How to convert Disk throughput and Block size into IOPS
How to convert IOPS and Blcok size to throughput
Formula
To calculate IOPS
IOPS = (MBps throughput / Block Size) * 1024
Explanation:
Throughput is how much a disk can write per seconds
Block size is how much one IO can write per seconds
1024 is given from the formula to conversion like KBps or MBps
Example:
- What number of IOPS should be used with Storage I/O Control to limit disk throughput to roughly 10MBps if the guest application writes 64KB blocks?
- IOPS= (10 / 64) *1024
= 160 IOPS
To calculate Throughput
Throughput = (IOPS * Block Size) / 1024
Example:
- What number of IOPS should be used with Storage I/O Control to limit disk throughput to roughly 10MBps if the guest application writes 64KB blocks?
- Throughput = (160 * 64) /1024
= 10
