This article will help you learn how to set up/configure iSCSI on Linux/Unix-based systems. iSCSI stands for Internet Small Computer System Interface, which is an industry-standard protocol mainly used to share the storage device over the TCP/IP layer. Unlike Samba or NFS, which work at the file system level, iSCSI works only on the block-level device. Most block-level storage devices have the capability of built-in work to share data across volumes. Learn more about iSCSI and how to use it here.
