Hitachi Data Systems Introduces High-End Coupling Facilities.SANTA CLARA, Calif.--(BUSINESS WIRE)--April 15, 1996--Hitachi Data Systems (HDS) today announced the HDS Voyager Coupling Facility Offerings, a series of products designed to support users of the Parallel Sysplex architecture. These offerings enable MVS/ESA See MVS. MVS/ESA - Multiple Virtual Storage systems and applications to participate in a Parallel Sysplex environment, and support cross-system communication, synchronization, locking, workload sharing, data sharing and system management of Parallel Sysplex participants. Coupling facility technology offers the best solution for read/write data sharing among two or more MVS systems. It provides high-speed locking, caching, and message list services between coupling-capable S/390 processors running MVS/ESA version 5 or above, including OS/390. Using this technology, different data management systems can communicate and directly share data across all coupled systems. To accommodate varying customer requirements, the offerings allow three different coupling implementations: HDS Voyager Coupling Facility Series (VCF) The first implementation is a suite of 10 processors for the VCF. Models range from a one-way to a 10-way, with up to 8GB of memory. Based on CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology, each VCF processor can be physically linked to MVS systems via Inter-System Coupling Channel (ISCH ISCH Interstitial-Cell-Stimulating Hormone (Same As LH) ISCH Input Syntax Character (Alcatel) ) coupling links to be the heart of a Parallel Sysplex. Voyager Coupling Migration Facility (VCMF VCMF Vancouver Chamber Music Festival ) The second implementation, VCMF, offers emulation of ISCH coupling links for testing Parallel Sysplex within a single platform on HDS GX 8000, Skyline, and Pilot processors under Multiple Logical Processor Feature (MLPF). It enables users to take advantage of coupling facility capabilities without incurring any new hardware costs. Voyager Coupling Code (VCC) in LPAR (Logical PARtition) A logical segmentation of a mainframe's memory and other resources that allows it to run its own copy of the operating system and associated applications. LPARs are caused by special hardware circuits and allow multiple system images to run in one machine. Mode The third implementation, VCC, means that Hitachi software can implement coupling facility functions in a Multiple Logical Processor Feature (MLPF) logical partition (LPAR) on a Skyline or Pilot processor allowing work to run concurrently in other logical partitions. A standard feature in all HDS Skyline and Pilot Series processors, this mode is appropriate for environments that do not demand a dedicated coupling facility.
