HA Deepdive

Even with all that content, there are still some common questions and misconceptions regarding this feature. The A record for vCenter Server is controlled by whatever DNS service is being used in your environment and event if you can automate the updating of that A record to the new IP address there is still the real possibility that there will be transient issues due to the DNS TTL, propagation, and caching.

DRS does not take limits or reservations into account.

The Resource Management Guide also contains a wealth of info on resource pools and this should be your starting place! If so, can I reserve a copy? Excellant news on the book.

DRS Deepdive

It seems to be a separate identity…. Basic vs Advanced One of the most common questions we tefhnical and misconceptions I hear about is that in order to get all the features of VCHA you need to deploy using the Advanced workflow. Well, this is indeed possible but with some caveats. And a very special thanks to Depdive Herold for writing the foreword!

Howeverall of the workloads and hosts will remain in the failed site without some other DR orchestration.


HA admission control policies, DRS resource pools and host affinity rules. In fact, VCHA is exactly deepdjve same regardless of how it is deployed.

DRS uses the following procedure: You need to fix your Amazon link. Also remember that in order to split the nodes across sites, you need to use the Advanced workflow. With the Advanced setup you have to do all of that work manually.

Of course the obvious question was when the DRS Deepdive would be posted. The books are printed in the US and we received the books each time within a week. If h is lightly loaded compared to Source Host: CPU reserved during migration on t he target host Cost: The in-depth discussions we had are without a doubt the most difficult I have ever experienced and were very interesting, both most of all fun!

At least not 30 days. Frank works primarily with large Enterprise customers and Service Providers. The key is that technjcal customers should be able to use Basic and not have to deal with the manual work of the Advanced workflow. In addition, lets say you need to do something that requires you to destroy the VCHA cluster such as changing certificates, changing the IP of vCenter Server, or restoring vCenter Server.

If you do have stretched L2 networks between the sites then this is much less of a discussion because you can avoid the need to change technicap IP of vCenter Server as well anv the DNS record during a failover. The result of all hosts will then be used to compute an average and the standard deviation.

More resources for migrated VM as it moves to a less utilized host Benefit: I will not be focusing on Resource Pools at all as I feel that there are already more than enough articles which explain these.

Any particular considerations when the underlying storage is vSAN? The one exception is if you happen to have a third site which has stretched L2 from the other two sites.
