A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage. SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage .
Labels or serial numbers stored in a logical unit's storage volume often serve to identify the logical unit. However, the LUN is the only way for an initiator to address a command to a particular logical unit, so initiators often create, via a discovery process, a mapping table of LUN to other identifiers.
Internet Small Computer Systems Interface or iSCSI (/ aɪ ˈ s k ʌ z i / ⓘ eye-SKUZ-ee) is an Internet Protocol-based storage networking standard for linking data storage facilities. iSCSI provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. iSCSI facilitates data transfers over intranets and to manage storage over long distances.

The network switch is only used to connect the server within a cell 0. A cell 1 contains k=n+1 cell 0 cells, and similarly a cell 2 contains k * n + 1 dcell 1 . The DCell is a highly scalable architecture where a four level DCell with only six servers in cell 0 can accommodate around 3.26 million servers.
A virtual storage area network (virtual SAN, VSAN or vSAN) is a logical representation of a physical storage area network (SAN). A VSAN abstracts the storage-related operations from the physical storage layer, and provides shared storage access to the applications and virtual machines by combining the servers' local storage over a network into a single or multiple storage pools.
High Performance Storage System (HPSS) is a flexible, scalable, policy-based, software-defined hierarchical storage management (HSM) product developed by the HPSS Collaboration. It provides scalable HSM, archive, and file system services using cluster, LAN and storage area network (SAN) technologies to aggregate the capacity and performance of ...
