Virtualization

Virtualization is changing the industry in unprecedented ways. Questivity has a strong prsence in this market and has the best portfolio of solutions in this area.

Questivity offers the following Virtualization solutions.

VMWare Virtualization

Success brings with it competition. Whilst there are other sources of Server Virtualisation software, we believe that there is only one real choice for the corporate datacentre at this time. Only VMware products offer the performance, reliability and comprehensive feature-set that Virtualised Infrastructure demands. Other products show the hallmarks of their origin as simple multi-boot or compatibility solutions in their lack of integrated central management capability, absence of broad hardware compatibility or poor performance. VMware VirtualCentre demonstrates some of the markets most groundbreaking technology, with features such as fully centralised monitoring, reporting and alerting and the seminal VMotion – the ability to move running virtual machines between host hardware in real time. These are defining requirements for zero-downtime maintenance and reduced ownership costs. Open Standards play an increasing role in the protection of IT investments. VMware leads the field in creating an open standard for virtualization products. As VMware product continues to develop open standard support with leading Hardware and Software manufacturers, this will bring with it increased compatibility, near-native performance levels and entire infrastructures that carry the “Certified Ready for Virtualization” mark. As a VMware Professional Partner, Questivity can provide your business the most trusted advice and technical expertise to implement this technology using VMware based solutions.

Exchange Virtualization

This is driven my Microsoft and specific to the Exchange Server. The Hipervisor Virtualization SW module is not so varsatile for large data centers and is limited in functionality compared to the VMWare suite of solutions. But still it is being adapted rapidly in centers where Exchange Server is heavily deployed

Unix Virtualization IBM

The Unix virtualization market is primarily driven by IBM. Quesivity provides all IBM Virtualization Solutions.

Linux Virtualization

Cisco Virtualization

Cisco is making a strong push in the Virtualization market in partnership with VMWare. Questivity has a special focus and advantage in this area being a Cisco and VMWare channel partner.

SAP Virtualization on VMWare

This is a very strong and growing market. Questivity is again uniquely positioned to provide the best solutions being a SAP channel partner VMWare partner.

VMWare Virtualization

Questivity provides an effective virtualization design based on:

Compatibility
The behaviour of the virtual environment, as seen by the operating system and any application, must be indistinguishable from the equivalent physical environment.

Isolation
When more than one process accesses the same physical resource, the resource must be offered up as if it were dedicated to each application. A failure in any one application or processing environment must not be allowed to affect any other. Security, viral or other threats to operations must be totally compartmentalised and contained.

Encapsulation
An entire virtualised server and its applications should be represented by a small, simple set of disk-based files. This allows for good scalability and simplified management.

Hardware Independence
In a truly virtualised environment there must be no direct dependence between applications and the underlying hardware. It must be possible to change or replace the hardware at any time

Practical benefits of a implementing a virtual infrastructure include:

• Improved utilisation of physical resources, servers and storage, means that less hardware is required to deliver a given processing capability. This reduces capital expenditure, datacentre space and operating costs.
• Virtualisation creates a common layer of control over underlying devices from different manufacturers. Centralised systems management can be performed faster, more easily and with fewer resources.
• Managing representations of complete physical systems in software greatly increases the scope and potential of remote administration and deployment.
• Physical processor and storage capacity can be increased or re-allocated without disrupting data processing operations.
• Virtualisation opens the door to alternative and complementary techniques for achieving high availability and disaster recovery.
• Instances of virtual servers and their applications can be cloned and used as templates to allow agile businesses to deploy software and servers rapidly, anywhere in the world.
