Choice: ‘Fixed port
bond mode’ or ‘Aggregate Port bond mode’:
Fixed port bond mode

[C] Ports 1 and 3 are bonded together for the Client
Network, if this network is used.
[G] Ports 2 and 4 are bonded together for the Grid
Network
When using Fixed port bond mode, the ports can be
bonded using active-backup mode or Link Aggregation Control Protocol
mode (LACP 802.3ad).
In active-backup mode (default), only one port is
active at a time.
- If the active port fails, it’s backup port
automatically provides a failover connection.
- Port 4 provides a backup path for port 2 (Grid Network)
- Port 3 provides a backup path for port 1 (Client Network)
In LACP mode, each pair of ports forms a logical
channel between the controller and the network.
- Allows for higher throughput.
- If one port fails, the other port provides a failover
connection (throughput is reduced, but connectivity is not impacted.)
Aggregate port bond
mode

[1] All connected ports are grouped in a single LACP
bond, allowing all ports to be used for Grid Network and Client Network
traffic.
If you plan to use aggregate port bond mode:
- You must specify a unique VLAN tag for each network.
This VLAN tag will be added to each network packet to ensure that network
traffic is routed to the correct network.
- The ports must be connected to switches that can
support VLAN and LACP. If multiple switches are participating in the LACP
bond, the switches must support multi-chassis link aggregation groups (MLAG),
or equivalent.
- You must understand how to configure the switches to
use VLAN, LACP, and MLAG, or equivalent.
- If you do not want to use all four 10/25-GbE ports, you
can use one, two, or three ports. Using more than one port maximizes the
chance that some network connectivity will remain available if one of the
10/25-GbE ports fails.
Note: If you choose to use fewer than four ports, be
aware that one or more alarms will be raised in the Grid Manager after
StorageGRID Webscale is installed, indicating that cables are unplugged. You
can safely acknowledge the alarms to clear them.
