The Register reported a spat between HP and Oracle on the TPC-C benchmark. Per above, HP submitted a TPC-C result of 3,388,535 tpm-C for their ProLiant DL980 G7 (8 Xeon X7560 processors), with a cost of $0.63 per tpm-C. Oracle has refused permission to publish.
Late last year (2010) Oracle published a result of 30M tpm-C for a 108 processors (sockets) SPARC cluster ($30M complete system cost). Oracle is now comparing this to the HP Superdome result from 2007 of 4M tpm-C at $2.93 per tpm-C, calling the HP solution a clunker. The SPARC cluster is comprised of 27 nodes. Each node is 4 socket, 16-core (64 cores total) with 8 threads per core (512 logical processors total) and 512GB memory. The complete cluster is comprised of 1728 cores and 11,040 x 24GB SSD drives.
Microsoft wants system vendors to move the newer TPC-E benchmark. A ProLiant DL980 or any 8-way Xeon 7500 TPC-E results other system vendors would be good to see. Oracle has not published any TPC-E benchmark result. The rumor mill has it that Oracle on a single system runs TPC-E just fine. The problem is believed to be that Oracle RAC cannot scale on TPC-E to degree desired by marketing (even if it is ok by technical standards).
