Once again just like the past year, the VMware Education team has managed to organize a one day bootcamp for those who are planning or wanted to find out more on becoming a VCAP and VCDX.  This is a similar bootcamp that has been held several times in US and its really rare opportunity that this is conducted in ASEAN.

While this is a great move, this will be more applicable for those who are already a VCP.  As the number of vacancy is limited, I would encourage anyone who are a VCP and keen to pursue a VCAP or those who have VCAP and intend to give VCDX a shot to register now!

Here is the registration link.  Please be responsible and only register if you are able to attend as this is a rare opportunity and we will be having our VCDX#001, John Arrasjid to host this bootcamp.

Below is the respective countries in ASEAN where the bootcamp will be held:

11th Mar 2014  Malaysia (in collaboration with MDeC)

13rd Mar 2014  Singapore

17th Mar 2014 Vietnam

VMware High Availability Failover Simulation

Having working as a presales consultant, I have realize as virtualization gets more complex, more and more people are confused with the basic fundamental and have forgotten and felt uncertain.  Certain test are also perform wrongly or understand incorrectly.
Here is a short video to demonstrate this on how VMware High Availability (HA) test is conducted and configured as stated in this KB.  Do note that only vSphere 5.x methods are shown in this video.

Many I have spoken with is still unclear how HA really works.  You can refer to Duncan Epping's post here on more deep dive of HA.

HA is enabled from vCenter with just a simple checked box.  Once that is enabled, the ESX servers will have a HA agent (FDM) running and this will communicate within the ESX servers in the cluster and with one of them as the Master role communicating with vCenter.  In vSphere 5.0, in the new HA architecture, there will be one Master node and rest as salves nodes.

In vSphere 5.0, datastore heartbeat was…

vExpert 2014 Application Opens!

This year the VMware vExpert applications is has started early!  You can find the details here.  You can read my previous post about my first experience during my first application back in vExpert 2012.

This year for existing vExpert 2013, you can apply using a short application form using a Fast Track application.  This is very useful and save a lot of trouble of filling all the information all over again.  Great job to the program team!

The second new thing is a quarterly nomination which can be done.  So if you are not doing it now and couldn't get this accreditation, don't worry you can still do your part and be nominate in the next.
This will allow more individuals and professionals to be awarded.

Read about the requirements, you never know you can just be awarded this accreditation.  Apply for it if you are not sure whether your contribution is been described.

Don't wait further before it ends on 6th March 2014.

vSphere 5.5 App HA Setup Overview

I decided to document about the setup of vSphere App HA.  This was mainly due to many roadblocks encountered during the installation.  I was not able to find a proper guide or anyone doing a detail explanation of the setup process.  Also the poorly written documents and documents are all over the place as well.

Instructions from the document is also difficult to understand.  I did this many times in my lab to come out with a smooth out process via video and list down all the hiccups you will face.

The App HA documentation site can be found here.

vFabric Hyperic Server documentation can be found here. (This is pointed to version 5.7.x as the vFabric Hyperic Server binary at vCenter 5.5 for App HA is also at 5.7.x.)
