Teaming Concepts
The concept of grouping multiple physical devices to provide fault tolerance and
load balancing is not new; it has been around for years. Storage devices use
RAID technology to group individual hard drives. Switch ports can be grouped
together using technologies such as Cisco Gigabit EtherChannel, IEEE 802.3ad
Link Aggregation, Bay Network Multilink Trunking, and Extreme Network Load
Sharing. Network interfaces on servers can be grouped together into a team of
physical ports called a virtual adapter.

Smart Load Balancing™ and
Failover
Switch-independent failover type of team in which the
primary team members handle all incoming and outgo-
ing traffic while the standby team member (if present) is
idle until a failover event (for example, loss of link
occurs). The intermediate NIC teaming driver (QLASP)
manages incoming/outgoing traffic.
Smart Load Balancing (SLB)
Switch-independent load balancing and failover type of
team, in which the intermediate driver manages outgo-
ing/incoming traffic.
