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 groups share the network load over
resilient server links (RSLs) that keep traffic flowing even
if a NIC in a group is temporarily disconnected.
■ Self-Healing Drivers (SHDs) detect common error
conditions and correct them while maintaining server link
performance.
■ Failover fault tolerance provides a backup solution in
the event of a NIC failure.
■ 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.
