Overview

Quantum Atlas 10K III SCSI hard disk drives are part of a family of high performance 1-inch high hard disk drives manufactured to meet the highest

product quality standards. The innovative design of the Quantum Atlas 10K III enables Quantum to produce a family of low-cost, high reliability

SCSI hard disk drives. These hard disk drives use non-removable, 3.5-inch hard disks and are available with the following SCSI configurations:

lUltra160, Ultra2, Ultra SCSI 68-pin Wide (16-bit).

lUltra160, Ultra2, Ultra SCSI 80-pin SCA-2 (16-bit).

The Quantum Atlas 10K III SCSI hard disk drives feature an embedded SCSI drive controller that automates significant SCSI commands to

optimize system performance. The drive also manages media defects and error recovery internally, making these operations fully transparent to

the user.

General Features

The Quantum Atlas 10K III 18GB SCSI hard disk drives include the following key features:

lFormatted storage capacity of 18.2GB.

lLow profile, 1-inch height.

lIndustry standard 3.5-inch form factor.

lEmbedded SCSI controller.

lSCSI-2 and SCSI-3 support.

lSCSI bus active negation drivers.

lSCSI bus fairness.

lAutomatic Power Management System with power saving sub-states.

lEmbedded servo system for exceptional head positioning accuracy and long life.

lQuiet Drive Technology (QDT) for lower acoustic noise while seeking.

Performance

lAverage seek time of less than 4.5ms for reads.

l10,000 RPM rotational speed.

lAverage rotational latency of 3.0ms.

l8MB SDRAM buffer. Look-ahead DisCache feature with continuous prefetch and WriteCache write-buffering capabilities.

lRead-on-arrival firmware.

lTagged command queuing with reordering (ORCA).

lECC on-the-fly data correction.

lHighly automated SCSI protocol (including AutoRead and AutoWrite).

l1:1 interleave on read and write operations.

lHigh performance Ultra160 SCSI interface.

lData transfer rates of up to 6.0MB/s asynchronous, 40MB/s Ultra SCSI, 80MB/s Ultra2 SCSI, and 160MB/s Ultra160 SCSI.

Reliability

l1,100,000 hours Mean Time Between Failure (MTBF).

l352-bit interleaved Reed-Solomon Error Correction Code (ECC), with cross checking correction of up to three separate bursts of 32 bits

each totalling up to 96 bits in length.

lSMART 2 (Self-Monitoring, Analysis and Reporting Technology).

lSelf-Diagnostic firmware.

lPatented Airlock automatic shipping lock and dedicated landing zone.

lTransparent media defect mapping.

lReassignment of defective sectors without reformatting.

lShock sensor prevents the drive from writing data to disk when the drive is subjected to excessive external shock.

NOTE: The formatted capacity of your hard disk drive may seem smaller than what you ordered because the operating system reports

drive capacity assuming that 1 megabyte (MB) equals 1,048,576 (220) bytes while drive manufacturers consider 1 MB to equal

1,000,000 (106) bytes.

lThermal sensor monitors the drive temperature to ensure on-going drive reliability.

lShock Protection System II (SPS II) protects the drive against specific types of handling events that could cause damage to the drive.

Versatility

lDownloadable firmware.

lPlug-and-Play SCSI.

The Quantum Atlas 10K III SCSI hard disk drive has one jumper connector provided for configuration in a system. The following feature is jumper

selectable:

lForce Single Ended

Figure 1. Jumper Location

Force Single Ended

Install a jumper across pin pair SE to operate the disk drive as a single ended device. Remove the jumper for LVD operation and

monitoring of the DIFFSENS signal.

No Connection

The Quantum Atlas 10K III SCSI hard disk drive is shipped with a spare jumper installed on pin pair NC. Functionality of the hard disk

drive is not affected by installing or removing this jumper.

Dell Installed Drives •Customer Kits

Dell Installed Drives

Dell performs the installation and setup on SCSI hard disk drives that are shipped as part of a system. The default SCSI ID for a boot hard disk

drive installed in a Dell system is SCSI ID 0. After installing the drive, Dell prepares the drive for operation with your operating system. The drive is

ready for use when you receive your system.

Customer Kits

Installation Guidelines

Consult the Dell documentation for your system to determine drive requirements, such as number, type, and physical size of drives

supported.

SCSI ID of the Drive

Default is SCSI ID 0.

Verify that there are no SCSI ID conflicts with other SCSI devices.

SCSI Interface

The SCSI interface is 80-pin SCA-2.

Termination

The Quantum Atlas 10K III SCSI hard disk drive cannot be configured to provide bus termination. Therefore, be sure to properly

terminate the SCSI bus on which this drive is installed.

Installing the Drive

The mounting holes on the Quantum Atlas 10K III SCSI hard disk drive allow the drive to be mounted in any orientation. For mounting,

#6-32 UNC screws are recommended.

Preparing the Drive for Operation

The Quantum Atlas 10K III SCSI hard disk drive is shipped from the manufacturer low-level formatted in 512-byte sectors. Use the

programs provided with the SCSI host adapter card to prepare the drive for operation.
