HP StorageWorks Storage Mirroring Recover Scripting Guide (T5437-96022, November 2010)

TargetPaused
Description—Internal setting that indicates if the target machine is
paused. Do not modify this setting.
TargetPausedVirtual
Description—Internal setting that indicates which target machines are
paused. Do not modify this setting.
TCPBufferSize
Description—Size of the TCP/IP buffer in bytes.
Values—4096-7500000
Default—375000
GUI Setting—None
Service restart required—Yes
Notes—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. Use the following recommended settings to improve Storage
Mirroring Recover throughput performance.
l 100Mbit LAN—The setting should be around 37500.
l 1Gbit LAN—The setting should be around 375000.
l WAN—The setting should be around 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
Description—Temporary directory used when replicating Windows 200x
encrypted files.
Values—Any valid path
Default—\Program Files\StorageWorks\Storage Mirroring\Temp
GUI Setting—None
