Embodiment Construction

[0045] The host's iSCSI-based access to the storage system follows the SCSI client / server model. The client is usually the host, which initiates read and write operation requests to the server; the server is usually the storage system, which responds to the client's request. In the field of storage, the client acts as the initiator (Initiator) to actively issue storage operation instructions, and the server acts as the target (Target) to respond passively and execute the storage operation instructions of the client.

[0046] In order to meet the transmission reliability requirements of SCSI block data (block data) input and output, the iSCSI standard uses a connection-based TCP protocol to carry the iSCSI protocol. Therefore, locating a target on the network requires the IP address and TCP port number of the network node where it is located, which is called the portal of the target. The initiator establishes a connection with the target according to the entry of the target, an...

Abstract

The invention relates to a separate method of IP SAN that via margin node connecting the external network, which comprises: on the margin node, building the connection with the initiator of external network; on the margin node, building the connection with the target of IP SAN accessed by said initiator; transferring loaded iSCSI load between the said two connections. With said invention, the external network can not obtain the internal structure and route of IP SAN, and directly access the memory system, to improve the data safety. And the SAN can define the IP address freely, to increase its independence.

Description

technical field [0001] The present invention relates to SAN (Storage Area Network, storage area network) technology, in particular to an isolation method and isolation device for an IP (Internet Protocol, Internet Protocol) SAN network. Background technique [0002] After the traditional storage system has experienced SCSI (Small Computer System Interface, minicomputer system interface) cable direct connection mode, FC (Fibre Channel, Fiber Channel) has always been the mainstream. The emergence of iSCSI (Internet Small Computer System Interface, Internet Small Computer System Interface) provides another means of transmitting SCSI commands, which enables storage resources to be shared within the IP range. [0003] iSCSI is a standard formulated by IETF (Internet Engineering Task Force, Internet Engineering Task Force), which is used to map SCSI data blocks into Ethernet data packets, that is, the SCSI protocol used by data storage devices is carried on TCP / IP for transmission...
