Ceph recommendations for ALL SSD

["Ramakrishna Nishtala (rnishtal)" <rnishtal@xxxxxxxxx>]

Hi

Any suggestions/recommendations on all SSD  for Ceph?

 

I see SSD freezes occasionally on SATA drives, thus creating spikes in latency at times. Recovers after a brief pause of 20-30 secs. Any best practices like colocated journals or not, schedulers, hdparms etc appreciated. Working on 1.3.

 

Regards,

Rama
