We can acquire, configure and install hardware to run virtual servers.

The concept of virutal computing, or cloud computing is the ability for one computer to run more than one operating system, and server. 


Traditional Server Purchase. if you require 10 Servers

1 Rack Unit high

Dual CPU

4 GB Ram

1 TB Hard Drive Space

With all the bells and whistles, this would cost approximately $8000 each, and take up 10 Rack units, about 1/4 of a full rack.  The total here would be approximately $80,000

With a virtualized setup, you would buy a single server

3 Rack Units High

Quad CPU with 8 cores Each

64 GB Ram

18 TB Hard Drive Space

VMWare License

The server would cost about $40,000, and VMWare costs about $35,000, for a total of $75,000, or $5000 less, and 1/3 of the space and power requirements.

The real power of Virtualization is the ability to share common resources, so you can share the pool of CPUs between all your operating systems, and the ones that are the busiest would just be given more.  When a system is not using the CPU, it's available for other VMs.

The utilities to control, backup and restore VMware systems are also quite impressive, including the ability to have redundant VMWare servers that would be hot-swappable backup systems.  If the main system went down, then the backup system will automatically take over, and keep the servers running.  The outage would be seconds instead of hours to replace and rebuild a production server.

System Mirroring uses special order hardware that will take over the processing in case of a system failure.
