Greg Rahn was kind enough to recite in his blog what Oracle has disclosed about the first Exadata testers. I don’t track hardware model details, so I don’t know how the testers’ respective current hardware environments compare to that of the Oracle Database Machine.
Each of the customers cited below received “half” an Oracle Database Machine. As I previously noted, an Oracle Database Machine holds either 14.0 or 46.2 terabytes of uncompressed data. This suggests the 220 TB customer listed below — LGR Telecommunications — got compression of a little under 10:1 for a CDR (Call Detail Record) database. By comparison, Vertica claims 8:1 compression on CDRs.
Greg also writes of POS (Point Of Sale) data being used for the demo. If you do the arithmetic on the throughput figures (13.5 vs. a little over 3), compression was a little under 4.5:1. I don’t know what other vendors claim for POS compression.
Here are the details Greg posted about the four most open Oracle Database Machine tests:
- Currently runs on two IBM P570s with EMC CX-30 storage
- 4.5TB of Call Data Records
- Exadata speedup: 10x to 72x (average 28x)
- “Every query was faster on Exadata compared to our current systems. The smallest performance improvement was 10x and the biggest one was 72x.”
- Currently runs on HP Superdome and XP24000 storage
- 220TB of Call Data Records
- “Call Data Records queries that used to run over 30 minutes now complete in under 1 minute. That’s extreme performance.”
- “Oracle Exadata outperforms anything we’ve tested to date by 10 to 15 times. This product flat out screams.”
- Currently runs on IBM P570 (13 CPUs) and EMC CLARiiON and DMX storage
- 5TB of retail data
- Exadata speedup: 3x to 50x (average 16x)
