- Be sure to use the appropriate storage type. DDVE on Google Cloud uses the standard persistent disk (HDD) for the root disk. The NVRAM disk and all metadata disks use the SSD persistent disk.
- Each instance type supports both Block Storage and Object Storage solutions, but the maximum supported capacity is 16 TB.
- The metadata disks can be deployed incrementally. The minimum incremental size is 1 tebibyte (TiB). Add metadata disks as required up to the supported system capacity. When adding the volume, there is no requirement to specify a spindle group. The spindle group assignment is balanced automatically when storage is added. It is recommended to not manually set or change the spindle group setting. Run storage show all to verify that each data volume has been assigned to a different spindle group.
Data storage configuration notes for object storage
- The bucket that is provided during file system creation must be empty, otherwise file system creation fails.
- When the file system is destroyed, the associated bucket and the objects it contains are not automatically deleted or removed. The bucket must be deleted intentionally to avoid incurred costs with the content stored in the object store.
