The Irish League of Credit Unions (ILCU) represents 484 financial institutions across Ireland, with combined assets of 13.6 billion euros and membership of over 3 million in credit unions. Whilst independent, credit unions remain in the ownership of their members and are facilitated by common bonds to ensure that the savings of members are available to fellow members as loans. The ILCU was set up as an umbrella organisation to represent and provide joint services to the affiliated credit unions. Acting as a single consolidated body on a national level, the ILCU represents and provides expansive services including legal counsel, HR advice, joint advertising, professional services and ICT.

CUSTOM-MADE VIRTUAL ENVIRONMENT
Faced with ageing physical hardware which was becoming increasingly complicated, volatile and challenging to manage, ILCU decided it was an ideal opportunity to take a fresh look at the entire environment through server and storage virtualisation to reap the benefits of consolidation, decrease overheads and achieve a greater availability of critical business applications. Malcolm Moir, Infrastructure Services Manager at ILCU's Dublin HQ:- "Our very ethos is about providing equitable, reliable, shared & stable assets to our user base. We knew that there had to be a better way to service them with a highly available environment that also offered Disaster Recovery."

They turned to architecture advisor and Irish DataCore Gold partner, Typetec, who recommended and implemented VMware vSphere for server virtualisation to optimise the utilisation of common resources (CPUs and disks) and to readily redeploy these resources (servers and storage) when and where needed. Typetec also explained that VMware vSphere requires additional assistance to enable advanced functions such as workload migration, load balancing, fail-over and disaster recovery, and is completely dependent on highly available (HA) shared storage platform. They went on to introduce the concept of a storage hypervisor to ILCU - a portable, centrally-managed software package from DataCore that extends provisioning, replication and performance and acceleration services.

To prove the concept of what could be achieved moving away from traditional Direct Attached Storage on a Storage Area Network (SAN), Typetec took the unusual step of creating ILCU's entire infrastructure within their own internal test and development lab. A pair of DataCore SANsymphony-V nodes were tested in a dual mirrored configuration, running on standard x86 Intel hardware. ILCU were invited for an interactive hands-on briefing session using the intuitive interface of SANsymphony-V to achieve automatic failover of both path and data through the DataCore Storage Hypervisor. With concepts proven and validating customer research into some of the 8000 DataCore global customers gained, installation commenced.

HEIGHTENED SECURITY
Installation began, first consolidating the workload of ILCU's 20 physical servers into 2 HP ProLiant servers which run as Virtual Machine hosts for VMware. Two further HP ProLiant servers act as the host for the DataCore SANsymphony-V nodes acting in a synchronous mirrored pair to alleviate the fear of a single point of failure. Closing this single potential failure scenario in the Disaster Recovery process for the ILCU was a significant step in achieving a heightened sense of full security. Malcolm elaborates: "Previously, conversations with our business colleagues would centre on how Disaster Recovery should work. With the new DataCore SANsymphony-V environment, those service level conversations shifted into providing advice on how individual business continuity background processes could be optimised for each department. That's significant when you consider that assured Business Continuity has been achieved at 60% of the cost of alternative storage environments."
