Hi FreeNAS Gurus,
So far the largest FreeNAS I've built has been 10 TB RAID-Z2 on a quad-core AMD system. On all the systems I've been very impressed with features and reliability. Now it's time to double-down.
Looking to build 160 TB archiver with RAID-Z3. Here's what I'm thinking ... I'd appreciate any component-level advice, questions, discussion, etc.
Would really appreciate you guys' and gals' feedback on this one.
This will be an archival and slow-restore system, seeing about 50 TB of churn for only one quarter of the year (only reads for the remaining three quarters of the year).

- 2x Micron enterprise-class 100 GB SSD in hardware RAID-1 for FreeNAS install
- Tyan dual G34 socket server board with 1x Intel 82574L GbE, 2x Intel 82576EB GbE, quad-channel DDR3, onboard LSI RAID for the SSD mirror
- 2x 3ware 9750-24i4e SATA/SAS 6Gb/s PCIe 2.0 w/512 MB onboard memory controller card (FreeNAS built in monitoring? or CLI only?)
- 2x battery backup for above HBA
- 2x Opteron 6200 8-core (16 cores really necessary? how about 8 cores on a single CPU? or better to go with 2x 4-core? probably only use light ZFS compression)
- 256 GB ECC DDR3 SDRAM (256 GB really necessary? Maybe 128 GB instead? 192 GB? ... not doing dedupe)
- 45x Seagate 4 TB 5900-RPM SATA drives (model ST4000DM000), 64 MB cache SATA-6G... (cheap, low-power, low-noise, RAID-Z3 so who cares?)
- 1x spare drive above for 'warm spare' hoping true hot-spare daemon comes to FreeNAS someday
- Chenbro RM91250: 9RU, 50x 3.5" hot-swap SAS bay, 2x 3.5" hot-swap SATA bay, 12x SAS backplanes (8087), 1620W 3+1 redundant PSU
- Beefy UPS with 1-hour runtime
