3.0 General description Savvio SCSI drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a wide Ultra320 SCSI interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Ultra320 SCSI uses negotiated transfer rates.
Savvio SCSI drives decode track 0 location data from the servo data embedded on each surface to eliminate mechanical transducer adjustments and related reliability concerns. A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides excellent performance with minimal power dissipation. 3.
3.4 Reliability • Mean time Between Failure (MTBF) of 1,400,000 hours • LSI circuitry • Balanced low mass rotary voice coil actuator • Incorporates industry-standard Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) • 5-year warranty 3.5 Formatted capacities Standard OEM models are formatted to 512 bytes per block. The sector size is selectable at format time.
3.7 Options (factory installed) All customer requested options are incorporated during production or packaged at the manufacturing facility before shipping. Some of the options available are (not an exhaustive list of possible options): • Other capacities can be ordered depending on sparing scheme and sector size requested. • Single unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit damage.

4.4 Prefetch/multi-segmented cache control The drive provides prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. “Cache” as used herein refers to the drive buffer storage space when it is used in cache operations. To select prefetch and cache features the host sends the Mode Select command with the proper values in the applicable bytes in Mode Page 08h (see the SCSI Command Reference Manual).
4.5.1 Caching write data Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to the medium is stored in one or more segments while the drive performs the write command. If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made available for future read cache hits. The same buffer space and segmentation is used as set up for read functions.
want to configure the cache to provide large volumes of sequential data in a non-repetitive manner. In this case, the ability of the cache to “look ahead” to the next contiguous segments of sequential data is a good thing. The Performance Mode (PM) bit controls the way the drive switches the cache buffer into different modes of segmentation.

5.0 Reliability specifications The following reliability specifications assume correct host/drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints (see Section 8.3).
5.1.2 Read errors Before determination or measurement of read error rates: • The data that is to be used for measurement of read error rates must be verified as being written correctly on the media. • All media defect induced errors must be excluded from error rate calculations. 5.1.3 Write errors Write errors can occur as a result of media defects, environmental interference, or equipment malfunction. Therefore, write errors are not predictable as a function of the number of bits passed.
A S.M.A.R.T. predictive failure indicates that the drive is deteriorating to an imminent failure and is considered an MTBF hit. 5.2.2 Preventive maintenance No routine scheduled preventive maintenance shall be required. 5.2.3 Service life The drive shall have a useful service life of five years. Depot repair or replacement of major parts is permitted during the lifetime (see Section 5.2.4). 5.2.4 Service philosophy Special equipment is required to repair the drive HDA.
End users should not mix devices with high voltage differential (HVD) drivers and receivers and devices with SE, LVD, or multimode drivers and receivers on the same SCSI bus since the common mode voltages in the HVD environment may not be controlled to safe levels for SE and LVD devices (see ANSI SPI-3). The disc drive spindle must come to a complete stop prior to completely removing the drive from the cabinet chassis.
Determining rate S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded error rate increases to an unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given attribute. The interval defines the number of operations over which to measure the rate. The counter that keeps track of the current number of operations is referred to as the Interval Counter. S.M.A.R.T.
can be used to set this trip point. The default value for this drive is 68°C, however, you can set it to any value in the range of 0 to 68°C. If you specify a temperature greater than 68°C in this field, the temperature is rounded down to 68°C. A sense code is sent to the host to indicate the rounding of the parameter field. Table 11: Temperature Log page (0Dh) Parameter Code Description 0000h Primary Temperature 0001h Reference Temperature When the first temperature trip point is exceeded, S.M.A.R.
While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive. A Drive Not Ready condition is reported by the drive under the following conditions: • Motor will not spin • Motor will not lock to speed • Servo will not lock on track • Drive cannot read configuration tables from the disc In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code. 5.2.9.2.
After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its SelfTest Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the last 20 self-tests performed by the drive. The self-test results value is a 4-bit field that reports the results of the test. If the field is zero, the drive passed with no errors detected by the DST. If the field is not zero, the test failed for the reason reported in the field.

7.0 Defect and error management The drive, as delivered, complies with this specification. The read error rate and specified storage capacity are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI system involves the drive internal defect/error management and SCSI systems error considerations (errors in communications between Initiator and the drive).
used when data integrity is not a concern and speed is of utmost importance. If the Recovery Time Limit or retry count is reached during error recovery, the state of the RC bit is examined. If the RC bit is set, the drive will transfer the unrecovered data with no error indication and continue to execute the remaining command. If the RC bit is not set, the drive will stop data transfer with the last good LBA, and report a “Check Condition, Unrecovered Read Error.
8.0 Note. Installation These drives are designed to be used only on single-ended (SE) or low voltage differential (LVD) busses. Do not install these drives on a high voltage differential (HVD) bus. The first thing to do when installing a drive is to set the drive SCSI ID and set up certain operating options. This is done via the drive to host I/O signals. Configure drive options Drive default mode parameters are not normally needed for installation. Refer to Section 9.3.
If forced air is necessary, possible air-flow patterns are shown in Figure 13. The air-flow patterns are created by fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced airflow patterns are acceptable as long as the temperature measurement guidelines of Section 6.4.1 are met. Above unit Note. Air flows in the direction shown (back to front) or in reverse direction (front to back) Under unit Above unit Note.
9.0 Interface requirements This section describes the drive-specific interface requirements as implemented on the drive. 9.1 General description This section describes in essentially general terms the interface requirements supported by the Savvio SCSI.
