What is iSCSI? and how it works ?

iSCSI stands for internet SCSI, or internet Small Computer Systems Interface.

iSCSI is the transmission of SCSI commands and data over IP networks.

When an application attempts to read from an iSCSI device, the SCSI read command is encapsulated inside an IP packet. The IP packet is then routed just like any other IP packet on the network. When the IP packet reaches its destination, the encapsulation is stripped off and the SCSI read command is interpreted by the iSCSI drive.
