I've been using FreeNAS for the past year, and have run into an interesting application for FreeNAS. I'm looking to create a "mega store" for near-line backup. I have a Sun J4400 24 bay storage array with 21x 10K 4T drives, 3x 18GB, SSD's, and a Sun Fire X4140 Dual AMD Opteron 2384 Quad cores 2 x 2.75GHz with 64GB RAM. In that unit I have a single 128GB SSD and 5x 300GB SAS 15K drives.
I've configured the unit as follows:
FreeNAS 9.2.1.6 on 8GB pen drive
VOL01
20x 4TB SAS 10K disks RAIDZ - actually 2x10 4TB RAID groups as one volume
2x 18GB SSD LOG disks
1x 128GB SSD Cache disk
VOL02
5x 300GB SAS 15K disks RAIDZ
1x 18GB SSD LOG
1 spare 4TB SAS drive (Hot spare not possible with FreeNAS)
Any ideas on improvement? I only have about 3TB data on it now, and it seems to perform quite well, easily saturating the 4 onboard 1Gbit NICs. I do have a 4 port 10Gbit copper card, but no drivers for FreeNAS/FreeBSD exist for that NIC. I have ordered some Intel 10Gbit cards and will implement them when they arrive.
