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! :-) Sent from my mobile device. Please excuse brevity and ttpos.
