Our sys admins brought in a couple of t2000's to add to our database cluster - we pulled them out. Most operations take twice as long to run compared to our e2900. We tried adding some degree's of parallelism, but it really didn't help out. The t2000's have been turned into web servers.

Subject: RE: T2000 architecture reset on moderate-to-intense disk IO?

hey guys-

I tried to follow this thread some, but must have missed some other emails... could someone send some "details" to me off line? Would like to see/hear of the experience with the T2000... It offers some interesting opportunities in reduced footprint, less power requirements, and some increased processing power - but at the risk of losing some I/O bandwidth...

I guess I'm looking at this beyond the RAC discussion as mentioned below....
thanks in advance

Subject: RE: T2000 architecture reset on moderate-to-intense disk IO?           

        A new customer has an issue where their new T2000-based RAC cluster running Oracle clusterware (CRS) has a node go to reset under moderate to intense disk IO workload (10GR2, Solaris 10). The node that is being connected to drops to the OK prompt and that's it. There are no logs or messages in any logfile, CRS or otherwise.          

        Does anyone have any similar experiences?

....CRS reboots? Of course! Questions first. Is the customer using straight CRS or is it integrated with Sun Clusters or Veritas (yes 10gR2 will do that regardless of the "Marketing Machine" literature). To verify, do this:

$ ls -l /opt/ORCLcluster $CLUSTERDIR/lib/libskgxn2.so

With the answers to these questions, I can probably help you make some sense of it all.
