Amdahl Corp has brought forward the vital availability of an implementation of IBM’s Enterprise Systems Architecture on its IBMulators to September from the fourth quarter of this year, but only on the 5980 models – it is promising to ship ESA for the flagship 5990s only by the end of this year. The new models are designated 5980E, and will be demonstrated at the company’s Sunnyvale headquarters on August 1 and 2, with demos of the 5990s set for October. All standard and optional IBM features will be standard on the Amdahls, and field upgrades to ESA will be free, starting in the fourth quarter on the 5980Es and January for the 5990s. Amdahl also moved to alleviate users disk drive problems by bringing out the 6110 High-Performance Storage subsystem, a semiconductor storage system that is shareable among several host systems for critical, highly active, on-line data. The 6110, storing up to 1Gb fills a performance gap between main or expanded processor storage and cached or standard disk. Amdahl also claims that it can also improve the speed and consistency of response times and eliminate excessive systems tuning. The 6110 provides nonvolatile, permanent storage and has a maximum aggregate data transfer rate of 36Mbytes-per-second, and a Shared Spaces feature enables up eight input-output operations to one or more logical volumes concurrently. The 6110 access time is 0.2mS, 80 times faster than magnetic disks, and a modular, dual bus architecture increases reliability by minimising single points of failure. There are duplicate access paths, duplicate power supplies, back-up microdisks, and battery back-up to ensure maximum data availability and preserve data integrity in the event total power loss. It attaches to all 370s with data streaming channels running at 3.0Megabytes-per-second or 4.5Mbps and comes in four models. The 6110-10 and 6110-20, each with four storage adaptors, provide four and eight channels to host processors. The 6110-30 and 6110-40, with eight storage adaptors, offer 12 and 16 channels respectively. Prices start at $140,000, with shipments due to start fourth quarter 1989.
