Server Virtualization is the process of presenting a logical grouping or subset of computing resources so that they can be accessed in ways that give benefits over the original configuration. This new virtual view of the resources is not restricted by the implementation, geographic location or the physical configuration of underlying resources. Commonly virtualized resources include computing power and data storage. |

Virtual Media can keep you out of the data center and improve management, security and the overall working environment. Virtual Media addresses operation efficiency and security by enabling servers to access CD-ROMs and other storage media anywhere across the enterprise as if directly attached via the server's USB port for increased efficiency and security of the data center.

Increasing power demands and space limitations in the data center have begun to transition server virtualization technologies from luxuries to necessities. Server virtualization provides a path toward server consolidation that results in significant power and space savings, while also offering high availability and system portability. Today, vendors are building hardware and software platforms that can deliver virtualization solutions at near-native performance.

CA's vision is to unify and simplify the management of enterprise-wide IT. The rapidly growing use of virtualization and clustering in enterprise infrastructures provides a rich environment for increasing complexity. Unlike physically bounded infrastructures, the logical entities in virtualized and clustered environments are not visually apparent. Nevertheless, one needs to know what resources one has and if one is using those resources to their fullest capacity.

Management of a virtual environment presents unique challenges; many organizations do not thoroughly anticipate the differences in managing a virtual environment from a purely physical environment. Many of your existing management tools may, in fact, only be able to manage physical machines or may collapse under the sudden load of many more systems.

IT departments constantly face demands to deploy, maintain and grow a broad array of services and applications, but this has lead to server sprawl and high energy costs. Consolidation and containment solutions implemented with a virtual infrastructure meet the challenges of server sprawl and underutilization by reducing hardware and operating costs by as much as 50%.

Virtualization is a sea change from the days of one image per physical machine. And the benefits are clear, from better hardware utilization to lower costs to easier management. But while the resulting server consolidation is a good thing, it only solves half the problem. You still need to ensure that best-practice storage management is available to both your physical and virtual servers.

Virtualization does have its dangers, as it incurs greater stress on physical resources. While under utilization of CPU may be a driving factor to virtualize servers, other hardware resources may become overtaxed. Given that a host system has limited ability (depends on application) to page memory used by the guest systems, the most recognized bottleneck to address is physical memory (RAM). Options to programmatically alleviate memory bottlenecks incur performance issues when the disk is re-introduced. Another major component and perhaps less acknowledged is the disk subsystem. In many cases, depending the purpose and application of the guest/virtual systems, the disk bottleneck will be the most significant barrier to performance.
