Looking for feedback on this build before pulling the trigger. I am currently running a decommissioned HP workstation for my home server with ESXi 6. The system has six WD Red Pro 6TB drives running in RAID6 with an Areca ARC 1880i RAID controller. The system has had a few random shutdowns recently but no hardware failures have been found when digging through the logs. I was sitting near the server when a recent shutdown occurred and things felt a bit hot. With overheating being my prime suspect, I have decided to move the storage out to a SAN while keeping the workstation running ESXi. This is a completely new undertaking to me, so mistakes are expected. The storage and RAID card will move over to the SAN so I only need a barebones system. CPU: AMD FX-6300 $97.50 RAM: Crucial Ballistix 16GB $84.99 MoBo: ASRock 970 Extreme3 $44.99 PSU: Rosewill Photon 750 $74.99 Case: Rosewill 4U $104.99 NIC: HP MELLANOX (2) $34.60 Cable: 10G Twinax 30AWG $9.50 SSD: PNY SSD7CS1131-120-RB $39.99 Total: $491.55 Intent is to expose the RAID6 array to ESXi on the workstation via iSCSI target. Haven't ever done that either, but seems pretty straightforward for both the setup of the target and consumption as acquisition in ESXi. SAN will run Ubuntu Server 16.04 along with RapidDisk to utilize unused RAM for disk caching. I've based the build off of this article from 2013 https://thehomeserverblog.com/esxi-storage/building-a-homemade-san-on-the-cheap-32tb-for-1500/ so that's why some components are older. Adding a few hundred dollars onto the build for more reliable components would be acceptable.
