Encore Computer Corp has launched the first member of its Infinity Storage Product family, subject of the company’s agreement last month with Amdahl Corp. The Fort Lauderdale, Florida company claims the Infinity SP Model SP20 represents a breakthough in terms of pricing for the IBM Corp mainframe-compatible storage market. The SP20 is designed for IBM and other 3990/3390 or 3380-compatible mainframes, and sells for $4 per Megabyte; it will ship in volume in the third quarter. Storage is configurable from 48Gb to 440Gb. The controller uses four Motorola Inc 88100 RISC-based processors, high-density, 7,200 rpm 3.5 disk drives from Seagate Technology Inc and advanced RAID technologies developed in-house. The SP20 comes with built-in cache, expandable up to 1Gb, and including features such as Cache Fast Write, Sequential Data Striping and Concurrent Copy. Fast Write is supported via Encore’s Non-Volatile Storage option. SP20 subsystems are connected via two to eight OEMI parallel channels, with other options including Ethernet and other local and wide area interfaces under development. Following the OEM agreement announced last month (CI No 2,385), Amdahl has the option of reselling the SP20 along with Encore’s other storage products, under its own name, but has not yet signed to do so.
