This session covers storage tiering from server to storage devices to Cloud.

1. New Generation of Storage Tiering:
Less management, lower investment and increased performance

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

5. Automated Sub-LUN Tiering within a Storage Array
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
Solid-State Drives

deployments with minimal costs

– Sub-LUN Automatic Movement
– Entire-LUN Manual Relocation

6. IBM Easy Tier®
Extent Pools can have mixed media
1. Solid-State Drives (SSD)
2. Enterprise HDD (15K and 10K RPM)
3. Nearline HDD (7200 RPM)
SSD RAID Array(s)
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
Enterprise HDD 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
Nearline HDD

benefits of adding SSD before purchase!

8. IBM Easy Tier® Cooperative Server Caching
To avoid performance bottlenecks over
the SAN, IBM Easy Tier® will be
extended to support server-based Flash
Server Server
• Most active data will be moved from
SAN disk system to server SSD
• Global cache statistics maintained in
the Disk array
• Applications can provide “hints”

10. Hierarchical Storage Management (HSM)
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
Hard Solution:
Disk
Drives Migrate or archive data from disk to tape
based on age and anticipate access pattern
Tape Automatically recall data back to disk when
accessed by user or application
