I know this is for DEC unix, but I think it's the same principle for the pmax hardware. http://www.cs.arizona.edu/computer.help/policy/DIGITAL_unix/AA-PQT0C-TET1_ht ml/TOC.html Seems you can use it purely as a cache between the OS and the disk drivers. So this could be used for purposes other than NFS? Collin Baillie --
