Hey all, so I'm building my first FreeNAS box as we speak. I'm aiming to build 1 zfs2 volume with encryption for personal home/media storage & streaming (with the plex media server pbi).
My question is this...
I'm hoping to use all 8 sata ports on my mobo each with a 4tb red drive giving me 32gb raw storage and ~21TB usable storage (I understand this is not an ideal # of drives but AFAIK thats only a real perf hit in enterprise production environments, please correct me if I'm wrong here). However, my mobo and cpu (SuperMicro X10SAT - http://www.newegg.com/Product/Product.aspx?Item=N82E16813182830 and Xeon E3-1220V3 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819116907) only support 32GB of RAM (which I plan on maxing out with ECC memory). While this is (barely) within the threshold of 1GB per TB raw storage in the pool, it does not leave the extra 1-2GB for FreeNAS or whatever might be needed by the Plex Media Server pbi.
So the question is, how badly does perf degrade if I'm a few GB shy of the recommended RAM? In my use-case (home use / media streaming) would I see enough of an impact to warrant using only 7 drives instead of 8 (which would still meet my storage needs for now, just wouldn't be ideal). Also does encryption add any requirements to RAM, or is that just more CPU load?
Thanks in advance
