- Disk space can be increased as required without even the need for a reboot. Hugely beneficial if growth is anticipated.
- Additional servers can be created within a very short time as demand requires.
- Provides instant resilience as iservers will fail over onto other iserver hosts should there be a hardware failure of one of the physical hosts.
- Console access via the VMWare tools.
- As storage is on the SAN, adding servers or moving to a physical server is very straightforward as the data itself is never changed.
- We can offer the ability to have additional machines at no charge for short periods for test, development or patching (subject to licensing requirements).
VMWare is a ‘Virtualisation’ system - Virtualisation is an abstraction layer that decouples the physical hardware from the operating system to deliver greater IT resource utilisation and flexibility. VMWare runs as an application on a proprietary operating system, and VMWare instances or iservers can run either a Windows 2003 server or Linux operating system.
Virtualisation allows multiple virtual machines, with heterogeneous operating systems to run in isolation, side-by-side on the same physical machine.
Each virtual machine has its own set of virtual hardware (e.g., RAM, CPU, NIC, etc.) upon which an operating system and applications are loaded. The operating system sees a consistent, normalised set of hardware regardless of the actual physical hardware components.
Virtual machines are encapsulated into files, making it possible to rapidly save, copy and provision a virtual machine. Full systems (fully configured applications, operating systems, BIOS and virtual hardware) can be moved automatically within seconds, from one physical server to another for zero-downtime maintenance and continuous workload consolidation.
