Subject Re: ACS HA with vSphere
Date Thu, 22 Aug 2013 06:34:03 GMT
Very helpful, thank you!  As I see it about the only major feature in
vSphere not supported by ACS today is Storage DRS. I think there might be
some other minor features but probably not worth the trouble right now. It
will be interesting to see what VMware may or may not announce next week
and any associated new vSphere features.
