D-Link’s DXS-3400 Series  Top-of-Rack 10 Gigabit Stackable 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.

Feature Rich Software

The DXS-3400 Series switches include feature rich software which satisfies the needs of Small Medium  Business,  Small  Medium  Enterprise,  and  campus  users.  It  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  also  includes  an  easy-to-use  web  interface  and  an  industry  standard  CLI  for  improved management.

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-to-back  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.
