Hello everyone,
it has been a while since my last post on this forum, and I kindly need your help understanding a couple of things.
I'm planning to build a storage server (no VMs needed, just unRaid available on a 10G Network), probably starting with 10x 12TB hdd. I am a Pro license user, so correct me if I'm wrong, the limit is 30 disks for the array (actually, I would like to set 2 of them as parity disks), plus up to 24 as cache disks, right? The plan is to start with 10hdd + 2 parity disks + 2 m.2 cache disks, and fill in other drives when needed.
My second question is about bandwidth/pci lanes, a thing that I can not fully understand and calculate by myself:
To support the potential total of 32 disks (28+2 from the array, 2 of cache that I planned), I'll need HBA cards, but I also need bandwidth to run two M.2 ssds, and a 10G card. What I chose as processor is a Xeon E3-1275v6, and my motherboard of choice was a P10S-WS from Asus. The listed xeon can handle 16pci lanes, so will the described configuration work?
And last, again about bandwidth, how many HBA cards will I need to handle the 32 disks (Seagate IronWolf Pro 12TB and 960 evo 250GB)?
Thank you in advance,
Regards
