we've got a FAS3270 with BSAS- and SAS-shelves. The BSAS-aggr contains a lot of different volumes and many (>100) virtual win7-clients.
Atime-controlledjobstarts a virusscan onallwin7-clientsat the same time (thatiswrongandmustbe changed) and the performance on the BSAS-aggregat an all it's volumes is down. But we also noticed, that the hosts witch uses the SAS-aggregat (on the same controller) become a performance impact! Why?
We are usingOnCommandInsightandseetheproblemsintheBSASaggregate. Butwedo not know,whyalso "SAS-systems"areconcerned (IstheControlleroverloaded? NVRAM, ...??).
