I have an ESXi 6.0 HOST with several Windows and Ubuntu guest sitting in an ASUS essentio cm1630 (quad core AMD 3.2 and 16 gb's of DDR3 1 TB internal spinner used as my datastore). I want to attach my new QNAP TS-231 NAS with 1 3 TB Red WD in it for now but plan to expand. I want to be able to create a few ISCSI targets to my guests. The way I have it set up right now is I have 1 500 GB target and 1 TB target attached via SCSI initiators mounted on my windows 7 guest and Ubuntu 14 guest. Its working ok but I want to get some thoughts including speed, reliability and best practice. I don't have any data on the drives right now so I can scrap the whole plan and start from fresh if needed. The NAS has 2 NICS the PC only has 1. I do have a switch I just bought I could use if needed (TP-LINK TL-SG108 8-Port 10/100/1000Mbps). I plan to not raid anything since its only 2 bays and use crash plan as an offsite backup of the NAS. My goal is to familiarize myself with ESXi and VMware while running a small media server for my family. Any suggestions?
