disk scrub generating too much i/o

Hi,

 

our FAS3160 filer reports a crazy i/o load during disk scrub interval.

 

On an aggregate with 7 SATA disks, DFM reports a throughput of 4000 blocks/sec, which I think is impossible.

 

We also have our monitoring system, which uses NetApp API, reporting the same result.

 

How can this be possible?

 

Any help appreciated
