- According to the IM documentation the requeriment for disk input/output is 200 Megabytes/second.
- Vertica recommends a disk block size of 4096 bytes (4K)
- In order to calculate the IOPS based on MB/sec or vice versa the following formulas could be used:
IOPS = (MBps Throughput/KB per IO) * 1024
MBps = (IOPS * KB per IO) / 1024
Running the calculations:
IOPS = (200 / 4) * 1024 = 51200
