Too Big To Fail – VM Density and HA

Over the last few years, we have heard the term “too big to fail” thrown around in many conversations. Often, this has been used to describe large organizations whose influence within a particular market has elevated them to a point where their failure would have a devastating impact on theirs or related markets. In the United States, this term has been used to justify government intervention where the cost of failure would outweigh the cost of intervention. Putting aside those financial and political arguments, let’s focus on the concept of “too big to fail” in a virtual infrastructure.

As hardware vendors continue to make dramatic leaps in processing power, it becomes easy to build a server capable of ridiculous virtual machine densities. But you should be careful, all that glitters may not be gold.

  1. Reference you’re “too big to fail” article, you’re probably right about the comment that there are no right or wrong answers, but for the sort of organisations that you describe, failure is not an option. A particularly nice solution that I’ve used for a number of organisations is a fault-tolerant server From NEC. http://www.nec-computers.com/222/products/servers/nec-express5800-fault-tolerant.htm . Nicely suited to VMWare, no special knowledge required, a great support-wrap, and no special software licences needed either.
