Disk I/O shouldn't be a problem, all disks we are planning on using are either FC (we have 2x36GB drives) or SCSI320 (we have like a box of them) and we want to use a Sun Blade 1000 (2x900MHz uSPARCs with dual PCI buses and FC controller). I think I'll tell my roommate that we need it all on one system and just get an Ext. cage for the SCSI drives. I want to avoid using NFS because of bandwidth. We have 5 people living here all with Interweb addictions ...
