iSCSI stands for Internet Small Computer Systems Interface. It is an Internet Protocol that allows multiple servers and users to access network drives remotely over a TCP/IP network by setting up a shared storage network. iSCSI components include the iSCSI target which is the server that stores and allows access to storage and iSCSI initiator which is the hardware installed on a client to send data. A basic Ethernet port or a Host Bus Adapter (HBA) is what is required to connect iSCSI targets and initiators to a network. Both components are identified by a unique name known as iSCSI Qulified Name (iQN).
What is iSCSI Target?
iSCSI target as discussed above is the server that stores the storage and allows access to it. It can be a dedicated physical device on a network or an iSCSI software-configured logical device on a networked storage server. It is the remote storage that appears as a local drive on a host system. The iSCSI protocol then links the host with the storage over IP networks like LAN and WAN or Internet.
