iSCSI on Linux

iSCSI Intro

Implements SCSI Protocol over TCP/IP
Similar to Fibre Channel but can be implemented with cheap NICs
Decent performance with 1Gbit

Two components: initiator(client) + target(server)
Initiator/Target may be implemented in software or hardware
Linux Initiator is implemented in kernel module (SCSI HBA) + userspace daemon

Each initiator/target has a WWN (IQN)
Uniquely identifies an initiator or target
Generated with iscsi-iname
