entry that guarantees the desired number of concurrent I/Os. There are
two ways to add this registry setting:
•
Locate the mpi100io.reg data file (supplied with the driver files)
using Windows Explorer, double-click on the file name, and edit the
file.
•
Type this command at the command prompt:
regedit mpi100io.reg
This command inserts an entry in the registry to guarantee a
maximum of 100 concurrent I/Os per adapter.
If you want a different maximum number, you can edit the mpi100io.reg
data file; however, setting this value to a high number uses increasing
amounts of non-paged pool memory, a critical Windows resource. High
values for this setting can degrade system performance. Be sure to read
the information in the
mpi100io.reg data file before editing it. You must
reboot the system to activate the new registry setting.
To reset the guaranteed number of concurrent I/Os to the operating
system default of 32, follow the instructions above, but use
mpidefio.reg as the data file.
