We are currently setting up the tpc-c benchmark on the cluster. Tpc-c is the standard benchmark for OnLine Transaction Processing ( http://www.tpc.org/tpcc/ ). We will be doing some test runs on the pureScale cluster and some tuning to see what kind of throughput we can get out of the cluster for typical OLTP workloads . We will start out with 4 nodes first with the default parameters, then start tuning and tweaking. Please let me know if you want to know more?
