Server Setting Description
TargetPausedVirtual
Internal setting that indicates which target machines are
paused. Do not modify this setting.
TCPBufferSize
Size of the TCP/IP buffer in bytes.
Values: 4096-7500000
Default: 375000
GUI Setting: None
The default setting creates a TCP window that will
accommodate most environments. In most environments,
this value will not need to be adjusted. However, if your
Storage Mirroring Recover network has a long end-to-end
route and the throughput is not where you would expect it
to be, then adjusting this parameter may have beneficial
results. This value is the bandwidth delay product, which
is calculated using the bandwidth of the network (in
bits/second) times the round trip time (in seconds)
between the two ends. Some recommended settings to
improve Storage Mirroring Recover throughput
performance are:
Gigabit LAN—The setting should be changed to 375000.
WAN—The setting should be adjusted to 130000.
While the calculations are fairly straight forward, the
values that have been suggested are not exact because
they depend on round trip time. Some improvements could
be gained by adjusting these values either higher or lower.
The value suited for your environment can best be
determined through trial and error testing.
TempDir
Temporary directory used when replicating Windows 200x
encrypted files.
