Chapter 2
GENERAL DESCRIPTION
This chapter summarizes the general functions and key features of the Quantum
10K II Ultra 160/m SCSI family of hard disk drives, and lists applicable standards
and regulations.
2.1
PRODUCT OVERVIEW
Quantum Atlas 10K II Ultra 160/m SCSI hard disk drives are part of a family of
high performance, 1-inch high (low profile) and 1.6-inch high (half-height) hard
disk drives manufactured to meet the highest product quality standards. The disk
drives are designed for high-end PC-based workstations, RAID storage systems,
digital video applications, database servers, file servers, and other storage systems
where high capacity, extraordinary performance, and reliability are critical. These
hard disk drives use nonremovable 3.5-inch hard disks and are available with the
following SCSI configurations:
•
Ultra 160/m, Ultra2, Ultra SCSI 68-pin Wide (16-bit)
•
Ultra 160/m, Ultra2, Ultra SCSI 80-pin SCA-2 (16-bit)
There are currently four models in the Atlas 10K II series with capacities of 9.2,
18.4, 36.7, and 73.4 gigabytes (GB).
2.2
KEY FEATURES
Atlas 10K II Ultra 160/m SCSI disk drives include the following features
:
•
Formatted storage capacity of 9.2 GB (2 disks, 3 heads), 18.4 GB (3 disks, 5
heads), 36.7 GB (5 disks, 10 heads), and 73.4 GB (10 disks, 20 heads). The 9.2,
18.4, and 36.7 GB drives are in the 1.0-inch, low profile form factor; the 73.4
GB drive is in the 1.6-inch, half-height form factor.
•
MR heads and banded recording for higher overall bit-densities
•
Hardware XOR to automatically detect and correct errors and defects in the data
stream for array applications (RAID)
•
Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) Revision 2
support
•
ORCA (Optimized Reordering Command Algorithm) and tagged command
queuing for greater throughput
•
8 MB Track-oriented segmented cache buffer with prefetch
•
Automatic Power Management System with power-saving sub-states
•
10,000 rpm rotational speed yielding 3.0 ms average latency
