How does ece limit disk iops for es node?


(Rockybean) #1

Hi,
As we know, docker provides capability to limit disk iops by using 'blkio-weight' parameter.

I notice ece set different 'blkio-weight' for different size es node.

What is the strategy behind this?

Thanks!

The relative weight of the different clusters is proportional to their capacity (which is how CPU shares are also calculated)

Specifically, the calculation is something like min(1000, 1024*(cluster_mem/total_allocator_memory)*120%), but that's an internal implementation detail subject to change.
