Recommendation: Use vSphere Replication for this evaluation. While array replication has some
advantages over vSphere Replication, it is also more complex to install and configure and it
usually requires additional licensing from the array replication vendor. Using vSphere
Replication has a number of advantages including simple management using vSphere Web
Client, support for virtually any storage supported by vSphere including Virtual SAN, the ability
to configure replication on a per-VM basis, and vSphere Replication is included with vSphere
Essentials Plus Kit and higher editions. For a full comparison of array replication and vSphere
Replication, see SRM - Array Based Replication vs. vSphere Replication.
See “Configure Array Managers” in the Site Recovery Manager documentation for guidance
when working with array managers. Thoroughly read the documentation - release notes,
installation guide, etc. - that is typically included with a storage replication adapter. Most
storage replication adapters have specific requirements that are outlined in this documentation,
not in the Site Recovery Manager documentation.
After array managers have been successfully configured, paired, and enabled, information about
the array replication can be seen in the Site Recovery Manager user interface. This information
includes items such as the local and remote array names, local and remote devices, and the
direction in which replication is currently occurring.
Figure 10. Array Replication in the Site Recovery Manager User Interface
When using array replication, only virtual machines that will be protected by Site Recovery
Manager should be placed on a replicated LUN or volume. Combining protected and
unprotected virtual machines on the same replicated LUN or volume will produce warning
messages in Site Recovery Manager.
Review How Site Recovery Manager Computes Datastore Groups in the Site Recovery Manager
documentation to gain a thorough understanding of how datastore groups are composed when
array replication is utilized.
Exercise 5: Create a Protection Group
Before a protection group can be created, replication must be configured. If you have not
configured array replication or vSphere Replication for the virtual machines that Site Recovery
Manager will protect, you will need to do so before proceeding.
Details on deploying and configuring vSphere Replication can be found in the vSphere
Replication documentation.
