2.
Enter your source and target servers. You can click
Browse
when selecting either server to locate it by drilling down
through your network. After you have specified a server name, enter login credentials when prompted. Once the server
is selected and logged in, the
Properties
tab at the bottom of Full-Server Failover Manager updates to display the
server’s properties.

You can configure optional protection settings, if desired. For details on each of the optional settings, see
Configuring

on page 7-3.
Warning
Memory
The target memory should be within 25% (plus or minus) of the source. If the target
has much less memory than the source, there will be performance impacts for the users
after failover.
CPU Count
There are no limits on the number or speed of the processors, but the target should
have at least the same number of processors as the source. If the target has fewer
processors or slower speeds than the source, there will be performance impacts for
the users after failover.
Capacity and
Free Space
The target must have enough space to store the data and a copy of the system state
from the source. This amount of disk space will depend on the applications and data
files you are protecting. The more data you are protecting, the more disk space you
will need.
NOTE:
The Full-Server Failover Manager cannot be run on Windows 2000 servers because certain actions that
are required during the recovery process are not supported by this operating system. You can recover
to and from Windows 2000 servers by running the Full-Server Failover Manager on Windows XP or
Windows 2003 servers.
NOTE:
If you select a source that already has Full-Server Failover enabled, the target and status of the protection
will populate automatically.
