Subject: SUMMARY - AlphaServer 2100 4/233 info
Firstly I'll correct the machine type, it should have read an AlphaServer
2100 4/233, sorry about that.
My original query was :
> We are currently thinking of purchasing an AlphaServer 2000 4/233

> server. What would be useful (to clear any doubts about performance,

***************** Replies ******************
I had two replies one of which was more of a query, the second did give
some valuable info.
It'll support approx. 300 interactive dumb terminal users. The only
bottleneck experienced was the network (X.25 in this case).
There was a resounding yes for using RAID and disk stripping.
Finally there was a problem experienced with allocating a large numbers of
small files effectively and efficiently on adfs but no solution alas.

Any more info would be very much appreciated. Especially from those
using X windows in an academic environment.
Thanks again,
