Framework and requirements for cloud computing 1

3.2.2 DSF local storage: A physical storage to be integrated.

NOTE – DSF local storage includes on-premises storage such as main memory, non-volatile memory express (NVMe),
solid state disk, hard disk drive, serial attached small computer system interface (SCSI), Internet SCSI storage and
network-attached storage, object-based storage device, intelligent storage device, etc. and cloud storage with different
management units such as block, object and file.
3.2.3 single virtual volume: A virtual storage unit provided in forms of a block device, disk, or object
device.
NOTE – Customer of single virtual volume includes an end-user, server, operating system and application.
3.2.4 storage virtualization: An abstraction of storage resource to provide logical storage.

NOTE – The abstraction includes consolidating the different type of storages into a virtual storage pool as well as dividing
a virtual storage pool into a single virtual volume.
3.2.5 virtual storage pool: A logical storage by integration of DSF local storage.
