D-Link's DXS-3400 Series Lite 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.
High Availability and Flexibility
The DGS-3630 Series switches support stacking technology, which combines multiple switches to form a single physical or virtual stack. This increases redundancy over multiple physical units, simplifies management, and provides a single IP address to manage all members in the stack. Up to 9 switches can be stacked using Direct Attach Copper (DAC) or fiber optic cables to make up to 432 Gigabit Ethernet ports available, allowing switching capacity to be increased with demand. 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. There are 3 modes: IP Mode, LAN Mode, and L2 VPN Mode, which modify the size of the Layer 2 and 3 tables for optimum efficiency.
Feature Rich Software
The DXS-3400 Series switches include feature rich software which satisfies the needs of Small/Medium Business (SMB), Small/Medium Enterprise (SME), and Campus users. This software supports a wide range of Layer 2 and 3 functions such as VLANs, inter-VLAN routing, multicasting, Quality of Service (QoS), Virtual Router Redundancy Protocol (VRRP), Routing Information Protocol (RIP)v1/2, Next Generation RIP (RIPng), Policy-Based Routing (PBR), and security features. The DXS-3400 Series switches also include an easy-to-use web interface and an industry standard CLI for improved management.
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 frame loss.
