	RFC 3720 (rfc3720) - Internet Small Computer Systems Interface (iSCSI)
		iSCSI Login The purpose of the iSCSI login is to enable a TCP connection for iSCSI use, authentication of the parties, negotiation of the session's parameters and marking of the connection as belonging to an iSCSI session.
		The iSCSI name of a SCSI device is the principal object used in authentication of targets to initiators and initiators to targets.
		In iSCSI the I_T_L nexus is identified by the LUN and the session identification (the session identifies an I_T nexus).

	iSCSI Review
		The need in a new standard was so strong that during 14 months after the proposal on the iSCSI by IETF in February 2000 we got a lot of devices demonstrating capabilities of their interaction.
		Below is a model of the iSCSI protocol levels which allows us to get an idea of an encapsulation order of SCSI commands for their delivery through a physical carrier.
		If the iSCSI Login Phase is completed successfully the target confirms the login for the initiator; otherwise, the login is not confirmed and a TCP connection breaks.

	ISCSI - Wikipedia, the free encyclopedia
		The iSCSI market is growing steadily, and should improve in performance and usability as more organizations deploy Gigabit and 10 Gigabit networks, and manufacturers integrate iSCSI support into their operating systems, SAN products and storage subsystems.
		In the context of computer storage, iSCSI allows a machine to use an iSCSI initiator to connect to remote targets such as disks and tape drives on an IP network for block level I/O.
		iSCSI is one of the longest palindromes in the ICT industry.

		Standards Track [Page 20] RFC 3720 iSCSI April 2004 Command numbering starts with the first login request on the first connection of a session (the leading login on the leading connection) and command numbers are incremented by 1 for every non-immediate command issued afterwards.

	iSCSI
		The rise in attention to iSCSI is attributable to the speed improvements that have been made, and that are planned, for network signaling.
		iSCSI (and other IP based storage initiatives) represent a change in direction for storage attachment to servers and SANs and this could possibly change the assumptions around the deployment of storage.
		Once the nuances of iSCSI are worked out in the initial products and interoperability tests, manufacturers of end-node devices (storage subsystems, tape systems, large RAID devices) will begin to build iSCSI as native interconnects.

	iSCSI - a definition from Whatis.com (Site not responding. Last check: 2007-10-17)
		The iSCSI protocol is among the key technologies expected to help bring about rapid development of the storage area network (SAN) market, by increasing the capabilities and performance of storage data transmission.
		Because of the ubiquity of IP networks, iSCSI can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval.
		iSCSI is one of two main approaches to storage data transmission over IP networks; the other method, Fibre Channel over IP (FCIP), translates Fibre Channel control codes and data into IP packets for transmission between geographically distant Fibre Channel SANs.

	iSCSI: The protocol for IP/Ethernet-based storage area networking
		An iSCSI SAN can be the solution here in that it provides comparatively excellent throughput, delivers the benefits of consolidated storage and requires fewer resources overall than FC in terms of people and cost.
		This is because iSCSI storage is presented to the OS as though it is attached locally, rather than presenting it as a network share.
		And because iSCSI storage is seen at the block-level, it is possible to use an operating system’s native file system on those devices.

		The UNH iSCSI Initiator and Target are implemented as independently loadable software modules for the Linux kernel, versions 2.4.18 or later.
		It supports almost all components of the iSCSI standard, and development is underway to provide support for the few remaining components.
		This mode is used primarily for testing and to study the performance of the iSCSI protocol without the overhead of actual I/O to storage.

	ISCSI delivers storage over Ethernet
		ISCSI uses Ethernet as a transport for data from servers to storage devices or storage-area networks.
		Because iSCSI uses SCSI commands, relying on Ethernet only to transport the SCSI commands, operating systems see iSCSI-connected devices as SCSI devices and are largely unaware that the SCSI device resides across the room or across town.
		ISCSI is built using two of the most widely adopted protocols for storage (SCSI) and networking (TCP).

	iSCSI: All you need to know about iSCSI
		NFS and CIFS were designed to transfer complete files (as in NAS), while iSCSI was designed to transfer data between servers and storage systems at the block level (as in SAN), similar to how servers read and write to internal disk drives.
		The ease of use of iSCSI and the vast support from different OSâs enable the easy transfer of complete volumes from one host to the other as needed, without investing in additional infrastructure or complicated management schemes.
		iSCSI Target: The iSCSI target is the storage device itself or an appliance that controls and serves volumes or virtual volumes.

	IP Storage: A review of iSCSI, FCIP, IFCP
		The primary market driver for the development of the iSCSI protocol is to enable broader access of the large installed base of DAS over IP network infrastructures.
		A secondary driver of iSCSI is to allow other SAN architectures such as Fibre Channel to be accessed from a wide variety of hosts across IP networks.
		iSCSI enables block-level storage to be accessed from Fibre Channel SANs using IP storage routers or switches, furthering its applicability as an IP-based storage transport protocol.

	What is iSCSI? - A Word Definition From the Webopedia Computer Dictionary
		iSCSI supports a Gigabit Ethernet interface at the physical layer, which allows systems supporting iSCSI interfaces to connect directly to standard Gigabit Ethernet switches and/or IP routers.
		iSCSI is important to SAN technology because it enables a SAN to be deployed in a LAN, WAN or MAN.
		iSCSI was developed by the IETF and became an official standard in February 2003.

		ISCSI networks are also compatible with IP-based security mechanisms such as Kerberos, public-key encryption and IPsec.
		Initially, the best fit for iSCSI may be around the edges of the FC SAN, where its lower cost makes more sense.
		Where you do not need [iSCSI's] operating distances and you have already invested in FC, there is no point at this moment to switch to iSCSI.

	Storage over the Internet - iSCSI emerges
		The other approach is IP storage, known as iSCSI, which transmits native SCSI over a layer of the IP stack.
		ISCSI will let a corporate network transfer and store SCSI commands and data at any location with access to the WAN or, if transmitted over the Internet, to locations with access to the Internet.
		The storage controller then uses the iSCSI headers to send the SCSI control commands and data to the appropriate drive, which performs the functions that were requested by the original computer or application.

	Storage industry split over connections \| CNET News.com
		On the other side of the divide is iSCSI, a young technology that promises simpler networks and lower costs because it's based on the much more common Internet Protocol (IP).
		The iSCSI standard, meanwhile, is passing a critical step as companies such as Adaptec and Alacritech have begun putting finishing touches on dedicated chips that will make iSCSI fast enough to compete with Fibre Channel.
		He leaned toward iSCSI because he can extend his existing IP networks and management software while avoiding the high cost of Fibre Channel.

	iSCSI \| Homepage
		A major advantage of iSCSI over FCP is that iSCSI can run over standard, off-the-shelf network components, such as Ethernet.
		A network that incorporates iSCSI SANs need use only a single kind of network infrastructure (Ethernet) for both data and storage traffic, whereas use of FCP requires a separate type of infrastructure (Fibre Channel) and administration for the storage.
		Since iSCSI is designed to run on an IP network, it can take advantage of existing features and tools that were already developed for IP networks.
