iSCSI: The Universal Storage Connection is an informative overview and in-depth guide to the emerging iSCSI standard, the technology that enables data storage, access, and management over networks, intranets, and the Internet. The iSCSI protocol reduces the total cost of ownership of shared storage solutions and enables an organization to tie together disparate systems and data, including both server class systems and laptop and desktop systems. Numerous leading technology companies, including IBM®, Cisco Systems®, and Intel®, are currently supporting iSCSI initiatives.
Written for network and data storage
professionals, this comprehensive book introduces iSCSI and
explores its growing role within the data storage industry. It
describes each element of the technology in detail—from
session establishment through error handling—and examines the
relationship between iSCSI and the SCSI protocol from which it
Specific topics discussed include:
iSCSI's use in small office, midrange, and high-end settings
TCP/IP fundamentals, and how they apply to iSCSI
The importance of data integrity
New hardware that addresses bandwidth and latency issues
iSCSI naming conventions
The establishment of a communication path between the host system and storage controller
Commands and data sequencing
Control of the flow of commands
Companion technologies, including discovery and security processes
Backup and disaster preparation
iSCSI performance issues
In addition, the book includes an explanation of the technologies that hardware vendors are implementing to permit direct memory placement of iSCSI messages without additional main processor involvement.
A helpful icon appears throughout the book, mapping out appropriate reading tracks based on your technical level.
Comprehensive, clearly written, and organized for easy access, this iSCSI handbook serves as both an excellent starting point for those involved in data storage solutions and a guide to understanding the technically detailed Internet Engineering Task Force (IETF) iSCSI Standards document.
