IT directors should invest heavily in storage capacity when preparing for a major integration programme, Stuart Whalley, organisation and culture change manager at utility company E.ON, told last week's Tif conference.
Whalley led the database integration project when E.ON subsidiary Powergen acquired TXU Energy. The company added 60-70Tbytes of storage to create a 100Tbyte system for the project, which began last year.
Preparation was vital, Whalley and technology partner Hewlett-Packard took six weeks to map out the storage layout. He advised Tif members at the conference to overestimate their storage needs - storage capacity gives you flexibility, he said.
He also emphasised the importance of ensuring disaster recovery systems remained in synch with live systems during any major integration project.
