At McDonach Consultancy & IT Support Services our team of highly experienced engineers are amongst the leading exponents of virtualisation strategies. These diverse strategies are characterised as follows:
Server Virtualisation enables different operating systems and applications to run, in safety and isolation, concurrently on the same physical hardware. The virtualisation software layer (ESX Server, Citrix Xen Server) allows operating systems and applications to be consolidated and run on a mix of hardware, and to move operating virtual servers between host physical servers on-the-fly. The virtual servers can be managed as if hosted on a single, standardised hardware platform.
Storage Virtualisation Storage
Virtualisation is the process of pooling physical storage from multiple devices into what appears to be a device, which can then be managed from a central console. Storage virtualisation is commonly used in Storage Area Networks (SANs) such as the LeftHand Networks NSM 4150. Storage virtualisation helps the administrator perform backups, archiving, and recovery more easily, and efficiently, by disguising the actual complexity of the SAN.
Desktop Virtualisation allows the hosting of multiple virtual desktop environments on a single server. In effect this allows users to access their desktops remotely through a thin client application such as Citrix Presentation Server or VMware’s VDI technology.
Application Virtualisation: Application virtualisation is the practice of running software from a remote server rather than on the user’s computer. This offers considerable flexibility in terms of software deployment on the desktop because the application need not be installed locally, but can be accessed and run using the servers resources.
Utilising this innovative technology offers a number of benefits including:
Reduced Server Sprawl: By consolidating your servers and storage in a virtualised environment you can significantly reduce the quantity of physical servers and storage required.
Reduced Costs: Consolidating your servers not only reduces the number of physical servers and related hardware required but also additional costs associated with this hardware such as space, cooling, power consumption and support \maintenance of your IT infrastructure.
Reduces your Company’s Environmental Impact: One of the advantages of virtualisation is the reduction in number of physical servers and related hardware. This automatically reduces the consumption of other resources such as power consumption and has a direct impact on your company’s carbon footprint.
Improved Disaster Recovery and Business Continuity Processes: Taking advantage of virtualisation technologies such as virtual imaging, cloning, replication and snap- shotting, can help you implement a comprehensive disaster recovery and business continuity plan, which can be easily scaled and maintained.
Improved Desktop Manageability and Security: With virtualisation technology you can deploy, manage and monitor secure desktop environments regardless of whether end users are connected to your network or are working remotely.
