Make Sure the Switch is Set to Autonegotiate Speed/Duplex Settings
All Ethernet ports on the cluster nodes are set to autonegotiate speed and duplex settings with
the Ethernet switch. The switch to which the SnapScale is connected
must
be set to
autonegotiate; otherwise, network throughput or connectivity to the node may be seriously
impacted.
Cluster Restart Required when Switching the Storage Network to or from Switch Trunking
or Link Aggregation (802.3ad)
To prevent the interruption of communication on the Storage network during reconfiguration
of the Storage switch, the cluster must be shutdown before changing the Storage network
bond setting to or from Switch Trunking or Link Aggregation (802.3ad). After all the Storage
switches have been reconfigured, restart the cluster normally by turning the nodes back on.
Configure the Client Switch for Load Balancing
If you select either Switch Trunking or Link Aggregation (802.3ad) network bonding
configuration for the Client or Storage network bond, be sure the switch is configured correctly
for that bonding method
after
configuring the bond on the cluster. No switch configuration is
required for Adaptive Load Balancing (ALB).
Edit Storage Network Properties
IMPORTANT: Changing the bond type for your SnapScale's storage network may require changes
to your network switch.
The bond type for the Storage network of a SnapScale cluster can be changed as needed.
CAUTION:
All cluster nodes must be online when their bond type is changed. After changing the
bond type, the cluster must be restarted. If the switch is being reconfigured, the cluster must be
shut down completely, the Storage network switches reconfigured to the new bond type, and then all
nodes restarted.
The following bond types are supported:
•
Failover
•
Load Balance (ALB)
•
Switch Trunking
•
Link Aggregation (802.3ad)
