Storage Analysis

Storage Analysis

Storage Analysis lists all persistent volumes in a cluster with their capacity, cost, storage class, and namespace binding. Use it to find over-provisioned or unbound volumes that are adding to your bill.

Access: Select cluster > Dashboard > Volumes tab, or Namespaces > Persistent Volumes

---

Three cards at the top of the page:

• Total Storage (or Filtered Storage) - Aggregate capacity across all volumes
• Total Cost (or Filtered Cost) - Monthly cost based on hourly rates
• Total Volumes (or Filtered Count) - Number of persistent volumes

When filters are active, the cards update to show filtered totals.

Columns:

• Volume - PV name with availability zone shown below
• Storage Class - gp2, gp3, io1, etc.
• Namespace - Bound namespace (or "Not bound")
• PVC - PersistentVolumeClaim name
• Capacity - Allocated size in GB
• Cost - Hourly cost with monthly projection

Click column headers to sort by name, capacity, or cost.

Six filter options:

• Search - Filter by volume name
• Storage Class - Multi-select dropdown
• Namespace - Scope to a specific namespace
• Team - Filter by team label (if labels are present)
• Department - Filter by department label
• Owner - Filter by owner label

A "Clear filters" button shows the active filter count and resets all filters.

Common AWS EBS storage classes and approximate pricing:

• gp3 (General Purpose SSD) - ~$0.08/GB/month. Recommended default for most workloads.
• gp2 (Legacy General Purpose SSD) - ~$0.10/GB/month. 25% more expensive than gp3.
• io1 (High IOPS SSD) - ~$0.125/GB/month + IOPS charges. Use for high-performance databases.
• sc1 (Cold HDD) - ~$0.025/GB/month. Use for infrequent access and backups.
