Test results

The test results together with observations are analyzed in this section.

Reference workload - Java workload
In z/VM® 6.2 Live Guest Relocation with Linux™ Middleware a Java™-based workload was analyzed with respect to its relocation behavior when various ISFC logical link configurations were used.
File system I/O workload
Tests were run to investigate the influence of scaling the fio throughput and the influence of fio throughput on quiesce times.
Transactional database workload
Tests were run to show the influence of Linux™ guest size and the Oracle Database on the relocation process as well as the influence the number of SwingBench users has on the relocation process.
Various workloads - number of memory passes and amount of data transferred
To keep the quiesce time (the time during which a guest is stopped during the relocation process) as small as possible, the live guest relocation process performed by z/VM® is organized into a number of passes.
Curing CPU constraints by offloading guests with high CPU load
In this scenario how the CPU pressure generated by several Linux™ guest systems working in parallel on the source host system can be alleviated by relocating the Linux™ guest with the highest CPU load (the transactional database workload) is investigated.
