Usage Guidelines

Increasing the consecutive I/Os of a path can improve the efficiency of processing sequential I/Os. However, it does not apply to discrete I/Os, and an extra-large amount of consecutive I/Os causes path blockage for short periods of time. Therefore, set an appropriate value based on the your service I/O model to improve performance.


Set the number of consecutive I/Os on a path in load balancing mode to 1.

~ # esxcli upadm set lbiothreshold -n 1
