I am using a dual core machine with 1GB ram just for the OS even though its not scratching the 50% usage My raid controller is 3ware 9550SX-12LP 64-bit/133MHz PCI-X with 256 MB DDR2 400 memory with ECC protection supporting all raid types and with RISC PowerPC cpu to provide real HW raid This host is handling more then 8TB in Raid1 and Raid5 units easy and you can leave hot spare drives and setup fast rebuild Notifications both in snmp and mail will provide you alerts once a unit is degraded or drive is giving errors (pre-fail) I do recomment using real 64-bit interface and well... this card is old, you can get newer and better similar cards.. so do the math Shana tova to all

I did some checking and calculated the costs, and figured out that if I want to have a decent 12TB solution NAS box, it would be best if I would roll my own. (12 TB before all the RAID stuff, after that it would lot less). All other solutions are very expensive (example: IBM EXP 3000 costs here 6K nis without a single hard disk). I'm planning to use hardware based RAID card, minimal Linux distribution and have some offers like iSCSI, NFS, CIFS - the usual suspects. My question is: since I'll use hardware RAID card, which processor and how much RAM should I put in such a machine? Xeon is overkill IIRC. What do you suggest?
