Network Adapter Teaming

Network adapter teaming allows the system to use the combined throughput of multiple network ports in parallel to increase

performance or to provide fault tolerance. Network adapter teaming on your NAS system supports the following technologies:

Adaptive Load Balancing (ALB)

Adapter Fault Tolerance (AFT)

Link Aggregation

Fast EtherChannel (FEC)

IEEE 802.3ad

NOTE:

When creating or removing network adapter teams, the IP address of the NAS system's LAN connections changes.

To prevent disconnection from the NAS system during team configuration, connect a keyboard, monitor, and mouse to

the NAS system when creating or removing teams. See "

Configuring Your System Using a Keyboard, Monitor, and Mouse

"

in "Initial Configuration" before configuring your teams.

Adaptive Load Balancing

Adaptive Load Balancing (ALB) is a simple and efficient method for increasing the NAS system's network transmission

throughput. The ALB software continuously analyzes transmission loading on each adapter and balances the load across the

teamed ports as needed. Adapter teams configured for ALB also provide the benefits of adapter fault tolerance. To use ALB, the

Ethernet ports on the NAS system must be linked to the same Ethernet switch.

Adapter Fault Tolerance

Adapter Fault Tolerance (AFT) provides the safety of an additional backup link between the NAS system and the hub or switch. If

a hub, switch port, cable, or Ethernet port fails, you can maintain uninterrupted network performance. AFT is implemented with a

primary adapter and a backup, or secondary, adapter. If the link to the primary adapter fails, the link to the secondary adapter

automatically takes over.

Link Aggregation

Link aggregation is a performance technology developed by Intel® and others to increase a system's network throughput. Unlike

ALB, link aggregation can be configured to increase both transmission and reception channels between your system and switch.

Link aggregation works only with compatible Intel switches. To use link aggregation, the Ethernet ports of the NAS system must

be linked to the same Intel Ethernet switch.
