Standard Features

Compactness
Since the SCSI controller circuit is embedded in the standard 3.5-inch hard disk drive form factor,
the HDD is extremely compact. The HDD can be connected directly to the SCSI bus of the host
system.
Environmental Protection
The HDDs comply with the Restriction of the use of certain Hazardous Substances in electrical
and electronic equipment (RoHS) directive issued by European Union (EU).
SCSI standard
The HDD provides not only SCSI basic functions but also the following features:
•
Arbitration
•
Disconnection/Reconnection
•
Data bus parity
The SCSI commands can manipulate data through logical block addressing regardless of the
physical characteristics of the HDD. This allows software to accommodate future expansion of
system functions.
8-bit SCSI/16-bit SCSI
The HDD has 16-bit data bus width (16-bit SCSI), which have the wide transfer function suitable
for SCSI-2. 8-bit data bus is available only with NP model.
See subsection 5.3.2 for details of the bus width setting.
For the ultra SCSI model, number of connectable SCSI devices on the same SCSI bus is varied as
follows.
•
8-bit SCSI: 8 drives max. (option for NP model)
•
16-bit SCSI: 16 drives max.
