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.
