Summary

Users of the NHHDA and EAC/AA systems requested that Elexon makes an early decision about future operating platforms for this systems, in order for Market Participants to be able to plan and budget for hardware purchases. Currently NHHDA and EAC/AA Systems are developed and supported by Elexon on Hewitt-Packard (HP) AlphaServers running on the Tru64 Unix 5. 1b operating system. These servers are being phased out by HP and, while no operational issues are expected in so far that HP will continue to support the operating system until 2011, an early decision in respect of future platforms will provide clarity to the industry. CP1187 proposes a number of potential solutions for the operating system(s) that will replace Tru64 Unix 5. 1b as the supporting platform for NHHDA and EAC/AA. After discussion by the Software Technical Advisory Group (STAG) on 25 January 2007 and an email survey the options are: HPUX, Sun Solaris and IBM AIX. There is Market Participant support for all three of these options to varying degrees and therefore Elexon requires answers to all questions about each option found on the Impact Assessment form to help the Supplier Volume Allocation Group (SVG) to make an informed decision on which option to choose.
