How long must data be 'write-cold' before Erasure Coding can begin optimization?

Erasure Coding (EC) Analysis:

Erasure Coding is a Nutanix feature that provides efficient storage utilization by distributing data across multiple nodes.

Write-cold Data Requirement:

Write-cold duration: Data must be 'write-cold' for a specific period before Erasure Coding can begin optimization.

Duration: The required duration for data to be considered 'write-cold' is 7 days.

Explanation:

Erasure Coding optimizes storage usage by encoding data across nodes. However, this process is applied to data that is infrequently accessed or modified.

The 7-day period ensures that the data is stable and not subject to frequent changes, making it suitable for EC optimization.

Outcome:

After 7 days of being 'write-cold', the data will be eligible for Erasure Coding, thereby optimizing storage efficiency while maintaining data resiliency.
