It is used to access the storage on your network over TCP/IP using block-level data transfers.
There is often a comparison between NFS vs iSCSI. The key difference is NFS is file-level implementation whereas iSCSI is a block-level implementation.
In block-level implementations such as iSCSI and Fiber Channel, the storage array offers up a collection of blocks to the client, which then formats that raw storage with whatever file system it decides to use.
