Then they are one device. You can span multiples of these using CCD to get truly large devices. Satoshi was dooing a 1TB using 23G disks with a external subsystems; I don't know what the current status is (check the CCD home page for details). > This suggests that you could create a 128GB array out of conventional 4GB > disks, or a 736GB array out of the new Elite 23GB drives.. > > Or you could get yourself a RAID that appears as a single SCSI target and do > whatever the heck you want. Yes, that's the configuration that's meaningful. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
