Need advice on All-Flash TrueNas/FreeNas setup and Dell PowerEdge R740XD or Supermicro SuperServer A+ SERVER 2113S-WN24RT

Hi I’m setting up a new NAS for production and I require an all-flash pool this is for a 12 to 14 TB space visualization studio working with 3d data and application like 3ds max blender Maya with 50+artist

Currently, we have this server with free nas
Server ConfigurationIntel
Xeon E5-2620 V3 @2.40GHz32Gb ram2x Intel I350-T4 Quad 1G Ethernet Server Adapter in LACP
OS FreeNAS 9.3 in 2x 120gb SSD Raid1

When setting up something like this, I’d check with ixsystems and see what it will cost. There are ways to save money, but I don’t think you’ll save a large amount over what they can sell you.

After that, I default to SuperMicro devices as my first choice. I would use dual processors. I’ve had some bad luck with Micro in the past, I’d go Samsung or Crucial drives first and 240GB for the OS is more than plenty.

With the number of users you have, I’d go for more drives that are smaller. In the spinning drive world of yesterday, more spindles=faster access. Use groups of 8 drives in raidz or raidz2, then a simple stripe between the groups of eight.

I would check your options with iXsystems .
