ConfigScale ConfigScale sets the memory footprint profile in
accord with the anticipated use case on a per
port basis. While the default value is 4, a value of
1 is considered to be the typical use case. The
ConfigScale parameter supersedes the
ExtTransferSize parameter for OneConnect
adapters.
For OneConnect adapters:
For all values except 0, up to 1024 targets can be
discovered and mapped. When ConfigScale= 0,
only 128 targets can be discovered and mapped. A
value of 0 limits max XRIs to 512.
Note: Use ConfigScale = 0 to minimize the
driver's per-port memory foot print.
When ConfigScale value is:
• 0 – the max transfer size is limited to 500 KB.
• 1 – the max transfer size is limited to 1012 KB.
• 2 – the max transfer size is limited to 2036KB.

Use ConfigScale = 2 if connecting to tape
devices.
• 3 – the max transfer size is limited to 2036KB,
which is the best setting if you are running
performance benchmarks in a
non-production environment.
• 4 – the max transfer size is limited to 512KB.
Emulex 16 Gb/s adapters:
ConfigScale is always set at 4. The max transfer
size is set according to the value of the
‘ExtTransferSize’ parameter.
Values: 0, 1, 2, 3, and 4
Default = 4
Note: For Emulex 16Gb/s adapters only the value
of 4 is valid.

DiscoveryDelay=n DiscoveryDelay controls whether the driver waits
for ‘n’ seconds to start port discovery after link
up.
If set to 0 = immediate discovery after link up.
If set to 1 or 2 = the number of seconds to wait
after link-up before starting port discovery.
Value: 0–2 seconds (decimal)
Default = 0. Dynamic
