104 CHAPTER 5: INSTALLING NETWARE CLIENT AND SERVER DRIVERS
Maintaining Groups
DynamicAccess technology server features allow you to
configure load balancing groups. The load balancing
features are described in Advanced Server Features on
page 17.
The following DynamicAccess technology server features
are available for NIC groups in NetWare:
■ load balancing
■ RSL failover
The examples in this section illustrate typical actions you
might take in the course of maintaining a DynamicAccess
server configuration under NetWare. They show how to
add NICs and groups to a server where DynamicAccess
technology server features are already installed and
configured.
Two drivers are associated with DynamicAccess technology
server features in NetWare: SE and LBRSL.
Planning the Configuration
■ Plan the cable changes required to connect each
primary NIC and all secondary NICs to the same
network segment.
■ For optimum failover performance, turn the spanning
tree feature off at switches that are connected directly
to the server. If the spanning tree feature must be
turned on, a failover may be delayed up to 30 seconds
while the switch processes the spanning tree algorithm.
■ Decide which NICs are to be part of each group. Each
group must include at least two NICs.
■ Decide whether you want to use a foreign NIC in one of
the groups.
One foreign NIC (one that is not a 3CR990 NIC) is
allowed in one group per server.
■ Decide which NIC is to be the primary NIC in
each group.
