clusterSettingsUUID is in your node or cluster configuration file is to enable the cluster to
remember the settings UUID when all nodes are rebooted at once (for example, after certain
upgrades, after a power outage, or after a network outage.)
3.7.1. Enabling Logging
The logging host, port and level can be updated to either temporarily or permanently redirect the
cluster logs to a different location or a different log level. This can be particularly useful when
troubleshooting an issue in the cluster that requires a more granular report of cluster activity.
3.7.2. Replication
The frequency of the cluster's multicast broadcasts can be modified by changing the Replication
Multicast %. The higher this percentage, the more frequently the cluster will communicate UUIDs to
other nodes and other services like DX Content Router.
3.7.3. Suspend
This option allows an administrator to temporarily suspend volume recovery efforts in the cluster for
scenarios where data is not actually at risk but a network or power outage has taken one or more
nodes or perhaps even a whole sub-cluster off-line. Suspending volume recovery prevents cluster
activity churn and reduces the risk of capacity issues due to over-replication during an outage or
upgrade. Volume recovery will remain suspended until it is manually reset by an administrator.
This feature should never be set to suspend indefinitely as this would hamper one of DX Storage's
primary data protection layers.
3.7.4. Power
DX Storage by default supports an adaptive power conservation feature that allows a node to spin
down its disks after a configurable sleep parameter and wake up to check disk and content integrity
after a configurable wake parameter. See the section on adaptive power conservation in the DX
Object Storage Getting Started Guide for full details. Administrators can update the default sleep
and wake after times from the Settings page. Additionally, administrators may set a percentage of
the maximum potential power consumption the cluster should utilize for instances when strict power
usage is required. If the Full Performance Mode option is selected, all power saving values remain
as previously set but they are ignored and the cluster runs at full power.
3.7.5. Managing Tenants
For information about managing tenants, see Chapter 4, Managing Tenants
3.8. Cluster Name
The name of the cluster is configurable through the node and/or cluster configuration files and
cannot be modified at runtime.
3.9. Cluster Multicast Address
Nodes in the cluster use a multicast address to broadcast cluster wide messages. There is a single
multicast address for the cluster. The multicast address cannot be modified at runtime and is
configurable through the node and/or cluster configuration files.
3.10. % Used Indicator
The % Used indicator provides a helpful computation of cluster available, licensed and total physical
space for monitoring purposes. The indicators include color highlighting as described in the table
