selected data, which can be a slower calculation. The mirror will remain in an
initializing state until the calculation is complete.

Compressing data
1. Make sure you have a valid source and target specified, click Configure
protection from the main Full-Server Failover Manager page, and then select the
Advanced tab.
2. Compression allows you to reduce the amount of bandwidth needed to transmit
data from the source to the target. The data is compressed before being transmitted
and then is uncompressed before it is written on the target. Typically, compression
is used in WAN environments, but not in LAN environments. If desired, enable
compression and select the level of compression that you want to use.
3. Click OK to save the settings.
Using firewalls with full-server workloads
If your source and target are on opposite sides of a firewall, you will need to configure
your hardware to accommodate full-server workload communications. You must have
the hardware already in place and know how to configure the hardware ports. If you do
not, see the reference manual for your hardware.
In a firewall environment, you must have a static mapping where a single, internal IP
address is always mapped in a one-to-one correlation to a single, external IP address.
Full-server workloads cannot handle dynamic mappings where a single, internal IP
address can be mapped to any one of a group of external IP addresses managed by the
router.
Full-server ports
By default, Storage Mirroring Recover uses port 6320 for all communications. To verify
or modify the ports, you must use the Replication Console.
1. Open the Replication Console.
2. Locate your servers in the server tree in the left pane of the Replication Console.
3. Right-click the server in the left pane of the Replication Console and select
Properties.
4. On the Network tab, verify or modify the Communications Port as needed. All
servers and clients in your full-server workload protection must be using the same
port.
