Summary: I recently built out a two node Server 2012 v3.0 Hyper-V cluster and purchased two of these to support the multiple network needs of the setup. I teamed two of the ports and configured for Hyper-V virtualization. With this configuration I was able to enable VMq across the team and provide excellent speeds across my network. The other two ports are being used for iSCSI traffic and host OS traffic, both of which perform to a level I find pleasing.
Summary: I purchased one of these PCIe cards for a small server system to handle iSCSI over trunked links using LACP (802.3ad). It is running in Solaris 11 in an ESXi hypervisor system using direct pass-through. It is a fast and stable product and it has worked flawlessly for the last 8 months.
If you're looking for abundant virtualization connectivity, this is THE adapter to get!

Summary: The Intel I340-T4 is an amazing adapter for virtualization or multi-path connectivity needs. This adapter was paired with the Xeon E3 ThinkServer, and has exceeded my wildest expectations. While there is a newer model available (the i350), the cost savings for going with this unit are worthwhile. Upon installation of the adapter and hypervisor, I've put the unit through its paces in copying large patches to local data stores.
Summary: What can I say about this quad-nic as it just works. We needed it for a NVR that was capturing video from 62 3 Megapixel IP Cameras. Once we teamed the 4 NICS, we had absolutely zero performance issues. Not only a good value but an exceptional product!
Summary: Worked as expected. Using the NIC in a Dell R610 server that's loaded as a Checkpoint firewall. This specific NIC is the only NIC that's officially supported by checkpoint to use in an open license server to configure checkpoint's multi-queuing function.
Summary: Just works, zero problems. Auto-detected/installed by Windows 8, ESX 5.1, and LMDE. Under ESX I have 2 ports teamed and the other 2 setup as pass-through devices for VMs to use directly. PCI Express ver 2. Low power, specs say 4W.
