15 - 29
StatsWriteInterval Interval, in minutes, in which statistics are written to the statistic.sts
file
Values: 0 - 65535
Default: 5
GUI Setting: Server Properties, Logging tab, Statistics, Write Interval
SystemMemory
Limit
Set by the Storage Mirroring service, each time it is started, to record the
amount of available memory.
TargetPaused Internal setting that indicates if the target machine is paused. Do not modify
this setting.
TargetPaused
Virtual
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 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 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.
GUI Setting:
C:\Program Files\StorageWorks\Storage
