LUN Dedupe and space usage

July 20, 2020, 11:12 am

Working with a small FAS2750, 2 x ~10tb Aggregates.   The only intention for this system is to use for VMware datastores via iscsi.

 

It seems thin volumes, and unreserved space luns are the general recommendation for this setup.  What isn't clear to me is how to take advantage of the space savings from dedupe.  As far as I can tell the only way to access this saved space would be to over provision luns from a volume which just feels kind of strange.  I'd basically be taking a guess at what savings I might get and would need to watch space fairly closely.

 

Looking for suggestions or just confirmation that basically over provisioning luns is the only way to use the space savings in this scenario.

Change/Edit Timezone for ONTAP

Running v9.6P3.  I'm trying to correctly set the timezone for our NetApp.  I goto Settings\Data and Time and I've tried adding a known internal time server and have also tried a valid external.  After saving and then waiting for 30+ minutes, the time doesn't change and still shows "Etc/UTC" and records time 5 hours ahead of my actual timezone (CST).  This is extremely annoying in logs and viewing snapshots.  How can I correctly set this for my timezone?  Thanks!

Hi guys. Running C-Mode 9.3 clusters. I see system manager is baked into the cluster. Does this mean that any updates to system manager ship with the underlying OnTap version and hence to update system manager one updates the OnTap version?
