Cluster workload protection requirements
● Standard cluster—If you will be protecting a standard cluster configuration, with a
shared SCSIdisk, there are two additional requirements.
● Network—The cluster's private network should be a unique subnet so that
Storage Mirroring Recover will not attempt to use an unreachable private
network.
● Volumes—The source and target should have identical drive mappings.
● GeoCluster—If you will be protecting a GeoCluster configuration, where data is
stored on volumes local to each node, there are several additional requirements.
● Operating system—The operating systems are limited to the Windows
Enterprise, Itanium, and Datacenter editions listed in the source and target
server requirements.
● Volumes—The source and target should have identical drive mappings.
● Hardware—Intel-based hardware is required. Microsoft support for MSCS
and MSCS-based Microsoft applications requires that the cluster
configuration appear on the Microsoft Hardware Compatibility List under
category Cluster.
● Cluster Network Name—Storage Mirroring Recover does not handle
dynamic changes to the cluster networknames, the names assigned to the
routes for network traffic. If a network name is changed for a network that is
used by a GeoCluster Replicated Disk resource, the resource must be taken
offline, the resource's network property must be changed, and then the
resource must be brought back online.
● Protocols and Networking—All of the networking requirements below must
be met.
● TCP/IP connection between nodes on the same logical IP subnet
● Your network can contain direct LAN connections or VLAN technology.
● The maximum round trip latency between nodes should be no more
than ½ second.
● Multiple networks are recommended to isolate public and private traffic.
