The first book to focus on Brocade products - an inovative tecnology company to watch out for!

Brocade Switches provide the intelligent architecture that connects Storage Area Networks (SANs) to Local Area Networks and Wide Area Networks. Brocade switches provide the same functionality to Storage Area Networks as Cisco switches provide to the Internet - Brocade Communications, Inc is the dominant company in this rapidly expanding market.

Building SANs with Brocade Fibre Channel Fabric Switches is written for system administrators who are designing, building, and maintaining Storage Area Networks with Brocade fibre switches. The book provides the reader with all of the techniques necessary to integrate fibre-based switches with an IP-based network.

The first vendor-specific book on configuring industry standard technologies
Practical approach; competitive books are mostly theoretical
IT Professionals must know how to design and build a SAN. Often over 50% of IT budgets are devoted to storage. Fibre-switched SANs are the market standard












clustering techniques (running many, coordinated servers in tandem to distribute processing) to attempt to get past the problems of limited CPU speeds and server scalability. However, clustering techniques rely on 140_SANs_01 8/14/01 1:32 PM Page 15 Introduction to SANs • Chapter 1 the latency of a network to determine what types of scaling processing are available.With most Ethernet networks comes a negative scaling effect by adding clustered servers—adding more servers allows less and

and usually include intelligence to handle the difficulties of managing Loop Initialization Primitive (LIP) conditions and loop bring up. LIPs are part of a loop initialization process and are expected in a healthy and normal loop. However, certain conditions inherent to loops create scenarios where LIPs cause an interruption to I/O or prevent devices from effectively communicating on the loop. Advanced managed hubs also avoid the problems of simple electrical hubs by isolating initiators.

core fabric switches. Features of Fibre Channel Switches Fibre Channel switches provide many different features, including support for GBICs, redundant fans and power supplies, zoning, loop operation, and multiple interfaces for management. Each of these features adds to the overall operation of your switched network and understanding the benefits and advantages of each can help you design a robust and scalable SAN.This section covers the major features of Fibre Channel switches, describes what

traffic necessary to keep your network up and running. There are additional services defined in the Fibre Channel standards that are not necessarily supported by all, or even any, switches. For example, the Time Server is not yet supported on any switching platform that we know of, but it is defined as a standard. If you or the management software you buy requires the additional services, you should ensure that the switch you buy supports or can enable those services. For example,VERITAS SANPoint

network. Serial Port The most basic management interface for Fibre Channel switches and other equipment is the serial port. A standard, RS232-based port is generally available on Fibre Channel switch equipment that allows command-line interaction with different configuration options. Telnet Telnet is the standard IP networking ability to log in to a piece of equipment through a telnet interface from any host server attached on Ethernet, or even in-band through Fibre Channel itself (Figure
