A new blog posted by the Red Hat and IBM Performance Teams showcases the new performance results for KVM, which is incorporated in both Red Hat Enterprise Linux and Red Hat Enterprise Virtualization:
This latest performance mark was achieved on the IBM System x3850 X5 host server with Qlogic QLE 256x Host Bus Adapters, Red Hat Enterprise Linux 6.3 hypervisor and Red Hat Enterprise Linux 6.3 guests. During testing by IBM, KVM demonstrated its ability to handle I/O rates at the storage performance levels required by enterprise workloads, with four guests handling more than 1.4 million I/Os per second (IOPS). The results are further proof that virtualized workloads can maintain consistent high performance as compared with baremetal deployments … read on.
