The Brocade® 4100 is a high-performance, high-availability Fibre Channel switch designed for rapidly growing storage requirements in mission-critical environments. With a flexible architecture that supports 1, 2, and 4Gbit/sec technology with 16, 24, or 32 ports in a 1U package, the Brocade 4100 provides excellent value at an affordable price point. As a result, even small organizations can achieve the levels of performance and availability typically attainable only by larger enterprises.

The Brocade 4100 provides low-cost access to industry-leading SAN technology as well as support for “pay-as-you-grow” scalability with Ports on Demand. Because it is fully compatible with previous 1 and 2Gbit/sec devices, it protects existing technology investments while providing a strategic solution for the future.

These capabilities help make the Brocade 4100 ideal for branch offices and departments in large enterprises as well as for midsized organizations. It can be used as the foundation of small standalone SANs or as an edge switch in larger core-to-edge SAN infrastructures for enterprise-class applications such as ERP, MRP, data warehousing, billing, and e-mail.

The Brocade 4100 provides best-in-class performance for midrange SAN switches to support mission-critical applications. It features a non-blocking architecture with as many as 32 ports concurrently active at 4Gbit/sec full duplex to provide an aggregate bandwidth of 256Gbit/sec.
