SVM's multiMigrate feature allows for non-disruptive data migration from one storage device to another, regardless of vendor.

SVM's multiMigrate feature allows for minimal disruption due to its use of low-impact snapshots to migrate existing data to new storage.

SVM's multiMigrate feature allows for non-disruptive data migration from one vendor's storage to another model from that vendor.

SVM's multiMigrate feature allows for new data to be written to the new storage until a regular maintenance window is available to migrate the

existing data.

SVM can reserve space for future use on a LUN-by-LUN basis.

SVM can build RAID structures for enhanced data protection.

SVM can migrate data from multiple storage arrays onto a single storage array.

SVM can make snapshots of volume groups that are spread across multiple storage arrays.

by keeping the servers from running out of space

by spreading the workload across controllers

by moving the workload to the DPMs

by sharing allocated but unused capacity across volumes sharing a pool

reclaiming trapped capacity

creating empty volumes to reserve capacity

expanding volume capacity automatically

making multiple copies of volumes for backups

saving money on overall storage costs

Using redirect-on-write and multiView, applications can be restored very quickly.

Using copy-on-write and multiView, applications can be restored very quickly.

Low capacity snapshots will reduce CAPEX by eliminating redundant copies.

Low capacity snapshots will reduce CAPEX by reducing hardware footprint.

Continue operations during infrastructure upgrades.

Introduce new storage devices quickly.

Eliminate storage previously reserved for backups and copies.

Reduce cost by utilizing high end storage only for high end data.

Reduce cost associated to application engineering.

by allocating capacity across RAID arrays

by striping volumes across RAID arrays

by mirroring volumes across RAID arrays

by provisioning additional servers

Async mirroring always uses FC verses IP for better performance.

Async mirroring can span long distances without performance loss.

Async mirroring was designed for server-to-server or disk-to-disk mirroring.

Based on the async mirroring standards, it is only good for distances in excess of 1000 (1600 km) miles.

Source and target devices need to be from the same vendor.

Servers are required to do the migration.

Downtime is required to do the migration.

The SAN fabric must support migration.

multiView will migrate the data online to another disk that can be used as a backup in the event of tape failure.

multiView will provide the means to consolidate the last evening backup with the current backup in the event of a tape failure.multiView will provide the means to consolidate the last evening? backup with the current backup in the event of a tape failure.

multiView takes PiT copies of database applications at user defined times. In the event of a tape failure, the backup can be redone off the same PiT image.

multiView will provide a full physical copy of the applications. In the event of a tape failure, the backup can be redone from the full physical copy.

multiView can be used to take a PiT copy. Additional PiTs can then be taken off the first PiT for test and development.

multiCopy can be used to copy the database to another storage array. multiView can then be used to take low capacity PiTs of the copy for test and development.

multiCopy will create a steady stream of data to a copy area. multiView can then be used to take PiTs whenever they are required for test and development.

MultiView can be set to only read the PiT data when the volume is not in use. Requests for PiTs for test and development can therefore be queued.

Add VMware ESX servers in front of SVM so that some servers could manage backup functions while others could continue to service I/O requests.

Use SVM to provision a server farm that allows the online catalog to be present in two locations: one for transactions and another for backups.

Use SVM multiView and a backup application, so they can do backups with no impact on production servers or on the LAN.

Add a second, less powerful storage array that SVM multiCopy constantly streams to as an online backup service.

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.

multiMirror will not corrupt data based on its internal ECC correction code.

Host-based mirroring uses IP which can be less reliable than FC.

multiMirror uses the reliability of the RAID devices to accomplish a much more reliable copy.

Snapshot-enabled mirroring allows multiMirror to retain several recovery points at the remote site for rollback purposes.
