What is the relationship between logging volume size and storage used in VPLEX?

In the context of VPLEX, logging volume size directly affects the efficiency of data storage and management. The relationship of "1 byte for every 16KB" indicates how VPLEX optimizes the use of logging space.

When VPLEX processes data, it requires logging to track changes and ensure data consistency across distributed storage. By using 1 byte for every 16KB, VPLEX achieves a balance that minimizes the overhead required for tracking these changes, while still providing enough granularity to manage the data effectively. This optimization is crucial for performance, as it allows VPLEX to maintain high throughput without consuming excessive storage for logging purposes.

In this case, the other options either represent less efficient logging practices or do not match how VPLEX handles the relationship between logging volume size and storage usage. By understanding this relationship, users can better appreciate the architectural considerations inherent in VPLEX system design and data management strategies.
