Explanation:
Storage I/O Control (SIOC) is used to control the I/O usage of a virtual machine and to gradually enforce the predefined I/O share levels. SIOC is supported on Fibre Channel and iSCSI connected storage in ESX/ESXi 4.1 and 5.0. With ESXi 5.0 support for NFS with SIOC was also added. Datastores with multiple extents or Raw Device Mapping (RDM) are currently not supported.
