| MORE DATA STORAGE
- FEWER DISKS
MultiVolume provides additional
data storage by creating multiple volumes on the SCSI drive. One to 80 volumes can be stored on the disk,
limited by disk capacity. The panel-mounted thumbwheel switch
allows operator selection of the active volume. Changing the
thumbwheel switch during operation has the effect of spinning
the drive down, removing the disk, exchanging it with another,
and spinning the drive up. MO disks are available in 128 MB
to 540 MB capacity - Jaz disks are 2 GB, with standard SCSI
hard disks providing additional capacity for more volumes
and larger disk drives.
SOLID STATE DISK - FULL-DISK CACHING
The AEM-6C includes Full-Disk Caching. The
entire drive image is held in cache memory. Changes in the
cache memory are continuously transferred to the SCSI storage
device, which can be a hard disk or Magneto Optical. Full-Disk Caching also provides a faster performing
emulation. Seek times, head switching and blocking times are
eliminated. Data is available instantly, providing 30% to
50% faster operation than the original drive.

Edge “Control” connector and “Data”
connector. Connectors are plug-compatible with the original
cables.
LOW MAINTENANCE - RELIABLE OPERATION
The AEM-6C uses SCSI disk drives for low
maintenance operation. Drives are rated in excess of 300,000
hours MTBF and up to five years of continuous operation. Drives
appear defect-free to the host computer.
REDUCED POWER, COOLING, and WEIGHT
The AEM-6C uses significantly less power
and requires less cooling than the original. A modern switching
power supply replaces the original, heavy analog supply. Power
consumption is reduced from over 400 Watts to 29 Watts; weight
of the drive is reduced to 29 lbs!
