I. Introduction to iSCSIISCSI (Internet SCSI) supports sending SCSI commands to SCSI storage devices (targets) on remote servers from the client (initiator) via IP. The iSCSI qualified name is used to determine the initiator and target, and to use IQN.YYYY.MM. {Reverse Domain}:label format.}By default, network traffic is clear text to the 3260/TCP on the iSCSI

I. iSCSI Introduction Internet small computer system interface is an opportunity TCP/IP protocol, used to simulate SCSI high-performance local storage bus through an IP network, so as to provide data transmission and management for remote storage devices. As the San protocol, iSCSI expands the San across local and wide area networks, and provides location-independent data storage and retrieval through distr

In the previous article, we described how to build a simple iSCSI networked storage System, where the iSCSI initiator client hosts can connect and use all the disks and partitions shared by iSCSI Target, and in many cases, It is necessary to connect to a shared disk or partition by authorizing authentication, for examp

iSCSI is mainly through TCP/IP technology, the storage device side through the iSCSI Target (iSCSI targets) function, to provide the server side of the disk, and then through the iSCSI Initiator (iSCSI initialization user) functio

ISCSI (Internet SCSI): Enables the sending of SCSI commands from clients over IP to SCSI storage devices on remote serversThe SCSI fabric is based on the client/server model, and the typical application environment is that the devices are close to each other and the devices are connected by a SCSI bus. The main function of ISCSI is toTCP/IPon the networkHost System(initiator initiator) and storage device (
