Data Center Virtualization – 4 rules

Information for the enterprise these days is at least as important as finances or main assets. For this reason information storage should be organized in a manner that ensures its constant availability for coworkers and end users, while guarding confidential information from unauthorized access.

However, data storage system transformation and data center virtualization is not a simple task even within one data center, especially if we take to consideration the fact that IT-administrators try their best to perform all works without interrupting the enterprise activity. Nevertheless, problems can be easily solved if you stick to 4 simple rules described below.

Simplification of virtual data storage system
First rule. Prior to beginning data center transformation it is useful to evaluate the possibility of data center virtualization. If virtualization requires creation of additional control layer for association of physical and virtual resources, single points of failure, or binding to a certain provider, or structured zones, then it will only make already complex data storage network even more complicated. The simplest and most efficient solutions are those utilizing existing system controllers for standard connection to external storage media. This allows controlling external data the same way internal data is controlled, while supporting functional capabilities and performance of given controller.

Internal and external extension
Second rule. In order for extension to make for maintenance expenses reduction, unprecedented scalability opportunities are needed. You will be better off using such solutions that are capable of extending according to system consolidation requirements demanded by more and more powerful server clusters, as well as aiming at dynamic allocation of virtual resources for data storage on a growing number of servers and applications.

Built-in security system
Third rule. With data center virtualization, IT-administrators should provide for mechanism of protecting the data from unauthorized access. Ideal data storage system security can be provided by delimiting user zones and separating control data from user data, as well as by assigning different addresses to virtual ports, which rely on the same physical ports. However, for efficient operation of these security functions they should be initially built-in to products, and not be postponed for later implementation.

Fourth rule. Applications should “see” both virtual system and the underlying physical infrastructure. Besides, data storage system should incorporate an opportunity of tracking service applications operation. The latter cannot be implemented without an integrated software tools that provide collecting data from the entire infrastructure, identify it with a server or an application, and finally output it to intuitive control panel.
These four simple rules allow creating a data center virtualization, which will provide global consolidation of resources, technologies and applications. Such virtual system simplifies IT-infrastructure and provides for protection of all data, which increases its significance for enterprise operation.
