VISION
Provide autonomic capabilities that improve
access to and management of stored data in
an on demand world
Accomplished in a standard, open way
consistent with the SNIA Storage Model
BENEFITS
Dramatically reduced total cost of ownership
Improved organizational agility
IBM 4Q 2002 Study of SAN Customer Needs
What savings could be possible if…
1. Data migrations were non-disruptive?
2. Creating new storage for applications was easier?
3. Application failures from out of space conditions could be eliminated?
4. Data could be moved from high-cost to low-cost storage based
on policies?
5. Duplicate SAN data could be reduced through more effective
data sharing?
6. Desired disk utilization could be achieved through better storage
management?
7. SAN data could be managed from a centralized point?
8. Server and storage consolidations were easier?
9. Planned and unplanned downtime could be reduced or eliminated?

IBM 4Q 2002 Study of SAN Customer Needs
SAN Profiles
Findings – Key Needs
 88% of SANs in Data Centers
 Ability to deploy heterogeneous SANs
 Greater ability to scale
 Reduction of planned downtime
 Improve storage utilization
 Interoperability
 Protect current investment
 92% support Windows servers
 1/2 storage for Windows; 1/3 for
UNIX
 Over 50% of storage in SAN,
<50% of capacity utilized, while
>70% desired
 1 TB of excess capacity
 On average 5 SANs per
enterprise
 SAN sizes vary widely –
2 to 22TB

Storage Manager
Business Problem
 Storage growth doubling every 12-18
months
 Effectively manage costs
 Support dual vendor strategy
Solution Approach
 Increase storage utilization through
virtualization
 Introduce lower cost storage into SAN
 Improve storage admin productivity
 Increase application availability during
migrations
More Efficient Utilization of SAN Storage Capacity
SANs Today
 Shared Physical network, but capacity sharing
is very limited in heterogeneous environments
 Resulting in poor utilization of storage assets
 Configuration changes are very complex
SAN Volume Controller
 Hosts use virtual disks not managed disks
 Virtual disks consist of managed disks from
any device within the storage pools
 Unused capacity can be easily reallocated to
help dramatically improve capacity utilization
Use More Cost Effective Storage for Disaster Recovery
SANs Today
 Copy services vary across storage subsystems
 Storage array services are limited to within the
box or to a similar box at the target
 Less expensive storage arrays either have
primitive functions or none
 Host based services consume valuable host
processing power and are constrained, complex
SAN Volume Controller
 Provides a Common Platform for Remote
Copy and FlashCopy across all SAN storage
 Consistent level of services and single point
of control for all copy services
 Target data can be stored on more cost
effective disk storage

 Large Hadron Collider
 CERN open lab: Massive datamanagement system built on
Grid Computing
Business Problem
 Unprecedented amounts of data
 Ability to manage and get to their data
wherever it may be and regardless of
which operating system created it
Solution Approach
 Provide a single file namespace
 Provide scalable and highly available
IT Environment
management of data
 Intel servers cluster with 28 TB
 Support high reliability (policy based
of disk storage
storage mgmt)
 Generating 5 petabytes (5
million gigabytes) of data a year  Lower Cost of Ownership
once they are up and running
Better Management of Files on a SAN
SANs Today
SAN File System
 Capacity is configured in LUNs
 Pooled capacity in a SAN wide file system
 Manual process for allocation and
differentiation of class of service
 Policy based rules for automated allocation
into storage pools
 File systems format and manage capacity per
application server
 Transparent addition or removal of storage and
resizing of the SAN File System
 Over-allocation schemes require application
specific solutions
 Pooled storage with quota management does
not require application specific solution
