Dellemc Fiber Optic Switch

Dell EMC fiber optic switches provide high-performance, scalable connectivity for data centers, supporting 10GbE to 64G Fibre Channel with flexible port configurations and advanced management features.

Overview of Dell EMC Fiber Optic Switches

Dell EM

C offers a range of fiber optic switches designed for enterprise and data center environments, including the S4100-ON series, S4148U, and Connectrix B-Series. These switches support high-speed Ethernet and Fibre Channel connectivity, enabling dense, low-latency networking for storage and compute workloads. S4100-ON SeriesPort Options: Up to 48 ports of 10GbE or 10GBaseT, 2 ports of 40GbE, and 4 ports of 100GbE in a 1RU form factor; S4112-ON supports up to 12 ports of 10GbE and 3 ports of 100GbE.

Features: Supports L2/L3 VXLAN gateway, priority-based flow control (PFC), data center bridge exchange (DCBX), and enhanced transmission selection (ETS) for converged data center environments. Flexibility: Compatible with Dell SmartFabric OS10 or third-party network operating systems; supports multirate speeds for simplified migration to 100Gbps. S4148UFibre Channel Deployment: Supports native Fibre Channel fabrics with zoning and zoneset configuration for secure storage connectivity.

Use Case: Ideal for storage fabrics requiring high-speed, low-latency connections between servers and storage arrays.

Connectrix B-

Series (DS-7730B, DS-7720B, DS-7710B)Port Density: DS-7730B offers 96 64G SFP+ ports and 16 SFP-DD ports (32 ports per SFP-DD), enabling high-scale fabrics in a compact 2U design. Scalability: Supports Ports on Demand (PoD) to expand from 48 to 128 ports cost-effectively. Performance: Provides 64G Fibre Channel with 50% lower latency compared to previous generations, optimized for NVMe storage and high-transaction workloads.

Transceivers and Connectivity

Dell EM

C switches use SFP, SFP+, SFP28, QSFP+, and SFP-DD transceivers for fiber connectivity, supporting short, long, and extended reach options. For example: 10GbE SFP+: Short-reach (SR), long-reach (LR), and extended reach (ER/ZR) with duplex LC connectors. 100GbE QSFP+: Can be broken out into four 25GbE lanes using active optical or passive copper breakout cables.

Diagnostics: Many transceivers provide enhanced digital monitoring for temperature, optical power, and supply voltage.

Key Benefits

High Performance: Low-latency, non-blocking architecture suitable for high-transaction and NVMe storage workloads. Scalability: Modular and fixed-port options with PoD and SFP-DD support for growing data center needs. Flexibility: Supports multiple network operating systems and multirate speeds for seamless upgrades.

Advanced Management: Fibre Channel zoning, VXLAN gateway, and DCB features for optimized storage and compute traffic.
