VMware Configuration Maximum

One of the many documents that we always refer to for vSphere is the configuration maximum. Back in the days, I still remember VCP was tested on it.

Though this document is good to refer to, there are other components such as NSX, vRealize Operations, etc. that have a certain maximum that we would search high and low for it.

VMware has released a site that contains all these maximums information. Though this is not complete, this will be the single source of truth when you find that documentation might not be updated.

Not only do you get to see the maximum, but you can also even compare previous versions limits.

It is very easy to use, Just 1) Choose a product, 2) Select the version, 3) What type of maximum, you can choose more than one, 4) To display the limits.

Now head over to try it out.

VMUG Singapore Cloud Automation Services

You see it right. You hear it right. Its Cloud Automation Services that you will be seeing during this coming VMUG Singapore event on 17th Jul, Wed.

VMware vExpert 2019 Two Subprograms Are Now Open!

A few days ago, the vExpert 2019 second half application. Now the vExpert Cloud Management and vExpert NSX subprograms are open.

Please note this is based on your past year contribution on the two specific categories namely NSX and Cloud Management. This year Cloud Management is new into the subprogram.

So head over here, and apply for the subprograms if you specialize in this area.

VMware vExpert 2019 Second Half Application Now Opens!

The application for VMware vExpert 2019 has now opened again! As usual, there will be two application period one at the beginning of the year and one in the mid of the year.

For those who have missed the first time round, this is your last chance. For those who have not accepted into the program in the first application, this is your time to prove your worth into spending thoughts of your contributions to the application.

The announcement can be found here. The application can be found here. Before you can apply, you would need to create an account. The closing date is 12th Jul 2019.

As usual, you can read about the three tracks, Evangelist, Partner and VMware Partner Network.

As a vExpert Pro together with others, we assessed the applications together with the vExpert Program team. Please put some effort into the applications.

Some common mistakes we see. We have seen simple one-liner application which there is no justification to grant anyone the credential of vExpert. Also, past years effort is good, but vExpert is a yearly renewal credential which requires a yearly contribution. So if you have stopped doing it, and was a vExpert in the past, it is unlikely you will be granted vExpert 2019 if no effort was done in the past one year. Lastly, do not just state you have spoken in an event without any evidence. Show us some links to it, or even point it to your LinkedIn past post or something.

If you need help or advice or need a mentor on how to achieve vExpert, feel free to approach any of the 46 vExpert Pro from the above link for guidance. I am sure every one of them is more than willing to help.

I am offering myself to guide or advise anyone who needs any help in the South East Asia region since I am based in Singapore and timing works just right. Ping me if you need help.

You can find me on Twitter or LinkedIn and we can schedule a call to get it through.

Good luck!

VMware vCenter High Availability (VCHA)

With the release of vCenter 6.5, a built-in native High Availability (HA) feature was introduced. This has been a long-awaited feature since the end of availability of vCenter Server Heartbeat since vCenter 5.x.

With the release of VCHA, I came across many times people asking how can we implement it?

There are a few articles from VMware that show some of the supported topologies. However, with the realize of vSphere 6.7 U2, the recommended vCenter Server deployment is with embedded PSC. In this case, we will just look at the topology that has an embedded PSC. This is welcoming since we have less component to handle and need not require a load balancer just to load balance PSC.

Let us go through some of the common questions been asked.

How many instances does VCHA deploy?
With VCHA, you would have three instances of vCenter namely: vCenter Server  (Active), vCenter Server (Passive), vCenter Server (Witness).

How many vCenter Server licenses do I need and which edition?
The licensing requirement for this case only needs one vCenter Server Standard license to utilize this feature without having to license all three instances.

In VCHA, the vCenter Server instance is of the same configured sizing for all three, can we resize the witness?
Yes. In the Basic configuration, this is done automatically for you. If you are doing in Advanced, you can change the vCPU and memory to 1 vCPU and 1 GB respectively.

Can I place the witness on a 3rd site?
Yes, you can but why do you need to. There is no strong value. The reason is VCHA is a local site availability to keep vCenter Server available at the local site and not a disaster recovery solution. It is not used for site failure purpose but local site component failure. Placing the witness to another site is not wrong but you added complexity when there is a breakage between the site where the witness lose connection to the main site. The bandwidth round trip time (RTT) requirement for the three instances between each other needs to be within 10ms. The recommendation is to place all three instance on different ESXi server in the same cluster or if you are worried on cluster outage, then across cluster within the same site.

Can the witness run as a physical server?
No. As VCHA instances are all preconfigured virtual appliance, it cannot be installed on a physical machine. VCHA is only available in the virtual appliance option so you cannot do your own installation.

Can the witness run on a standalone free ESXi hypervisor?
Yes, however, the free ESXi hypervisor does not have a license attached to it. Naturally, the witness will not have VMware support even though you have purchased support for the vCenter Server.

How to upgrade VCHA?
The easiest way is to destroy and upgrade the vCenter Server and deploy VCHA again. Refer to this article.
