I'm frustrated they seemed to have released it before its done - see my post from 2 weeks ago
"VSC 4 missing VAAI and getting no VMs for aligned/not aligned"
https://communities.netapp.com/message/78768
Are people successfully using it to align VMs ?
We aligned all our VMs over a year ago when Netapp cited it as a prereq for helping us solve a latency issue.
I forget how I found out about VSC 4.0 - but I usually get this info from RSS feeds of blogs.
If the online alignment is production ready I can't believe they didn't tell folks earlier this was in the pipeline since it would save folks TONS of downtime we went through last year. I remember asking back in June 2009 about "Adding VM re-alignment to SVMotion - which API?"
at that time the APIs were not there…

This maybe off topic, but I am a bit frustrated here.
Is there anyway ANYONE knows of a way one becomes abreast of new updates to Netapp software one has purchased? We have someone doing re-alignments during the late evening taking downtime to re-align these windows 2003 vms.
Any help is appreciated.
BTW, thanks Peta for posting this. This is my current method of knowing what's out there and what others are doing.

I suggest do it by batches and run in on quiet times. Also make sure you have ample space for VM snapshots.

Hi all,
I've been testing the new functionality in VSC 4 around online re-alignment. I've done some tests with a test datastore and test VM under load, all fine.
However I have an estate of over 200 datastores. Has anyone run the scan manager across all their datastores at once? Was there any noticeable impact to the VMs? As far as I can tell, I can only schedule the scan to scan everything at once. I know I could manually do batches but I need to run the scans overnight.
I've found documentation around the actual online alignment function and warnings to not do too many at once, but nothing about the scan. There also seems to be no way of stopping the scan once it starts, which makes my rollback plan in my CR for this scan a bit empty looking and hard to justify.
And a long shot, just out of curiosity, if anyone has any information on what the scan actually does would be interesting too. I can see it takes a VM snapshot for each VM in the datastore, then deletes it, but that's it. I've searched NOW high and low, but documentation on VSC 4 is pretty thin on the ground.
