Hi Thomas, I am by no means expert, but here couple of thoughts. The cache filling up could be raid controller cache filling up and not emptying fast enough. To have valid results, you could use another tool than dd, or run dd multiple times after another. I don’t think, network have anything

Hi Thomas, so you are seeing high load on your storage and you are asking 'why'? an answer with the facts you give would be: you are using your storage, so, you have storage IO. so, if you want to dive deeper: -which storage are you using, specs would be nice. -which host model are you using?
