Building SANs with Brocade Fabric Switches
Format: PDF / Kindle (mobi) / ePub
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
complete Brocade team effort.We would like to acknowledge several people in particular.Without their help, dedication, and knowledge, this book would not have been possible.The thorough technical review by Viet Dao, John Gareri, Mark Murphy, Jay Rafati, Ron Totah, and Ezio Valdevit shaped our manuscripts into a book that Brocade can be proud of. John Bae, James Carpignano, Steve Daheb, Derek Granath, Jay Kidd, and Omy Shani provided several timely contributions to the content.We also incorporated
normally will constantly LIP.This essentially eliminates communication between other devices on a loop— similar to somebody’s cell phone continually ringing during a meeting. Signal retiming is the ability of hub hardware to clean up the signal received from a device. Instead of just electrically passing a signal through the port (including potential errors or noise on the line), a retimed port will take the signal and re-encode it on the wire. Any errors will be removed from the signal and noise
ports on the Fibre Channel network, effectively emulating the broadcast properties of Ethernet networks.This helps to fully support file sharing, such as NFS, bootp, ARP, ping, and other protocols on top of IP that are dependent on broadcast and that are usually not aware of the behavior of IPFC. This is a necessary part of fabric operation if you intend to send any IP frames across your network. Some HBAs do not react well to IP broadcasts, so you might need to use switch zoning to allow them to
of events in a hot-plug situation is this: an HBA fails or is otherwise showing signs of problems.Through system error logs, an administrator determines that a certain piece of hardware is at fault, and either indicates through software or through buttons or levers on the system that he or she would like to swap this HBA.This signals to driver software and to the hardware bus to stop I/O to a card and isolate the connections of that card from the remainder of the system. Usually, a light or other
that help reduce SAN management costs. Q: What kind of switch is most suited for a very large enterprise SAN? A: The Brocade SilkWorm 6400 provides 64 ports of connectivity with highavailability characteristics, making it ideal for data center environments and enterprise SAN implementations. 147 140_SANs_04 8/14/01 3:34 PM Page 148 140_SANs_05 8/14/01 3:35 PM Page 149 Chapter 5 The SAN Design Process Solutions in this chapter: ■ Looking at the Overall Lifecycle of a SAN ■
