Hello all,

This is my first time posting to this forum. I've read a lot here as well as other sites about building your own storage array and have a parts list I believe should do what I need, but I would love your criticism to make sure I'm getting what will work for me.

Need:
  • Large amount of storage
  • When data is moving, it can be thousands of 1 MB to 500 MB files.
  • Performance does not need to be blazing fast, but the faster the better (SATA speed is sufficient).
  • Money not too important

So this is the hardware I have picked out currently. Would you change any of it?
Supermicro SC847A-R1400LPB
X8DTH-6F Motherboard
Intel Xeon E5620 x2
96 GB Kingston DDR3 1333MHz 12 x 8 GB dimms
LSI 9211-8i x4
OS HD: Seagate 500 GB SATA-600 7200RPM 3.5in x2 mirrored
ZIL SSD: Intel X25-E SLC 64GB x2 mirrored
L2ARC SSD: Intel 520 series MLC 480GB
Data HD: Hitachi Ultrastar 7K3000 series SATA-600 3TB 64 MB Buffer x30

Using OpenIndiana and napp-it with ZFS, I was planning on having three 10x3TB in RAIDZ2.

Destroy away...
 
My thoughts (i am building something very similar, will post soon as well):

-Make sure the mem is ECC reg
-Make sure the drive is known to be supported by OI/Solaris
-Be aware that @3TB, if a drive dumps resilvering a new drive will lag

As for speed, if your pool will consist of one VDEV Raidz2 with 10 drives, your throughput/speed will be that of a single drive. If that is acceptable, i'd say leave as is. (you could also have multiple VDEVs, but if your using raidz2 (which i would reccomend if your using 3tb drives) that would eat alot of your usable space up.

Thats my .02, i am by no means a ZFS expert, but very interested in it myself as i am building up a dual node HA cluster myself using Nexenta.

Sweet build tho
 
First we have to ask...WHAT are you using this for? Also, how are you interfacing with it?

What you should need depends entirely on how it would be used and the workload you are running on it.
 
It will be mainly used to archive data we do analysis on. No VMs or anything like that. It will be an NFS server to our current linux cluster as well as a new blade center we are ordering. Most of the data will be stored there and left at rest. I've also thought about upgrading to 10 gig ethernet if that would help performance to the nodes.
