CLOUDREADCACHEMAXUSAGE

Parameters

percentage

Specifies the maximum percentage of file system space that can be used for read cache data, in the cloud-container storage pool cloud cache. The default value is 95. The minimum value is 0. The maximum value is 100.

If the designated or default percentage is reached, read cache data is no longer be added to that directory path. Increase the default or your specified percentage to allow more read cache date in the directory path. To decrease the percentage of read cache data in the directory space, lower the percentage.

If the ON parameter is set in the DEFINE STGPOOL command, the read cache data is not automatically removed during ingest, and the ingest operation might experience some issues with space usage. Consider using a lower value, for example, 50%, to reserve dedicated space for ingest operations.

If the ONPREFERINGEST parameter is set in the DEFINE STGPOOL command without enough space, the read cache data is removed during the ingest operation.

Tip: If there are 50 GB or less of free space on the file system, read cache data is not added to a file system.
