I have i7-2600K "server", recently I hit SATA hardware bug (some of SATA can eventually die on motherboards of old revisions). I put LSI controller to overcome this, but I think to replace the entire machine.
I'm aiming to Supermicro X8xxxx MOBO with dual E56xx, they are very cheap, but have everything in term of virtualization. Should I go for 1U or 2U ? Now I have 4x4TB 3.5 disks in RaidZ1 (please, don't insist to use 1+0, I have my reasons) and 2 mirrored SSD for root and caching. 1U for 3.5 disks means 4 disks, leaving my cache devices out of scope (well, I can glue them in empty space for PCI device, but this is mean). I can use PCIe NVME card, but X8 can't boot from it. How good is USB 2.0 for root? I think if will be very slow to boot, but what then ? Probably, they will die fast, but I can put 2 of them. Most X8 motherboards I saw have 2 vertical aligned USB 2.0 slots, I suppose for that reason.
2U server means 8 to 12 3.5 HDDs, more room and, I believe, lower noise but cost is higher for the same speed.
BTW, I even saw something exotic like blade chassis with 4x2 Xeons in 2U form!
What do you suggest?
Thanks.
