[delete comments regarding fitness of Sequent s/w and followups]

I really couldn't resist this one: 500 users on a dozen Suns =
500/12 Users per system =
41.67 users per system.

Let's call it 50 users per system to be fair :-)

Each SS400 = 22 MIPS   =>   0.44 MIPS/user
Say the Sequent had 30 processors rated at 5 MIPS each
i.e. 30*5  = 150 MIPS  =>   0.3  MIPS/user

So it look's like the dozen Suns would give you *more* power per user
than a single Sequent.

For the typical s/w dev. load a SPARCsystem 400 would eat this load
level for breakfast.

Heck there are people running over 100 users (happily) on a SPARCserver2.

Ok it varies with work load etc etc., but for more details contact
your nearest Sun sales office :-)

Needless to say these are my views not Sun's...
