Hi,
in my current setup I use 2 SAS boards: a reflashed IBM 1015 as SAS controller and a 24 ports HP SAS expander.
Which motherboard do you suggest that could support this expander (has a SAS controller built in) and has those features:
IPMI
ECC
Xeon E31231 V3 support
VT-x and VT-D well implemented
2 10/100/1000 LAN with virtual machine offload engine
1 PCi-e 3.0 slot
Different x8 x4 slots.
