Is turning on de-dupulication on a Isilon with mostly SATA disks recommended?
We are in the middle of project to migrate data to Isilon.
But have determined that the storage on Isilon is not enough to move all data to it.
So we are thinking of turning on de-duplication on the Isilon.
Our Isilon has SSDs for cache and Sata HDDs for data.
I am concerned if turning on the deduplication will impact performance heavilly.
Has anybody turned on de-duplication with SATA HDDs in the Isilon?
And did it introduce latency and have a heavy performance impact?

Deduplication on Isilon is a long running background job with very low impact to system resources or system performance. The job runs in very short cycles from sampling for duplication candidates, to creating the shadow stores. Think of it as being lots of very small jobs (start to finish) bundled into a very long running job. It is intended to just run during free cycles. I know some other storage put priority on deduplication having it inline during the write process and it can impact the performance. For Isilon, it is a post process to just help optimize the storage utilization.
