The following section is the basic design used at work for a number of Sun SPARC servers running Solaris 2.5.1 in an industrial development environment. It serves a number of database and cad applications in addition to the normal services such as mail.
Simplicity is emphasized here so /usr/lib has not been split
off from /usr.
This is the basic layout, planned for about 100 users.
   Drive:        SCSI 0                      SCSI 1
   Partition     Size (MB)   Mount point    Size (MB)   Mount point
     0           160         swap           160         swap
     1           100         /tmp           100         /var/tmp
     2           400         /usr
     3           100         /
     4            50         /var
     5
     6           remainder   /local0        remainder   /local1
Due to specific requirements at this place it is at times necessary to
have large partitions available on a short notice. Therefore drive 0 is
given as many tasks as feasible, leaving a large /local1
partition.
This setup has been in use for some time now and found satisfactorily.
For a more general and balanced system it would be better to swap /tmp
and /var/tmp and then move /var to drive 1.
