Summering: Took awhile to get the "igb" driver installed on Linux ( CentOS 7 ) but I found this after the fact. http://www.intel.com/support/network/adapter/pro100/sb/CS-032498.htm This would have saved me more time, but I learned more about Linux drivers in the process.
Fördelar: Fully compatible VMware ESXi 5.5 Update 1 (OEM release). Out of the box support so you don't have to be build your own custom ESXi image with the drivers. It's a very fast and stable NIC chipset.
Nackdelar: Be advised, the card has only 1 Wake-On-Lan Port. Wasn't a problem for me, but just caught me by surprise more than anything.
Summering: We are using this card on one of our Dell C1100 servers along with the dual onboard controllers. We have networks for data and storage running at 1gbit. We have connected this card to the two networks with VLANs on the data and it is working perfectly. It definitely works with vmware ESXi 5.X.
Summering: keep in mind that this is a server-class device. At $75/port it's not for the average consumer who probably expects to pay $19 for a single port add-on nic. It does a great job; I have these and the two-port version (I350T2) in all my servers.
Summering: Bought a pair of these for a pair of systems to give me more physical network ports. For at home. Way overkill (in terms of cost) for the average Amazon shopper, let alone the average IT person. But, this exactly what I needed. Not much of a review, but, it's a quad port NIC card.
Summering: I have several of these running in my servers. The main reason is the support for SR-IOV, which basically allows Virtual Machines to access the adapter directly, thus eliminating a LOT of overhead. These adapters run very cool and are energy efficient.
