2.3 Reference documents SCSI Commands Reference Manual Seagate part number: 100293068 Fibre Channel Interface Manual Seagate part number: 100293070 ANSI Fibre Channel Documents X3.230-1994 X3.297.1997 X3.303.1998 X3.272-1996 X3.
3.0 General description Savvio 10K.4 FC drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Savvio 10K.4 FC drives support 4-Gb Fibre Channel which can transfer data at up to 800MBs per second and 1600MBs per second in dual-loop configurations. Savvio 10K.
3.1 Standard features Savvio 10K.
3.3 Performance • Programmable multi-segmentable cache buffer • 800MB/s maximum instantaneous data transfers per port • 10K RPM spindle. Average latency = 3.0ms • 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 Savvio 10K.4 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 ST9600204FC 600 6 240,000 1,430 343 1.62 10K 3.0 ST9450404FC 450 6 180,000 1,430 257.4 1.62 10K 3.
4.2.2 Format command execution time (minutes) ST9600204FC ST9450404FC Maximum (with verify) 181 136 Maximum (without verify) 91 68 Note. There is approximately a 1.5 increase in time to format a SED drive versus a non-SED drive of the same capacity. 4.2.
4.5 Cache operation Note. Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits. Of the 16MBs physical buffer space in the drive, approximately 13,000KB can be used as a cache. The buffer is divided into logical segments from which data is read and to which data is written. The drive keeps track of the logical block addresses of the data stored in each segment of the buffer.
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. For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field contains the type of predictive failure that occurred. The error code is preserved through bus resets and power cycles. Determining rate S.M.A.R.T.
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.
6.0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 6.1 PowerChoiceTM power management Drives using the load/unload architecture provide programmable power management to tailor systems for performance and greater energy efficiency. The table below lists the supported PowerChoice modes. The further you go down in the table, the more power savings you get.
6.1.1 PowerChoice reporting methods PowerChoiceTM provides these reporting methods for tracking purposes: Request Sense command reports • Current power condition • Method of entry Note. Processing the Request Sense command does not impact the drive’s power save state.

6.5 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). Note. To maintain optimal performance drives should be run at nominal case temperatures. 6.5.1 Temperature a.

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%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated.

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 4 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 Savvio 10K.4 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 (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.
If forced air is necessary, possible air-flow patterns are shown in Figure 8. The air-flow patterns are created by fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow patterns are acceptable as long as the temperature measurement guidelines of Section 6.5.1 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 22.
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 24 for a mapping of SEL to FC-AL physical addresses (AL_PA). You can think of the SEL lines as the equivalent of a backpanel logic plug. The drives does not provide pull up resistors on these lines.

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 25: 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 27 for the output characteristics of the LED drive signals. Table 27: LED drive signal State Current drive available LED off, high 0 < IOH < 100µA LED on, low IOL < -30 mA 9.6.3 Output voltage 0 < VOL < 0.8V FC Differential output The serial output signal voltage characteristics are provided in Table 28.
