The primary objective was to obtain performance and scalability metrics to assist the bank client. The modest test configuration consisted of a pair of 4 CPU Logical Partitions (LPARs), along with a small SAN/Disk Array combination. The first partition housed the Distra application, and Oracle 10G installed on the other. Significantly the Distra Switch application was installed with no change to the standard product that has been run across a range of other platforms including HP, Sun and Dell, save a few minor installation script changes to accomodate the System P Platform. Furthermore the Distra Switch application ran immediately and following a 24 hour period of limited system tuning, was switching above the target rate of 1200tps.
A number of formal tests were then run at successively incrementing throughput rates. Distra's load simulators were used to generate simulated payments transactions at a specified and constant rate. During each test, system metrics were captured to measure CPU and resource utilization as well as actual processing throughput.
The results showed that this test configuration is capable of 1250 completed business Transactions Per Second at 37% CPU utilization.
The next series of tests involved repartitioning the servers into a pair of 2 CPU LPARS. The Distra Switch exhibited similar throughput levels at the expected higher CPU Utilization.
Distra hopes to return to the Innovation Center in the near future to finalize certification on IBM's DB2 Database.
