SVM zero-impact backups create compressed files so that operations resume after an unexpected event quickly and non-disruptive to normal operations.

SVM servers coordinate backup operations so that applications experience only a few seconds of interruption during normal backup procedures.

multiView snapshots as part of a backup solution maximize uptime by reducing RPO and RTO of key business applications.

SVM zero-impact backups improve business continuity by enabling rapid resumption of operations after unexpected events.

SVM zero-impact backups eliminate the backup window, so backups can occur at any time while applications remain online.

The ability to retire equipment before going off warranty and onto maintenance.

The ability to extend the useful life of an asset by repurposing it to a different use.

The ability to non-disruptively refresh the storage infrastructure as business requires.

The ability to pool storage by common storage systems.

The ability to snapshot entire applications space efficiently.

SVM mirrors will eliminate tape from the customer's environment.

SVM asynchronous mirrors will reduce communications costs between the primary and DR sites.

SVM will allow the customer to target different disk tiers between the two sites.

SVM asynchronous mirrors are great sources for remote backups.

Administrators can assign applications to different storage pools based on tiers of storage resulting in a lower total cost of ownership.

Administrators can assign storage to different hosts to increase storage utilization in the data center to lower total cost of ownership.

Administrators can mirror storage to different locations to ensure disaster recovery is implemented resulting in a lower total cost of ownership.

Administrators can implement server virtualization methods and tiered storage which aligns with virtualized servers resulting in a lower total cost of ownership.

A thin volume serves up only the data blocks called for by a read or write request.

A thin volume automatically provisions additional capacity for large I/O read requests.

A thin volume holds only the changes (writes) made by hosts to the thin volume.

A thin volume migrates data from an existing LUN into a new pool.

The SVM server processes control frames.

The SVM server processes data frames.

The SVM server manages metadata.

The SVM server translates addresses.

The SVM server moves data.

increased utilization

snapshot enhanced mirroring

extended useful life

striping LUNs across arrays

Use the multi-pathing architecture to zone the host dedicated to the Tier 1 storage and zone a separate host dedicated to Tier 3.

Non-disruptively promote the volumes from the Tier 3 storage to the Tier 1 storage before the changeover and demote the volumes back to Tier

3 when the changeover is complete.

Define data policies which will automatically migrate data to Tier 1 and Tier 3 storage levels providing instant tiering.

Non-disruptively place all of the 15000 RPM drives in one array and all of the 7200 RPM drives in another array thus automatically tiering your storage to different workloads.

Sync mirror is good for all applications.

Sync mirror works well in a campus or MAN environment.

Sync mirror requires no manual intervention for failover.

Sync mirror always requires manual intervention for failover.

file deletion

site failure
