IPL Systems Inc, which relocated to Maynard, Massachusetts while we weren’t looking, claims it sets a new standard in price-performance for AS/400 users with three new disk subsystems. The new Model 40s join IPL’s eight-month old ESP 7000 Series of RAID 5 arrays. The new models use 2Gb 3.5 drives to achieve the lowest cost per Megabyte in the industry, without sacrificing performance. Current ESP 7000 customers using 1Gb drives can can field-upgrade to 2Gb ones. The ESP 7000s offer 9336 or 9337 emulation, choice of RAID 0, 5 or AS/400 mirroring, controller level and read and write cache and optional customer-replaceable drives and power supplies. The 7737 and 7037 Model 40s attach to IBM’s 6500 and 6501 feature and store up to 13.6Gb – going to 15.8Gb with the 6501 feature in second quarter 1994. The 9336-compatible 7637 Model 40 stores up to 6.8Gb in one subsystem.ESP 7000 Model 40s and upgrades are available for shipment this month at prices from $30,000 for a fully-configured subsystem.
