With any luck we should be getting a couple of Ivy Bridge-E based server motherboards in to test, along with Xeon processors.
> Haswell Xeons, these processors, destined for 2P systems, will take on the E5 26xx naming scheme with V2 on the end, with L designating low power versions.

The E7-8800 V2 chips would work in configurations that feature up to eight sockets and will feature 15 cores per CPU, along with Hyperthreading, resulting in 30 threads per socket.
They will also carry 30 MB of L3 cache and have quad-channel DDR3-1866 memory support, per socket.
