IBM has won a contract to provide IT services to the Bank of Ireland, taking over from the previous supplier Hewlett-Packard (HP).
Tech news site Channel Register reports that the bank had previously removed HP's name from the shortlist of prospective suppliers after its bid was rejected.
The bank instead chose IBM for the multi-million pound deal, overlooking fellow finalist HCL.
“After a detailed evaluation and assessment process over the past nine months, a decision has now been taken to proceed with a shortlist of two suppliers, IBM and HCL,” the bank had said in an internal e-mail to staff.
Under the five-year contract, IBM will be responsible for the installation and maintenance of all bank desktops, servers, mainframes, local area networks and helpdesks, as well as provide IT support.
The Bank of Ireland has asked its staff to behave considerately with the 500 HP staff working at the bank who will affected by the decision.
