Course Description / Overview / Expected Outcome:

A group of students was asked recently to define a "SAN." Some replies included "storage area networks," "server area networks," "system area networks" and the instructor's favorite, "The latest thing to sell!" SAN is all of these things and more. This course takes a top-down approach in examining the information flow requirements levied on a Storage Network and how various technologies meet those requirements. It identifies why organizations are moving toward NAS and SAN. It provides a comprehensive technical examination of Fibre channel, SCSI and IP protocols, along with the role they play in a Storage Network. It compares SAN technologies with network technologies including ESCON, Gigabit Ethernet, ATM, and other LAN and WAN physical transports. The course examines the practical problems faced in the heterogeneous world where the "any to any" connectivity provided by SANs can present more problems than it solves. It identifies the techniques used to overcome these problems through the use of volume management, storage resource security and persistent binding. The course identifies the components and products that make up a NAS or SAN, examines the design and performance aspects of a SAN, and finally explores where Storage Networks are headed over the next few years.

Course Objectives:

Examine approaches to the practical problems faced in homogeneous and heterogeneous world where the “any to any” connectivity provided by SANs can present just as many problems as it solves.

Examine the Storage Solutions including virtualization, data sharing, high availability and information lifecycle management.

Explore the many topologies and the underlying technologies and protocols that can be used in storage networks including Point-to-Point, Arbitrated Loop and Switched Fabric and the trade offs in cost/benefit where these topologies can be applied today.

Demystify the controversy surrounding Storage Networking’s protocol wars between Fibre Channel and IP-based storage and finally understand the differences between them and the vendor products.
