Originally, Qlogic was OEM for Sun, and we used them extensively.
Now, I am moving most of my stuff to Emulex. Just works well, and most
vendors don't have a problem supporting them (EMC, 3Par).
I have a NBU system now, using RHEL4 that has one Qlogic and one Emulex
in it, both attached to the same Scalar 1000 tape library. I didn't
really have any problems setting it up, and it has been running
flawlessly for the last two years.
