HBA Queue Depth

Hi,

we use B200 M2 blades with M81KR on 2.02r, running Exchange 2010 on ESXi 5.0 with PowerPath /VE 5.7, the UCS is attached via MDS to a VMAX.

EMC Best Practise for EX2k10 is to use PowePath and set the HBA queue depth to 128.

How?

I picked the "FC Adaptor Policy VMware" for the service profiles with the default values (64, 64, 512). Should I change anything here?

Any other idea what to change where? I am just performance concerned.

Thanks!

HBA Queue Depth

Hello Robert,

The LUN Queue depth parameter is hardcoded in the driver and is not exposed via FC adapter policy.

For Windows, it is 255.

For Windows, you can use the " FC Adapter Policy Windows " as baseline reference as it has default recommended values.
