Implementing iSCSI shared storage under Linux systems

implementing iSCSI shared storage under Linux systems

iSCSI Introduction:iSCSI is a block-level share of SCSI packets based on TCP/IP transport encapsulation, which is also the C/S architecture model, and the server side provides the storage devices required by the client. The client only needs to mount it as a storage device on its own host to partition and format it .

Implement iSCSI 2 characters required:

iSCSI target (server)

where the storage resource resides iSCSI the server is called "target". iSCSI target is typically a hard disk storage device. Most of the current operating systems provide client software initiator that are used in conjunction with iSCSI Target.

iSCSI Initiator (client)

Initiator is iSCSI the service side of the transport. A typical initiator has a common purpose, as an adapter for an iSCSI Bus, instead of a physical SCSI device (like a hard disk or tape). ISCSI initiator transmits SCSI commands over an IP network.

Experimental environment

192.168.1.123 CentOS 6. 7 x86_64 Target Server

192.168.1.124 CentOS 6. 7 x86_64 Initiator Client

Experimental steps:

A. Deploy target server

1) First in Target Server add a new hard disk on the Setting up the iSCSI target Environment
