Brennan IT Services was founded by John Brennan in December 2003.  John is a very experienced IT Consultant and Project Manager who has been working with customers in a variety of industries since the first IBM PCs were launched in Ireland in early 1983.


At Brennan IT Services we focus on delivering value added cost effective solutions to companies of all sizes: from those smaller companies who have no internal IT departments to larger companies who have their own internal IT resources but who have limited or no Project Management skills available.


John is currently working as IT Infrastructure Project Manager with Meteor Mobile Communications on their new Intec Singl.eView Billing System.


John worked as Project Manager on a significant IT Disaster Recovery project with Irish Life & Permanent from March 2005 to October 2007. This €7.5m infrastructure project significantly improved the capability of the business to recover from a Disaster situation by implementing a Dual Data Centre Disaster Recovery strategy for key business systems. These key systems included Oracle running on a variety of platforms including HP-UX, IBM AIX and Windows Server 2003; Exchange Server 2003 email for over 5,500 clients utilising EMC DMX SAN. Other systems include IBM mainframe and Sun Solaris plus 50 Windows Servers. That significant infrastructure project is now complete.


Over a period of 23 years with IBM Ireland John worked on IT services and infrastructure projects with various companies including ABB; Johnson & Johnson; Bank of Ireland Finance; AIB Bank; Rhone-Poulenc Rorer; Antigen Pharmaceuticals; Klopman (Tralee); Batchelors; Church & General Insurance and EBS (Branch Roll-out).  His principal role was designing and delivering IT networking and infrastructure solutions that added value to the client’s business.


During his years with IBM John received the IBM=Service Award on 3 occasions and the Professional Excellence Award as well as a number of Special Contribution awards, including a unique design award.


Following his successful completion of a BA Honours degree in Management at the Irish Management Institute, John moved from IBM Ireland to C&C Group in June 1997 as the Network Manager. He was responsible for bringing proper standards into the network infrastructure of the various trading companies within C&C Group (C&C Ireland, C&C International, Bulmer’s, C&C Wholesale, Grants of Ireland and Tayto).  John had responsibility for and managed the IT infrastructure and support services across Ireland (LAN & WAN, voice & data). He also managed and developed the partner relationship with the Groups main suppliers and ensured that all SLA’s were being met through regular communication and meetings.  This role and responsibility expanded as the number of companies increased until there were 42 sites connected around Ireland plus another large site in Italy, an office in New York and a sub-office in San Francisco.  With the network infrastructure stable, the focus of attention then moved to Business Continuity, Disaster Recovery and Security.  John developed and tested the C&C Group Business Continuity plan including Disaster Recovery for the central AS/400 systems, Wide Area Network and Internet connectivity as well as Windows Servers and Lotus Notes mail systems.


John left C&C Group in December 2003 as the C&C Group decided to outsource their IT Infrastructure to a third party.
