Callout Which ports are bonded
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, its
backup port automatically provides a failover connection. Port 4 provides a backup path for port 2
(Grid Network), and 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,
allowing for higher throughput. If one port fails, the other port provides a failover connection.
Throughput is reduced, but connectivity is not impacted.
Note: If you do not need redundant connections, you can use only one port for each network.
However, be aware that an alarm will be raised in the Grid Management Interface after
StorageGRID Webscale is installed, indicating that a cable is unplugged. You can safely
acknowledge this alarm to clear it.
Aggregate port bond mode
Aggregate port bond mode significantly increases the throughout for each StorageGRID Webscale
network and provides additional failover paths.
Callout Which ports are bonded
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 Management Interface after StorageGRID Webscale is installed, indicating that cables
are unplugged. You can safely acknowledge the alarms to clear them.
