An installer deploys a new environment that consists of a single hybrid array with a mix of SSDs and 10K disks. The installer initially connects several servers that run transactional data. The installer then migrates a large amount of file data to the new array. The servers perform very well for the first few hours. The performance then drops suddenly and significantly. The database administrator reports that the latency has suddenly increased beyond what was expected.
What is the cause of the sudden drop in performance?
