Advanced Server Features

3Com DynamicAccess technology advanced network
software adds intelligence to the NIC to improve network
performance, management, and control. DynamicAccess
server features relieve network congestion and ensure high
performance and maximum bandwidth availability.

Load Balancing

Load balancing maximizes bandwidth at the server through
the use of multiple parallel resilient server links (RSLs) that
share the network load.
An RSL consists of two or more NICs that form a virtual
NIC. Each virtual NIC has multiple physical NICs bound to it,
forming a group. Each NIC in a group uses the same

Desktop Management Interface (DMI)
managed computers and net computers to report
details about themselves and their peripheral devices
across the network to a DMI 2.0-compliant
management application.
Remote System Alerts
a possible computer power loss or theft.
Self-healing drivers (SHDs) detect common error
conditions and correct them while maintaining server
link performance.
Load balancing groups share the network load over
resilient server links (RSLs) that keep traffic flowing even
if a NIC in a group is temporarily disconnected.
VLANs (IEEE 802.1Q multiple virtual LANs) let you divide
network segments into logical partitions that simplify
configuration changes, organize work groups efficiently,
help to control traffic, and provide extra security.
Traffic prioritization (IEEE 802.1p/Q)—Ensures that
business-critical and delay-sensitive traffic (such as
multimedia applications) has priority over normal data.
