We run a Convex C220 with 16 GB of disk. You will find that there is a
limit of 2GB on file systems (offsets are held as signed 32-bit ints).
We have had no problems with user partitions of 900Mb (single disk)
although you need a lot of tapes in your backup system. We do run a
1.8 MB partition for scratch files which gives no problems, but we
don't back it up. Most of our user files are stored in the 'g' and 'h'
partitions, since we can use smaller fragment sizes (512) provided the
file system is less than 512 Mb. Above this limit we must have 4096 byte
fragments.
