At work we went to a "low-cost" solution: instead of a bunch of EMC Symmetrices and several high-end HP or Sun servers we use cheap Dell 2950s and Powervault disk trays. 1 2950 with 2 disk trays x 26 disks in 2 RAID 10 LUNs x ~1400 servers = ~36400 disks. We have 4 or 5 drive failures per day. The hardware guys run around like those guys who try to keep plates spinning on sticks. -- Christian http://photography.skofteland.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
