Table 1‑1. Heterogeneity of SRM Components Between Sites (Continued)
Component Heterogeneous or Identical Installations
Storage arrays for array-based replication Can be different on each site. You can use different
versions of the same type of storage array on each site, or
different types of storage array. The SRM Server instance
on each site requires the appropriate storage replication
adapter (SRA) for each type or version of storage array for
that site. Check SRA compatibility with all versions of
storage array to ensure compatibility.
SRM database Can be different on each site. You can use different
versions of the same type of database on each site, or
different types of database on each site.
Host operating system of the SRM Server installation Can be different on each site. You can run different
versions of the host operating system and the host
operating system can run in different locales on each site.
Host operating system of the vCenter Server installation Can be different on each site. You can run different
versions of the host operating system and the host
operating system can run in different locales on each site.
Example: Heterogenous Configurations on the Protected and Recovery Sites
The SRM and vCenter Server installations might be in different countries, with different setups.
n
Site A in Japan:
n
SRM Server runs on Windows Server 2008 in the Japanese locale
n
SRM extends a vCenter Server Appliance instance
n
SRM Server uses an SQL Server database
n
Site B in the United States:
n
SRM Server runs on Windows Server 2012 in the English locale
n
SRM extends a standard vCenter Server instance that runs on Windows Server 2008 in the English
locale
n
SRM Server uses an Oracle Server database
Using Array-Based Replication with SRM
When you use array-based replication, one or more storage arrays at the protected site replicate data to peer
arrays at the recovery site. With storage replication adapters (SRAs), you can integrate SRM with a wide
variety of arrays.
To use array-based replication with SRM, you must configure replication first before you can configure SRM
to use it.
If your storage array supports consistency groups, SRM is compatible with vSphere Storage DRS and
vSphere Storage vMotion. You can use Storage DRS and Storage vMotion to move virtual machine files
within a consistency group that SRM protects. If your storage array does not support consistency groups,
you cannot use Storage DRS and Storage vMotion in combination with SRM.
You can protect virtual machines that contain disks that use VMware Virtual Flash storage. Since the host to
which a virtual machine recovers might not be configured for Virtual Flash, SRM disables Virtual Flash on
disks when it starts the virtual machines on the recovery site. After the recovery, you can migrate the virtual
machine to a host with Virtual Flash storage and manually restore the original Virtual Flash setting on the
virtual machine.
