Hi Cephers,
We intend to upgrade our Cluster from Jewel to Luminous (or Mimic?)
Our model is currently using OSD File Store with SSD Journal (1 SSD for 7 SATA 7.2K)
My question are:
1.Should we change to BlueStore with DB/WAL put in SSD and data in HDD? (we want to keep the model using journal SSD for caching). Is there any improvement in overall performance? We think with model SSD cache, FileStore will write faster because data written in SSD before flushing to SAS, whereas with BlueStore, data will be written directly to SAS.
2. Do you guys ever benchmark and compare 2 cluster: FileStore SSD (journal) and BlueStore SSD (DB/WAL) like that?
Thanks in advance.
