What Is the Minimum Size Block Storage Volume I Can Deploy to a VKE Cluster?

Vultr Kubernetes Engine (VKE) supports two types of Vultr Block Storage through the Container Storage Interface (CSI):

• Vultr Block Storage (NVMe): High-performance NVMe storage available in regions that support it. Volume sizes range from 10 GB up to 10 TB. When available, NVMe is used by default for improved I/O performance.
• Vultr Block Storage (HDD): Standard HDD storage available in most regions. Volumes range from 40 GB up to 40 TB.

To check which storage classes are available in a specific region, use the List Regions API endpoint. The response returns:

• block_storage_storage_opt – indicates Vultr Block Storage (HDD) availability.
• block_storage_high_perf – indicates Vultr Block Storage (NVMe) availability.

Use this information to select the optimal storage class for your workloads based on performance and regional availability.
