Overview
VAST compute clusters are container orchestration clusters that you can deploy on the VAST cluster's own hardware infrastructure and use to handle container orchestration for VAST DataEngine.
VAST DataEngine requires at least one compute cluster, which can be either a VAST compute cluster or an external Kubernetes cluster.
As a tenant admin user logged into a tenant VMS, you can see details of VAST compute clusters that are linked to DataEngine on the tenant.
When enabling DataEngine on a tenant, an attached compute cluster is automatically linked. The wizard for enabling DataEngine shows you that the compute cluster is linked and allows you to continue with the DataEngine configuration without linking another compute cluster.
Viewing DataEngine Linked VAST Compute Clusters
From the DataEngine menu, select Compute Clusters.
DataEngine Linked Clusters are listed. These are all compute clusters that are linked to DataEngine on the selected tenant.
The following properties are displayed:
Cluster name
The name of the compute cluster.
Type
The type of compute cluster:
VAST. A VAST compute cluster.
External. An external compute cluster.
API Server URL
The IP of the server internal to the compute cluster to which you can send API requests, such as to scrape metrics.
Tags
Tenant specific tags associated with the linked compute cluster. These are distinct from the tags defined in the compute cluster's global configuration for the VAST cluster. They are added by editing the DataEngine linked cluster, which you can do by right-clicking the cluster in this list.
Description
A description of the compute cluster, if defined.
Modifying Tenant-Specific Description and Tags for DataEngine Linked Compute Clusters
From the Data Engine menu, select Compute Clusters.
From the Tenant dropdown, select the tenant.
Under DataEngine Linked Tenants, right-click the compute cluster and select Edit.
Enter a tenant-specific description in the Description field (optional).
Under Tags, click Add tags and add any tags that you want to add for the tenant (optional).
Click .
The tags you added appear under the Tags column of the DataEngine Linked Tenants list for the compute cluster.
Monitoring and Analytics
Compute Cluster Analytics in the VAST Web UI
The Compute Cluster Analytics page provides performance metrics broken down by tenants, namespaces, pods, deployments, CNodes, and services.
The Compute Cluster Analytics page is available only if a VAST compute cluster is linked to DataEngine on the tenant.
To view compute cluster analytics:
From the left navigation menu, select Analytics and then Compute Clusters.
