HP NC523SFP Fiber Optic Card

  • Email this page
ICON Loading...

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.

4 out of 5 eggsWorks with generic DAC

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.

3 out of 5 eggsMore compatible than most

Pros: This 10GBE converged adaptor worked with several brands of DAC, including PXE booting, which some other cards would not do. Drivers are included with recent FreeBSD (9.0) and Linux (RHEL 6) releases.

Cons: Runs too hot to touch, some of our systems would not boot with the card installed. Source code Linux drivers on the HP web site were specific to a tiny subset of particular (older) kernel versions.

Other Thoughts: We are using these for Ethernet LAN, not SAN.

We don't need 2 ports but the only single port cards we could find would not PXE boot with a 7 meter DAC.

10GBE is a snakepit of vague (in)compatibility claims.

Although described as a FO card, it has an SFP+ slot interface that works with FO or DAC.
