Question about cluster expansion

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

We have a 5-node cluster that each have the following drives:

  * 4 x 16TB HDD
  * 4 x 2TB NVME
  * 1 x 1TB NVME (for the WAL/DB for the HDDs)

The nodes don't have any more room to add more NVMEs, but they do have room to add four more HDDs.  I know adding more HDDs are able to make the cluster faster due to the additional IOPs.

So my question is this:

Is it better to:

  * Add the additional drives/IOPs by adding an additional node
  * Add the additional drives by adding the the HDDs to the existing nodes

Or does it not really matter?  I would prefer to add the drives to the existing nodes (ultimately maxing them out), but just wondering if that affects performance as much as expanding by adding additional nodes.

Thanks! :-)
