IPL Systems Inc, Waltham, Massachusetts is taking on IBM Corp with what it claims is the first 9337-compatible diak array subsystem for AS/400 users. The 7737 Disk Array offers users a choice of RAID implementations in one unit, with RAID 0 and 1 implementations available immediately and RAID 5 planned for the third quarter. By pressing a button on the front display panel, users can choose the IBM 9337 mode they want to emulate, and the level of protection they require and the 7737 can be configured for full compatibility with IBM’s 010, 020, 110, and 120. Changing from one configuration to another does not need further hardware. It costs $42,000 fully configured.
