Hi, My mission is to make a ceph cluster production ready. We already have a mock-up of 6 nodes deployed via cephadm to test ceph's features We want to install a ceph cluster to get off our dependencies to SAN and to store around 400 TB of data. We'll use mostly block storage for VMs/k8 and a bit of CephFS and Object storage Are those specs good for our purpose ? - 3 MGR/MON/RGW 128 GB RAM 32 cores (is it recommended to put RGW daemon in the same node as MGR/MON ?) - 2 MDS 16 GB RAM 8 cores - * OSD 8 GB RAM 8 cores (with high IOPS per core) We are pretty new to ceph so any advice would be appreciate ! Thanks ! Vivien
