Managed raid array. I've used them, and all that is exposed to the system is a block level device. The specific one I used was a Fiber Channel device, but it had a SCSI equivalent. You had to telnet into the array to configure it. IIRC, it was a Sun T300. I know that it was a beta name, and got changed to T3 or something. The RAID cards that I am using now don't require any host OS driver. You configure it by hitting F3 during the boot process, and managing that way. However, there is no way to know if a particular disk is suffering degradation unless your host system has the proper driver. I forget the exact model number, but these are 3Ware SATA RAID cards. -john -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
