So I'm inching closer to my first TrueNas build. And just wanted to have an idea of baseline performance and bottlenecks I should expect.
SuperStorage 6028R-E1CR12L
Dual Xeon E5-2603v3 1.6Ghz
LSI / Broadcom 3008 IT
64Gb RAM
12x 18TB WD SAS
Intel 10GbE
The unit is for video editing, so 98% if it's purpose is reads to edit bays.
It seems highly suggested to use mirrored vdevs, so I wanted to test that out, as well as a 6x RaidZ2. And then test some form of caching options just out of morbid curiosity, although most ZFS people I know are telling me not to bother. This community appears to be very polar when it comes to configurations and opinions.
Last night I seated the drives, everything is working fine, built out the pool, mirrored vdevs, setup the datastore, configured the networking, and ran read write tests, which planes out at about 630 Mb/s Write and 670 Mb/s read. Not horrible, but slower than I expected. I see higher reads on a shelf bought synology out of the box with 12x drives. Now I haven't tested simultaneous reads. If it can hold higher speeds across multiple clients, then overall high speed is less critical vs sustained reads on 3-4 edit bays. But I don't currently have a way to test across multiple devices.
Problem 1: Slow CPU?
Problem 2: Older HBA?
Problem 3: Tuning TrueNas for better performance?
What is an ample expectation for a 12x server running TrueNAS/ZFS? no frills, out of the box basic deployment?
