I would appreciate feedback on best pool design for my new build. System will run FreeNAS, Plex, Sonarr, and Radarr (Download clients for Sonarr/Radarr arent on this box). I won’t be using this particular build for NFS, iSCSI, ESXi, ZoneMinder, etc. Data transfers will be almost exclusively by SMB or directly out of the box via Plex streams.
Fixed Specs:
Chassis: SuperMicro CSE-864
Motherboard: SuperMicro X9DRi-F
RAM: 16 x 8GB 1033mhz ECC (128GB total)
NIC: NC560SFP+ for 10Gbe and Intel i350 for 1Gbe
Hard Drives: Shucked WD white label 5400 rpm 10TB
Questions:
CPU: I have available matched pairs of E5-2680 v2 and E5-2697 v2. One set will go in this build, another goes in a separate machine for preparing and transcoding media. Which CPU do you advise for FreeNAS? I am inclined to put the “weaker” 2680’s in the NAS. I prefer to save the 2697’s for x265 re-encoding. Thoughts?
ZIL/SLOG/L2ARC: My research and experience says there would be no value from L2ARC or ZIL SLOG. Can someone please confirm?
vdev and pool design: I currently have a machine with 8 x 10TB in RAID 6 that needs to be migrated to the new FreeNAS build. I will then destroy that array and add the 8 drives to FreeNAS. Data to be migrated is ~34TB. I want to be able to expand over time to fill all 24 bays of the chassis and keep adding to external enclosures if the need arises. I will just keep adding identical vdev’s to the same pool as I need to increase capacity.
Possible vdev Architectures:
3x 10TB RAIDZ = 20TB usable, 6 drive minimum to complete migration, 160TB max chassis capacity
6x 10TB RAIDZ2 = 40TB usable, 6 drive minimum to complete migration, 160TB max chassis capacity
What are the recommendations? At full capacity, RAIDZ would result in 8 pools vs RAIDZ2 being four, thus double the IOPS. However, there is greater parity with RAIDZ2. More smaller vdevs or more parity? What is best practice here? Usable capacity is the same, but I can scale up more granular with only 3 drives vs 6 as I need to add space. I am inclined to select RAIDZ2 for safety, but I wanted feedback.
Thank you!
