1.Target-side configuration The target side is the disk array or other host with disk. The Iscsitarget tool maps disk space to the network, and the initiator side can find and use the disk. Note that a target host can map multiple target to a network, that is, multiple block devices can be mapped to the network. 1) package Iscsitarget You can download the latest version from http://sourceforge.net/projects/iscsitarget/files/. 2) Compile and inst
reliable transmission of large amounts of data between host systems (initiator initiator) and storage devices (target targets) on TCP/IP networks.The topology of the complete iSCSI system is as follows:iSCSI simply means that the SCSI instructions are encapsulated in the TCP/IP protocol and transmitted over Ethernet.

To enable iSCSI to read and write, in addition to the use of specific hard devices, the server can also be emulated as the initiator or target of iSCSI, using existing processors to achieve iSCSI connectivity with ordinary Ethernet card resources. iSCSI, the Internet SCSI,

accessing an iSCSI target device is:① when a user makes an access request to a Iscsitarget device, the application accesses the file system through a system call:The ② file system interprets this I/O command, analyzes the device and address where the I/O command resides, and then sends the request to the SCSI upper layer driver:③SCSI the upper-level driver converts the appropriate I/O command to a SCSI command and sends it to the
device is: ① When a user sends an access request to an iscsitarget device, the application accesses the file system through a system call: ② The file system interprets this I/O command, analyzes the device and address where the I/O command is located, and then sends the request to the SCSI upper-layer driver: ③ The SCSI upper-layer driver converts the corresponding I/O commands into SCSI commands and sends them to the iSCSI
