Was that a SCSI RAID ? I have battled with RAID5, hoping it would speed up /home access, but with a limited budget and no UPS the rebuild times were too long. I have run into (what I think is) disk bandwidth problems with a mere 40 clients - let alone your 200. One 100BaseT cable should comfortably take care of maximum transfer rates from even a RAID5 array, no ? Or is there sufficient cacheing on the NFS server to warrant extra network bandwidth ? Classroom sizes in South Africa can run to 40 or 50, and I am trying to get an understanding of a good NFS server setup with twin Application servers, and your network setup intrigued me.
