VAAI NAS Plug-in

The VMware vSphere API for Array Integration (VAAI) integrates VMware vSphere with an Isilon cluster to clone virtual disks, to create thick virtual disk files, and to monitor disk space. The OneFS operating system uses VAAI to perform certain storage and management operations for VMware ESXi hypervisors. VAAI increases the speed at which virtual machine (VM) operations are performed for VMs that are stored on Isilon clusters
