Heterogeneous Fibre Channel Network At Networld+Interop Business Wire - April 29, 1998 11:13 %BROCADE-COMMUNICATIONS %CALIFORNIA %NEVADA %COMPUTERS %ELECTRONICS %COMED %ADVISORY %TRADESHOW V%BW P%BW -------------------------------------------------------------------------------- --(BUSINESS WIRE)-- WHERE: Brocade booth No. 8234, Networld+Interop May 5-7 in Las Vegas WHAT: Brocade will demonstrate for the first time its exclusive ZONING service, enabling a heterogeneous environment by delineating eight different zones for simultaneous UNIX, NT and SGI system solutions on the same Fabric. Brocade ZONING enables the configuration of Fabric-connected devices on a Server-Storage Area Network (SAN) into logical subsets within the physical Fabric. The Brocade demonstration will feature three interconnected Brocade SilkWorm family switches in a true network of servers and storage. The Brocade Fabric clearly demonstrates the increased scalability and flexibility that a Fibre Channel switch can provide over hubs, without sacrificing bandwidth performance. No other Fibre Channel switch vendor can interconnect, or cascade, switches to build a network Fabric. In total, the Brocade Fabric demonstration will include over 1/2 terabyte of storage running on arbitrated loops connected to SilkWorm FL_Ports. Additionally, Brocade will demonstrate over a gigabyte per second of aggregate throughput on the three-switch Fabric. Highlights of the Brocade ZONING service to be demonstrated include: -- ZONE 1 -- This zone demonstrates the scalable bandwidth that the Brocade Fabric can manage high throughput-intensive applications. Four SGI 02 workstations, each using a Prisa Networks' PCI Fibre Channel adapter (for IP and SCSI), will each access and playback uncompressed video clips through independent streams from two Unisys JBOD's (Just a Bunch of Disks). Total aggregate throughput on the switch for all four videos will be up to 240MB/sec. -- ZONES 3, 4, AND 5 -- These three zones demonstrate the ability of the Fabric administrator to segregate UNIX and NT systems, preventing access to the others' disk while allowing them to share the same tape library for disk benchmarking and backup. A Sun workstation with a Jaycor Networks SBus adapter card, and an Intel-based NT workstation with an Emulex PCI adapter card, will occupy zones 3 and 5, each with their own CLARiiON JBOD. Additionally, both the Sun and NT systems are included in zone 4 with an Exabyte tape library connected through a Crossroads Crosspoint Fibre Channel bridge/router. Intelliguard software arbitrates/controls the backup process, tracking and scheduling the files to be saved from each system. -- ZONES 6 AND 7 -- These two zones demonstrate the ability of the Fabric administrator to divide a single storage array into two different zones. Zones 6 and 7 each include an NT workstation with an Interphase PCI adapter card (for both IP and SCSI). The two zones share a Sun A5000 disk array, with each NT system zoned to access half of the array (configured as two JBODs, seven drives each). Brocade will also demonstrate, and allow show attendees to surf the company's new WEB TOOLS, another Brocade Fibre Channel network exclusive feature. Brocade WEB TOOLS include a graphical user interface (GUI), as well as an "Expert Administrator" function that automatically pops up a dialog box alerting users to problems and providing a solution diagnosis.
