Do you must mean the internal tests done for IBM's own system? The announcement
below was posted to this list by Stephen O'Neal under the thread: 15,200 users
attained on IBM's U2 UniVerse (which is a bit more than 2K..).
He or Tim may have more details.
Here's the original post:
This last weekend, we attained a new high number of users on a U2 database of
15,200 on a single system running an application!
Tim Snyder, Principle Consultant of the U2 Lab Services group, performed
this formal benchmark at one of the IBM benchmark centers on an
IBM p590
+ 64 dual core CPUs for a total of 128 processors
+ 124gb memory (no, that's not a typo - that's all the benchmark center
had available - odd number though)
+ 34 disk drives, striped with JFS2 on two FAStT controllers
It required an IBM p570 divided into 4 LPARs (logical partitions) to push
the load which simulated 30 different processes. It took 6 weeks of
preparation before the 3 weeks to set up the simulation at the benchmark
facility.
The application was from Pacific Decision Sciences Corporation
(www.pdsc.com).
The database had over 1 billion records in it.
Cheers

All,
IBM did a test on the volume of users
successfully supported on a U2 (UniVerse, I think) server. They pushed it
somewhere past 2K users without breaking things and only stopped when they
ran out of testing time.
I have a client who is
part SQL shop and part UniVerse. I'd love to get them a copy of this White
Paper so that I can help guide them to a better choice on an upcoming
project which could be implemented on either architecture. Showing the
robustness of the U2 system would go a long way.
Anyone have a link to the paper?
