DM-Cache for spinning OSDs

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

 



Hey guys,

i have three servers with 12x 12 TB Sata HDDs and 1x 3,4 TB NVME. I am thinking of putting DB/WAL on the NVMe as well as an 5GB DM-Cache for each spinning disk. Is anyone running something like this in a production environment?


best regards
Felix
