Virtualisation Services
More than ever, it is clear that Virtualisation makes good business sense. It can help an organisation reduce costs, increase agility and make IT more responsive to the needs of the business.
Performance networks offers a complete, mainstream Virtualisation solution that leverages VMware software and Dell/HP platforms, management tools and services. This proven solution creates a path to the broad benefits of a virtualized IT environment.
Virtualisation reduces costs, improves resource efficiency and improves management
and provisioning by consolidating multiple logical servers onto more powerful devices.
VMware has developed Virtualisation software that brings mainframe-
Reducing Costs and Increasing Agility
With the advent of virtualisation it is now possible to run multiple instances of Windows servers on an individual piece of equipment. This method of working reduces the need for hardware and therefore assists in simplifying the network in a number of ways.
• Reduced hardware requirements.
• Reduced power requirements.
• Simplified management of applications.
• Rapid deployment of new servers (in the virtual realm).
• Simplified disaster recovery.
• Improved planning for upgrades and migrations.
• Simplified maintenance.
The list of advantages of this mode of operation are overwhelming and cover many of the traditionally problematic results of operating with larges numbers of Windows servers.
VMotion
VMware® VMotion™ enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity. VMotion allows IT organizations to:
• Continuously and automatically allocate virtual machines within resource pools.
• Improve availability by conducting maintenance without disrupting business operations.
VMotion is a key enabling technology for creating the dynamic, automated, and self-
VMware VMotion moves live, running virtual machines from one host to another while maintaining continuous service availability.
How is VMWare VMotion used?
VMotion allows users to:
• Automatically optimize and allocate entire pools of resources for maximum hardware utilisation, flexibility and availability.
• Perform hardware maintenance without scheduled downtime.
• Proactively migrate virtual machines away from failing or under performing servers.
How does VMotion Work?
Live migration of a virtual machine from one physical server to another with VMotion is enabled by three underlying technologies. First, the entire state of a virtual machine is encapsulated by a set of files stored on shared storage such as Fibre Channel or iSCSI Storage Area Network (SAN) or Network Attached Storage (NAS). VMware’s clustered Virtual Machine File System (VMFS) allows multiple installations of ESX Server to access the same virtual machine files concurrently. Second, the active memory and precise execution state of the virtual machine is rapidly transferred over a high speed network, allowing the virtual machine to instantaneously switch from running on the source ESX Server to the destination ESX Server.
Implementing Virtualisation
Performance networks offers proven processes for implementing Virtualisation solutions. These processes draw on best practices and established methodologies to guide you through the three key stages of a Virtualisation initiative: planning, deployment and migration, and operation
A Step by step approach to Virtualisation.
Phase 1: Planning
Identify Virtualisation candidates
Gather Inventory and performance data
Determine appropriate hardware infrastructure (Server Type, Storage, and Networking)
Determine Best fit for applications to run in virtual environment.
Phase 2: Deployment and Migration
Build and Racks, Servers, Networking, Storage.
Install Operating System and Virtualisation Software onto each Physical Server.
Deploy new applications to Virtual Servers.
Reuse or Recycle retired systems.
Phase 3: Operations
Monitor Physical servers and virtual servers.
Make any performance adjustments needed.
Performance Networks has carried out many Virtualisation Migrations for different
industries including Law firms for data protection and compliance matters, and Industrial
companies seeking to reduce the total cost of ownership within their I.T. Departments.
