Recommended value of View Storage Accelerator

Hello,

Since Horizon 8, the maximum value of View Storage Accelerator has increased to 32GB. Could you tell me the recommended values or formulas?

The estimated size of the digest file is 0.5% of the logical disk
size in the case of an SHA1 hash and 4K block size—when collision detection is disabled. The estimate is 1.2%
of logical disk size in case of primary and secondary hash—when collision detection is enabled. https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vmware-view-storage-accelerator-host-caching-content-based-read-cache-white-paper.pdf

CBRC uses a RAM cache to manage the cached disk blocks. The per-VMDK digest file is also loaded into memory.

CBRC should not be enabled under memory-overcommit environments. If a host is memory over-committed and CBRC is enabled – the memory pressure is increased as CBRC also uses memory for the cache. In such cases, the host could experience increased swapping and the overall host performance could be impacted.

Should plan according to size of the environment and requirement.

Thank you.
I understand why the default is 1GB and the maximum has increased from 2GB to 32GB.
