VSC 4 and online alignment - anyone used it in anger?
|
|
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.
Thanks,
Peta
