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
