Virtualizing Performance-Critical Database Applications in VMware vSphere
ثبت نشده
چکیده
VMware® vSphereTM 4.0 with ESXTM 4.0 makes it easier than ever to virtualize demanding applications such as databases. Database workloads are widely acknowledged to be extremely resource-intensive. The large number of storage commands issued and the network activity to serve remote clients place significant challenges on the platform. The high consumption of CPU and memory resources leaves little room for inefficient virtualization software. The questions we're often asked are: Is it possible to run a heavy-duty database application in a virtual machine? Can a virtualized environment handle high storage IOPS and network packets/second? While database applications have been successfully deployed in virtual machines since the earliest versions of VMware ESX, vSphere 4.0 incorporates many performance-related enhancements such as: PVSCSI, a new paravirtualized SCSI adapter for virtual machines Improved I/O concurrency for enhanced storage performance Improved interrupt coalescing and delivery mechanisms for better I/O throughput Hardware support for memory management unit virtualization Improved CPU scheduler that can better support these larger I/O intensive virtual machines By quantifying performance gains achieved as a result of these changes for a very high-end Oracle database deployment (with a much larger resource footprint than one would expect to see in most production environments) and highlighting the overall system performance, we show that large database applications deployed in virtual machines have excellent performance.

The performance of three Hadoop applications is reported for several virtual configurations on VMware vSphere 5 and compared to native configurations. A well-balanced seven-node AMAX ClusterMax system was used to show that the average performance difference between native and the simplest virtualized configurations is only 4%. Further, the flexibility enabled by virtualization to create multipl...
