D-Link DXS-3400-24SC/SI DXS-3400 Series Lite Layer 3 Stackable 10 GbE Managed Switches

DXS-3400 Series Lite Layer 3 Stackable 10 GbE Managed Switches

D-Link’s DXS-3400 Series Lite Layer 3 Stackable 10 GbE Managed Switches are new, compact, high-performance switches that feature wire-speed 10-Gigabit Ethernet switching, routing, and ultra-low latency. The 1U height and high port density make the DXS-3400 Series suitable for enterprise and campus environments where space is at a premium. The DXS-3400 Series switches also include 20 10GBASE-T or 10G SFP+ ports and 4 10GBASE-T/SFP+ combo ports, making them suitable for datacenter, core, and distribution applications.

High Availability and Flexibility

The DXS-3400 Series switches feature a modular fan and power supply design for a high availability architecture. The hot-swappable design means that fans and power supplies can be replaced without affecting switch operation. Physical and virtual switch stacking allow the switches to be managed from a single IP address and provide redundancy for connected devices. The Switch Resource Management (SRM) feature allows the hardware table size to be changed, so that switch functions can be optimized based on the use of the switch. The DXS-3400 Series switches come with 3 modes: IP Mode, LAN Mode, and L2 VPN Mode, which modify the size of the Layer 2 and 3 tables for optimum efficiency.

Standard and Enhanced Images

The DXS-3400 Series is designed for use with two different software images: the Standard Image (SI) and the Enhanced Image (EI). The Standard Image provides core SMB and SME functionality, such as L2 switching, entry-level routing, L2 multicast, advanced Quality of Service (QoS), Operations, Administration, and Maintenance (OAM), and robust security features. The Enhanced Image supports all Standard Image features, in addition to advanced L3 routing for enterprise integration, including OSPF versions 1 and 2, IPv6 Tunneling, and multicast features such as IGMP, MLD, DVMRPv3, and Multicast Source Discovery Protocol (MSDP). With multiple software images, only the required features need to be purchased, providing a flexible approach to software licensing.

Lossless Ethernet

Data Center Bridging (DCB) is an essential set of enhancements to Ethernet for networking in data center environments. The DXS-3400 Series switches support several core components of Data Center Bridging (DCB) such as IEEE 802.1Qbb, IEEE 802.1Qaz, and IEEE 802.1Qau. IEEE 802.1Qbb (Priority-based Flow Control) provides flow control on specific priority to ensure there is no data-loss during network congestion. IEEE 802.1Qaz (Enhanced Transmission Selection) manages the allocation of bandwidth amongst different traffic classes. IEEE 802.1Qau (Congestion Notification) provides congestion management for data flows within network domains to avoid congestion.

Energy Efficient

The DXS-3400 Series switches feature front-to-back airflow which facilitates the building of energy-efficient data centers. The front-to-back airflow optimizes air circulation inside the rack, allowing hot and cold isles in data centers, increasing energy efficiency in comparison to a mix of front-toback and side-to-side airflow. The switches also feature in-built smart fans; internal heat sensors monitor and detect temperature changes, and react accordingly by utilizing different fan speeds for different temperatures. At lower temperatures, the fans will run more slowly, reducing the switch’s power consumption and noise.
