By the iSCSI (InternetSCSI) standards, was initiated by IBM, Cisco co-sponsored technical standards, after three years of constant improvement in 20 versions, and finally get IETF approval. This will attract more companies to participate in the development of related products, will push more customers to use iSCSI solutions. With iSCSI technology improved, the data block level Storage Applications will become more common, storage resources General , Data sharing capabilities will be greatly enhanced and easier to Management . With Gigabit Ethernet and Gigabit Ethernet mature Network Development, IP storage is bound by its cost-effective, universal, non- Geography Restrictions on the rapid development advantages, iSCSI technology will be combined SCSI, TCP / IP, the common open Network Storage New situation. SCSI (SmallComputerSystemsInterface, Small Computer System Interface) technology is to be Disk , Magnetic tape Extensive use of storage devices such as standard, born from 1986 until the present, still maintained a good momentum of development; also adopted the TCP / IP protocol in the network is the most common and most mature protocol, and IP network infrastructure is improved . This points to the infinite expansion of iSCSI provides a compacted foundation.
ISCSI protocol defines the TCP / IP network to send, receive block (block) level of rules and methods of storing data. Sending end to encapsulate SCSI commands and data TCP / IP packet and then through the network forwarding, the receiver received TCP / IP package, to restore the SCSI commands and data and execution will return after the completion of the SCSI commands and data and then package to the TCP / IP packet re-transmission back to the sender. So that end users view, use the remote storage device like a visit to the local SCSI device as simple and convenient. Support iSCSI technology Service And storage devices to connect directly to existing IP Switch And Router And, hence, iSCSI technology is easy to install, low cost, without geographical restrictions, good interoperability, easy management advantages. Early in the first half of 2001, IBM introduced I would PS torage200i, is recognized as the first market-based iSCSI protocol products, this product's there, who live in a era of information explosion but can not afford Optical fiber Channel SAN environment for small and medium high-cost users, has great appeal; in October 2001, Cisco also launched the SN5420 storage router based on IP standards and SAN (StorageAreaNetwork, storage area network) standard, can provide current a LAN (LocalAreaNetwork, local area network), WAN (WideAreaNetwork, wide area network), optical fiber, and interoperability between SAN devices, the first IP network and SAN built a bridge between. Now, there are more vendors involved in the development of iSCSI products, such as Intel has introduced a storage card IPStorageiSCSIPRO/1000T, the protocol conversion that is packaged, to restore TCP / IP packet step up the implementation of the transfer to the card, significantly reducing the server Processor The occupancy rate. There are also Chip , Board Manufacturers to develop iSCSI products, such as Adaptec, Qlogic, iStor so.
We believe that in the near future, iSCSI storage technology will bring major changes in the industry. With iSCSI technology improved, the data block-level storage applications will become more common, common storage resources, data sharing capabilities will be greatly enhanced and easier to manage. With Gigabit Ethernet and Gigabit Ethernet mature development, IP storage is bound by its cost-effective, universal, no geographic restrictions on the rapid development advantages, iSCSI technology will be combined SCSI, TCP / IP, together to create a network storage of a new situation!
