11.2 ZERO-COST VIRTUAL MACHINE CLONING<br />
Customers who deploy <strong>VMware</strong> on <strong>NetApp</strong> can leverage <strong>NetApp</strong>’s patented FlexClone technology using<br />
<strong>NetApp</strong>’s Rapid Cloning Utility. The RCU is a vCenter Server Plug-in that provisions zero-cost, or<br />
prededuplicated, <strong>VMware</strong> virtual machines <strong>and</strong> datastores. The RCU is available with VI3, vSPhere support<br />
will be available with the 2.2 release.<br />

11.3 STORAGE THIN PROVISIONING<br />
You should be very familiar with traditional storage provisioning <strong>and</strong> with the manner in which storage is<br />
preallocated <strong>and</strong> assigned to a server, or in the case of <strong>VMware</strong>, a virtual machine. It is also a common<br />
practice for server administrators to overprovision storage in order to avoid running out of storage <strong>and</strong> the<br />
associated application downtime when exp<strong>and</strong>ing the provisioned storage. Although no system can be run<br />
at 100% storage utilization, there are methods of storage virtualization that allow administrators to address<br />
<strong>and</strong> oversubscribe storage in the same manner as with server resources (such as CPU, memory,<br />
networking, <strong>and</strong> so on). This form of storage virtualization is referred to as thin provisioning.<br />
