to both switches in building A as an optional configuration. HP SureDesign Solutions HP SureSoft Software HP SureGear Hardware HP SureSpan Fabric HP SureGuide Services + + + +
Longwave connections have been specified in the switches where the fiber cable runs are longer than the recommended 500m for shortwave fibre channel. This satisfies the distance requirements for building C.
5.2.2.2 Building A Configuration
A total of nine servers exist in building A. These servers have been consolidated and each is connected to two 16-port Brocade Silkworm 2800 Fibre Channel switches using two Fibre Channel host bus adapters (HBAs) in each server as illustrated below. Nine shortwave GBIC connections on each switch connect to each of the servers.
Figure 5.2.2.2a Host Fibre Channel Connection
In the original MediaMaster’s network, the backbone arrangement switched 10Mbps connections to all servers and workstations connections. Hewlett-Packard agrees with MediaMaster’s that these connections should be replaced with 100Mbps Ethernet connections, including the servers for optimum performance, especially for backup. The 15 SUN Solaris workstations in the multimedia lab will be upgraded with 10/100Mbps Ethernet cards and connected to the ProCurve 4000M 10/100Mbps switches.
Seven of these servers are then connected to two HP ProCurve 4000M 10/100Mbps switches via two 10/100Mbps Ethernet cards in every server in much the same fashion as the FC switches. The two Web servers, however, will be connected directly to the existing firewall so that no incoming communication passes to the internal
MediaMaster’s Ethernet company LAN. Complete security on the Fibre Channel SAN, however, is accomplished by SAN Manager LM and zoning options on the switches creating virtual SANs. The servers are then easily managed from a centralized location and complete redundancy has been created so that should any single HBA or Ethernet card fail, or a data cable be disconnected or damaged, access to both the SAN and the LAN are still assured.
The SUN workstations in the multimedia labs will be upgrade to 100Mbps and link directly into the LAN, and access the storage the same as if they were accessing direct attached SCSI storage through the servers.
Figure 5.2.2.2b 10/100Mbps LAN Implementation
Storage is consolidated by redeploying the existing direct-attached SCSI disks and tape libraries to non-mission-critical applications and replacing them with Fibre Channel attached SureStore E Disk Array FC60 storage systems.
Two arrays are recommended and each has dual controllers for fault tolerance and performance. One controller in each array will be connected to Switch And the other to the Switch B, again for fault resilience. See figure5.2.2.2) The key for MediaMasters will be redundancy all the way from the LAN backbone to the data. The data is split between the two arrays and the throughput at the arrays essentially doubles to about 360MB/s. This accomplishes the high performance requirement and is scalable. When additional storage is needed, only disk mechanisms need to be purchased to fully populate the FC60 arrays. When they are full, additional FC60 will added seamlessly to the storage network.

5.2.2.3 Building B Configuration
The SAN infrastructure for building B is similar in that there are two Brocade Silkworm 2800 Fibre Channel switches, but only four severs are connected via shortwave GBICs. Since building B is assumed to be less than 500 meters, distant short Fibre channel is used to connect the switches in building B to building A. These four servers are also connected to two HP ProCurve Switch 4000Ms in the same manner as in building A. Dual connections are possible from each switch, but HP has used only one connection per switch for simplicity and still there are dual paths from any server in building B to the switches and storage in building B. See Figure 5.2.2.3

The SAN at the headquarters campus, consisting of building A and B, will be connected through shortwave Fibre Channel and building C, the remote site, via longwave
connections on the Fibre Channel switches as depicted in the figure below. The LAN connection will be Gigabit Ethernet fiber optic links and building C will utilize the HP AdvanceStack Switch 2000 to link the 100Mbps Ethernet network to and FDDI link.

Management and Security Solution SAN Design
This solution is a storage consolidation alternative in conjunction with the server consolidation described in the price / performance SAN design. The XP256 configured with enough storage to meet the initial requirement of 3.25TB and scalable to 11TB will be used instead of distributed FC60s.
The server to FC switch connection will be accomplished with 3 Brocade 2800 FC Switches since we will need the additional port count for multiple XP256 links and the SUN workstations. Step 2 involves connecting the servers to the LAN via dual HP ProCurve Routing Switch 9304. This provides not only a Gigabit Ethernet backbone between buildings A and B, but to all the servers as well. This is important when increasing the performance of the SAN and for backup applications that run over the LAN.
Figure 5.2.3a shows the Gigabit connections and Fibre Channel connections in the sever environment in building A. However, he SUN workstations now access the storage network directly through the FC Channel switches with FC HBAs since the XP256 supports the Solaris operating system through the switch.

Attachment of the HP SureStore E Tape Library 20/700 will be provided through three Fibre Channel to SCSI bridging devices that connect four SCSI ports to two Fibre Channel links into the SAN. Each SCSI port attaches to one DLT 9430 Tape Drive mechanism in the tape library. (See above diagram).

HP SureStore E SAN Manager DM
MediaMasters SAN will be configured controlled and managed via HP SureStore E SAN Manager DM and LM software. SAN Manager DM manages the physical devices and launches device management applications and SAN Manager LM manages the security and logical configuration of MediaMasters data.
6.1.1.1 Discovery and Mapping of the SAN
SAN Manager DM automatically discovers devices that are part of the SAN topology, including server-based Fibre Channel host bus adapters (HBAs), interconnecting devices (hubs, switches, etc.) and storage devices. These devices are mapped in an intuitive graphical format at a central console, providing IT operators with virtually instant visibility into the SAN. All aspects of the SAN are displayed, including redundant
connections between devices. Continual automatic discovery assures that changes in the SAN are immediately identified and mapped.
As is often the case with new technology, manageability interface standards have not yet been established for Fibre Channel SAN devices. SAN Manager DM ensures that even unmanaged devices are represented on the network map by allowing these devices to be added manually.
The automatically generated map of the SAN shows all physical connections between devices. This map can be customized into views with drag and drop simplicity, so icons are grouped and more accurately reflect their geographical distribution. Once created, custom views can be saved for future us.
Drill-down, pan and zoom and other graphical display features are offered to give IT operators a more detailed view of any aspect of the SAN.
6.1.2 SAN Manager LM
6.1.2.1 High-Bandwidth Storage Network Architecture
A storage area network (SAN) is a high-speed, high-bandwidth storage network architecture designed to address many of the problems associated with the current proliferation of servers and storage. With integrated hardware and software, and a robust, high-speed backbone, SANs enable clusters of servers to share storage arrays.
Advanced SAN features can help MediaMasters increase server performance, optimize storage usage, and enhance high availability features such as failover, load balancing, and distributed applications. SANs can also reduce the cost of storage administration by allowing efficient data consolidation. SANs are beneficial for data warehousing, online transaction processing, data backup and restoration, Web serving, and high availability, enterprise-wide storage management. Wherever there are multiple servers and mass storage, a SAN can provide MediaMasters a high-performing, flexible and efficient way to configure and manage storage.
Routine management tasks, such as upgrading a server that has run out of storage capacity, are expensive and time-consuming. Before SANs, an IT manager had to purchase new storage or move it from another server. Either way, one or more servers had to be taken offline for the change.
Hewlett-Packard (HP) has simplified storage management tasks by enabling
MediaMasters to efficiently allocate storage resources among servers. With HP SureStore E SAN Manager LM, MediaMasters IT manager simply opens the SAN administration tool, views available storage logical unit numbers (LUNs). It reassigns storage where it is needed, without additional cost and loss of storage availability all without reboots. HP SureStore E SAN Manager LM is a software product that enables MediaMasters IT Professionals to manage fibre channel-attached storage in a highly efficient manner. HP SAN Manager LM enables heterogeneous or homogeneous systems to use a common pool of storage devices on a storage area network.
Through a simple drag-and-drop interface, MediaMasters administrators can add storage to a pool or assign it to nodes (servers). Storage is available for immediate use because it
6.1.2.2 HP SureStore E SAN Manager LM Features

Figure 5.1. HP SAN Manager LM User Interface
6.1.2.3 Reduced Administrative Costs
HP SureStore E SAN Manager LM can reduce MediaMasters total cost of ownership by simplifying storage administration. All storage and computer nodes on the SAN are presented to the administrator as a single system image. This single, unified view provides control over all the SAN storage assets. Therefore, storage can be added or moved without physically reconfiguring the entire network. In a matter of minutes, storage can be assigned when and where it is needed.
Administration time is significantly reduced through automatic discovery, automatic mounting when assigned storage comes online, and filtered views of the SAN.
Storage area networks are easy to configure and manage with HP SAN Manager LM. Auto discovery is used to identify nodes and storage, which speeds configuration, provides accuracy, and saves MediaMasters administrator from manually entering information.
Storage is organized into logical groups and can be assigned and managed in a uniform manner. Assignment of storage is accomplished by simply selecting individual devices, or a group of devices, and then dragging them to the desired node.
6.1.2.5 Storage Asset Pool Creation
HP SureStore E SAN Manager LM creates a storage asset pool for administrative
clustering that allows storage LUNs to be assigned exclusively and securely to designated server nodes on the SAN. The assignments are made dynamically so that storage and node changes can occur without network disruption.
6.1.2.6 Single System Image
MediaMasters has a single system image that permits viewing, managing, and assigning all nodes and storage subsystems.
6.1.2.7 Storage Assignment
Storage LUNs are recognized on the real LUN level and may be assigned to servers as required. LUN level access enables storage assignment on a highly granular basis, allowing efficient allocation of storage assets.
6.1.2.8 Availability
With HP SureStore E SAN Manager LM, LUNs can be assigned and reassigned dynamically without requiring servers or storage arrays to reboot providing 100 percent availability during SAN administrative procedures.
6.1.2.9 Scalability
Up to 16,000 LUNs and a maximum of 200 server nodes can be configured on a single SAN for superior system scalability.
6.1.2.10 Data Security
HP SureStore E SAN Manager LM only allows servers to mount and access storage exclusively assigned to them. In conjunction with the server’s underlying network operating system security, this restricted access mechanism provides solid security for SAN assets. Additionally, servers may be permitted or denied access to the SAN.
HP SureStore E SAN Manager LM’s "any-to-any" architecture provides exclusive assignment of any LUN to any node. Heterogeneous servers can share storage arrays because HP SureStore E SAN Manager LM is designed to support Microsoft Windows NT, with support for SUN Solaris, and other UNIX operating systems variants on the way.
6.1.2.12 Compatible
With HP SureStore E SAN Manager LM, the following will be integrated under one umbrella for MediaMasters:

• FOXVWHUHGVHUYHUV
• ILOHV\VWHPVWRUDJHPDQDJHPHQWXWLOLWLHV
• EDFNXSUHVWRUHSURGXFWV
Network topology independence and compatibility with a wide range of Fibre Channel components enables HP SureStore E SAN Manager LM to bring it all together.
6.1.2.13 HP SureStore E SAN Manager LM Benefits for MediaMasters
HP SAN Manager LM creates a SAN subsystem with the ability to efficiently allocate storage resources among both homogeneous and heterogeneous servers. There is less need for MediaMasters to buy additional storage because existing storage is used more efficiently.
About 55 percent of the cost of storage are attributed to man-hours spent in management over the storage lifetime. According to International Data Corporation (IDC), a SAN can reduce this management time to about 15 percent. MediaMasters can expect similar results with HP SureStore E SAN Manager LM.
The SAN does not need to be powered down for maintenance and disk failures are easily alleviated without downtime through dynamic reassignment.
Traffic backups on the LAN are reduced by rerouting traffic to the SAN. Backup of servers need not occur over the LAN, increasing available bandwidth for applications and making backup time more flexible.
HP SAN Manager LM integrates transparently into the existing storage management infrastructure. Existing storage management and backup tools or utilities can be used to configure storage in the storage pool.
Storage management has evolved from an easy task to an overwhelming responsibility for system administrators. To provide access to data, when and where it is needed, requires an intelligent, flexible, cost-effective alternative that optimizes MediaMasters networking environment. HP SAN Manager LM simplifies networking with its high performance and data availability while increasing data access and data flows, without the interference of other applications.
