D-Link’s DXS-3400 Series Layer 3 Stackable 10 GbE Managed Switches are 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. 10GbE copper and fiber versions are available. The DXS-3400-24TC includes twenty (20) 10GBASE-T (RJ45) ports and four (4) 10GbE “Combo” ports (RJ45/SFP+). The DXS-3400-24SC includes twenty (20) 10GbE optical (SFP+) ports and four (4) 10GbE “Combo” ports (RJ45/SFP+).
High Availability and Flexibility
The DXS-3400 Series switches feature modular fans and power supplies 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 allows the switches to be managed from a single IP address and provides 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 application. The DXS-3400 Series switches support 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 Software Images
The DXS-3400 Series switches include the Standard Image (SI) software, and for additional functionality, they may be upgraded to the Enhanced Image (EI) software with a separately ordered license upgrade. 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 OSPFv2/v3, IPv6 Tunneling, and multicast features such as IGMP, MLD, DVMRPv3, and Multicast Source Discovery Protocol (MSDP).
This approach allows I.T. managers to deploy a lower cost L2/L2+ solution today, and upgrade to a L3 solution in the future if networking needs change and a full dynamic routing solution is required.
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 within different traffic classes. IEEE 802.1Qau (Congestion Notification) provides congestion management for data flows within network domains to avoid frame loss.
The DXS-3400 Series switches feature front-to-back airflow which optimizes air circulation inside the rack, supports hot and cold aisles in data centers, and increases energy efficiency. The switches also feature 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 slower, reducing the switch’s power consumption and noise.
