With features like thin provisioning, memory transparent page sharing, and Dynamic Resource Scheduler load balancing for CPU and Memory, you are better able to fully utilize the hardware resources in your infrastructure.
Fewer servers and related IT hardware mean reduced real estate, reduced maintenance costs, and reduced power and cooling requirements. Better management tools let you improve your server to admin ratio so personnel can be more effectively utilized.
Securely backup and migrate entire virtual environments with no interruption in service. Eliminate planned downtime and recover immediately from unplanned issues.
Respond to change with dynamic resource management, faster server provisioning, and improved desktop and application deployment. Allows for virtual server mobility and flexibility of maintenance on physical hardware at any time during the day.
Deploy, manage, and monitor secure desktop environments that users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop, or tablet PC. Reduces the number of desktop images that need to be managed and provides an easy update and rollback options to reduce Operating Expense costs.
In Hardware Virtualization technology, a single processor acts as many different processors. Different operating systems can be run on the same hardware by the user or multiple users can access the processor at the same time. This requires a Virtual Machine Manager called as the Hypervisor, which regulates the processor, memory and other elements without a source code to run on the same system with different operating systems. The primary aim of this technology is to merge small servers into a single server. This enables the processor to work more efficiently. This commonly used virtualization benefits from the hardware usage. The advantage of hardware virtualization lies on the web servers. The virtual server runs on separate operating systems and is rebooted individually. Hardware virtualization is classified into three types – namely, Full virtualization, Paravirtualization and Partial virtualization. In Full virtualization, the total replica of the actual hardware is used to run the unchanged guest operating system through a software. In Paravirtualization, the modified operating system runs an unmodified software. In Partial virtualization, the software needs some changes to run.
In Network Virtualization technology, the physical networking equipment is linked to a single resource. The method of splitting bandwidth into many separate channels which are assigned to devices and servers is called Network virtualization. This technology is majorly useful when the network experiences a huge increase in usage. Network virtualization simplifies the workload for a better computing growth. The major advantage of network virtualization is the network productivity and capability. It facilitates the enterprises and business people who have a major number of users to keep the systems working all the time. Since network virtualization has separate channels, the speed of the network increases which allows the applications to work faster.
Application technology allows the user to access a particular application from a remote server but not necessarily from their own workstation. All the personal data and other features of the application are stored on the server yet the user can access it on a remotely located workstation. Technically speaking, it works as if the application is installed even if it is not. The applications are virtualized and sent to the user’s devices such as laptops, tablets, and smartphones through the server. This allows users to login into their computers at the workplace from anywhere and accesses the respective application through the internet connection provided. This virtualization isolates application layer from the bottom of the operating system and in this way applications do not have to depend on the operating system but can run in an enclosed form. This virtualization is specifically favored by businesses.
In this technology, the method of classifying physical storage from different network storage devices is done. This enables the device to function as a single storage device. This type of storage virtualization is easy for management and optimizes resource usage. This offers benefits like improving the storage management under a composite IT environment, easy updates, reduced intermission during the activity, improved storage usage, and computerized management. Storage virtualization is convenient for disaster recovery as the data on virtual storage can be copied and transmitted to other location. There are two types of storage virtualization, the block, and the file. The block storage virtualization substitutes the controllers and supports at the disk level while the file storage virtualization needs the installation of the software on the server that uses the storage to allow file-level usage.
In Desktop technology, the workstation is virtualized rather than a server. The User can access the desktop remotely and can connect to the workstation securely. This facilitates user’s ability to log in and works from anywhere. Additionally, it is well secured. Confidential data is kept safe on centralized protecting it from the threat of theft. Centralized servers reduce the cost of installing software on desktops. Management and maintenance are very easy as virtual desktops are at the same location. Since the virtualized desktop is stored in a remotely located centralized server, this virtualization is called as the client-server computing model. Desktop virtualization isolates the environment of a desktop and the physical device such as a smartphone, laptop or tablets and is configured as a Virtual Desktop Infrastructure.
