11 DR Series Appliance Cleaner Best Practices
3.1.1 Cleaner considerations
1. Additional cleaner runtime is required as more data is ingested or begins to age out.
2. When the cleaner is triggered to run by manual, scheduled or forced methods, the cleaner is run at the
same priority as ingest and replication.
3.1.2 Scenario 1: Cleaner analysis and adjustments
Raymond has been successfully running his DR appliance at his computing center for the past 3 years.
Because his DR has recently been reporting poor savings and performance is slow, he feels his cleaner is
not completing within the Dell recommendation of a 7 day timeframe.
Inspect Raymond’s cleaner results are shown below:
Since Raymond’s cleaner is not completing within 7 days, (666,060 / 86,400 = 7.7 days) he will schedule
his cleaner to run for 40 hours during the week.

Raymond would like to determine if his adjusted cleaning schedule is adequate for his environment, so he
waits one week before he analyses his cleaner runtimes. Raymond then runs the stats --cleaner
command.
