The Projected Impact on Storage

Environments

“But What If the Projections Are

Wrong?”

Oct 9 2001: IT Industry Shrinks by 16 PctA burst in the dotcom bubble and weakened investment in information technology have shrunk the IT market size by some 16 percent, an industry research firm reported yesterday.

According to Korea International Data Corp. (IDC), the market size of the domestic IT industry is estimated at around 13.5 trillion won this year, a 16.6 percent contraction from the previous year.

The decline is a sharp contrast with the firm's former projection, when it predicted a 10 percent growth in the 2001 market size of the IT industry last October.

storage virtualization

A technology that creates a logical view of storage distinct from its

physical components

storage virtualization

• create a pool of heterogeneous storage for an environment of heterogeneous servers

• enable dynamic creation, expansion and deletion of logical units

• increase utilization of storage resources

• drive down administration cost more than 10x

virtualization

• limited to that array’s disk

• cannot span multiple frames

• different from one model to another even with the same vendor

networkbased

virtualization

• virtualizes multiple arrays from different vendors

• capacity on demand• volume management:

• lun partitioning• lun expansion

• resource pooling• data replication

Pooling Storage

• improve disk utilization

• automated storage management also cuts down on human error

• disk expansion

• storage matched to the application

• tiered storage pool• criticality differences• performance level• Cost per MB

heterogeneous storage

consolidation

• manage disparate devices in a uniform way

• allocate unused storage capacity to servers or applications that require it

• provides capacity on demand

• centralized storage management with OpenView SAM as the enterprise manager

sample customer issue #1

customer has a large NT deployment running a variety of applications & has the followingissues:

• servers quantity became unmanageable• too much wasted space on internal disks• too many inefficiencies with tape drives

on every server

• Surestore SANlink features used:

• point-in-time copy

• virtualization

• security

• FCP mirroring

Solution: Consolidation• Surestore SANlink is leveraged to migrate data from internal disk to a centralized storage array

• Multiple smaller servers are consolidated onto single larger servers

• FCP mirroring and Point-in-Time Copy is used to create copies of the primary data for testing and backup and recovery

• A centralized backup and recovery solution can now be deployed to replace the unmanageable amounts of tape drives

• By virtualizing the storage array, the customer has to ability to dynamically allocate disk space

sample customer issue #2

• Surestore SANlink features used:

• point-in-time copy

• virtualization

• security

• FCP mirroring

• backups are taking longer than the time allotted (defined window)

• to complete backups would mean delaying online startup

• expanding the backup window would reduce online availability

• not completing backups causes a disaster recovery exposure

Solution:

• Surestore SANlink is used to create a virtualized pool of disk

• FCP Mirroring or Point-in-Time Copy creates an copy of the primary data volumes, which can now be mapped to a backup and recovery server

• the backups can now be completed without impacting LAN performance or application availability

• backup time is reduced to minutes instead of hours.
