With today’s technologies, you can run large mission-critical databases on virtual machines safely and securely. Creating virtual servers to host databases, instead of running them on physical servers, has the potential to provide a number of time- and cost-saving benefits to your organization, as you can take advantage of the many powerful features and tools that VMware vSphere offers including vMotion, DRS, and much more. We designed this functional stress test to test the complete hardware and software stack, which was comprised of VMware vSphere, Cisco UCS, and EMC VMAX Cloud Edition storage. The EMC VMAX Cloud Edition absorbed the workload’s requested storage throughput. The Cisco B200 M3 servers were able to supply the processing power necessary for the workload. The Cisco Nexus switches, despite using only at a fraction of their maximum capacity in this test, allowed for the required network throughput, including the vMotion traffic. This physical infrastructure, used in concert with VMware vSphere, allowed vMotions to occur and the RAC application to remain active despite the migration scenarios we tested, some of which were more extreme than database administrators would typically encounter. The tests experienced no false ejections or RAC cluster fencing operations, showing the mature capabilities of VMware vMotion technology.
As we showed in our tests using Cisco UCS server hardware and EMC VMAX Cloud Edition storage, VMware vSphere with vMotion made it easy to shift large databases and other workloads from one server to another in a cluster, without application downtime. By choosing to run your large databases on VMware vSphere virtual machines, you can reap the benefits of VMware vMotion for the ultimate agility and flexibility in managing your mission-critical database workloads.
