Characterization and Prediction of Performance Loss and MTTR During Fault Recovery on Scale-Out Storage Using DOE & RSM: A Case Study with Ceph

Recognizing the impact from cluster recovery operations on performance and mean time to recovery (MTTR) is essential to maintain service and availability objectives. Testing the impact of recovery operation can reveal a cause-and-effect relationship between recovery parameters and responses of performance and MTTR during the recovery process. This study introduces a combination of systematic metho...
