SIAC chooses Novosco to virtualise their production server environment
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.
