In the Host Configuration Guide, on page 59, it talks about setting the LUN queue depth on the Emulex HBA to 128.

The document also has a table that prescribes settings for a mixed storage environment. (in my case, XIO and VNX)

That table has no recommendation for LUN queue depth on the HBA module. It does talk about the per LUN SchedNumReqOutstanding parameter, which I would set to 256 for all XIO LUNS.

My question is, with a mixed storage environment, should I be adjusting the HBA LUN queue depth to the prescribed XIO settings or leaving them at the default (which I think in this case is 30)

Advice greatly appreciated

Thanks, Jim
