xStack DES-3800 Series
The DES-3800 series is a member of the D-Link xStack switch family. xStack is a complete family of
stackable devices that ranges from edge 10/100Mbps switches to core Gigabit switches. xStack
provides unsurpassed performance, fault tolerance, scalable flexibility, robust security, standard-based
interoperability and an impressive support for 10Gigabit technology to future-proof departmental and
enterprise network deployments with an easy migration path.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format,
and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a
tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase
over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments,
Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment
in hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the
network bottlenecks that frequently develop as computers and their busses get faster and more users
using applications that generate more traffic. Upgrading key components, such as your backbone and
servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed
up the traffic between your sub networks.
Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex
imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster
than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC's are able to perform 10 times the
number of operations in the same amount of time.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective
method to take advantage of today and tomorrow's rapidly improving switching and routing inter-
networking technologies.
