Definitions
The following series of definitions are here to lay the ground work and context for the rest of the document. Here we define all the various objects and elements that can be managed using QuantaStor.
Storage System
The storage system is the object that represents the entire iSCSI server both from a physical and logical standpoint. This includes all the physical disks, fans, enclosures, power supplies and other physical elements of the system as well as all the logical elements including the storage pools, volumes, users, and storage clouds.
Storage Pool
The storage pool is an aggregation of one or more physical disks into a larger entity. Each storage pool has a single RAID type associated with it, and all storage volumes that are created within that storage pool inherit RAID type. For example, if a given storage pool of type RAID1 (mirroring) is made up to two 1TB disks, then there is 1TB of usable storage available to create storage volumes (LUNs) with.
Storage Volume
The storage volume is the most important object in the system as it represents the virtual disk device that is presented to the host a LUN. Each storage volume has a unique name and a unique target number and a unique IQN associated with it. Storage volumes can be created "thin" which means they do not use up any disk space until the device has been written to. Or "thick" which means that all the space for the storage volume is pre-reserved up front.
