  • Evaluation of the performance implications caused by z/VM® host CPU and memory constraints on different workload types running in virtual systems with Linux™ on System z®. The following workloads types were investigated:
    • Database Business Intelligence (BI) workload
    • Transactional WebSphere® Application Server (WAS) workload
    • File system I/O workload
    • Java™ workload
    • Network workload
  • Evaluation of the sensitivity of these different workload types against CPU and memory constraints at the host system
  • Evaluation of the efficiency of
    • the z/VM memory subsystem when dealing with shortages of real memory
    • the z/VM scheduling subsystem when dealing with shortages of real processors
    • the z/VM paging subsystem when either EDEV-SCSI or ECKD™ based paging disks are used.
