Table 4. DL980/P2000 supported Expansion Slot Configurations

Expansion Slots

 Standard Main I/O with 5 Gen2 slots: (3) x4 PCI-Express; (2) x8 PCI-Express

 PCIe Option with 6 slots: (1) x4 Gen1 PCI-Express; (1) x4 Gen2 PCI-Express (4) x8 Gen2 PCI-Express

 Low Profile Expansion Option with 5 Gen2 slots; (1) x4 PCI-Express; (4) x8 PCI-Express

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 throughput, and database size. The configurations are based on testing done in HP’s Oracle integration lab

using HP DL980 G7 ProLiant servers running Red Hat Enterprise Linux (RHEL) and Oracle 11gR2 Enterprise Edition.

The configurations were determined based on the following utilization criteria:

 CPU utilization up to 90% at the target workload

 Process Global Area (PGA) cache hit ratio 99% or higher with very low counts of 1 or multipass PGA executions

 Disk I/O activity reflects a read/write ratio of approximately 95/5

The focus of this reference configuration document is the data mart or data warehouse type configuration, based on

the ProLiant DL980 G7.

RAM

1024GB PC3-10600R-9 expandable to 2TB

Note that the recommended 1024GB is the minimum RAM for this reference configuration. Generally, for Oracle

Data Warehousing environments, as workload demands grow, increasing RAM provides performance benefits

(requires RHEL 6.x). If the workload consists of a large number of small-to-medium sized queries hitting the same data

(for example, last week’s sales query), performance and throughput can be increased by caching results in memory.

Additional network capacity can be added to support larger numbers of client connections however most DW

workloads have very few client connections.
