Information Explosion Creates Storage Challenges
How much data does mankind store?
• IDC* says about 281 exabytes in 2007
• By 2011, we’ll reach 1,773 exabytes
• That’s 600% growth in 4 years
IBM aims to provide a simple solution
for the modern enterprise’s storage
needs
281,000 PB
1,773,000 PB

IBM Information Infrastructure for Improved Availability
IBM System Storage DS8000 R4.3
Thin Provisioning with No Performance Impact*
Initialize LUNs Up To 2.6x Faster Than Previous Method
 Enhancements
Thin Provisioning, with zero performance impact compared to traditional
provisioning
Faster LUN initialization speeds deployment of new production and HA/DR
volumes
Enhancement to High Performance FICON for System z enables up to 14%
more throughput initially, and more planned.
 Business Value
Performance and efficiency enhancements extend the value advantage of
DS8000.
Supports shorter Recovery Time Objectives
The only enterprise storage with an option for drive level disk encryption
 Technical Benefit
zHPF Multitrack support means applications can read or write more than one
track's worth of data in a single transfer, removing potential I/O bottlenecks.
DS8000 has significant z/OS optimization, but also supports Linux, Unix, and
Windows
Note: Thin Provisioning and Faster volume initialization
support Linux, Unix, and Windows initially

1TB SATA 7.5k RPM Drive Support
Higher capacity nearline drives for consolidation and tiered storage
Client Value:
Near-line storage for tier-2 applications that provide lower price per IOP
 Can help consolidation efforts with
tier-2 capacity
 System is now scalable to 1,204 TB
physical capacity when fully populated
with SATA drives
1 TB physical capacity
Usable capacity is around 900 GB caused by
sector mapping
 Intermix of SATA and Enterprise Drives
is supported on the same DA pair

 Where to implement SATA drives in tier 1
storage
Customers looking for low cost per GB and willing to
take some availability risks / performance reduction
Bandwidth / streaming applications where transfer
rate is more important than seek time
Some applications with low or limited IOPS
performance requirements
 Where to implement SATA drives in tier 2
storage
Disk-based near-line storage between disk and tape
Disaster recovery target for remote replication
Fixed content / Managed Retention data
Temp work space for short-term processing

Full Disk Encryption and Key Management
Only major vendor to build media encryption into the
infrastructure … not bolted on
 Full Disk Encryption drive option (Q1 DS8000; Q2 DS5000)
Embedded encryption engine in each drive (AES 128 standard)
Data encrypted as it enters the drive and decrypted as it leaves the drive
Performance scales linearly as more drives as added, so unlike alternative
solutions, there is no performance loss
Available for fibre channel drives only (146/300/450 GB 15K RPM)
Uses same proven key management (TKLM) as IBM’s successful encrypting
tape solution
Can be used as either encrypted or non-encrypted (shipped with encryption
turned off from factory)
Protects sensitive data when drives leave the data center
Simplifies retirement or re-purposing of older systems easily and economically
Why do clients want this? Because all disk drives leave the data center

Remote Pair FlashCopy
Client Value:
More effective two-site business continuity with FlashCopy and Metro Mirror
 Helps improve data synchronization when a FlashCopy target is also a Metro Mirror source
 Prior to introduction of Remote Pair FlashCopy
The Metro Mirror pair could become temporarily “unsynchronized” and hinder a
HyperSwap operation
This became problematic if client would perform many FlashCopies throughout the day
 Remote Pair FlashCopy now keeps Metro Mirror primary and secondary volumes
synchronized during all FlashCopies
 Remote Pair FlashCopy can be combined with:
Incremental FlashCopy
Background copy or no background copy
Nocopy to copy
FlashCopy consistency groups
FlashCopy of open devices using a CKD access device
 Remote Pair FlashCopy will GA on April 24 (Plant/Field)
 No charge for Remote Pair FlashCopy
