Future-Proof Your SAN with the DB820S and DB720S Switches

What’s inside?

The Brocade 6510 (Gen 5) switch is now well beyond its Fabric OS® End-of-Availability date and has officially reached End-of-Support – meaning no more bug fixes, no more security patches, and no TAC assistance if it remains in your fabric. As threats evolve and workloads intensify, running unpatched, aging infrastructure exposes your SAN to rising security risks, hardware failures, and performance bottlenecks.

This guide outlines why it’s critical to replace Gen 5 and Gen 6 switches and how upgrading to the Lenovo DB820S (Gen 8) or DB720S (Gen 7) can future-proof your SAN. You’ll learn:

• What FOS EOA and EOS mean for security, stability, and support
• How outdated switches create compatibility issues, congestion, and vulnerability
• Why hardware aging increases the likelihood of downtime and data exposure
• How Lenovo DB820S and DB720S deliver quantum-safe security, higher bandwidth, and intelligent, autonomous SAN operations

Discover how modern Lenovo Gen 7 and Gen 8 platforms provide the performance, resilience, and protection your data center needs, today and for the future.
