Hi,  
As I know, we can boost cpu share by changing some settings as below.

And ece use blk\_io.weight to limit disk resource for container.

> 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!

I wonder if there is a similar setting for disk like cpu share setting to allow a deployment use more disk resource.

thanks!

You can always use as much disk resource as available, the `blk-weight` only kicks in if the disk is over-provisioned to manage sharing between different instances on the same allocator

It uses the same weighting as the CPU (ie changing one cluster's CPU weight will also increase its IO weight as discussed [here](https://discuss.elastic.co/t/ece-ram-to-storage-ratio/101878/10))
