It has started. All over the internet there’s a battle going, to command mindshare in relation to the virtualisation space. Microsoft and Citrix are making a full frontal attack on VMware’s dominance. Broadly speaking, the rhetoric goes some thing like this:

The vendor story

Microsoft – “We have a complete end to end management solution for all your assets both physical and virtual. Why invest in a point solution such as VMware when we can provide all of the important features at a fraction of the cost ? Our hypervisor is more efficient and smaller,  is architecturally superior and has the features that most customers need. The hypervisor is a commodity and the important elements in a virtualisation solution are really the management toolset.”

Citrix – “We have the most cost effective hypervisor on the market offering all of the really relevant advanced features that are missing from Microsoft, but provided by VMware, for an expensive premium.  Our technology set provides an integrated solution around virtualising, not just servers, but desktops and applications too. Our core product has strong pedigree in supporting non MS O/S and our partnership with MS guarantees the best all round fit no matter what server O/S you wish to virtualise.”

VMware – “We own this space, with a ten year track record and the most advanced product set that is available on the market today. Our hypervisor is the most cost effective because advanced features such as: VMotion, DRS, Host mgt and memory over-commit, provide a consolidation ratio which our competitors can only dream about. In fact, some of them haven’t shipped a product yet. We manage your complete virtual infrastructure from a single interface without the complexity of multiple consoles and technologies. Our reliability is legendary and our track record in solid dependable code release is enviable across the industry.”

Who has the answers?

• So as a customer what do you do?
• Who do you believe?
• Which vendor has the answers for your environment or your unique set of circumstances?

<Shameless Plug>
Of course, all of the vendors have valid points and they are all in a way correct. It really is a minefield trying to figure out the right infrastructure technology to use and manage your environment. What you need is a trusted advisor, an organisation with a unique field of vision across all the main infrastructure technology vendors who stands independently and can offer you the right advise based on your requirements without prejudice.

Often, the correct solution does not sit with a single vendor.  If I look at some of our recent projects, there is a common thread based on best fit, not vendor fit. We recently commenced a project to virtualise the server infrastructure of a local building society with branches throughout the country. The customer had diverse requirements in terms of desktop management, application deployment and a desire to improve their disaster recovery capability and at the same time reduce server footprint. In the end we deployed Citrix XenApp, Microsoft System Centre Ops Mgr, Softgrid and VMware ESX based on these requirements.

Make sure you choose wisely

Make sure when looking for a technology partner they have  a broad view of virtualisation and a track record in multi-vendor deployment. Rarely, if ever, does one size fit all.

Dublin, Ireland, dateline…SIAC, one of Ireland’s major construction groups, has chosen Novosco to design, implement and support its new virtualised and mission-critical infrastructure catering for the industry’s ever-changing IT requirements.

This dynamic computing environment, implemented by Novosco, will provide SIAC with a flexible and resilient backed infrastructure and will allow the construction leader to enjoy the benefits of a virtualised environment, including ease of management, increased server utilisation, increased availability and recoverability, as well as simple and effective disaster recovery.

“From the outside, the construction industry looks very traditional, however it is in fact large scale engineering at its most agile,” says Eamonn Buckley, group IS & T manager for SIAC Construction Ltd.

“Construction sites are in effect once-off factories with portacabins sometimes housing up to 50 staff with desktops. SIAC, one of Ireland’s largest construction companies, has over 500 IT users at locations ranging from a site office in Inishmean to a steel plant in Brighton.”

The solution enhances resilience and availability at SIAC’s primary site by utilising an ESX HA and DRS cluster which is back ended with a fiber-attached EMC storage array. This platform protects against single component failure and server failure and in addition provides for the most optimal use of server resources at the primary site.

Using the features of VMware VI3, live servers can be moved from one piece of server hardware to another to facilitate maintenance as well as to make maximum use of server resources.

Eddie O’Rourke, Sales Director with Novosco, was quick to point out the benefits of the project, “SIAC have managed to reduce the physical server footprint of their production infrastructure from 30 down to 3.  This has a dramatic and positive impact on the total cost of ownership of their IT infrastructure as a whole.”

“The entire swap out of SIAC’s enterprise Windows servers was achieved within six months, including Exchange and Active Directory upgrades, with a business impact of less than two hours.  In addition, by using live migration technology, production servers never need to go offline, so routine maintenance can be carried out during normal working hours.  This was a strategic project, meaning that the majority of SIAC’s server infrastructure now runs on VMware, including mission critical systems such as ERP and email messaging.  We hope to see the solution pay for itself within nine months”

All servers are now resilient using VMware’s High availability features. VizionCore delivered the back-up solution and the two-hourly replication solution to the DR site.  DR testing of key functionality such as Exchange is easily achieved by bringing up the replicated Exchange server on the DR site within a non-live virtual switch.  VMware VirtualCenter also delivered the added benefit of an excellent remote management tool for SIAC servers.

At the DR site, where the emphasis is on recovery in the event of a disaster, a single ESX host with another EMC CX SAN is implemented. This DR implementation was designed to provide enough storage to house Virtual machine images and allow SIAC to take advantage of replication facilities while also providing SIAC with an environment that can be used to test and develop for future services. As virtual machines were encapsulated into a small number of files, backup and recovery was simplified.

For the purposes of Disaster Recovery, copies of the virtual machine files are required at an offsite location. esxReplicator allows the replication of live virtual machines from one ESX Host to another without the need to maintain a live virtual machine on the destination saving on licensing costs and providing a simple, effective and controllable DR model.
