Hewlett-Packard Co makes exceptionally full use of its partnerships these days, and has tapped Precision Architecture RISC licensee Hitachi Ltd to add functionality to its HP-UX Unix. The Palo Alto company acknowledges Hitachi’s superior skills in the fields of configurability, flexibility and high availability, and wants it to bring them to bear on HP-UX so as to enable applications and databases to continue to provide service to end users during system reconfigurations. Results of the initial phase of the project are to appear in releases of HP-UX set for later this year. Hitachi says it intends to continue the co- operation and hopes to make further contributions of technology and skills to HP-UX, and to the next-generation 64-bit Unix architecture now being developed by Hewlett in alliance with Intel Corp.
