Pros: This is an awesome server card. I'm running it on a server 2008 R2 DC/file server and I can download from it at a sustained 90MB/s and not notice any network slowdown (in the form of DNS requests) from other stations. Also, the CPU usage is minimal when transferring data at those speeds.

Cons: A little pricey, but it's A) Intel and B) has the word "server" in its title. If you want fast, use the MB's built in port(s). If you want screaming fast, get this.

Overall Review: I'm going to get another one for the other server I'm running. I haven't been able to enable teaming on the card yet, but I'm going to tackle that soon and maybe I'll report back after :)

Pros: Installed without a hitch. Works great in (Open)Solaris. Setup of LCAP was as simple as enabling it on the switch and then using dladm to create an aggregate link. I suspect the setup would be just as easy on other platforms. Transfered a little over a TB so far, not a single hiccup.

Cons: Little pricy for a dual interface NIC.

Overall Review: Does include a half-height mounting bracket for low profile cases.

Pros: The Intel driver allows you to setup NIC teaming (802.3ad). It even allows for teaming with other adaptors with reduced functionality, e.g. no jumbo frames and no receive side scaling. I teamed it up with the Realtek 81xx that was on the motherboard in Dynamic Link Aggregation under windows 7.

Cons: A little pricy, but still the easiest way of getting more than 1Gbps network

Overall Review: Teaming may also be known as bonding or link aggregation (LACP). Make sure your switch supports 802.3ad.

Pros: Great Workstation Card. Does everything I need it too.

Cons: Price seems a bit high, but it's not for home use.

Overall Review: All my workstations use this card while my server uses the 4port version. It's very awesome and I love the speed when gathering large files from the server.

Pros: + Seamlessly works in ESXi 4.0 + Fast and Stable connections + Intel quality and peace of mind

Cons: None

Overall Review: We were using a couple of the Intel GT desktop PCI NiCs and had intermittent issues with ESXi 4.0. This card is flawless. Plugged it into an existing installation of ESXi 4.0, booted up and the ports were available in vSphere. Can't ask for more. Installed in a Gigabyte GA-MA790GP-DS4H.

Pros: Using for a DIY firewall, and the throughput is amazing. My Sophos XG installation immediately saw that it was an Intel NIC and loaded the drivers right up.

Cons: I wanted to order several more at a great price, but SERVERONICS is currently out of stock.

Overall Review: I purchased it here through SERVERONICS for what I see as a steal for $33. The card came with the low profile bracket already installed, but there was also a full height bracket included. Newegg listed the item as new, but I recieved New-Old stock as the bracket had the old Sun Microsystems logo stamped into the metal. It was inexpensive, and works extremely well.

Pros: Works great, no problems, does what its told. ESX 4.1 works great with this card, NOT SURE about ESXi as I don't use that version.

Cons: I'd complain about price but it is fast and does well so I won't.

Pros: Works well with hyperV/vmware esxi. Superior to onboard consumer grade NICs!!

Cons: None

Overall Review: Good nic - the price we pay for consumer grade onboard NICs.
