Troubleshooting vCenter Server and Lesson Learned

Thu, 08 Oct 2009 05:26:00 +0000

Not often I face issues with VMware products that were previously working with flaws and I do consider VMware hypervisor and it’s components a very reliable and robust solution.

When I got into the office this morning vCenter Server service was not running and a manual restart or server reboot did not fix the issue. The event viewer showed the following errors:

Connections and Ports in ESX and ESXi

Tue, 06 Oct 2009 04:25:00 +0000

I have previously in the post “PCI DSS, Network Ports and your VMware Environment” discussed the network port requirements for deploying PCI frameworks, tightening your environment or just relaxing firewall rules.

Today I came across a diagram and a great tool to help administrators to identify these connections and the interrelation between different VMware products. The documents are maintained by Dudley Smith and I also recommend a visit to his blog.

(Take Care) vSphere Virtual Machine Upgrade Process

Wed, 16 Sep 2009 04:18:07 +0000

I decided to name this post as "Take Care" as I found myself looking for promissed VSphere features that will not be avaiable in most Corporate environments therefore you should prepare yourself, and your environment.

PCI DSS, Network Ports and your VMware Environment

Tue, 11 Aug 2009 01:08:31 +0000

Recently I have been involved with deployment of PCI DSS at TeleTech for the APAC region. It's good to say that TeleTech has been oficially declared PCI compliant however VMware is still on track to get their products certified. This puts a barrier for organizations with high virtualisation levels but I am not here to discuss the PCI requirements and its validity.
