3.0 General description NL35 Series drives combine Tunneling Magnetoresistive (TMR) heads and a Fibre Channel interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.
3.
3.2 Media description The media used on the drive has an aluminum substrate coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability and environmental protection. 3.3 Performance • Programmable multi-segmentable cache buffer • 200 Mbytes/sec maximum instantaneous data transfers per port • 7K RPM spindle; average latency = 4.17 msec • Command queuing of up to 64 commands • Background processing of queue • Supports start and stop commands 3.
3.5.1 Programmable drive capacity Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select Parameter List table in the FC Interface Product Manual. Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall not change the capacity it is currently formatted to have.
4.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of NL35 Series drives. 4.1 Internal drive characteristics Drive capacity* Read/write data heads Bytes per track Bytes per surface Tracks per surface (total) Tracks per inch Peak bits per inch Internal data rate Disc rotation speed Avg rotational latency ST3500071FC ST3400071FC 500.0 ........................ 400.0........................ ..................
4.2.
4.3 Start/stop time If the Motor Start option is disabled, the drive becomes ready within 25 seconds after DC power is applied. If a recoverable error condition is detected during the start sequence, the drive executes a recovery procedure and the time to become ready may exceed 25 seconds. Stop time is less than 30 seconds (maximum) from removal of DC power.
Case B—A Read command requests data, and the first logical block is not in any segment of the cache: 1. The drive fetches the requested logical blocks from the disc and transfers them into a segment, and then from there to the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h. 2. If the prefetch feature is enabled, refer to section 4.5.2 for operation from this point.
To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead—DRA bit). DRA bit = 0 enables prefetch. Since data that is prefetched replaces data already in some buffer segments, the host can limit the amount of prefetch data to optimize system performance. The Max Prefetch field (bytes 8 and 9) limits the amount of prefetch. The drive does not use the Prefetch Ceiling field (bytes 10 and 11).

5.1.1 Recoverable Errors Recovereable errors are those detected and corrected by the drive, and do not require user intervention. Recoverable Data errors will use correction, although ECC on-the-fly is not considered for purposes of recovered error specifications. Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a read, and using write bits transferred for recoverable errors occurring during a write. 5.1.
5.2.1 Mean Time Between Failure (MTBF) The production disc drive shall achieve an MTBF of 1,000,000 hours when operated in an environment that ensures the HDA case temperatures specified in Section 6.4 are not exceeded. Short-term excursions up to the specification limits of the operating environment will not affect MTBF performance. Continual or sustained operation at case temperatures above the values shown in Section 6.4.1 may degrade product reliability.
5.2.4 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow you to back up the data before an actual failure occurs. Note. The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive failures.
Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set thresholds for the number of errors and their interval. If the number of errors exceeds the threshold before the interval expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is considered to be acceptable.
5.2.6 Drive Self Test (DST) Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level. There are two test coverage options implemented in DST: 1. Extended test 2. Short text The most thorough option is the extended test that performs various tests on the drive and scans every logical block address (LBA) of the drive.
5.2.6.2.2 Invoking DST To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short test or 010b for the extended test) in bytes 1, bits 5, 6, and 7. Refer to the Fibre Channel Interface Product Manual, part number 77767496, for additional information about invoking DST. 5.2.6.2.3 Short and extended tests DST has two testing options: 1. short 2. extended These testing options are described in the following two subsections.
5.2.6.2.5 Abort There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message to abort the diagnostic. You can abort a DST executing in background mode by using the abort code in the DST Function Code field. This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition). 5.2.
6.0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 6.1 AC power requirements None. 6.2 DC power requirements The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector. Table 11: ST3500071FC/ST3400071FC DC power requirements 1 Gbit Notes (Amps) (Amps) (Amps) (Amps) +5V +12V [2] +5V +12V [2] [5] ±5% ±5% [2] ±5% ±5% [2] [1] [7] 0.94 0.
[5] [6] [7] See paragraph 6.2.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and transient response. Operating condition is defined as random 8 block reads at 161 I/Os per second. Current and power specified at nominal voltages. Decreasing +5 volt supply by 5% increases 5 volt current by <0.5%. Decreasing +12 volt supply by 5% increases 12 volt current by 1.4%.
6.3 Power dissipation Typical power dissipation under idle conditions is 10.49 watts (35.79 BTUs per hour) during 1 Gbit operation. Typical power dissipation under idle conditions is 10.75 watts (36.68 BTUs per hour) during 2 Gbit operation. To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 2).
6.4 Environmental limits Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb temperature is 82°F (28°C). 6.4.1 Temperature a. Operating The maximum allowable continuous or sustained HDA case temperature for the rated MTBF is 122°F (50°C) The maximum allowable HDA case temperature is 60°C.
6.4.4 Shock and vibration Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement.

7.0 Defect and error management The drive, as delivered, complies with this product manual. The read error rates and specified storage capacities are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI protocol involves the drive internal defect/error management and FC-AL system error considerations (errors in communications between the initiator and the drive).
Table 12 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recovery time limit for the command has not yet been met. Time needed to perform reallocation is not counted against the recovery time limit.
7.3 FC-AL system errors Information on the reporting of operational errors or faults across the interface is given in the Fibre Channel Interface Manual. The FCP Response returns information to the host about numerous kinds of errors or faults. The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive. Status returned by the drive to the initiator is described in the Fibre Channel Interface Manual.
38 NL35 Series FC Product Manual, Rev.
8.0 Installation NL35 Series disc drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC-SCA)—no cables are required. See Section 9.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
8.3 Cooling The host enclosure must provide heat removal from the drive. You should confirm that the host enclosure is designed to ensure that the drive operates within the temperature measurement guidelines described in Section 6.4.1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 6.4.1. If forced air is necessary, possible air-flow patterns are shown in Figure 7.
8.4 Drive mounting Mount the drive using the bottom or side mounting holes. If you mount the drive using the bottom holes, ensure that you do not physically distort the drive by attempting to mount it on a stiff, non-flat surface. The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm).
