VR38DETT thank you very much for your advice. I have 8 NICs in each server (diagram showing only 3), how would you recommend setting them up in two node cluster? Planning to have (moved from old 2008R2 cluster) 50-60 virtual servers (Windows 2003/2008/2008R2) on new 2012 Hyper-V cluster. About 7-10 VMs are very “important” SQL 2008 servers, the rest just need to be highly available. How about jumbo frames, some people recommend some don’t?! Should I divide 3TB LUN onto multiple CSVs or keep it as it is?
