If an add-on SAS controller is installed into the DL980 it may be possible the SAS controller could interfere with the
performance of any VMA pass-thru cards installed in PCIe x8 slots 9 and 11 on the Standard Main I/O. You may want to
move any VMA pass-thru cards to alternate PCIe x8 slots 6 and 16.
Note:
It is not supported to use slot 1 for any HP VMA PCIe Pass-Thru Cards due to low
I/O performance (PCI-x 100 MHz).
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
 256 - 1024 GB of memory (4P upgradeable to 1TB) (8P upgradeable to 2TB)
 8, 15, and 25 TB database sizes
 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
