One big reason we're really looking into a SAN option is that we have a lot of unused disk space. A typical disk usage scheme for us is 6 GB for a clean Linux install, and 20 GB for a Windows install. Our disks are typically 80GB, and even after decent amounts of usage we're not even approaching half that. We install a lot of software in AFS, our networked file system, and users' home directories and project directories are in AFS as well. Local disk space is relegated to the OS and vendor software, servers that need it, and seldom-used scratch space. There might very well be a break-even point for us in terms of cost. One of the other things I was interested in was the "hidden costs" of a SAN. For instance, we'd probably have to invest in more UPS capacity to protect our data. Are there any other similar points that people don't initially consider regarding a SAN? Again, thanks for all your help. Peter
