Today’s Challenges, Tomorrow’s Opportunities
Not only ensuring high availability and quality of existing services, but also meeting customer expectations
for real-time, dynamic access to innovative new services.
IMPROVE SERVICE
Not just containing operational cost and complexity, but achieving
breakthrough productivity gains through virtualization, optimization, energy stewardship, and flexible
sourcing.
REDUCE COST
MANAGE RISKNot only addressing today’s security, and compliance challenges, but also preparing for the new risks posed by an even more connected and collaborative world.
Deliver the right information,
to the right people, at the right time …
… with an IT infrastructure in a dynamically changing
environment

Four Fundamental Truths – A Basis for Storage Tiering
� All data is not created equal
� Information changes in business value and in service level requirements over time
� IT resources should be allocated according to the value of data
� Information must be managed throughout its entire lifespan … data outlives media

Automated Sub-LUN Tiering within a Storage Array
Solid-State Drives
Enterprise HDD15K and 10K rpm
Nearline HDD7200 rpm
Problem:
� SSDs are considerably more expensive than traditional disks
� Without optimization tools, clients have been over-provisioning them
� Administrators spend too much time monitoring, reporting, and tuning tiers
Solution:
� Three data relocation functions that enable smart data placement to optimize SSD deployments with minimal costs
– Sub-LUN Automatic Movement– Entire-LUN Manual Relocation– Re-balancing Intra-Tier Extent
Pool

SSD RAID Array(s)
Enterprise HDD
Nearline HDD
� Extent Pools can have mixed media1. Solid-State Drives (SSD)2. Enterprise HDD (15K and 10K RPM)3. Nearline HDD (7200 RPM)
� Easy Tier measures and manages activity– 24 hour learning period– Every five minutes: up to 8 extents moved
• Hottest Extents moved up to SSD• Coldest Extents moved down to slowest
Disk– New allocations placed initially on fastest HDD
� A small amount of SSD (as little as 3%) can dramatically reduce response times and increase IOPS throughput
� Storage Tier Advisory Tool can estimate benefits of adding SSD before purchase!

IBM Easy Tier® Cooperative Server Caching
Server Server
SAN
To avoid performance bottlenecks over the SAN, IBM Easy Tier® will be extended to support server-based Flash
• Most active data will be moved from disk system to server SSD
• Global cache statistics maintained in the Disk array
• Applications can provide “hints”
IBM Edge 2012 Demonstration showed POWER7 server with EXP30 SSD and DS8800 Easy Tier, resulting in 5x performance boost for Filenet ECM
IBM has acquired Texas Memory Systems, and plans to offer Easy Tier support for PCiE Flash cards as well

Problem:
� High-end disk arrays are expensive
� Difficult to identify which data should be moved
� Manually re-locating LUNsis manual and disruptive
Solution:
� SmartCloud VSC can manage up to 256 arrays (IBM and non-IBM) per SmartCloudVSC cluster
� Storage Analytics Engine recommends up-tier and down-tier moves based on performance and age of the data
� Move LUNs non-disruptively within and across arrays

Hierarchical Storage Management (HSM)
Hard Disk
Drives
Tape
Problem:
� Disk faces challenges for density and has slowed to 20%
� Tape will continue to grow in Density at an average 40% CAGR
� Cost difference – Disk is 20x more expensive than Tape
Solution:
� Migrate or archive data from disk to tape based on age and anticipate access pattern
� Automatically recall data back to disk when accessed by user or application

Reduced Costs, Increased Flexibility
� Lower costs primarily from:
– Lower cost of media
– Minimal need for Power & Cooling
� Increased flexibility from ability to:
– Add capacity by simply adding Tape cartridges
– Expand Tape libraries over and around existing equipment in the data center
� Reliability: lower bit-error-rates, read verifications after writes.Tape

Drives
Problem:
� Remote offices need access to corporate data
� Corporate HQ needs access to Remote office data
� Data access across WAN can be slow or difficult to find
Solutions:
� A Cloud Storage Gateway can provide high performance access to most recently accessed data
– IBM SmartCloud Enterprise Object Storage
� IBM Active Cloud Engine provides a global namespace of all your files across all of your locations
– Hub-and-Spoke design allows a central HQ location (Hub) to work with up to 1000 remote offices (Spokes)
