The new Intel® Ethernet Server Adapter I350 family builds on Intel's history of excellence in Ethernet products. Intel continues its market leadership with this new generation of PCIe GbE network adapters. Built with the bridgeless Intel® Ethernet Controller I350, these adapters represent the next step in the Gigabit Ethernet (GbE) networking evolution for the enterprise and data center by introducing new levels of performance through industry-leading enhancements for both virtualized and iSCSI Unified Networking environments. This new family of adapters also includes new power management technologies such as Energy Efficient Ethernet (EEE) and DMA Coalescing (DMAC).
Pros: - Highly compatible - Stable - Good packaging - Standard and low profile mounting brackets - Lifetime warranty
Cons: I had to RMA the first one due to some unknown problem that popped up after two months and Intel honored the warranty and sent a new NIC.
Overall Review: Although it's a bit expensive for a NIC, I purchased this card for its compatibility. I have this installed in a pfSense firewall that runs FreeBSD and this card had no issue from the start. The system booted up and recognized this NIC with no extra steps necessary.
