Current Trends and Issues

•Threat risk challenges include:

• Acts of man and acts of nature, human error • Aging infrastructures

– Hardware, software, networks, support personal

• Compliance, BC, DR and related requirements •Consolidation – Data centers, servers, storage

(3)

Current Trends and Issues

• Proliferation of:

• Windows and NAS file servers • Servers, storage and SANs

• More data generated, copied and retained • Confusion regarding:

• Power, cooling and “Green wash” • Different forms of storage virtualization • Compliance is only for certain companies • SOHO vs. SMB vs. Enterprise vs. ROBO • Connectivity and data access options

IT Power & Cooling Fast Facts

• Data centers consumed 61 billion kWh in 2006

• 2006 U.S. data centers used 1.5% of electricity

• IT power consumption about $4.5B USD in 2006

• On average 50% of IT electricity is for cooling

• 78% of CO2 tied to electricity generation

• Emissions will vary by type of fuel being used

(Western vs. eastern coal, petroleum and natural gas, hydro, nuclear, thermo, wind)

• 24 cubic foot refrigerator is 1.22 tons of CO2/year

• Gallon of gas generates about 20lbs of CO2

• Chevrolet Tahoe produces 7 to 10 tons of CO2/year

What's the buzz?

Hard Disk Drive (HDD) Storage Trends

(6)

What's the buzz?

•Storage devices and media

• Improved reliability, lower cost and power • Larger capacity disk drives (3.5” 1TB SATA) • Smaller footprint -- enterprise 2.5” • Removable hard disk drives (RHDD) • High performance SAS (2.5” & 3.5”) disks • Tape and optical are alive with enhancements • Holographic storage is becoming available • FLASH & RAM SSD gaining momentum • Hybrid disks = Disk + FASH and/or RAM

What's the buzz?

•Storage virtualization (file, block and I/O) • Many different faces and locations

• Device emulation including virtual tape • Transparent data migration or movement

–Enable technology replacement and upgrade –Enable policy based automated data tiering • Heterogeneous data replication for BC/DR • Aggregation or pooling file systems or volumes

–Global name spaces, LUN pooling –Heterogeneous storage and file systems

Storage and File Virtualization

• Many difference faces of virtualization

• Servers, storage, networks and I/O • Resource pooling vs. emulation • Plenty of myths and realities

• Abstraction, Emulation, Aggregation • Heterogeneous functionality

Storage (Block & File) Virtualization

Confusion, Miss-alignment, Disappointment

The Good The Bad The Ugly

9Enable IT services

9Maximize IT resources

by balancing (PACE) performance, availability, capacity and energy resources

9Does not impede IT

service delivery

9No added complexity

or management cost

9Addresses various

functions and IRM related tasks

9Miss-alignment of

technology to tasks

9Using the wrong tool or technique for given task and function

9Miss-perception of what, where, when and how to deploy various forms of virtualization

9Can increase lock-in

9Increased complexity

9Management costs

9Limit interoperability

9Un-balanced resource

usage, poor service delivery, performance or scaling issues

9Disappointment from

improper expectations

9Confusion and FUD in

the market place

The Real Opportunity: Transparent Data Migration for block & file data!!!

What's the buzz?

• Data footprint = Your data + backup copies etc…

• Data footprint reduction

• Archiving (email, files, databases)

– Requires knowledge of data business value – Time consuming, requires technology and people

• Compression or compaction

– Host software, appliance or device based – Works across most applications and data types

• Single instance storage (aka de-duplication)

– Remove duplicate, repeating, recurring data or files – Stores a single copy or occurrence of data or file See free report “Business Benefits of Data Footprint Reduction”

What's the buzz?

• Security and data protection

• Application and transactional aware

• Snapshots & CDP (continuous data protection) • Disk based backup instead of tape or optical • Storage for archiving or compliance • Data protection management (DPM) • Cross technology aware event correlation • Authorization and digital shredding

•Zombie technologies -- They still are practical

• Tape and the mainframe have been on the list • Fibre Channel & FICON declared dead long ago • Disk added to Zombie list (it has a future!!!) •Virtualization is where RAID was 15 years

ago

• Server, storage and I/O virtualization

• Stability and scalability issues being addressed • Business cases can be made around migration! • Align right technology to task at hand

What You Can Do Today

•Windows file servers and other NAS

• Address proliferation of file servers • Deploy file discovery and analysis tools • Data footprint reduction and consolidation • Leverage global name spaces if applicable •Remote office branch offices (ROBO)

• Enable data protection, consolidation, DR/BC • Support remote “virtual” offices and laptops • Leverage remote backup, replication or WAFS

What You Can Do Today

• Data protection and retention (BC, DR, Archive) • Disk based data protection and archive

– Disk is a good fit for on-line and near-line – VTLs help bridge the gap for tape based processing – Tape still viable for longer term backup or archive

• Employ data protection management tools

– Look for business aware and cross domain tools – Leverage tools with event correlation analysis

• Enhance VMware with 3rdparty tools

– VCB with application aware snapshots

– Compliment VMotion with remote data replication

What You Can Do Today

• Data Security -- Logical and Physical

(10)

What You Can Do Today

• Infrastructure resource management

• Data protection and accessibility • Data migration for technology upgrades • Gain insight in to how resources are used • Virtual to consolidate, cluster to scale

• Maximize your power, cooling and green topics • Reduce your data footprint

– Single instance, compression, archive, de-dupe – Do more with what you have, data management

• Look at performance effective solutions

– Do more work with same or less watts (IOP/watt)

Closing Comments

•Continued shift from DAS to networked storage

•Storage and storage interfaces continue to evolve

•There are many facets to storage virtualizations

•VMware needs external storage for HA / BC / DR

•Reduce your data footprint and enhance security

•Several approaches exist to address power issues

•Futures are great, however, what exists today is what you can use today to address current issues!
