Virtualisation

Modern IT is all about virtualisation, organisations of all sizes are now virtualising all the servers that they can to reap the benefits of massive cost savings and better disaster recovery – many are now looking to virtualise their desktops to gain even more benefits.

Benefits

Reaping the benefits

SNS can help you reap the benefits

Recent advances in hypervisor and server technology enable virtual machines to have a nominal CPU and memory performance overhead, quality of service policies that ensure they get all the resources they need and wire-speed storage and networking.

This makes it possible to virtualise even the largest x86 workloads, including Microsoft Exchange, SQL and SharePoint, Citrix, Oracle and SAP. Once applications are virtualised they can benefit from the improvements in efficiency, availability, disaster recovery and data protection.

Convincing application owners that their applications should be virtualised is often a tricky task, and SNS is well equipped to assist in this process and to help you build a virtual infrastructure that can support the most demanding of applications and their owners.

Hardware

Hardware

Choosing the right hardware

The storage array is the heart of any server virtualisation solution and it must be sized correctly to provide the capacity and performance required to ensure success – consolidating local storage onto an array based on capacity alone will almost certainly result in an under-performing virtual infrastructure.

Most hypervisors integrate very tightly with storage arrays, often off-loading storage related functions to the array to increase performance and efficiency, so choosing an array that has been optimised for your hypervisor is essential.

All modern servers offer support for hardware-assisted virtualised CPU and Memory management, these are the key to virtualising large applications – gone are the days of there being a significant performance advantage to keeping servers physical.

Data Protection

Data Protection

Virtualisation improves Data Protection

The beauty of a virtual machine is that it is just a collection of files, these files can be backed-up and restored as “images” providing full system protection without loosing the ability to restore individual files and folders.

Many systems do not require specific application agents, so agent-less LAN-free “image” backups can be performed and only when advanced backup and restore capabilities are required do application agents need to be installed.

Newly created virtual machines can be automatically backed-up and array based snapshots can create backups of 100s of virtual machines in minutes. Change Block Tracking technology enables incremental backups to be performed at incredible speeds allowing organisations to complete backups within the available window.

All in all a very compelling reason to virtualise as many applications and systems as possible.

Disaster Recovery

Disaster Recovery

Simplifying Disaster Recovery

Virtual machine files can be replicated to a recovery site and in the event of a disaster can be booted using a compatible hypervisor. No part of the recovery site’s hardware needs to be the same as the production site and the recovery site can be used for test and development systems, and can also be a fully active production site.

Testing recovery plans is straight forward as snapshot copies of virtual machines can be mounted in an isolated network and most hypervisor vendors have created tools that automate disaster recovery fail-over, fail-back, and test fail-over processes – helping to ensure the reliability of the plans.

Next-generation stretched storage technology is enabling data centre cluster technologies (i.e. VMware vMotion, High Availability and Fault Tolerance) to be performed between sites.

Monitoring

Monitoring

Meet application SLAs and ensure smart hardware purchases

One of the barriers to virtualising mission critical applications is the concern that a shared pool of resources may not provide the users with the response times they need. Often this will prevent organisations from virtualising these applications or they will be virtualised, but the hardware will be significantly over provisioned – negating one of the main benefits and pushing up license costs.

Effective virtual infrastructure monitoring is the answer – it will provide an early warning system for any applications showing signs of becoming resource constrained and help identify if any new hardware resources are required.

The net result is you can afford to run an efficient infrastructure that is not dramatically over provisioned and can be enhanced through smart hardware purchases (i.e. there is no point in adding new servers when the bottleneck is in the storage array).

Virtual Desktops

Virtual Desktops

Deliver desktops where and when they are needed

Now that many organisations have reaped the benefits of server virtualisation, they are looking at how virtualisation can help with desktop delivery.

By detaching the desktop from the physical end-point a consistent and secure experience can be delivered across the LAN or WAN, or from any Internet connected device. The experience can be delivered on desktop PCs and laptops as well as smartphones and tablets – providing a key enabler for a Bring Your Own Device strategy.

Once virtualised desktop management is centralised and changes to master images can be automatically rolled-out to all users, new applications deployed with ease and operating systems changed over-night.

The key to a successful project is to perform an extensive proof of concept to accurately determine the server and storage resource requirements for a full deployment.

    VMware DR & Data Protection for Angel Trains

    There were just too many physical servers so we needed to virtualise as much as we could and make the process as painless as possible. In addition the business could no longer be confident that in the event of a disaster it could reliably recover, we needed the process to be streamlined so we can easily test our business continuity plan on a regular basis.

    VMware Data Protection for Jephson Housing Group

    We have a diverse infrastructure and therefore have deployed a wide range of backup products, we also tried a number of free or low-cost agent-less VMware solutions, but these proved to be unreliable. Backup had become a significant drain on the department’s resources and it had become clear that we needed to consolidate onto a single reliable solution.

    VMware Data Protection for University of Westminster

    The University has been running a mix of internal and out-sourced backup solutions for many years which has worked, but there has been a clear desire to reduce administration and consolidate these into a single solution. We were clear that any new solution would need to provide us with the ability to back up and restore our VMs without the need for in-guest agents to be installed.
