Brocade 6520 Switch

Build an agile network with a powerful, scalable enterprise SAN switch

Currently Viewing:

Tackle the dynamic and often unpredictable workloads that come with large and growing environments with the Brocade 6520 Switch’s high throughput and optimum bandwidth utilization. The Brocade 6520 Switch is a high-density building block for increased scalability to support growth, demanding workloads, and data center consolidation.

Build a network that moves as fast as your business:

Enterprise data centers must keep pace with increasingly virtualized workloads and cloud infrastructure. The Brocade 6520 Switch supports rapid growth, data center consolidation, and delivers up to 16 Gbps performance in a 2U form factor.

Get the performance you need and the reliability you trust:

Virtualization and the cloud can create an unpredictable environment. Tip the odds in your favor with throughput and bandwidth utilization that eliminates bottlenecks. The Brocade 6520 Switch offers 40 percent higher performance than 10 GbE alternatives. Simplified management through Brocade Fabric Vision helps ensure non-stop operations.

Optimize storage performance and diagnostic capabilities:

As your data center expands and becomes more complicated, you need powerful SAN switching capabilities and network analytics more than ever. The Brocade 6520 Switch combines Gen 5 Fibre Channel performance with automated monitoring and diagnostics tools to simplify SAN management.
