Load Balance

Load balance is a protocol-specific scheme. The levels of support for IP, IPX, and other protocols are listed below.

Protocol

Load Balancing

IP

Yes

IPX

Yes*

Yes**

Other protocols

No

Yes**

*Only outbound load-balancing for IPX (on NetWare only). **For 3Com NICs.

Load balance mode works with all Ethernet switches without configuring the switch ports to any special trunking mode. Only IP traffic will be load-balanced in both inbound and outbound directions. IPX traffic will be load-balanced in the outbound direction only. Other protocol packets will be sent and received through one primary NIC only. Failover for non-IP traffic is supported using 3Com,Broadcom,Alteon, and Intel NICs. The generic trunking mode requires the Ethernet switch to support some form of port trunking mode (for example, Cisco Systems Gigabit EtherChannel or other switch vendors’ link aggregation mode). This mode is protocol-independent and all traffic should be load- balanced and fault-tolerant.

Advanced Server Features for Windows 2000

The following options are supported under Windows 2000 Server operating systems (Server, Advanced Server, Datacenter Server). See “Windows 2000 Driver Setup” on page 25 for additional information.

Failover and Load Balance

Adapter teaming for failover (heterogeneous support for 3Com 10/100 server NICs, Alteon AceNIC, released Intel 10/100 server NICs, released Intel 1000BaseSX server NICs, and Intel 82559 LAN on Motherboard [LOM])

Load balance

Generic Link Aggregation (GEC/FEC, open trunk)

Link aggregation (IEEE 802.3ad) static implementation only

Virtual LAN (VLANs)

Up to 64 VLANs per team using IEEE 802.1Q-1988 tagging

Offloading

IP, TCP/UDP checksum

Support for segmentation of large TCP packets

Jumbo frames (9K)

Power Management

Remote Wake Up (magic packet, specific pattern)

NOTE: Wake-on-LAN (WOL) is not supported with the fiber version of the Gigabit Server NIC (3C996-SX). WOL must be disabled when using the fiber Gigabit Server NIC.
