Just to share experience :
We've just move our 3 Terabytes Oracle 8i RDBMS (DSS/OLAP : mostly
sequential-read patterns) from an IBM ESS 2105-800 (72 disks of 73 GB,
RAID5) to an EMC DMX-2000 (232 disks of 73 GB, RAID0+1).
Workload tests have shown an improvement of 40% of Oracle throughput without
any other change or specific tuning (same software config, same hardware).
Server : Fujitsu Primepower 900 with 10 Sparc64-V 1,.3 Ghz CPU, 40 GB RAM.
I/O : 8 x load-balanced Emulex LP9802 2Gb FC-AL (no SAN)
Software : Solaris 8 02/02 , VxVM 3.5 (no FS for Oracle : raw-devices),
VxDMP (NO POWERPATH, despite EMC advices/marketting)
The best peek throughput measured between PW900 and EMC DMX is currently 720
MB/s.
The best peek throughput measured between PW900 and IBM ESS was 450 MB/s.
Next step is moving from PW900 (10 CPU 1.3 Ghz, 40GB RAM, 8xEmulexLP9802) to
PW1500 (14 CPU 1.9 Ghz, 112 GB RAM, 12xEmulexLP10000).
I will let you know the results.
