Mac OS X Fibre Channel connectivity to the HP StorageWorks Enterprise Virtual Array storage system configuration guide (5697-0025, August 2009)

B EVA storage system software
HP offers array-based replication and local mirroring software for EVA storage systems. You can
make point-in-time copies, or snapshots, of your data for disaster recovery, testing, application
development, and reporting.
Two EVA storage system software solutions support Mac OS X:
• HP StorageWorks Continuous Access EVA
• HP StorageWorks Business Copy EVA
Using HP Continuous Access EVA with Mac OS X
HP Continuous Access EVA is a Fibre Channel storage controller-based data replication solution that
meets disaster-tolerance requirements and supports EVA storage systems.
Features include:
• In-order synchronous or asynchronous remote replication (remote mirroring)
• Automated failover support
• Normal and failsafe data protection modes of operation
• Dual-redundant controller operation for increased fault tolerance
• Intersite link suspend and resume operations
• Merge or write-history log in write order
Overview
Data replication is performed in the EVA controller and is transparent to the host, reducing the number
of host cycles required to perform data mirroring. Unlike a fabric-based or host-based solution, HP
Continuous Access EVA dedicates its resources to managing the replication process between arrays,
with minimal impact on applications, other data, and other devices in the SAN.
Figure 26 shows a sample configuration.
