Standard Disk Below Target Threshold

This recommendation looks at usage of Standard Persistent Disk storage. Standard Persistent Disks are a type of disk storage in GCP that is suitable for large data processing workloads that primarily use sequential I/Os and is backed by standard hard disk drives (HDD), providing efficient and reliable block storage for a variety of use cases. Changing your storage option to Standard Persistent Disk can result in cost savings.

Note: If you create a disk in the Google Cloud console, the default disk type is Balanced Persistent Disk. If you create a disk using the gcloud CLI or the Compute Engine API, the default disk type is Standard Persistent Disk.

CloudZero has a target threshold for Standard Persistent Disk of 50%.

Recommendation

Optimize costs by evaluating the workload for the highest-cost disks identified and consider whether using a cheaper storage option is appropriate.

To change the type of an existing Persistent Disk volume, you must migrate your data from the current disk to a new type of disk. A disk's type cannot be directly changed.

Migrating your data to a new type of disk

• You must create a snapshot of the existing disk and use that snapshot to create a disk of the new type
• After you create and validate the new disk, you can delete the snapshot and delete the original disk
