Having tantalised Hewlett-Packard Co sufficiently with its fault-tolerant Unix multiprocessors that it is now the beneficiary of large and growing multi-million dollar OEM business from Palo Alto, Marlborough, Massachusetts-based Sequoia Systems Inc has now seduced another heavyweight, this time from Japan. It has signed a memorandum of understanding with Sumitomo Electric Industries Ltd under which Sumitomo will become a reseller of Sequoia’s machines in Japan and some other countries, and discussions will now move on to granting the subsidiary of the chemicals giant manufacturing rights to the machines, as well as a joint devlopment on future products. No details about potential future products were disclosed. General terms call for Sumitomo to become a non-exclusive OEM customer for all current and future Sequoia systems in Japan and in other countries, on a case-by-case basis.
