Frequently asked questions

What is the maximum aggregate bandwidth of the DS-300B?

The DS-300B delivers 408 Gb/s aggregate bandwidth calculated as 24 ports × 8.5 Gb/s line rate × 2 (full duplex). This supports concurrent bidirectional traffic across all ports at maximum 8 Gb/s speed, enabling high-performance enterprise SAN deployments.

How does Ports-on-Demand licensing work?

Ports-on-Demand allows deployment starting with 8 activated ports, expandable to 16 or 24 ports through software licensing without hardware changes. This enables cost-effective entry-level SAN deployment with non-disruptive growth as storage requirements increase.

What port speeds does the DS-300B support?

The switch auto-senses 1, 2, 4, and 8 Gb/s Fibre Channel speeds with optional fixed-speed programming. Speed matching between heterogeneous ports enables seamless integration with legacy 2/4 Gb/s and modern 8 Gb/s storage infrastructure.

What is the maximum ISL trunk bandwidth?

ISL trunking supports up to eight 8Gb/s ports per trunk, delivering 68 Gb/s aggregate bandwidth (8 ports × 8.5 Gb/s line rate). This enables high-bandwidth fabric interconnects for core-to-edge SAN architectures with exchange-based load balancing.

What are the physical dimensions and power requirements?

The DS-300B is a 1U rack-mount switch measuring 42.88 cm (W) × 4.29 cm (H) × 30.66 cm (D), weighing 4.2 kg without media. It consumes 48W nominal power (57W maximum at 24 ports 8Gb/s) with 85-262 VAC input at 47-63 Hz.

Does the DS-300B support redundancy?

Yes, the switch includes redundant cooling and redundant power supplies for high availability. It operates reliably in 0-40°C environments with 10-85% non-condensing humidity, supporting mission-critical SAN deployments.

What management capabilities are included?

Management features include Telnet, HTTP, SNMPv3 (FE MIB, FC Management MIB), EZSwitchSetup wizard, Web Tools, and EMC Connectrix Manager integration. Auditing, Syslog, and change management tracking enable comprehensive SAN monitoring and troubleshooting.
