Performance Implications of Storage I/O-Enabled SSD Datastores in vSphere 6.5

Version 1

    This paper shows the advantages of using Storage I/O Control (SIOC) to manage shared storage using SSD. The study shows that administrators can set the performance expectation of VMs in terms of IOPS using explicit numbers or proportional values in vSphere 6.5, and that high priority VMs achieve more IOPS compared to low priority VMs.
