Linux tgtadm: Setup iSCSI Target ( SAN )

iSCSI = Internet SCSI
iSCSI는 TCP/IP 기술을 사용하여 SCSI 프로토콜을 전송하여
네트워크상의 다른 시스템에 탑재된 하드 디스크를 연결하기 위한 구조.
iSCSI target -> server
iSCSI initiator -> client
iSCSI initiator use CRC for data integrity
TGT = target framework
STGT = SCSI target framework
IQN = iSCSI Qualified Name

LUN = iSCSI Logical Unit
DM = device mapper
CHAP = User/Password authentication

How Do I Setup an iSCSI Server in Redhat Enterprise Linux (RHEL) 6?
http://samcaldwell.net/index.php/technical-articles/3-how-to-articles/103-how-do-i-setup-an-iscsi-server-in-redhat-enterprise-linux-rhel-6
The iSCSI server is not CPU intensive, but it is (obviously) an I/O intensive server.
This means that a single quad-core CPU can easily be overkill,
but a slow disk controller or slow networking can kill the project before it reaches production.
it would have been a better plan to use smaller SFF disks to achieve higher performance over more disks.
the operating system was loaded on 2*160GB (RAID 1).
The iSCSI LUN exposed by the server existed on 4*1.5TB (RAID10).
Use two or more NICs per iSCSI server to access the storage network.
In most cases, a minimum of four NICs just for storage is appropriate.

Quick notes on using TGT as a iSCSI target on Linux
http://billscontinuinglife.com/2011/03/quick-notes-on-using-tgt-as-a-iscsi-target/
Install iscsi target:
yum install scsi-target-utils
Check to see if disks are available:
fdisk -l
Start and enable the daemon at boot time:
service tgtd start
create the target and define its name:
tgtadm –lld iscsi –op new –mode target –tid 1 -T iqn.2001-04.local.somecompany:storage.disk2
add a LUN to the target:
tgtadm –lld iscsi –op new –mode logicalunit –tid 1 –lun 1 -b /dev/sdb
Enable the target to accept any initiators:
tgtadm –lld iscsi –op bind –mode target –tid 1 -I ALL
Check to see status
tgtadm –lld iscsi –op show –mode target
