Virtualized computer center

This rack diagram example was drawn on the base of picture illustrating the article "Virtualization in general, for technicans and business people" from the Banym's Blog by Dominik Zajac. [banym.de/virtualization/virtualization-in-general-for-technicans-and-business-people] "Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources." [Virtualization. Wikipedia] "With the CPUs we have today you can virtualize up to 10 – 12 old servers to one new big machine with for example 2 x 6 core CPUs and a lot of memory. In this case you see what potential this technology has. Turn off 10 servers and run it on just one machine. That’s not the way I would do Virtualization. It’s nice to save energy but what happens if we have a problem with our one new big server? The complete organization can not work without ERP, EMail etc. and because of this we need a cluster. Such a cluster configuration looks something like this: (rack diagram example). Two big servers, a storage subsystem and a smaller management server. If you compare now the old configuration with the new one you can see there will be still made some points for energy efficiency. That’s not the only benefit you should have in focus, for the mature Virtualization solutions like VMware or Citrix/XEN exist a big number of tools and documentation to make the life easier for administrators and system managers. This safes time and brings better reaction times for your IT." [banym.de/virtualization/virtualization-in-general-for-technicans-and-business-people] The rack diagram example "Virtualized computer center" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rack Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
