Performance impact on Data Domains regarding space?
Hi everyone
I've heard some negative feedback from a colleague regarding an non EMC data dedup solutions. As soon as there is less then 30% of less space on the system (70% used) the system is getting really slow. Is there a similar issue with DD as well? Are there any facts to consider regarding availability and performance?
I've been dancing around 90% few times and I could not see much of impact at that time (DD890). I think best practice is to stay below 80%, but up to 90% of usage just before cleanup does its job should be line you should not cross to be safe.

i personally try to stay below 90%, anytime we go above 90% we begin to fill it with our RMAN completion times.
