Virtualisation virgin pitfalls for the bottom line E-mail
by Mike Bantick   
Sunday, 27 July 2008
The criteria were laid out, with parameters of the project broadly being;

* Separation of client environments
* 24/7 availability.
* Disaster Recovery within 4 hours
* Mixed OS environment needs
* Costs of course needed to be minimised

Deciding to separate client from client (in this case Company X had seven clients – major financial institutions), development, testing, production as well as housing the JAVA applications all in their own environments.  All this separation meant the obvious answer was to virtualise the mid-range hardware.

The other consideration leading to a VM type solution was the cost of housing extra servers in the Data Centres and that volume licensing of OS software meant that the cost of creating new virtual machines was not great.

Being relatively green in the mid-range world, Company X decided to employee consultation to work with the X system administrators to thrash out a VMWare ESX solution.

The art of consultation is worthy fodder for a further iTWire article, but for now let us just say that a good consultant is flexible enough to enter a client site with an open mind and the ability to adapt or offer improvements to a companies processes.

For Company X, their first exposure to VMWare consultation was not good.  The consultant in question, though obviously experienced in producing solutions for a “typical” ESX implementation, did not take the time to understand Company X’s specific structure and needs. 

Much of the blame does not fall squarely upon the individual consultant, but stems as a result from the initial quotation process.
