Embodiment Construction

[0016] The invention is a computer server or an Ethernet switch, by adopting the iSCSI target steering function, and then realizing the method of managing multiple storage devices based on the iSCSI protocol and their information in a TCP / IP protocol network.

[0017] At the beginning of the iSCSI switch or iSCSI management server; that is, the application server, you only need to configure a single iSCSI IP address to connect to multiple iSCSI destination storage arrays;

[0018] The device intercepts input and output (IO) traffic during the iSCSI logical unit number discovery or acceptance registration (login) stage, and then uses a conventional Ethernet switching mechanism to guide the IO traffic to the corresponding LUN;

[0019] The iSCSI storage array can be any iSCSI target storage array that supports the iSCSI standard.

[0020] This device can be a switch or a server. If the above functions are implemented on a network switch, this device is an iSCSI switch, that is,...

Abstract

The invention relates to a method for managing several disc memory arrays via exchanger or mange server, wherein it comprises: adding iSCSI steering engine on the Ethernet exchange or calculation server, adding the scanning and recognizing function on the iSCSI target terminal memory array of LUN, adding the DHCP calculation module function for managing the iSCSI target terminal memory array IP address, to form iSCSI exchanger or iSCSI manage server; via distributing the IP address of single iSCSI, connecting several iSCSI target memory arrays; separating the access and the connecting of iSCSI protocol; the IP address of each memory array is distributed by the exchanger with dyanamic host distribution protocol DHCP; with said invention, iSCSI manage server only inquires the iSCSI protocol. The invention can manage the maximum iSCSI target arrays supported by Ethernet exchanger, to reduce the complexity when expanding capacity and property of memory system, and reduce relative cost.

Description

technical field [0001] The invention relates to a computer network storage technology. Background technique [0002] Through the efforts of the International Standardization Organization IETF, the "Internet Small Computer System Interface" protocol (hereinafter referred to as iSCSI) has become an industry standard. The protocol allows SCSI clients and data input and output (IO) devices to communicate with IP-based devices without distance limitations. The details of this standard can be found in: http: / / www.ieff.org / rfc / rfc3720.txt . [0003] The iSCSI protocol enables SCSI commands to be packaged in TCP / IP packets for transmission over an IP network. [0004] With the emergence of a large number of storage disk arrays based on the iSCSI protocol, it becomes increasingly difficult and complicated to expand and manage these storage systems. IP address management for all iSCSI storage arrays and servers must implement bidirectional and different iSCSI destination storage a...
