David Herranz, head of Consulting Services and Infrastructure, Dell Spain.
Any employer should have heard of virtualization , however you may not have understood exactly how it can help boost productivity and save money.
Now more than ever, companies are looking at their information systems assistance necessary to reduce costs and align information systems with business strategy.
Under normal conditions, is a proven fact that companies devote 70% for IT budget on keeping systems running, and only 30% was spent on innovation and improving infrastructure.
However, the current situation requires postpone projects and possibly reduce costs, which means that the 30% previously mentioned disappears from our budget. The obvious question is, how I can innovate and maintain a strategic IT policy for the company and at the same time reduce the expense? The answer is simple, reduce maintenance costs, (the famous 70%), and use the difference to innovate.
intelligent data center
To carry out the reduction of costs in the maintenance of data processing centers, they must have certain qualities that enable them to become self-sufficient and make their own decisions based on specific patterns, that is what Dell called the Intelligent Data Center.
What are the qualities of the intelligent data center?
The data center must first be capable of self-monitoring, then be able to, thanks to the self diagnosis, dynamically adapt to new events, new workloads or failures in any of its components, for example.
For this, the data center must be designed to deliver the performance and service levels and be flexible enough for future growth and needs of our business. In short, be scalable in all possible dimensions . Of course, should be designed to protect data, in any case the flexibility should not compromise the assets of the company.
Finally must be efficient in every way, but highlighting energy efficiency. As data, over half of English companies have already launched, or plan to do so soon, "a plan of action to reduce energy consumption computer systems. Do not forget that the energy consumption of a server 3 or 4 years old can be up to 75% higher than an eleventh generation Dell server.
The facilitator, virtualization
autonomy in this context by the data center, all components (such as applications, operating systems, hardware, processes) must be extremely efficient and time designed to work together.
In a virtualized environment is not common practice to link a server application and the reasons are many and varied. Do not forget the maxim that dependence creates complexity and therefore not relying creates flexibility and simplification.
short, this concept is applied when a data center virtualization, the dependence disappears server / application flexible resources to the point where the physical server and storage system they become a pool of resources at our disposal.
But what is virtualization?
The simple explanation is that virtualization lets one computer act as server or several. Instead of running your applications on separate servers, virtualization software can run several different applications on the same server simultaneously.
virtualization software allows a server to be divided into several 'virtual machines'. This means that a company may only need a server to use all your applications, while using conventional servers need to run the same applications at the same time on different servers.
Take an example in a typical work place - a server physicist might act more or less as three virtual servers, each running a different application separately (eg, Web server, e-mail server and server system or file manager), each as if they were being implemented in their own physical server.
Each virtual server acts completely independently of each other, so if an application fails, the other applications that are being implemented in other virtual servers, would not be affected. What do we get? The benefit of three servers for the price of one. It is estimated that the current average ratio of virtualized servers is in 6, (6 virtual servers per physical server) and this ratio is expected to shortly pass 8.
Virtualization Utilities
addition to the logical partitioning, virtualization offers many benefits associated with, beyond the under-utilization of hardware resources. Some additional benefits can be simplified management, provisioning of new servers almost instantly, the portability of applications not supported by modern hardware, high availability and capacity of disaster recovery environments embedded in the technology of virtualization, among others.
Why interested in server virtualization for SMEs?
For SMEs time is money, and Dell can teach them how to save both virtualization. Many SMEs have already tested and are enjoying the benefits of virtualization, allowing them to adapt more quickly than their larger competitors. Virtualization allows
save more than product costs, as we have seen. Having fewer servers means less power consumption, less cooling and less maintenance, not to mention saving space in the facility.
virtualization provides business flexibility to scale computing resources without purchasing new servers. Virtualization is also an excellent tool to manage data loss and subsequent recovery because virtual machines and applications that include fast and can move easily from one physical machine to another.
Thus if a disaster in which a virtualized physical servers out damaged, virtual servers can move to another virtualized physical server without any special recovery process. The result: a massive reduction in lost time.
ACA LES DEJO
Well! this great game was very popular in App Store as sold thousands of copies ... ..
PopCap, has posted some information on its highly successful sales vs. Plants. Zombies for iPhone and iPod Touch. The report said that the implementation has sold over 300,000 copies in just 9 days breaking all previous records in terms of profit. Many applications have been able to generate more than 1 million dollars in sales, however, many have been able to do little more than a week.
esqueAnd this game really satisfies us with its simple gameplay and challenges become more difficult each time, this gives us a good time of fun, and if you have not played download it now:
