Average latency = 2.98 msec • Command queuing of up to 128 commands • Background processing of queue • Supports start and stop commands (spindle stops spinning) • Adaptive seek velocity; improved seek performance 3.4 Reliability • Annualized Failure Rate (AFR) of 0.
3.6 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 SCSI Commands Reference 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 Cheetah NS 10K.2 FC drives. 4.1 Internal drive characteristics Drive capacity* Read/write data heads Tracks per inch Peak bits per inch Areal density Internal data rate disk rotation speed Avg rotational latency ST3600002FC 600 8 165,000 1,347 225 1.01 to 1.84 10k 2.98 ST3450802FC 450 6 165,000 1,347 225 1.01 to 1.84 10k 2.98 ST3300602FC 300 4 165,000 1,347 225 1.

When changing sector sizes, the format times shown above may need to be increased by 30 minutes. 4.2.
4.4 Prefetch/multi-segmented cache control The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h.
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 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.
5.0 Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate: Read Error Rates1 Recovered Data Unrecovered Data Miscorrected Data Interface error rate: Mean Time Between Failures (MTBF) Annualized Failure Rate (AFR): Preventive maintenance: 1.
5.1.3 Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in 108 seeks.
The Pass-through state is disabled while the drive performs self test of the FC interface. The control line for an external port bypass circuit remains in the Enable Bypass state while self test is running. If the bypass circuit is present, loop operation may continue. If the bypass circuit is not present, loop operation will be halted while the self test of the FC interface runs.
Reporting control Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method, the firmware will issue to the host an 01-5Dxx sense code. The error code is preserved through bus resets and power cycles. Determining rate S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to an unacceptable level.
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 1: Temperature Log Page (0Dh) Parameter Code Description 0000h Primary Temperature 0001h Reference Temperature 5.2.
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 disk In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code. 5.2.6.2.
The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC, ASCQ, and FRU are used to report the failure condition. 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.

7.0 Defect and error management Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to increase data integrity, perform drive self-maintenance, and validate proper drive operation. SCSI defect and error management involves drive internal defect/error management and FC system error considerations (errors in communications between the initiator and the drive).
The drive firmware error recovery algorithms consists of 11 levels for read recoveries and five levels for write. Each level may consist of multiple steps, where a step is defined as a recovery function involving a single reread or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts. Table 5 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual LBAs.
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.
7.6 Deferred Auto-Reallocation Deferred Auto-Reallocation (DAR) simplifies reallocation algorithms at the system level by allowing the drive to reallocate unreadable locations on a subsequent write command. Sites are marked for DAR during read operations performed by the drive. When a write command is received for an LBA marked for DAR, the auto-reallocation process is invoked and attempts to rewrite the data to the original location.
8.0 Installation Cheetah NS 10K.2 FC disk 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 (FCSCA)—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.
If forced air is necessary, possible air-flow patterns are shown in Figure 10. 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.
8.5 Grounding Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in which the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock mounts. If it is desired for the system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user must provide a nonconductive (electrically isolating) method of mounting the drive in the host equipment.

9.5.6 Power Power is supplied through the FC-SCA with support for +5 volts and +12 volts. All of the voltage pins in the drive connector are the same length. Four 12 volt pins provide +12 volt power to the drive. The current return for the +12 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current typically occurs while the drive motor is starting.
9.5.8 Active LED Out The Active LED Out signal is driven by the drive as indicated in Table 24.
Table 25: Motor start control signals Case Start_2 Start_1 Motor spin function 4 High High The drive will not spin up. 9.5.11 SEL_6 through SEL_0 ID lines The SEL_6 through SEL_0 ID lines determine drive address, and, optionally, for an Enclosure Services Interface. When the Parallel ESI line is high, the enclosure backpanel must provide address information on the SEL line. Refer to table 26 for a mapping of SEL to FC-AL physical addresses (AL_PA).

9.5.12 Device control codes The drive inputs a Device Control Code on the DEV_CTRL_CODE lines at power up to determine the link rate on the Fibre Channel ports. Both ports run at the same rate. If the backpanel does not connect to these lines, the drive has 10K ohm pull up resistors that default the device control code to 7 (1.0625 GHz). Table lists the supported codes. Table 27: Device control code values 2 (pin 17) 1 (pin 18) 0 (pin 39) Definition 0 0 0 Reserved for power failure warning.
9.6.2 LED driver signals Fault and Active LED signals are located in the FC-SCA connector (J1). See Table 29 for the output characteristics of the LED drive signals.
