Storage Challenges
Information Management and Storage challenges are
impacting the ability to optimise information
value and deploy Information On Demand solutions

• Surge in criticality, value and volume of data is
  overwhelming
• Projected to grow at an annual rate of 64
  percent1

Explosive Data Growth

• Compliance with stringent regulatory requirements
  and audit procedures
• Estimated 20,000 compliance regulations worldwide

Compliance Requirements

• Lack of enterprise-wide storage strategy and
  disciplines
• Effective disk utilisation is lt50, with 20-40
  wasted space

Todays Realities
We are drowning in a sea of information. No one
knows the value, how long it should be kept, or
what the risk of keeping or getting rid of it
is. J.P. Morgan
For email so much of it is waste and so much
can be deleted. The idea of establishing whats
actually important is brilliant. Yes, ILM would
change my pain in that area. Warner Comm.
During 2002 the world created 5 exabytes of
information. An exabyte is the digital equivalent
of a trillion novels. The yearly total amounts to
somewhat more than all the words ever spoken by
human beings and it was up 68 from two years
earlier Forbes Data of Reckoning, May 10,
2004

Determine Policies to Manage Data
Determine appropriate business value and service
level of specific data, so that it can be placed
on the appropriate storage, and can be
subsequently moved to other storage or expired
(deleted) at a later date if the status changes
over the lifecycle of the information represented

Volume/Storage Management Issues
File/Data Management Issues

• Storage capacity is isolated in SAN islands
• Low capacity utilisation, difficult to pool
  volumes
• SAN islands require unique management
• Server downtime required to add/replace arrays,
  manage LUNs, migrate volumes
• Copy services are unique to each storage array

• File tasks must be done on each server
• Difficult to migrate applications to other
  servers
• Application Downtime required for FS changes
• No single view/access to files or data
• Cannot pool files based on Quality of Service

Increase the Return on IT Assets
Improve Manage Storage Service Delivery

• Traditional SAN
• Capacity is isolated in SAN islands
• Multiple management points
• Poor capacity utilisation
• Capacity purchased for and owned by individual
  processors

• With SAN Volume Controller (SVC)
• Combines capacity into a single pool
• Better utilisation of storage assets
• Single Management point
• Capacity purchases can be deferred until the
  physical capacity of the pool reaches a trigger
