Configure iSCSI Target (Server) & Initiator (Client) in Linux (RHEL 7) | Nehra Classes
Install & Configure iSCSI Target (Server) as well as iSCSI Initiator (Client) in RHEL 7 (CentOS 7):
=========
iSCSI stands for Internet Small Computer Systems Interface.
iSCSI is a transport layer protocol that works on top of the Transport Control Protocol (TCP).
It enables block-level SCSI data transport between the iSCSI initiator and the storage target over TCP/IP networks.
iSCSI supports encrypting the network packets, and decrypts upon arrival at the target.
SCSI is a block-based set of commands that connects computing devices to networked storage, including spinning up storage media and data reads/writes.
The protocol uses initiators to send SCSI commands to storage device targets on remote servers.
Storage targets may be SAN, NAS, tape, general-purpose servers – both SSD and HDD – LUNs, or others.
The protocol allows admins to better utilize shared storage by allowing hosts to store data to remote networked storage, and virtualizes remote storage for applications that require direct attached storage.
NFS, Samba, AFS (NAS Based Tools) work at filesystem level, whereas iSCSI (SAN Based like AoE) works at block level.

BLOCK = Block-device based LUN Storage Space like Disk e.g. /dev/sdb.
FILEIO = File based LUN Storage Space like file created with dd command.
PSCSI = (SCSI Pass-through) Physical Disk based LUN Storage Space like CD-ROM.
RamDisk= Ramdisk based LUN Storage Space for higher IO speed.

-tpg1 = target portal group
-acl = provide the access to luns with the help of client iqn number
-luns = which lun has to mapped or to be accessed by client
-portals = network cards, ip address, port number
