Organizations that have fully embraced virtualization are buying host-class servers to put their VMs on. This equipment is “richer” in its configuration, with more processing power, more memory and higher quality components than the typical server designed for a single application. This gives these host-class servers the potential to replace dozens of legacy servers, along with a higher price tag. The return on investing in a highly dense VM architecture is a reduction of these more capable but costly servers.
This is an excerpt from our exclusive white paper “Maximum VM Density Requires Optimal Storage Networking and Management" and is available to anyone that registers for our on demand webinar about designing dense virtual environments featuring experts from Storage Switzerland, Brocade and VMware.
Beyond the sheer cost savings from deploying fewer host-class servers, there are also savings to be found in reduced power and data center floor space consumption, as well as a better use of storage resources. When properly designed, most virtual architectures can at least triple the number of VMs per host-class server. That means the reduction by 1/3 the number of physical host servers in the environment as well as the elimination of all the “accessories” that would have gone in those servers like RAM, storage and network connections. These are just the hard costs, still to be factored in is the reduction in administrative needs.
The key though is to build a storage architecture that is designed to support this dense level of VMs. But as Storage Switzerland discusses in its latest white paper “Maximum VM Density Requires Optimal Storage Networking and Management” the modern storage network needs more than a speed boost. It must provide a bandwidth increase in a way that assures application performance remains consistent and predictable.
In dense VM environments, predictability of performance is more important than peak performance. This requires a reliable, next generation storage network and the ability to “see” end-to-end how that architecture is holding up as well as to be able to utilize trending data to plan for future performance problems before they arise.
