ACS HA with vSphere
Does anybody have a deeper document into how ACS handles both vm and host level HA with vSphere. I'm looking at the 4.1.1 Admin manual Section 17.3 and 17.4 but I'm looking for more meat into how all of it actually works. Does anybody have a link or insight into this functionality?
Thanks!

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.

I filed doc bugs for two vSphere-related HA gotchas.
Document vSphere HA host tag limitation
https://issues.apache.org/jira/browse/CLOUDSTACK-4439
CloudStack should handle native VMware HA for virtual routers
https://issues.apache.org/jira/browse/CLOUDSTACK-4440
I also filed one for the traffic label config mentioned by Ilya.
Improve documentation for traffic labels configuration KVM, vSphere, and
XenServer

RE: ACS HA with vSphere
Posted by "Musayev, Ilya" <im...@webmd.net>.
Aaron,
You gap doc will be mostly between ACS4.1(stable) and 4.2 (RC). With 4.2, we cover majority of needed features, except for "CLOUDSTACK-778, better vmsync" and usage of native vmware API calls to do maintenance mode and other tasks. I assume the next release post 4.3 will make it 98% vSphere compatible.
Something undocumented I found, which needs to be documented and only applies to vSphere, if you management network is tagged, officially cloudstack does not support management tagged networks (due to some limitation with Xen). However with vSphere, tag can be defined in Traffic Label, for example "vSwitch0,1099". This is really helpful and unfortunately not documented anywhere for complex network layouts with vsphere. Also, vDs support only applies to public and guest networks.
Don't know how helpful this is,
Regards
Ilya

Thank you both the responses and that is great. I know VMware HA very
well already and was just wondering if there was anything above and beyond
in CloudStack. What I'M thinking of doing is putting together some "gap"
documentation that would enable an existing VMware admin come up to speed
more quickly on ACS. If I get brave and I like it I'Ll look into seeing
if I can get it into the official ACS documentation if everyone finds it
appropriate. Thank you!

+1 for the "set it up in a lab and try it out" first. It was during
an actual lab test that I found KVM HA fail with Apache CloudStack 4.1
despite what the documentation claimed.
FWIW, you never know what surprises are in store till you actually test
features that is critical to internal success criteria(s). CloudStack
codebase has had a lot of churn since it went open source and it is in
the user's best interest to validate CloudStack features/bugs with the
supporting documentation.

Re: ACS HA with vSphere

Hi, Aaron. For vSphere, CloudStack relies on native vSphere HA. You
must enable and configure HA in vSphere to use HA regardless of the
configuration in CloudStack. To understand the functionality of vSphere
HA I suggest checking the vSphere docs.
I'm not aware of documentation about using vSphere HA with CloudStack
besides what is in the install and admin guides. There may be things
not mentioned in the official docs, such as global settings and
bugs/gotchas. Besides checking the vSphere docs, it would be useful to
set it up in a lab and try it out. If you have specific questions you
can ask on the list and file doc bugs.
Best regards,
Kirk
