Hey!
I have a setup with blueStore with 8 hdd and 1 nmve of 400GB por host,
how would I get more performance, by using the nmve as equal RocksDB
partitions (50GB each), setting it all as a cache tier osd for the rest
of hdd or doing a mix with less DB space like 15-25GB partitions and the
rest for cache tier osd?
Has anyone tested it?
