Description:

This paper examines the capabilities of thin provisioning, enhancements to VMware vCenter in vSphere, and addresses best practices to ensure thin provisioned virtual disks are a benefit and work to their full potential. This paper also explains how thin virtual disks fit into the overall storage stack, and how virtual disk thin provisioning operates with array-based thin provisioning and dynamic expansion of virtual disks, VMFS volumes, and LUNs within the array.
