The NC523SFP is an eight lane (x8) PCI Express (PCIe) 10 Gigabit network solution offering superior bandwidth in a ProLiant Ethernet adapter. This dual port PCI Express Gen 2 adapter supports SFP+ (Small Form-factor Pluggable) connectors, requiring either Direct Attach Cable (DAC) for copper environments, or fiber transceivers and fiber cables for fiber optic environments. The NC523SFP ships with advanced server features that ProLiant customers have come to expect, such as support for TCP checksum and segmentation (LSO) offload capability, VLAN tagging, jumbo frames, IPv6, and more. Flexible to order and install, the NC523SFP can be used in either standard or low profile slots.
Works with generic DAC
This review is from: HP NC523SFP Fiber Optic Card
Pros: This NIC works with several brands of generic DAC, works with the default Linux and FreeBSD drivers.
Cons: Runs very hot - too hot to touch.
Other Thoughts: Each DAC has a vendor ID embedded in it. Many 10GBE NICs will only work with the same brand of DAC, but this card seems to work with any DAC. At least it works with 3 different brands of generic cables we have. I'd give it a 5th star but we only need 1 port per computer so the 2nd port is an expense and heat source we don't need.
