You allocate storage capacity for analytics data collected from the management products and from the number of tenant virtual machines that is defined in the objectives of this SDDC design.

This design uses medium-size nodes for the analytics and remote collector clusters. A vRealize Operations Manager node of a medium size requires 266 GB of free space for data. To collect the required number of metrics, you must add a 1 TB VMDK to each analytics cluster node.

The analytics cluster processes a large amount of objects and metrics. As the environment grows, the need to add more data nodes to the analytics cluster will emerge. Refer to the vRealize Operations Manager sizing guidelines in VMware Knowledge Base article 2093783 to plan the sizing requirements of your environment.

Analytics Cluster Node Storage Design Decision

Design Justification

Design Implication

SDDC-OPS-MON-007

Provide a 1 TB VMDK for each analytics cluster node.

Provides enough storage to meet the SDDC design objectives.

You must add the 1 TB disk manually while the virtual machine for the analytics node is powered off.

Deploy the remote collector nodes with thin-provisioned disks. Because remote collectors do not perform analytics operations or store data, the default VMDK size is sufficient.

Remote Collector Node Storage Design Decision

Design Decision

Design Justification

Design Implication

SDDC-OPS-MON-008

Do not provide additional storage for remote collectors.

Remote collectors do not perform analytics operations or store data on disk.

None.
