Figure 26 HP Continuous Access EVA with Mac OS X

HP Continuous Access EVA copies data online and in real time to a remote EVA via synchronous or

asynchronous replication through a local or extended SAN. Data replication can be bidirectional,

meaning that a storage system can be both a source and a destination. A LUN can be replicated

between two storage systems in one direction only. Write I/O is sent to the source, and then HP

Continuous Access EVA replicates the I/O to the destination.

A properly configured HP Continuous Access EVA environment is a complete, disaster-tolerant storage

solution that guarantees data integrity in the event of a storage system or site failure. For more

information, see the HP StorageWorks Continuous Access EVA Software website:

Using HP Business Copy EVA with Mac OS X

HP Business Copy EVA is the local replication component of the HP Enterprise Virtual Array.

Features include:

• The ability to create point-in-time copies called snapshots, snapclones, and mirrorclones of vdisks

• Adjustable snapshot, snapclone, and mirrorclone properties; such as redundancy (RAID) level,

read cache, and write protection

• The ability to present snapshots, snapclones, and mirrorclones as disks to hosts

• Immediate host I/O to snapshots and snapclones

• Instant restore of content of a vdisk using a snapshot, snapclone, or mirrorclone
