【Fujitsu】FUJITSU New M-1000 Series

Fujitsu released three new model groups (M-1900, M-1700, and M-1500), following the M-1800 model group, under the generic name “new M-1000 series.” Fujitsu announced the model groups in May 1994, which were positioned as global servers that incorporated client-server designs with conventional mainframe functionality.

Features of the new M-1000 series:

(1) Dramatic cost-performance improvement and broad performance lineup
Cost performance was two to five times better than that of the M-700 series. The M-1900 model group covered a performance range of about 11 times from smallest to largest machine; the M-1700 model group, about a 7-fold range; and the M-1500 model group, about a 10-fold range.
(2) Enhanced support of client-server features
  • Standard equipped with a LAN controller
  • Supplied with PowerAIM, a new middleware package with client-server technology
(3) Data compression features and the new OCLINK*1 optical channel
(4) (M-1500 model group) Made more affordable with CMOS*2 and COF*3 technologies
The M-1500 model group used 0.5-micron CMOS technology and high-density MCM.*4 COF technology allowed the mainframes to house 3.5-inch magnetic disks.
*1. OCLINK: Optical channel link. Fujitsu’s own storage-connection interface standard for high-speed data transfers with storage units. The standard’s maximum transfer speed was 17 MB per second and storage units could be located as far as 9 kilometers away.
*2. CMOS: Complementary metal oxide semiconductor.
*3. COF: Convert storage facility. An emulation unit built in the CPU that converts disk storage formats. With the unit in place, the CPU saw new compact magnetic disk units (which used a fixed-length block format) as the magnetic disk units (which used a variable length record format) used on mainframes. In this way, COF allowed Fujitsu to use cheaper and newer disks in its M-1500 model group.
*4. MCM: Multichip module. A module that mounts multiple LSI chips on a thin-film ceramic substrate. Performance gains can be realized from the MCM’s high-density mounting. The MCMs used with the M-1500 model group cut the mounting area to one-sixth of the area needed otherwise and doubled the machines’ performance.
