Need system with 180 users accessing 1 database

[Sam Kendall]

A friend of mine is part of a project which needs a computer or set of
networked computers to allow at first 140, and later 180, simultaneous
users to access and update a single database.  The system needs to be
fast, since the users will be updating the database as they talk on the
telephone; and it needs to be extremely reliable.  The database is
something like 300 Mbytes.

A UNIX system is desired, but any modern OS such as VMS is preferred to
the alternative, which is doing it on an IBM mainframe.

My friend is looking for recommendations on both hardware and database
software.  Recommendations are desired from vendors and from anyone with
experience doing something like this.

Please mail recommendations to me.  I will forward results to my friend
and summarize to the net.
