VMWare Migration Gone Wrong

We are in the midst of transitioning a client from using physical servers to a VMWare vSphere platform. Our team set up proof-of-concept (POC) and ran countless demonstrations to ensure that all systems, including mission critical applications ran smoothly together.

We were able to complete about 90% of the migration process before reaching a serious problem! The VM cluster began to malfunction. One by one, physical nodes lost connection to public networks. There were no definite patterns that could unveil a concrete reason for the glitches.

Considering that the old switches operate on ISO the 100Mbp may have been the cause of the problem.  We added new ones in front of the core switch; but still no success. Bouncing the network on a physical server caused it to re-establish a connection. Everything pointed to the network simply being unplugged, but that was not the case.

After performing NIC teaming and attempting to transfer cables into different switches, the host would lose all network visibility.  Many possibilities were exhausted but our team is coming closer to a solution.

Complex problems like this one cannot be resolved with simple research. If these issues did not arise we wouldn’t be in business.  That’s why we are continuing to address this problem head on, boosting our resources and making sure we are doing everything we can to provide 24-hour support for our client.

 I will continue to share updates on our progress.
