Cache tier or RocksDB

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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?
