NetApp V-series and TRIM/unmap commands


Hi, everyone,

We have a NetApp V3250 backed by an EMC VMAX 10K, which I'm led to believe supports client-side TRIM/unmap commands. The question I have is, does the V-series, or Data OnTAP generally, issue those commands? For that matter, when deleting data, does Data OnTAP ever actually zero out the blocks, or are the blocks pretty much permanently dirty once written?
