Resillency- Disperse Factor

Hi @Ajal 

For HyperScaleX, we have metadata nodes which are generally the first three nodes for deployment. Irrespective of how big the cluster is, only one node failure can be tolerated.

You can run the command /usr/local/hedvig/scripts/showmembers.exp to find the metadata nodes. It will show port 7010 for the nodes. Nodes that show only 7000 are not running metdata service.

hedvigduro> showmembers
xxx.prod:7000
xxx.prod:7010
yyy.prod:7010
yyy.prod:7000
zzz.prod:7010
zzz.prod:7000

The EC code will be 4+2, even if you have more than 6 nodes.

@R Anwar  then what is the point of giving option to select standard medium or high,

which one to select ? 

Hi @Ajal 

I reconfirmed and 3 nodes with have EC 4+2 and 6 nodes and above will have resiliency of 8+4 giving higher tolerance level.

@R Anwar thanks for the update

could you tell me what is meant by disperse factor here also if i choose high the usable capacity will be less?

Hello @Ajal
