Greetings fellow NASers,
I am looking to build a from scratch 30+TB NAS and have put together the following hardware list. I would greatly appreciate any feedback and/or questions, comments or concerns on this list. Warnings and "gotchas" are also welcomed. I hate getting sucker punched.
I realize the hardware is probably a bit overkill, please ignore that. What I'm looking for is a medium performance NAS that is STABLE, ie I really, really don't want to lose data. I currently have a 12TB RAID setup in a Ubuntu HTPC environment and it's pretty much dead. Was able to save most of the data but this is the second time it's crashed and I don't want to lose data again.
Purpose of NAS: To store media files (TV, Movies (HD) and Music) to be played via either a Boxee or my current HTPC.
Disks: 12 x HITACHI Deskstar 5K3000 HDS5C3020ALA632 (0F12117) 2TB SATA 6.0Gb/s 3.5" Internal
12 x WD 2TB Green Drives
Motherboard: MSI 890FXA-GD70 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard
CPU: AMD Athlon II X2 250 Regor 3.0GHz Socket AM3 65W Dual-Core Desktop Processor
RAM: G.SKILL Ripjaws Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
PSU: KINGWIN Lazer Platinum Series LZP-550 550W ATX 12V v2.2 / EPS 12V v2.91 / SSI EPS 12V v2.92 SLI Ready CrossFire Ready 80 ...
SAS Card x3: LSI MegaRAID Internal Low-Power SATA/SAS 9240-8i 6Gb/s PCI-Express 2.0 RAID Controller Card, Single
Case: NORCO RPC-4224 4U Rackmount Server Case with 24 Hot-Swappable SATA/SAS Drive Bays
*Questions I have: Will these LSI 9240 cards work with FreeNAS 8.x? Does anyone know if they will support 3TB drives?
Are these decent enough SAS cards to handle 24 drives? Will the PCI bus cause bottlenecking? Also, the RAM is Quad Channel but the Motherboard only supports Dual Channel RAM, with the RAM just run at Dual Channel or will it not be compatible at all?
I plan to boot FreeNAS off of CF from the IDE slot so all 24 drives will be dedicated to the NAS.
After doing some research and talking with friends, I am going to run 3 pools of 8 drives each to minimize rebuild times if there is a failure and to ensure that I can lose multiple disks without loss of data. The pools will be RAIDZ2 pools.
I've done a lot of reading on these forums but haven't really found this specific hardware setup and would really like to get some opinions/expertise before I start shelling out the cash.
Thanks in advance for everyone's help, it's greatly appreciated.
