Storage volumes are also known as array LUNs.ExtentThe first level of presentation of a storage volume, which can be div

12、ided into multiple extents or a single extent (if the entire storage volumes capacity is used)DeviceA storage object formed from one or more extents or devices. A devices also has a RAID level of 0, 1, or C. Devices can be used to create virtual volumes.Virtual VolumeA VPLEX volume that is created a
