IBM Corp’s AdStar storage systems business unit has extended its disk drive product line with five new models, and is also offering its Rios RISC-based network server as an OEM product. The new 0662 family is a line of 1.0Gb 1 high, 3.5 disk drives claimed to be the first anywhere to store 1Gb in a 1 high unit using a second generation magneto-resistive head for areal density of 354M-bytes per square inch. It follows the company’s 1.6 high 0663, 250,000 of which were shipped last year according to IBM. The new one has three platters, and ship next quarter at $1,330 in evaluation quantities. The new 0632 is a line of double-density erasable optical disk drives that come in Models C2A, C2B, C2C, C2D and C2G and conform to the new ECMA standard 184. Designed for optical library and workstation environments, the 5.25 drive provides up to 1.3Gb of removable storage and is downward-compatible with 650Mb media; samples are out now at $2,950. The company also added low cost 133Mb, 171Mb, 256Mb and 342Mb 3.5 drives at $240 for the smallest, $450 for the biggest. Evaluation units will be available in April for the AT interface model, and 3Q93 for the SCSI interface model. The company has expanded its 2.5 line with 85Mb and 171Mb low-profile models with evaluation units available now at $275 and $375 respectively. And the new 7051 Power Network Dataserver high-performance, high-capacity Network File System server developed with the help of Auspex Systems Inc, Santa Clara, is offered as an OEM product from May. It is designed for workgroups requiring fast performance and large amounts of on-line data, and attaches up to eight Ethernet local area networks with storage capacities of 8Gb to 144Gb. It does over 2,000 input-output operations per second, three to five times better than the average Unix server, IBM says; it costs $170,000 with 28.8Gb disk.
