D-Link xStack Switch Series: Meeting the Need at the Edge of the Network 7
D-Link Systems, Inc.
October 2004
Complete Solution for Mid-Sized Businesses & Enterprises
Whether you need to bring Gigabit or just conventional 10/100Mbps speed to your organization's
desktops, D-Link's xStack Series has the right solution with the right port types, port densities,
and uplinks to match your requirements. xStack Switches support up to 16,000 MAC addresses,
4,000 Layer 3 forwarding database in hardware, or 64,000 routing table entries making this an
ideal switch for both wiring closet implementations and enterprise branch offices. Even as the
customer’s network grows, the large table sizes supported in xStack Switches make them an
excellent long-term solution more than capable of supporting growth in the network. With
industry-leading scalability and flexibility, each xStack 10/100/1000Mbps Gigabit switch may be
joined in any combination to evolve with your network needs.
Industry Leading 10/100/1000 Scalability
The xStack Series delivers industry-leading 10/100/1000 density, scalability, and port flexibility,
which allows customers to easily expand their network and make the most efficient use of
available rack space. At just 1.75” (1 rack unit), one xStack switch can provide up to 48 Gigabit
ports per switch. This gives you up to 312 Gigabit ports per stack in the star-stacking
architecture, or a of maximum 384 Gigabit ports in a ring-stacking architecture. This high port
density allows xStack Switches to be deployed either as a core switch or as an easily expandable
stack for Gigabit-to-the-desktop applications. xStack’s high performance switching architectures
will continue to be a critical edge solution in the customer’s network for years to come.
10-Gigabit Ethernet at the Edge–When You Need It
D-Link's xStack Series provides 10-Gigabit uplinks for transmission at up to 10 times the speed
of a 1-Gigabit port, up to 20,000Mbps in the full-duplex mode. 10-Gigabit uplinks means that the
edge switch uplink capacity can grow as the end user’s bandwidth demands increase.
Based on a modular design, an optional 10-Gigabit “daughter card” can be added to the xStack
DXS-3350SR or DXS-3326GSR switch to deliver immediate support for two 10-Gigabit XFP
transceivers. This advanced design enables the user to easily upgrade the xStack DXS-3350SR or
DXS-3326GSR for multiple 10-Gigabit uplinks when increased capacity is required.
Non-blocking Switching Capacity—Up to 176Gbps
The xStack Series delivers industry-leading switch fabric and throughput performance giving
users the bandwidth their applications require. The xStack 48-port DXS-3350SR has a 176Gbps
switching capacity that is able to process up to 131 million packets per second, making it the
industry’s highest performance fixed configuration edge switch available. This industry-leading
performance ensures that the xStack switches will have the capacity to support ever-growing end
user bandwidth requirements.
Voice-Video-Data Convergence
Many customers are starting to reduce their overall networking expenditures by converging their
voice-video-data networks into a single network, and the xStack Series is an ideal solution for
this convergence. The xStack Series supports up to 8 queues on every port to classify and
prioritize traffic to ensure that high priority traffic, such as voice and video traffic, get the
required bandwidth when it is needed.
