Fabric Operating System (FOS)

Enterprise-class operating system for storage networking

Currently Viewing:

The Brocade FOS family includes a wide range of industry-leading products, including:

Directors: The Brocade X6 Director features industry-leading Gen 6 Fibre Channel that increases performance for demanding workloads across 32 Gbps line-speed links and up to 16.2 Tbps of chassis bandwidth to address next-generation I/O- and bandwidth-intensive applications.

Switches: Brocade G610 and G620 Switches are designed to meet the demands of hyper-scale virtualization, large cloud infrastructures, and growing flash-based storage environments by delivering market-leading Gen 6 Fibre Channel technology.

Embedded switches: Brocade embedded switches are designed to meet the unique and demanding requirements of the blade server market. These products can operate in Brocade Access Gateway mode, increasing scalability and simplifying management since the embedded switch does not appear as a traditional fabric switch.

Extension solutions: Brocade provides purpose-built data center extension solutions for Fibre Channel and IP storage environments. These extension solutions are designed for high-speed, secure transport of data between data centers while maintaining uptime. They enable storage and mainframe administrators to optimize and manage the use of WAN bandwidth, secure data over distance, and minimize the impact of disruptions to help ensure objectives are met.


Fabric Vision Technology:

  • Insight and IO Insight, an extension of Gen 6 Fibre Channel, provides unprecedented insight and visibility across the storage network with powerful, integrated monitoring, management, and diagnostic tools that enable organizations to Simplify monitoring, Increase operational stability and Dramatically reduce costs.


Additional RAS Features:

  • The Brocade FOS product family offers additional advanced features that help ensure the highest level of reliability, availability, and serviceability.


Management Simplicity:

  • Fabric configuration and management can become increasingly time-consuming and complex as fabric size grows. To address these challenges.


Adaptive Networking Services:

  • Server and storage consolidation increases fabric bandwidth requirements. And, as virtual servers concentrate more applications on a single server and dynamically move Virtual Machines (VMs) and their applications between physical servers, unexpected congestion can occur in the fabric.



  • Data centers have become strategic assets charged with ensuring business continuity. Consequently, fabric-assisted data protection is an important asset in keeping up with data growth and the financial and regulatory penalties incurred when data is lost or inaccessible.



  • Virtualization increases the utilization of shared resources, including servers, the SAN fabric, and storage devices.
  • Brocade Adaptive Networking services help ensure the highest utilization of shared resources by avoiding congestion and application disruption.


Data Protection:

  • Data protection has become a mission-critical requirement for next-generation data centers.
  • Brocade has more than 25 years of data center experience, and has developed an extensive suite of data protection features for access control and security.
