The estimated processing time can be calculated by using the equation:
total-volume*-capacity (GB) / health-check-performance-value (GB/s)
To calculate the health check performance value (GB/s), use the following equations and the values listed in the following table:
- If performance-per-volume x number-of-volumes* < system-performance, health-check-performance-value (GB/s) = performance-per-volume x number-of-volumes*
- If performance-per-volume x number-of-volumes* ≥ system-performance, health-check-performance-value (GB/s) = system-performance
where
*These volumes indicate DRS-VOLs and all deduplication system data volumes (data store).
The expected performance might not be achieved depending on the I/O loads on the system, the number of volumes among the controllers, or the volume capacity. Therefore, the health check processing might take about 2 through 5 times longer than the estimated processing time.
