Thanks to the following for the fast reaction:

- Niels Roetert [Niels.Roetert_at_pqr.nl]
- Thomas kachelhoffer [kachelho_at_ccimap.in2p3.fr]
- Nikola Milutinovic [Nikola.Milutinovic_at_ev.co.yu]

        My original question was:
                        Please give me some advice.

                        I'm in the process of installing a new AlphaServer.
Usually there is a paper included with the advised partition size for the
root, usr and swap spaces based on the configuration. This time nothing was
included and I can't find an old paper for reference.

                        Does anybody know of an easy way to calculate these
numbers or advise me?

                        I need the numbers for the following configuration:
                        - AlphaServer DS20
                        - 3Gb internal memory
                        - 2 x 17Gb RAID 5 disks
                        - Tru64 Unix V4.0f
                        - Server will be an application and database server
                        
        All the answers where almost the same and not depending on
configuration, except for the swap space. I will summarize them:

- /: minimum 64k, recommended 128K or more
- /usr: minimum of 500Mb, recommended 1Gb
- swap: 2 or 3 times memory

Based on the tips I decided to change my configuration. Instead of 2x17Gb
RAID I made one mirrored system disk of 9Gb (2x9Gb disk RAID0) and make one
RAID5 set of the remaining disks. On the system disk I will place a swap
partition of 6Gb.
