Hello Adam, Can you describe what performance values you want to gain out of your cluster? What's the use case? EC oder Replica? In general, more disks are preferred over bigger ones. As Micron has not provided us with demo hardware, we can't say how fast these disks are in reality. Before I think about 40 vs 25/50/100 GbE, I would reduce latency of these disks. -- Martin Verges Managing director Hint: Secure one of the last slots in the upcoming 4-day Ceph Intensive Training at https://croit.io/training/4-days-ceph-in-depth-training.
