Redis cache fragmentation issue

Question

Hi, We are using Azure Redis cache (basic tier). We're getting notification "Availability may be impacted from high memory fragmentation. Increase fragmentation memory reservation to avoid potential impact." but upon checking the "maxmemory-reserved" and "maxfragmentationmemory-reserved" options in the advance setting are greyed out — is this possibly something that would become available when/if we upgraded to 6?

If Yes. Would it cause any data loss on the cache itself when upgraded from 4 to 6?

Thank you in advance.

Hi @Fernando Mendoza Jr ,

Welcome to Microsoft Q&A platform and thanks for using Azure Services.

As I understand your ask, your Azure Redis Cache of Basic Tier is showing disabled options for "maxmemory-reserved" and "maxfragmentationmemory-reserved" options.

As per official documentation cache-configure,
The maxmemory-reserved and maxfragmentationmemory-reserved settings are available only for Standard and Premium caches.

Hence in Basic Tier, options are greyed out.
Standard and Premium caches would only help in this case, version upgrade from 4 to 6 would not help in enabling memory options.

Hope this will help. Please let us know if any further queries.
