We haven't checked the throughput on the QLA 1080 cards, and the Octane
systems that use them are legacy units for us -- so we don't really
care about throughput as long as the drives work.

We also have some QLA 12160 cards -- the end users think the
performance is better on those systems but no one has actually
measured them.

We have seen no problems with the QLA 12160 cards, as opposed to the
mixed results that we've had with the QLA 1080 cards.

A couple of suggestions for you:

1. Are you certain that your PCI card cage works?

2. If you unplug all devices from the QLA 1080, does it show up in
hinv?

Example:
