Abstract

The invention discloses a single-hard disk iSCSI (Internet Small Computer System Interface) node which comprises a hard disk and an iSCSI target end control unit connected to the hard disk. The invention also discloses an iSCSI storage framework which comprises one or more front end switches, one or more IPSAN (Internet Protocol Storage Area Network) control servers, a rear end switch cluster and a single disk hard iSCSI node array. The invention also discloses a read-write method. The read-write method provided by the invention has the effects that the single-disk hard is adopted to form an iSCSI node and a storage framework is established through a high-speed Ethernetand and the IPSAN control servers, therefore, the cost of the storing system is lower, the capacity expansion can be carried out with low cost, higher practicability can be achieved, and higher performance can be ensured.

Description

technical field [0001] The present invention relates to a storage framework, in particular to an iSCSI (Internet Small Computer System Interface, Internet Small Computer System Interface) storage system carried on a TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) protocol. Nodes, architecture, and storage read and write methods. Background technique [0002] iSCSI is a network storage standard developed by IETF (Internet Engineering Task Force, Internet Engineering Task Force), the purpose is to use the IP protocol to connect storage devices together. By transmitting SCSI commands and data on the IP network, iSCSI promotes the transmission of data between the Internet and also facilitates the remote management of data. Due to its excellent data transmission capability, the iSCSI protocol is considered to be one of the key factors promoting the rapid development of the SAN (Storage Area Network, Storage Area Network) ...
