NL35 Series drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual (part number 77767496) which describes the general interface characteristics of this drive.
Standard features NL35 Series drives have the following standard features: • Integrated dual port FC-AL controller • Concurrent dual port transfers • Support for FC arbitrated loop, private and public attachment • Differential copper FC drivers and receivers • Downloadable firmware using the FC-AL interface •...
938165665 37EB45A1 2. Seagate drives also may be used at the maximum available capacity at a given sector size, but the excess capacity above the guaranteed level will vary between 7K, 10K and 15K families and from generation to generation, depending on how each sector size actually formats out for zone frequencies and splits over servo bursts.
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.

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.
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.
To determine the warranty for a specific drive, use a web browser to access the following web page: www.seagate.com/support/service/ From this page, click on the “Verify Your Warranty” link. You will be asked to provide the drive serial number, model number (or part num- ber) and country of purchase.
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 recov- ered 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.
5.2.1 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.
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.
DST. It is the responsibility of the host application to determine the “not ready” cause. While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive.
Page 31
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.
Seagate’s option and at no charge to the customer, if returned by customer at cus- tomer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer.
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 Voltage Regulation Avg idle current DC Maximum starting current (peak DC) DC 3σ...
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 cur- rent by <0.5%.
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).
Non-operating –40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with drive. HDA Temperature Check Point Figure 4.
>600 cu in (>9,800 cu cm) Drives packaged in single or multipacks with a gross weight of 20 pounds (8.95 kg) or less by Seagate for general freight shipment shall withstand a drop test from 48 inches (1,070 mm) against a concrete floor or equivalent.
6.4.4.2 Vibration a. Operating - normal The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous vibration not exceeding 5-22 Hz @ 0.25 G (zero to peak) 22-350 Hz @ 0.50 G (zero to peak) 350-500 Hz @ 0.25 G (zero to peak) Vibration may be applied in the X, Y, or Z axis.
The sil- ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%.
Mechanical specifications The following nominal dimensions are exclusive of the decorative front panel accessory. However, dimensions of the front panel are shown in figure below. Refer to Figure 6 for detailed mounting configuration dimensions. See Section 8.4, “Drive mounting.” Height: 1.010 +/- 0.14 in.
Defect and error management The drive, as delivered, complies with this product manual. The read error rates and specified storage capaci- ties 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 recov- ery time limit for the command has not yet been met.
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.
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) 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.
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 Sec- tion 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.
(F) is applied to the fourth point. Note. Before mounting the drive in any kind of 3.5-inch to 5.25-inch adapter frame, verify with Seagate Technology that the drive can meet the shock and vibration specifications given herein while mounted in such an adapter frame.
