vStorage Thin Provisioning, a key
component of VMware vSphere™, is a technology that redefines storage
provisioning by allocating space on demand to the virtual disks. We recently
published a paper that gives the details of this feature and discusses
experiments conducted to study the performance of thin-provisioned disks in a
VMware vSphere™ environment.
The data we have collected reveals
thin and thick disks perform similarly on various workloads.
provisioned disks show similar performance trends as thick disks do when
scaled across different hosts.
fragmentation has negligible impact on the performance of thin provisioned
- There is insignificant performance impact on existing
thick disks if thin provisioning is implemented on a shared array.
above graph shows that the performance of a thin provisioned disk matches the
performance of a thick disk. For more details on the environment of these tests
and the experiments conducted we invite you to read the full whitepaper at http://www.vmware.com/pdf/vsp_4_thinprov_perf.pdf.
