and system state of the source. Since the virtual recovery appliance maintains its
own identity, it can be reused for additional failovers.)
l
The virtual recovery appliance can be any of the operating systems listed in
the
General source and target server requirements
l
The virtual recovery appliance must have the same or newer operating
system than the source (not including service pack level).
l
The virtual recovery appliance must have Storage Mirroring Recover
installed and licensed on it.
l
WAN support—If your source and virtual recovery appliance are across a WAN
and you want Storage Mirroring Recover to automatically update networking on the
guest operating system during failover, the following limitations apply. If you
choose not to have Storage Mirroring Recover automatically update networking on
the guest operating system during failover, you will have to update the network
manually, but the following limitations will not apply.
l
Windows Management Instrumentation (WMI)—The host and guest
operating systems must have the WMI service enabled.
l
User Access Control (UAC)—UAC must be disabled on the guest
operating system.
l
Name resolution—You must establish name resolution for the guest
operating system.
l
Domain controllers—If your source is a domain controller, it will start in a non-
authoritative restore mode after failover. This means that if the source was
communicating with other domain controllers before failover, it will require one of
those domain controllers to be reachable after failover so it can request updates. If
this communication is not available, the domain controller will not function after
failover. If the source is the only domain controller, this is not an issue.
l
Microsoft .NET Framework—The target server requires the Microsoft .NET
Framework version 3.5 Service Pack 1. This version is not included in the .NET
version 4.0 release. Therefore, even if you have .NET version 4.0 installed, you
will also need version 3.5.1. You can install this version from the Storage Mirroring
Recover CD, via a web connection during the Storage Mirroring Recover
installation, or from a copy you have obtained manually from the
