I'm planning to buy a hardware intended as a proxy server - with 2 SCSI drives, 4 GB each (and 128MB of RAM) One of the drives would by my Linux OS and the other one my intended disk Squid Cache. What still do I need to add for a fault tolerant Squid filesystem? Would that be buying a third 4GB SCSI HDD and mirroring my 4GB Cache (i.e., the second SCSI HDD)? Joel
