I think I may have to put together a new server. For home use. Here is what I’m thinking of getting: SUPERMICRO MBD-H8SGL-O ATX Server Motherboard : $224.99 AMD Opteron 6128 Magny-Cours 2.0GHz 8 x 512KB L2 Cache 12MB L3 Cache Socket G34 115W 8-Core Server : $259.99 Kingston 8GB 240-Pin DDR3 SDRAM ECC Registered DDR3 1600 Server Memory : 4 x $59.99 = $239.96 PC Power and Cooling Silencer MK III 600W

Hence: $ cd /storage/bonnie/ [dan@kraken:/storage/bonnie] $ ls -l total 0 [dan@kraken:/storage/bonnie] $ bonnie++ Writing a byte at a time…done Writing intelligently…done Rewriting…done Reading a byte at a

After running the 3Ware diagnostic script, the status of the array went to OK. A short time later, it reverted to this $ sudo /usr/local/sbin/tw_cli info c0 u0 Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ———————————————————————— u0 RAID-0 OK – – – 64K 195.548 u0-0 UNKNOWN UNKNOWN – – p0 – 104.314 u0/v0 Volume – – – – – 195.548 But this differs from the web output (image) which is rather similar
