I have two TrueNAS CORE systems. One is a production server and the other is a backup server. They are both Xeon/Supermicro/ECC/DOM systems. They both have very similar hardware and identical pools and vDevs. 6-16TB drives in Z2.
I don’t have enough storage to keep snapshots out as long as I want and I have decided to build a new backup server. Here is my plan right now.
I ordered this server from ebay.
Processor: 2x Xeon Gold 6130 2.10GHz 16C Skylake (total 32Cores)
Memory: 64GB DDR4 ECC REG
Hard Drives: None
Controller: 1x AOC-S3008L-L8e HBA 12Gb/s and AOM-SAS3-8i8E-LP Installed for external JBOD
NIC: * Integrated Dual LAN with 10GBase-T with Intel® X722 + X557
Secondary Chassis/ Motherboard specs:
Supermicro 4U 36x 3.5" Drive Bays
Server Chassis/ Case: SSG-6049P-E1CR36L
Motherboard: X11DPH-T
* Integrated IPMI 2.0 Management
Backplane: BPN-SAS3-826EL1-N4 12-port 2U SAS3 12Gbps single-expander backplane, support up to 8x 3.5-inch SAS3/SATA3 HDD/SSD and 4x NVMe/SAS3/SATA3 storage devices
BPN-SAS3-846EL1 24-port 4U SAS3 12Gbps single-expander backplane, support up to 24x 3.5-inch SAS3/SATA3 HDD/SSD
PCI-Expansions slots: 3 PCI-E 3.0 x16 slot 4 PCI-E 3.0 x8 slots
Slot 2 & 3 occupied by controller and JBOD Expansion Port
HD Caddies: 36x 3.5" Supermicro caddy (With rear 2qty 2.5" wired to onboard sata)
Power: Dual Power supply
Rail Kit: Supermicro Rev B Rail Kit 4U
I will order 2 SSD drives for a mirrored boot pool and update all the firmare on the ebay server.
I have 6 - 8TB drives that I pulled from an older pool that still test good. I have ordered 4 more 8TB drives.
I plan to move my backup server pool of 6-16TB Z2 into the new server, then build a new pool that is 10x8TB z2 I believe that those two pools will be the same size. I would then copy the old backup pool to the newly created pool.
Then, I would reformat the original backup pool and add 4 16TB for a new vDev that is 10x16TB Z2 and add that pool to the existing 10x8TB.
Any gotchas that I should be aware of?
Thanks.
