I am wanting to build NAS for my homelab that will store my ESXI VMs as well as a few TB of videos, music, random documents ect..
I spent the last 4 months researching, reading documentation, hardware guides, iSCSI vs NFS and I think I finally got a build together but I still have a few questions.
* CPU: Xeon E3-1230v5 3.4Ghz
* Ram: 4 x 16GB ECC Kingston Value RAM KVR21E15D8
* Motherboard: Supermicro X11SSL-CF-O
* Boot Drives: 2 x Samsung 850 Pro 256GB Mirrored
* SLOG: 2 x Samsung 850 Pro 256GB Mirrored (I know these do not have power loss protection but there doesn't seem to be anything that does within the same price range)
* Data Drives: 8 x 4TB Western Digital Red (Possibly adding 2 more for a total of 10 if it increases storage space significantly)
* PSU: SeaSonic X-850W
The motherboard has a LSI controller on it but I could not find any information on if it needs to be flashed and/or how to configure it as a HBA.
I am not really too sure if I should split up the drives into 2 different volumes, one for vms and one for all other data, or keep it all as one big volume. If I do go with multiple volumes what would be the best storage vs reliability raid for the non-vm volume.
I know that where ever the VMs end up living should be a mirror raid or possibly a striped mirror, using iSCSI with sync=always and a SSD backed SLOG. I know with iSCSI the recommendation is to not use more than 50% of the volume capacity, that is why I am thinking about having a vm specific volume to have as much space as possible for other data. I don't see my VMs using more than 5TB anytime soon and a lot of it will be duplicate data.
I have seen many posts asking about debupe and most of the time the response is "it uses a ton of memory so don't bother". I was not planing on using dedupe but I figured I would at least mention it. I find recommendations for at least 5GB ram per 1TB of dedupe so this build should have enough... but I am going to leave that answer to someone with more experience.
