One of the essential requirements for a platform supporting enterprise datacenters is the capability to support the extreme I/O demands of applications running in those datacenters. This performance study shows that vSphere can easily handle demands for high I/O operations per second. Experiments discussed in this paper demonstrate that a vSphere 5.0 virtual platform can easily satisfy an extremely high level of I/O demand that originates from the hosted applications, as long as the hardware infrastructure meets the need. Testing was performed at EMC labs with a vSphere system that utilized Symmetrix VMAX storage and Emulex LPe12002 HBAs.
