Manage vVol objects

Virtual volumes are encapsulations of virtual machine files, virtual disks, and their derivatives. There are several types of vVol objects that correspond to an individual virtual volume, including a VMDK vVol (data vVol), Config vVol, Memory vVol, and Swap vVol.

Table 1. Types of vVolsDescribes the different types of vVols.
vVol Type	Description
VMDK (Data) vVol	The VMDK vVol, displayed as Data vVol in Unisphere, contains the vDisk file, or the hard disk drive, for the VM.
Config vVol	The Config vVol contains settings, configuration, and state information for the VM. This includes vmx, nvram, and log files.
Memory vVol	The Memory vVol contains a complete copy of the VM memory as part of a with-memory VM snapshot.
Swap vVol	The Swap vVol is created when VMs are powered on and contain copies of the VM memory pages that are not retained in memory.

Table 2. vVol attributesDescribes the attributes associated with vVols.
