Fibre Channel
Brocade's first Fibre Channel switch SilkWorm 1000 (SW1000) (released in 1997) was based on the "Stitch" 1 Gbit/s ASIC and its own VxWorks-based firmware (Fabric OS or FOS). SilkWorm eventually came to be a long-lived marketing designation for an entire line of products, with the first product being retro-named the SilkWorm 1000 (SW1000) to distinguish it from subsequent platforms. Bruce Bergman was the CEO during most of this period. Product names were generally puns on various kinds of woven fabric, since a switched Fibre Channel network is also called a "fabric". The SilkWorm 1000 series included the SilkWorm I and II launched in 1997 with 16 ports. In 1998, the SilkWorm Express launched with 8 ports.
In 1998, Gregory Reyes joined the company as CEO. Between 1999 and 2000, Brocade launched several 1 Gbit/s switches including the SilkWorm 2800 (16-ports), SilkWorm 2400 (8-ports), SilkWorm 2250 (16-ports) and the SilkWorm 2050 (8-ports) based on the Loom ASIC. In 2001, Brocade released the SilkWorm 6400, which was designated a "director" similarly[5] to IBM ESCON directors already well-established[6] in the mainframe computer market. The term "director" became universally used for more expensive FC switches.[7]
From 2001 to 2003, Brocade released switches based on its third generation ASIC, "BLOOM" (Big LOOM). BLOOM introduced increased throughput of 2 Gbit/s. Between 2001-2002 the SilkWorm 3800 (16-ports) and SilkWorm 3200 (8-ports), and SilkWorm 3900 (32-ports) were launched. Brocade integrated BLOOM into its first "pure" director, the SilkWorm 12000, in April 2002. The director offered up to 128 ports in two 64-port pseudo-switches (domains). The 12000 represented several internal architecture and technical changes besides the new ASIC: it had an upgraded control processor architecture (Intel i960 moved to PowerPC 405GP), changed the embedded operating system (FOS v4.0 migrated from Wind River Systems VxWorks to MontaVista Linux), and introduced the backplane architecture (hierarchical PCI buses with replaceable blades attached to a backplane). The Bloom ASIC also introduced a notable capability of frame-level Fibre Channel trunking, which provided high throughput with load balancing across multiple cables. It needed to be implemented in the ASIC hardware to ensure in-order delivery of frames. Also, hot firmware upgrade was introduced with FOS v4.1 in October 2003.
At the time, Brocade's main rival, McDATA, held over 90% market share in director segment, owing to a strong position first in the ESCON market, and then in the FICON market. The SilkWorm 12000 director gained over one-third of the market share after its release in 2002. Brocade added mainframe customers with FICON and FICON CUP support on the SilkWorm 12000.
In 2004, the BLOOM II improved on the previous ASIC design by reducing its power consumption and die size, while maintaining 2 Gbit/s technology. New switches were launched including the SilkWorm 3850 (16-ports) and SilkWorm 3250 (8-ports). BLOOM II also powered Brocade's second-generation director, the SilkWorm 24000. Still a 128-port design, it was the first one which could operate as a single 128-port switch (a single domain). The new director also used approximately two thirds less power than its predecessor. Brocade also introduced its first multiprotocol Fibre Channel router, the SilkWorm 7420. Brocade also acquired Rhapsody Networks (a SAN virtualization startup company). This was also the time frame in which Brocade first entered into the embedded switch market, delivering multiple switches physically integrated into other vendors' hardware, such as storage controllers and blade server chassis.
2004 also saw the introduction of 4 Gbit/s Condor-based platforms. Between 2004 and 2006, Brocade launched several switches including the 4900 (64-ports) 4100 (32-ports), and 200E (16-ports). The 384-port 48000 director was launched in 2005. In 2006, the second generation multiprotocol Fibre Channel router 7500 switch and FR4-18i blade for the 48000 director were launched.
In January 2008 Brocade launched the 384-port 8 Gbit/s DCX Backbone.[8]
In May 2008, Brocade unveiled 3 new 8 Gbit/s switches: 24-port 300 switch, 40-port 5100 switch and the 80-port 5300 switch.[9]
In January 2009, Brocade launched the 192-port 8 Gbit/s DCX-4S Backbone.[10]
In September 2009, Brocade launched the Brocade 7800 Extension Switch and the FX8-24 Extension Blade for the DCX Backbone family for extending SANs over FCIP (Fibre Channel over IP). They also launched the Brocade 8000 Switch and the FCOE 10-24 blade for the DCX Backbone family for FCoE (Fibre Channel over Ethernet) SAN connectivity.[11]
In late 2010 Brocade introduced Virtual Cluster Switching (VCS) on the VDX[12] ultra-low-latency data center switch product line. These are DCB/CEE- and TRILL-based switches, eliminating the need for Spanning Tree Protocol, and supporting multi-hop Fibre Channel over Ethernet (FCoE) and self-trunking.[13]
In May 2011,[14] Brocade launched the industry's first "Gen 5 Fibre Channel" (16 Gbit/s) SAN platform family including the Brocade DCX 8510 Backbone, 6510 switch and 1860 Fabric Adapter. The Brocade DCX 8510 is available in 8-slot or 4-slot chassis models supporting up to 384 16 Gbit/s ports at line-rate speeds and 8.2 terabits per second (Tbit/s) of chassis bandwidth. It includes optical UltraScale inter-chassis links (ICLs) which simplify scale-out design for multi-chassis architectures. The Brocade 6510 switch is a 48-port 16 Gbit/s switch designed for virtualized applications and high-performance storage including SSD arrays. Brocade also introduced the 1860 Fabric Adapter, the industry's first adapter which includes AnyIO 16 Gbit/s FC HBA, 10GbE CNA, and 10GbE NIC functionality on the same card.
In April 2012, Brocade launched the Gen 5 (16 Gbit/s) 6505 switch (24-port) entry-level switch.
In March 2013, Brocade launched the Gen 5 (16 Gbit/s) 6520 96-port Fibre Channel high-density switch and announced Brocade Fabric Vision technology. Brocade Fabric Vision technology introduces advanced diagnostics, monitoring, and management capabilities through a combination of ASIC, FOS, and Brocade Network Advisor. New features include Brocade Monitoring and Alerting Policy Suite (MAPS) for fabric-wide threshold configuration and monitoring and Brocade Flow Vision for data flow monitoring and analysis.
In October 2014, Brocade launched the Gen 5 (16 Gbit/s) 7840 extension switch and the FC16-64 64-port blade for the DCX 8510.[15]
In March 2016,[16] Brocade launched the G620 switch, its first Gen 6 (32 Gbit/s) Fibre Channel product.
In July 2016, Brocade launched the Gen 6 (32 Gbit/s) X6 Director with 4 slots (192 or 256-ports) or 8 slots (382 or 512-ports) and SX6 extension blade.[17]
