Server Virtualization And How It Can Save Your Biz BIG Money!
There are many gains to virtualizing your servers,, but this article focuses on the three main reasons why a small business may want to look into server virtualization. You may normally associate this with much larger companies, however, it can be tremedously beneficial for smaller businesses because it can improve disaster recovery, server utilization, and reduce power consumption.
Improve Disaster Recovery
It is possible to have your business server up and running better than ever if there was a critical hardware failure on your server if that . You could potentially copy the "virtual server" file over to another piece of hardware and then install a virtual machine player such as ?VMware Player? and boot up your ?virtual? server file within minutes and have it fully functional again If this hardware problem had happened in a regular, non virtualized environment, you first, would have to address the issue on the original server before using it, or at minimum restore from backup to another piece of hardware. On average, this is not a case where one could wait on the original restore files to be copied, more oftne than not, the Operatiing System must be completely re-installed! Moreover, because you made the wise decision to go virtual, your server can be remotely backed upo and running in a short amount of time. Note, obviously that the larger the virtual server file, the longer it would take to copy the file. Notwithstanding, the time associated with a file copy against the time of a resoration or online backup is significantly less Server Utilization...Improved!
In my experience I have noticed 2-5 servers in use for most small businesses and they could really manage on much less in today's "virtualization capable" world. A lot of small businesses of this size tend to "dedicate" a server to particular Line of Business Application or function such as a Mail Server, Database Server, File Server, etc. Almost all of these servers are tapping into a small fration of their available processing ability.
Reduce Power Consumption
When you combine your servers and eliminate unneeded physical servers, you consume less energy...and save more money!. Not only is this credited to the use of less monitors, but also in the costs attached to cooling those unneeded servers. Whats more, the savings associated with reduced energy needs have been reported as high as 85%
