Recommended configurations
The detailed information for these recommended configurations includes the server, number and type
of processors, memory, internal and external storage. The configurations were evaluated for a given
workload: concurrent users, I/O operations per second, transactions/hour, and database size. The
configurations are based on testing done in HP’s performance integration lab to support the
implementation of online transaction processing servers using HP ProLiant servers running Red Hat
Linux and Oracle 11gR2 Enterprise Edition.
The configurations were determined based on the following utilization criteria:
CPU utilization of approximately 75% at the target workload
Buffer cache hit ratio of no less than 98% (indicating that the majority of the active database buffers
are in physical memory)
Disk I/O activity reflects a read/write ratio of approximately 80/20
HP ProLiant DL980 G7 server configurations examples:
4 or 8 processors

35 million business trans/hr (6,000 users), 70 million business trans/hr (13,000 users) and 150
million trans/hr (26,000 users)
Storage 2, 4 or 8 VMA3210 Memory Arrays
