vCenter High Availability Deep Dive – Part 1 – VMware vSphere Blog

There is one additional item that you may be wondering about, though. At least not 30 days. More resources available on source host due to migration Benefit: The key is that many customers should be able to use Basic and not have to deal with the manual drw of the Advanced workflow. Share on your social network: On top of that each section contains basic design principles that deeepdive be used for designing, implementing or improving VMware infrastructures.

If Cost Benefit and Risk Analysis accepted simulate move v to h measure new cluster-wide load imbalance metric as g Return move v that gives least cluster-wide imbalance g. So how does it detect an imbalanced Cluster?

Otherwise, even though it sounds simpler, you still have some work cut out for you. With the Advanced setup you have to do all of that work manually.

As said every 5 minutes DRS will calculate the sum of the resource entitlements of all virtual machines on a single host and divides that number by the capacity of the host: Remember that the outcome is the same.

Based on these consideration dwepdive cost-benefit-risk metric will be calculated and if this has an acceptable value the VM will be consider for migration. During QA adn ordered several proof copies. David can be found blogging at http: The estimated delivery dates provided by Amazon really look promising. This is evidenced by the fact that VCHA only protects vCenter Server and not the workloads or hosts being managed by it.


Any particular considerations when the underlying storage is vSAN? But most of all I would like to thank Duncan for giving me this opportunity to work together with him on creating this book.

The book should also be available e-reader format epub or kindle for those that have invested in e-readers or just find it more convenient to download the file. If you deepdige have stretched L2 networks between the sites then this is much less of a discussion because you can avoid the need to change the IP of vCenter Server as well as the DNS record during a failover.

As said every 5 minutes DRS will calculate the sum of the resource entitlements of all virtual machines on a single host and divides that number by the capacity of the host:. Every migration recommendation will get a priority rating. So it seems that the book will be available on amazon. 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.

It appears CreateSpace published books appear on amazon. First of all we want to avoid a constant stream of VMotions and this will be done by weighing costs vs benefits vs risks. Before discussing the contents of the book I would like take the opportunity to thank our technical reviewers for their time, their wisdom and their input: And a very special thanks to Scott Herold for writing the foreword!

DRS Deepdive

The following procedure is used to form a set of recommendations to correct the imbalanced cluster:. 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!

There is also a fair amount of work to hha VCHA setup to work across sites as well as additional operational effort to maintain it, e. Protect vCenter Server within a site as you are much more likely to suffer a failure from hardware, network, or storage than a deepdive site failure. You need to fix your Amazon link.


VCHA, if configured properly, will indeed recover your vCenter Server Appliance to an alternate node running in another location. Thanks, Eric Sloof received a proof copy of the book and shot a video about it. Ad is the owner of Yellow-Bricks. This is absolutely false.

HA Deepdive

Frank works primarily with large Enterprise customers and Service Providers. This priority rating is based on the Current host load standard deviation. This means that every time you upgrade, replace certificates, or need to re-deploy the VCHA cluster you will have to tear down and manually seepdive the VMs, move them to where they need to run, resize the Witness, and re-setup all the DRS rules.

In his role, he covers vSphere Lifecycle. What if you have multiple locations and you want to deepidve vCenter Server from a complete site failure?

When deploying VCHA try to use the Basic workflow when at all possible to make the solution easier to maintain and deploy. The one exception is if you happen to have a third site which has stretched L2 from the other two sites. I think, in hindsight, it may have tschnical better to call these Automated Basic and Manual Advanced. This is the description of the book that is up on CreateSpace:. Excellant news on the book.

Skip to primary navigation Skip to content Skip to primary sidebar After spending almost a year on writing, drawing and editing, the moment Duncan and I waited for finally arrived… Our new book, the vSphere 4. Of course the obvious question was when the DRS Deepdive would be posted.

Also remember that depdive order to split the nodes across sites, you need to use the Advanced workflow. Frank is the owner of frankdenneman.
