iSCSI Last modified: Tuesday, October 21, 2008
Pronounced eye skuzzy. Short for Internet SCSI, an IP-based standard for linking data storage devices over a network and transferring data by carrying SCSI commands over IP networks. 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. When an operating system receives a request it generates the SCSI command and then sends an IP packet over an Ethernet connection. At the receiving end, the SCSI commands are separated from the request, and the SCSI commands and data are sent to the SCSI controller and then to the SCSI storage device. iSCSI will also return a response to the request using the same protocol. 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 - What Does it Mean For Your Storage Network? This article answers the following questions: What will iSCSI mean to your storage network? What will iSCSI mean to customers who perhaps had considered storage networking to be too expensive? What will users need to implement an iSCSI based SAN? How will an iSCSI-based SAN compare in terms of performance and cost to Fibre Channel? iSCSI Review A technical explanation of how iSCSI works, including diagrams. iSCSI Storage Magazine White papers, news, links and product reviews for iSCSI technology. iSCSI: Pipe Dream or Mainstream Technology? Is iSCSI still just a pipe dream, or has it finally arrived to the status of a mainstream technology? A 2003 article from Enterprise Storage Forum. Securing iSCSI Using IPSec IP-based SANs are attractive alternatives to their more expensive and complex Fibre Channel counterparts, but securing IP communications remains a significant concern. This article examines how the IP Security Protocol (IPSec) can ensure the security of an iSCSI storage network's data.
