VMware vSphere™ 4 is the industry’s first cloud operating system, which uses the power of virtualisation to transform datacenters into dramatically simplified cloud computing infrastructures and enables IT organizations to deliver the next generation of flexible and reliable IT services, using internal and external resources, securely and with low risk.

Stack Data Solutions is proud to have achieved Enterprise Focus Partner status with VMware, reflecting our investment and training in the best of breed virtualisation technology. This status means that we work directly with VMware to evaluate, consult, design and deploy even the most advanced solutions.

What is Virtualisation?

Virtualisation is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. Today’s powerful x86 computer hardware was designed to run a single operating system and a single application. This leaves most machines vastly underutilized. Virtualisation lets you run multiple virtual machines on a single physical machine, sharing the resources of that single computer across multiple environments.

How Does Virtualisation Work?

VMware virtualisation works by inserting a thin layer of software directly on the computer hardware or on a host operating system. This contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently. Multiple operating systems run concurrently on a single physical computer and share hardware resources with each other.

Why Choose VMware?

VMware is the worlds leading virtualisation provider, offering the most trusted and reliable platform for building internal cloud infrastructures and federating to external clouds.

Vmware’s Hypervisor is a robust and reliable foundation to any virtualisation project. Launched in 2001 and now in its fourth generation, VMware ESX/ESXi has been production-proven in tens of thousands of customer deployments all over the world. Other hypervisors are still version 1.0 products, unproven in production datacenters and lacking core capabilities needed to deliver the reliability, scalability, and performance that customers require.

Vmware has a vast range of virtualisation features that can suit any company of any size. Small business’s that need high availability, performance and the reliability of VMware can achieve this with cost-effective packages designed for small IT environments, while Mid-Size & Enterprise Business need an increased level of IT control through service level automation and management features that VMware has to offer.

vSphere 4 Features

The following are the main features of vSphere 4. Click on the title of each VMware feature for more information.

VMware VMotion

Live migration of virtual machines from one server to another without disruption to users.

VMware High Availability (HA)

Continuous monitoring of servers in a pool and automated restart of virtual machines on alternate servers in the event of hardware failures. Also automated restart of virtual machines in the event of OS failures.

VMware Distributed Resource Scheduler (DRS)

DRS continuously monitors virtual machines and physical servers to optimally align compute capacity to application requirements based on business priorities.

VMware Distributed Power Management (DPM)

DPM optimises DRS clusters for the lowest possible power consumption.

VMware Fault Tolerance

Provides zero-downtime and zero-data-loss continuous availability in the case of hardware failures.

VMware Update Manager

Automates patching for ESX hosts and select Microsoft and Linux virtual machines.

VMware Hot Add

Allows CPU and memory to be added to running virtual machines without disruption or downtime. Allows virtual HBAs and NICs to be added to or removed from virtual machines without disruption or downtime.

VMware Data Recovery

Provides backup to disk and simple recovery at a file or image level for small environments.

VMware vNetwork Distributed Switch

Provides a central datacenter level aggregated control point for virtual machine networking. Enables the use of third party virtual switches such as Cisco

Nexus 1000v in vSphere environments.

VMware Storage VMotion

Live migration of virtual disks from one storage location to another without disruption to users. Now with new simple administrator interface.

VMware vStorage Thin Provisioning

Defers the allocation of storage to virtual machines until it is needed. Uses monitoring and alerting capabilities to trigger proactive procurement of storage.

VMware Host Profiles

Allows creation of “golden” profiles of ESX hosts and their application to existing or new hosts.
