What is the maximum fabric size supported by the DS-6505B?

The DS-6505B supports a maximum fabric configuration of 239 switches with up to 6,000 active nodes. Certified configurations include 56 switches per fabric with a maximum of 19 hops. Exchange-based Dynamic Path Selection optimizes routing across large fabrics, ensuring efficient load balancing and performance.

Can the DS-6505B be upgraded from 12 to 24 ports without replacing hardware?

Yes. The switch ships with 12 active ports and supports upgrade to 24 ports via Ports on Demand (PoD) licensing. This enables cost-effective capacity expansion without hardware replacement, making it ideal for growing SAN environments.

What port speeds does the DS-6505B support?

The switch supports auto-sensing 2, 4, 8, and 16 Gbps Fibre Channel speeds on all ports. This backward compatibility allows mixed-speed deployments, enabling organizations to integrate legacy 2/4/8 Gbps infrastructure with modern 16 Gbps storage systems.

What is the power consumption and cooling requirement?

Maximum power consumption is 80W with all 24 ports populated at 16 Gbps SWL optics, dropping to 60W for an empty chassis. Heat dissipation reaches 338 BTU/hr at full capacity. The switch includes a single hot-swappable power supply with integrated cooling fans; optional dual redundant supplies are available.

What ISL trunking capabilities does the DS-6505B offer?

The switch supports frame-based ISL trunking with up to eight 16 Gbps ports per trunk, delivering 128 Gbps per trunk. Exchange-based load balancing with Dynamic Path Selection (DPS) automatically distributes traffic across trunks, optimizing fabric-wide performance.

What diagnostic and management features are included?

The DS-6505B includes ClearLink diagnostic ports (D_Ports) for cable/optics testing, loopback diagnostics, traffic/latency/distance analysis, flow mirroring, FCping, and frame viewer tools. Brocade Fabric Vision provides comprehensive monitoring and management, simplifying administration and reducing operational costs.

Is redundant power supply available for high-availability deployments?

Yes. The base configuration includes a single hot-swappable power supply. Optional dual redundant hot-swappable power supplies are available, eliminating single points of failure and ensuring continuous SAN availability for mission-critical storage operations.
