IBM Corp yesterday duly announced new releases of its MVS/ESA, VM/ESA and VSE/ESA operating systems and began the process of differentiating its Summit processors from the 3090-derived ES/9000s. The 4.3 release of MVS/ESA is claimed to improve client-server, storage and systems-management support. The 1.2 release of VM/ESA is claimed to offer enhanced systems-management capabilities and improved application performance. And VSE/ESA 1.3 is claimed to bring VSE users into the ESA world as equals rather than poor relations, supporting 31-bit addressing. A new Escon Multiple Image Facility enables Escon channels to be shared among logical partitions of a processor that uses PR/SM, and a new Escon basic mode support is intended to simplify and cut the cost of implementing channel-to-channel communications between the ES/9000 processors.
