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 vector stencils library "Network hardware" contains 27 clipart images and symbols of network equipment for drawing computer network diagrams.
"Networking hardware may also be known as network equipment or computer networking devices. Units which are the last receiver or generate data are called hosts or data terminal equipment.
All these terms refer to devices facilitating the use of a computer network. Specifically, they mediate data in a computer network. ...
Typically, networking hardware includes gateways, routers, network bridges, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, modems, ISDN terminal adapters, line drivers, wireless access points, networking cables and other related hardware.
The most common kind of networking hardware today is a copper-based Ethernet adapter because of its standard inclusion on most modern computer systems. Wireless networking has, however, become increasingly popular, especially for portable and handheld devices.
Other hardware prevalent in computer networking includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.
Taking a wider view, mobile phones, PDAs and even modern coffee machines may also be considered networking hardware. As technology advances and IP-based networks are integrated into building infrastructure and household utilities, network hardware will becomes an ambiguous term owing to the vastly increasing number of "network capable" endpoints."

The vector stencils library "Computer peripheral devices" contains 18 clipart images of computer peripheral devices and equipment for drawing network diagrams.
"A peripheral is a device that is connected to a host computer, but not an integral part of it. It expands the host's capabilities but does not form part of the core computer architecture. It is often, but not always, partially or completely dependent on the host.
There are three different types of peripherals:
(1) Input, used to interact with, or send data to the computer (mouse, keyboards, etc.).
(2) Output, which provides output to the user from the computer (monitors, printers, etc.).
(3) Storage, which stores data processed by the computer (hard drives, flash drives, etc.)" [Peripheral. Wikipedia]
