Hi, I'm thinking of using SSD for cache on CEPH where the SSDs are on the same OSD nodes with HDDs. My options are using CEPH Cache Tiering or using another cache software like bCache or FlashCache. On the second option, the SSDs will only cache data related to HDDs on the same node only. Any experience of both options? Actually, I don't have idea how CEPH Cache Tiering is working. What data is cached? Is there any inter-nodes cache transfer? Best regards, -------------- next part -------------- An HTML attachment was scrubbed...
