Summary

Summary conclusions for comparing IBM® System z9® to IBM System z10™.

In this specific customer setup of importing data into an Oracle 10g R2 database running Red Hat Linux® under z/VM® 5.3 on a System z®, we could show an improvement of a factor of two when migrating from System z9 to System z10.¹ The factor of two is based on the compute intensive workload which was neither burdened by heavy network load nor by the storage server which handled the data rates of up to 250 MB/sec easily.

The import process itself may be further improved by using the new Oracle Data Pump utility or by creating multiple export files - for example one per tablespace, and importing them in parallel. Another alternative might be to use ASM to manage the database files.

This very impressing result helps confirm that upgrading to the IBM System z10 significantly enhances the capabilities of enterprise IT customers.

¹ Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.
