I need a SAN for my home lab so that I can run lots of virtual machines (30ish currently) and have failover, etc. I tried backing them into a traditional NAS (linux machine with local 7200 rpm drives) over 1gig network and the virtual machines were very slow despite having 2 hyperv machines with 32 cores (64 logicals) and 192gigs of ram each. I did some research and found that the bottleneck was the NAS and the networking to that NAS. So, I've upgraded all of the servers to these 10gbe 'converged' cards (so I can have HBA and RDMA) https://www.amazon.com/gp/product/B01HMGWOU8/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 I also upgraded the switch to this 10gbe switch https://www.amazon.com/gp/product/B0787TKSQ9/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1 I however need to add a SAN and that is where I am struggling. Should I just get a vanilla tower or 2u and get some sort of SAS 12gb/s hardware raid care to connect all the drives via? Should I try and put a ZFS set of disks together? Any advice on the SAN side would be greatly appreciated.
