I am new to Ceph cluster.
I have 3 nodes. two nodes has 1TB NVME and 1TB SSD. third node has 2TB NVME. Recommendation is to have one SSD per OSD and 12 even size OSD in a three node cluster. Should i partition 2 nodes with 500GB (8 OSD) and third one (2TB) with 4 partition (4 OSD). Is it a reasonable approach? What's the benefit of 12 OSD in a three node cluster?
The host in all nodes is running on a separate SSD.
