What port speeds does the DS-300B-8 support?

The switch features 8 active universal ports with auto-sensing of 1, 2, 4, and 8 Gb/s speeds, optionally programmable to fixed speeds. It provides full line-speed switching at 2.125, 4.25, and 8.50 Gb/s full duplex, ensuring compatibility with legacy and modern FC devices in SAN fabrics.

How can I expand the number of ports?

Starts with 8 active ports, expandable to 16 or 24 ports using Ports-on-Demand licenses. This pay-as-you-grow model allows matching capacity to storage demands without replacing the switch, ideal for evolving enterprise SANs.

What is the maximum bandwidth and latency?

Offers 408 Gb/s aggregate bandwidth at full 24 ports (24 x 8.5 Gb/s x 2 duplex). ISL trunking reaches 68 Gb/s per trunk with up to eight ports. Maximum fabric latency is 700 ns with no contention via cut-through routing at 8 Gb/s.

What management options are available?

Includes an Ethernet management port, Connectrix Manager software for monitoring/reporting/troubleshooting, and EZSwitchSetup wizard for simplified initial deployment. Supports Telnet, HTTP, SNMPv1/v3, and SMI-S compliance for integrated fabric management.

What physical and power specs should I know?

1U rack-mount form factor for 19-inch EIA cabinets, with one fixed power supply (48-57W consumption) and three built-in fans in 2-1 redundant configuration sustaining single fan failure. Dimensions: 42.88 x 4.29 x 30.66 cm, weight 4.2 kg without SFPs.

Which Fibre Channel standards are supported?

Complies with FC-PH, FC-PH-2, FC-PH-3, FC-GS-2, FC-FLA, FC-FG, FC-SW3. Supports Class 2, 3, F services, unicast/multicast/broadcast traffic, and fabric topologies up to 56 domains/19 hops in single FOS fabric.
