Hi,
I am building a new FreeNAS and upgrading from 1Gb to 10Gb NIC. I mostly do 3D design work, rendering thousands of PNG files to the NAS, then re-importing those files into video editing software. Also photoshop, reading large 3D files, assorted production tasks.
My current build is X10SL7-F / E3-1230 v3 / 32GB - this will be used as a backup NAS after I build the new one. I'll also likely leave crashplan / plex / transmission running on this machine.
Considering this for new build
X10SL7-F
E3-1265L V3 (small chassis, potential thermal constraints)
32GB ECC
6 x 12TB WD Red Plus - RAID10 (~27TB) (quietest/coolest drives - studio apartment)
2 x SSD (jails / zil / L2ARC?)
Chelsio t520 -CR 10G SFP+ card
My question: With the RAID10 + 10G connection, can I significantly increase the performance of SMB by shelling out for an X11 board with 64GB of RAM and adding L2ARC or will I already be getting close to max single-user performance with the X10 setup?
Here's my current ARC performance, but perhaps Crashplan/Plex/Transmission heavily skew this data one way or another so if I don't run those services on the new server, I would guess it will look much different.
Thanks for any thoughts on this. My first instinct is to just build the X10 version and experiment with using a couple SSDs as an SLOG and a metadata-only L2ARC
