I coupled this switch with a TP-Link TL-SG2224 Smart Switch and enable LAG/Active LACP. It allows my to have true Teaming and will support large packet sizes. I have four 802.3ad aggregate links on this switch...and it runs great.
I have been able to sustain 100% across all 4 ports for hours on end without a hickup or it getting too hot.
For a silly stress test, I was trying to max out the IO through my workstation (it has 4 SSDs in a RAID 0 config). I can simultaneously transfer files to/from my QS TS451, my 24TB Raid 60 server, my HTPC at full 1Ggig speeds, and another workstation ... while surfing the net and running my 10 HD camera network without any sort of lag/stuttering. I should note that my 24TB RAID 60 server has another one of these cards...the Qnap TS-451 has two ports capable of teaming.
Make sure to install this as an Intel(R) PRO/1000 PT Server Adapter...this will allow teaming & advanced NIC tuning (increase packet size, etc). If you install this as a 4 Port Intel NIC or NC364T, you will not be able to take advantage of the Advanced Teaming and other features of the intel chipset.
Did not seem to be (trivially) recognized by Windows 7 (tried it briefly before installing into the FreeNAS box) but that's not an issue for me. If it is for you, do some more investigating first.
It runs a little warm, but not super hot. The heatsink has lots of cross-ventilation to allow airflow both across the length of the board as well as up the face. Because I have other passively cooled cards in my case, I keep the case lying horizontally to improve convection. PCI cards in a vertical case, unfortunately, leave the heatsink on the *bottom* of the card which makes convection cooling impossible in that orientation. Standard PC cases don't generate enough forced-airflow across the heatsinks with just normal case fans. Obviously these cards are really intended to be in high-airflow 1U or 2U rack-mount chassis which have "tunnel fans" generating good front-to-rear airflow.
But as I said, this card is not super hot so it's not too much of an issue (although the SAS/SATA controller I have in an adjacent slot does run a lot hotter!)
Update 2017-09-06: Still pulling strong and zero maintenance; price has since dropped by 50%, so I'm buying another partly as a backup, but will also just slam into another box so that I can see how much I can push between the 2 machines :)
Other than that its a great card. I am using it in a Dell 780 SFF running PFSense as a home router. So far so good. I have fiber internet and I use the 4 port card to give each of my 2 access points their own Gig connection leaving 2 more ports for WAN and the remaining Gig port for a switch.
FreeBSD (PFSense) detected it without any problems and so far the throughput looks good with a few packages running.
Despite missing the half height card I still recommend this unless you really need one (I made it work without it). The card is genuine HP and mine was shipped and received fast.
This is the real-deal Server 4-port NIC. It will function as a multi-port teamed connection under Windows 7, but it is not a trivial install. You need to install the SERVER driversfrom HP (there is an online guide about how to get these installed on Windows 7, the default ones it "detects" are desktop drivers and do not allow teaming) and then run the HP management software to setup teaming.
You also need to configure your switch ports to be in LACP mode (NOT STATIC) to allow them to function or your whole network link will drop when you connect the second/subsequent NIC ports.
