+To ensure the best performance conditions for your cluster workloads that operate on {oci-first} and on the {ocvs-first} service, ensure volume performance units (VPUs) for your block volume are sized for your workloads.
+
+The following list provides some guidance in selecting the VPUs needed for specific performance needs:
+
+* Test or proof of concept environment: 100 GB, and 20 to 30 VPUs.
+* Base-production environment: 500 GB, and 60 VPUs.
+* Heavy-use production environment: More than 500 GB, and 100 or more VPUs.
+
+Consider allocating additional VPUs to give enough capacity for updates and scaling activities. See link:https://docs.oracle.com/en-us/iaas/Content/Block/Concepts/blockvolumeperformance.htm[Block Volume Performance Levels] in the Oracle documentation.
