Storage configuration details

Internal storage

The DL980 G7 recommended configurations use four internal drives configured with RAID1 for the OS and 11gR2

software. The server supports up to eight internal drives, so additional drives can be added for staging data, logs, or

other requirements.

Write Cache, and Smart Array Advanced Pack (SAAP)

External storage

The HP Scalable Warehouse Solution for Oracle reference configuration is based on a model of a core-balanced

architecture which allows for a configuration that is initially balanced and provides predictable performance. This

core balanced architecture is sized for an optimum number of storage components to drive a certain number of CPU

cores. Each CPU core has a maximum throughput of information that can be processed. If we take the per core rate

and multiply times the number of CPU cores, we then have the processing rate for the entire system. To ensure

balanced performance we must ensure that there are minimal bottlenecks in the system that would prevent the CPUs

from reaching their maximum throughput.

It is also possible to increase storage capacity without adding more CPU cores by using larger drives; however

increasing the capacity beyond the optimized configuration will not increase performance. Important to note is that

adding more data but still querying the same sized ranges per query will not decrease performance. Table 8

summarizes the configuration specifics and capabilities of the fibre channel version of the P2000, the P2000 G3

MSA FC.
