Virtualization with VMware vSphere (ESXi) Hypervisor

One of our servers, collocated in our office, crashed couple of weeks back. We took this opportunity to virtualize most of the stuff, earlier only some intances were virtualized.

Installing and setting up VMware vSphere Hypervisor is a straight forward process, even the process of creating virtual-machines.

Most of time, I spent was figuring out:

I am not going to cover details of installation and network configuration. I might write more posts in future to cover specifics. Meanwhile, I would love to answer the comments, if I know or share anything I know.

Anyway, this is what we have now:

We are very happy with the improved performance and stability, and the way hardware is properly used. Thanks to VM templates, clones and snapshots, we would be able to provision above infrastructure with minimal downtime.

I would soon replace Windows Server with Zentyal (eBox), which I believe, can handle most of things. However, we would need another Windows XP box to run some software (proprietary), which only runs on windows, to manage various other devices (EPBX, Access-Control-System, etc.).

We now have relatively more scalable infrastructure, more virtual machines can be created to take care of email-server, svn-server, etc.

We are yet to invest in a sophisticated storage device such as DAS or NAS or SAN, hence we are relying on some cheap tricks here:

Finally, I could execute some of things I planned more than two years back.
