I am building a new NAS/SAN and have some questions
* = I need to purchase this
* 24 x 2TB 7200rpm 64MB drives
Areca Arc-1680ix-24 w/BBU and 2GB Cache
* Norco 4224 w/120MM Fans
Chelsio T3 10GbE Adapter
i7 930
MSI pro-e x58
12GB Ram
Future:
* SUPERMICRO MBD-X9SCM-F-O
* Intel Xeon E3-1230
* 8GB to 16GB of ECC RAM
I would like very fast sequential rates, and pretty good random I/O. I have a lot of media storage, and a VM farm for hosting applications/web servers, etc.
I am coming from an older platform very similar 'type' hardware: q6600, 8gb ram, areca arc-1261ml, 16x750gb in raid6, 10GbE and it performs okay, except for the long sequential jobs, i.e. taking 12+ hours to store 2.5TB of data. - I am also upgrading because I am out of space (selling off all the old hardware).
So now the questions:
Any recommendations for drives? I was thinking HITACHI 0F12115 Deskstar 7K3000 2TB 7200 RPM 64MB because they are reasonably fast and I can get them for ~$100 each.
With 24 drives which raid level is going to give me good data protection and good performance, I was thinking of doing a RAID 60 with 22 or 24 drives, depending on if I decide to have hot spares, or just a cold spare drive near by.
Is there any good way to start with 11-12 drives now, and easily migrate it to 22-24 drives later? I would think this question depends on which raid level is recommended.
