Supermicro AOC-S40G-iQ2 Review: A Low-Power 40GbE NIC

Final Thoughts




The phrase most often used when speaking of Intel's new XL710 network controller is: game changer. We have to agree. The reduced power consumption and higher throughput performance increase server density.


Paired with Intel's new Haswell Xeon processors that double Sandy/Ivy Bridge performance, and Intel's DC P3700 NVMe storage, datacenters are now able to reduce the number of servers used to meet current workloads at a two to one ratio. This assumes datacenters move from E5 2690 to E5 2699 V3 systems. The Capex investment is recovered through Opex in the form of reduced power consumption and rack space. Another solution is to simply grow the datacenter.


Outside of the traditional datacenter, businesses with a large group of servers can also benefit from the new Supermicro XL710 controlled 40GbE NIC. Again, this is paired with the latest generation of hardware from Intel, such as processors with an increased core count and faster storage technologies. Businesses can reduce the number of servers with virtualized systems (one of the key benefits of the Supermicro AOC-S40G-iQ2), and reduce operating costs associated with cooling and system power.


At the time of writing, we weren't able to find the AOC-S40G-iQ2 in the channel in America, but that should change soon. Supermicro doesn't have an official product page for the part yet either, but we did find a reference to the NIC on one of the new X10 servers as an optional component. When available, we'll update this review with a product page and pricing.

The Bottom Line: Supermicro's AOC-S40G-iQ2 network card reduces the opex cost of 40GbE connectivity, and ushers in new technologies that increase virtualization.
