
System Memory—There are different memory requirements depending on the operating system
you are using. Be sure you have at least the minimum amount of memory for your environment.
You may want to consider having at least the recommended amount of system memory.

Disk Usage—The amount of disk space required for the Full-Server Failover program files is
approximately 70 MB. More importantly, you need to verify that you have enough disk space on
the target. See Finding a Compatible Target on page 4-1 for more details on selecting an
appropriate target server.

Server Name—Storage Mirroring includes Unicode file system support, but your server name
must still be in ASCII format. If you have the need to use a server’s fully-qualified domain name,
your server cannot start with a numeric character because that will be interpreted as an IP
address.

Protocols and Networking—TCP/IP with static IP addressing is required. By default, Storage
Mirroring is configured for IPv6 and IPv4 environments, but the Storage Mirroring service will
automatically check the server at service startup and modify the appropriate setting if the server
is only configured for IPv4.

Windows Management Instrumentation (WMI)—Storage Mirroring is dependent on the WMI
service. If you do not use this service in your environment, contact technical support.

Cluster support—Microsoft clusters identify disks by their disk signature, which is stored on the
physical disk in the master boot record. When Full-Server Failover is used to failover a cluster
node, the disk signature of the target will be different than the source and the cluster will fail to
start. Therefore, Full-Server Failover does not natively support the full-server protection of
Microsoft cluster nodes. However, you can alter the disk signature on the target manually. See
the Microsoft Knowledge Base article 280425 at http://support.microsoft.com/kb/280425 for
details on how to change the disk signature.
