Virtualisation Technology and VMware
Virtualisation Technology Explained The VMware Virtual Infrastructure is a software abstraction layer that decouples the physical hardware from the operating system to deliver greater IT resource utilisation and flexibility. VMware Virtual Infrastructure enables the creation of multiple secure virtual machines on one physical machine. Each virtual machine has its own set of virtual hardware (eg, RAM, CPU, NIC, etc) upon which an operating system (OS) and applications are loaded. The OS sees a consistent, normalised set of hardware regardless of the actual physical hardware components. Virtualisation is a form of partitioning tat allows multiple virtual machines, with heterogeneous operating system to run in isolation, side by side on the same physical machine. Virtual machines are encapsulated into files, making it possible rapidly to save, copy and provision a virtual machine. Full systems (fully configured applications, operating systems, BIOS and virtual hardware) can now be moved, within seconds, from one physical server to another for zero-downtime maintenance and continuous workload consolidation.
Benefits of Virtualisation Partitioning v Multiple applications and operating systems can be supported within a single physical system. v Servers can be consolidated in virtual machines on either a scale-up or scale-out architecture. v Computing resources are treated as a uniform pool Isolation v Virtual machines are completely isolated from the host machine and other virtual machines. If a virtual machine crashes, all others are unaffected. v Data does not leak across virtual machines and applications can only communicate over configured network connections. Encapsulation v Complete virtual machine environment is saved as a single file; easy to back up, move and copy. v Standardised virtualised hardware is presented to the application, guaranteeing compatibility.

Production Server Consolidation
Server Consolidation Solution Benefits v Increased operational efficiency by improving system management and reducing system complexity. v Reduced Total Cost of Ownership (TCO) by maximising server utilisation and uptime. v Reduced acquisition costs by 63%. v Reduced annual maintenance and operational costs by 66%. v Improved resource management by allowing every virtual server to obtain guaranteed CPU, memory, disk I/O and network resources. v Fewer service interruptions by moving virtual serves across a pool of machines using VMotion.
Disaster Recovery
Disaster Recovery Solution Benefits v Application and hardware independent disaster recovery plans. v Enjoy more complete disaster recovery plans by increasing application coverage, recovery testing and process automation. v Reduced hardware and maintenance costs by 70% since identical hardware is not required for reliable recovery. v Faster and more efficient disaster recovery of applications and data encapsulated into virtual machines. v Consolidation of failover hardware with little or no reduction in level of protection.
High Availability (HA)
High Availability Solution Benefits v Maximum server uptime and increased productivity and satisfaction of end users. v Increased application and service coverage. v Reduced hardware redundancy by running on many-to-one clusters and clustering between physical and virtual machines. v Save 26% on the acquisition costs. v Save 45% on the maintenance costs. v Save 72% on the operational costs. v Recovery of failed systems in seconds not hours.
Development and Test – Infrastructure
Development and Test Solution Benefits – Infrastructure v Improved quality and reduced risk of rolling out new applications by shortening development cycles and doing more rigorous testing. v Reduced provisioning times for new applications to tens of seconds instead of hours or days. v Faster development cycles and reduced configuration time for complex testing projects by enabling centralised libraries of virtual test environments. v Lower TCO and simplified server management while cost-justifying higher quality server hardware. Reduced development system acquisition costs by 48%.
