Pros: Recognized by most O/S out of the box High-throughput WOL support Full and half PCIe form-factor 4-in-1 - convenient!

Cons: Expensive WOL only supported on Port 1

Overall Review: Wonderful product - see the pros and cons. I am using this for vSphere 5 (with Update 2) and it was recognized and installed immediately out-of-the-box
