• Split-LAG with a single logical switch
Note: The serv
ers are always in LACP Active mode while the switches can be
configured in active or passive LACP mode.
Split-LAG with Layer-2 redundancy
When LACP is enabled, it is possible to have a scenario where a pair of
clustered NAS servers are connected to a pair of switches configured with one
link aggregation (over two file-serving interfaces) as shown in the example
below:
This scenario provides basic Layer-2 redundancy on the NAS servers.
Note: Static aggregation is not supported in a split
-LAG scenario.
Split-LAG with Layer-2 redundancy and increased bandwidth
This scenario includes a link aggregation o
ver four file-serving interfaces for
increased bandwidth and increased standby links as shown in the example
below:
