HP StorageWorks Storage Mirroring evaluation guide (T2558-96075, February 2008)

6 - 2
Establishing a connection
1. The Full-Server Failover Manager can be started from within the Management Console or from the Windows desktop.
 From the Management Console, select Tools, Full-Server Failover Manager.
 From the Windows desktop, select Start, Programs, Storage Mirroring, Full-Server Failover Manager.
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.
3. There are optional protection settings which are not necessary for this evaluation. Feel free to review the optional
settings, if desired. A complete description of each setting can be found in the User’s Guide.
Error Volume There are no limits to the number of logical volumes, although you are bound by
operating system limits. The target must have the same number of logical volumes as
the source. The target must have the same drive letters as the source. For example, if
the source has drives C: and D:, the target cannot have drives D: and E:. In this case,
the target must also have drives C: and D:.
Network
Adapters
You must map at least one NIC from the source to one NIC on the target. If the
source has more NICs than the target, some of the source NICs will not be mapped
to the target. Therefore, the IP addresses associated with those NICs will not be
available after failover, unless you configure the advanced options. If there are more
NICs on the target than the source, the additional NICs will still be available after
failover.
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.
