Virtual Server Hosting

Server Virtualization adds a layer of software (a “hypervisor”) between the hardware and the operating system. The hypervisor allows several operating systems, and related applications, to run on the same hardware. The DIS virtual servers feature VMware.

Without virtualization, 95% of Windows servers use less than 20% of their processor cpacity. Allowing one physical server to host multiple virtual machines delivers significant cost and time savings.

DIS Server Virtualization also offers new, efficient ways of managing, moving and maintaining applications through VMware “clusters.” For example:

* Provision new servers in hours rather than weeks
* Easily migrate to new hardware
* Take “snapshot” backups that allow return to an earlier configuration, in case upgrades turn out to be problematic
* Integrate with other DIS common services
* Achieve additional cost savings

DIS Virtual Server Hosting uses the VMware hypervisor to set up individual, virtual central processor units (CPUs), thereby increasing processing capacity in each server. The virtual VMware Center monitors each virtual server, adjusting and balancing workloads as needed. Balanced workloads can then function dynamically and without disruption.
