    PACKAGE

  • 56" 16 slot cabinet; VME bus; 22MB/sec bandwidth

    PROCESSOR

  • Cypress, 33 MHz
  • 33 MHz; 22 MIPS

    FPU

  • TI8847 33Mhz 3.8 Megaflops

    MMU

  • supports 64 contexts in memory 4 GB each

    CACHE

  • cpu has 128KB write-back cache 98% hit rate
  • the 490 does have an 4KB I/O cache
  • with IPI drives it achieves very high performance

    PERIPHERALS

  • 1/4" tape, 1/2" tape, IPI disks, CD-ROM

    PORTS

  • 2 rs232/423 ports on cpu board

    TAPE

  • tape is 150MB SCSI 1/4" tape
  • Front Load 6250/1600/800 HP tape drive
  • the HP can stream a 135MB partition in 5 minutes
  • the max 1/2" tape drives is 3, up to two
  • in one expansion cabinet. One FL tape
  • takes up the same space as 4 IPI's
  • also can accommodate 2.3 GB 8mm, CD-ROM

    DISK

  • 32 GB of Disk capacity; w/announcement of 1.3 GB
  • IPI - 41.6
  • 4GB (4 IPI's) can be put in the bottom of the
  • main cabinet; w/new 1.3 GB IPI - 8 supported for a
  • total of
  • of 10.4 GB in CPU cabinent
  • each expansion rack can have up to 16 GB
  • there is max of two expansion racks
  • the absolute max is 32 drives on the 490
  • this means that if you have 4 disks in your
  • CPU enclosure you can only have a total of 28
  • drives in your expansion racks; w/1.3 GB IPI - you can
  • have 12 disks per expansion rack (15.6 GB in each)
  • up to 4 IPI controllers w/up to 8 drivers per controller

    SCSI

  • CD-ROM comes standard; up to 2 5 1/4" devices
  • devices 1/2" tape in a single CPU enclosure

    IPI2/DC

  • there is max of two expansion racks
  • supports 3MB (1 GB) and 6MB/sec (911 MB) disks;
  • and
  • 4.5MB/sec (1.3 GB IPI); to add new 1.3 GB drive, to
  • 490
