change the capacity it is currently formatted to have. A number in the number of blocks field that is less than the maximum number of LBAs changes the total drive capacity to the value in the block descriptor number of blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity. 3.6 Factory-installed accessories OEM standard drives are shipped with the Cheetah 10K.7 36GB FC Installation Guide (part number 100384023). 3.
4.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Cheetah 10K.7 FC 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 ST336807FC 36.8..................... ................................Gbytes (formatted, rounded off value) 1 556.

Rate measured from the start of the first logical block transfer to or from the host. Notes for Section 4.2.
The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit in the Fibre Channel Interface Manual), data requested by the host with a read command is retrieved from the buffer, if possible, before any disc access is initiated.
If the number of write data logical blocks exceed the size of the segment being written into, when the end of the segment is reached, the data is written into the beginning of the same cache segment, overwriting the data that was written there at the beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium.

5.1.2 Unrecoverable errors Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 1015 bits transferred. Unrecoverable Data Errors resulting from the same cause are treated are 1 error for that block. 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.
5.2.3 Hot plugging the drive Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the receiver of the next device in the loop must synchronize to a different input signal. FC error detection mechanisms, character sync, running disparity, word sync, and CRC are able to detect any error. Recovery is initiated based on the type of error.
Performance impact S.M.A.R.T. attribute data is saved to the disc so that the events that caused a predictive failure can be recreated. The drive measures and saves parameters once every two hours subject to an idle period on the FC-AL bus. The process of measuring off-line attribute data and saving data to the disc is uninterruptable. The maximum on-line only processing delay is summarized below: Maximum processing delay S.M.A.R.T.
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in compliance with the SCSI standard. The drive temperature is reported in the FRU code field of mode sense data. You can use this information to determine if the warning is due to the temperature exceeding the drive threatening temperature or the user-specified temperature.
5.2.6.1 DST Failure Definition The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional failure is encountered during DST. The channel and servo parameters are not modified to test the drive more stringently, and the number of retries are not reduced. All retries and recovery processes are enabled during the test.
Short test (Function Code: 001b) The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A complete read/verify scan is not performed and only factual failures will report a fault condition. This option provides a quick confidence test of the drive.
Shipping When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty. Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact your authorized Seagate distributor to purchase additional boxes.
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: ST336807FC DC power requirements ST336807FC 1 Gbit Notes (Amps) (Amps) (Amps) (Amps) +5V +12V [2] +5V +12V [2] [5] ±5% ±5% [2] ±5% ±5% [2] [1] [7] 0.86 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 254 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%.
6.2.3 Current profiles Figures 2 and 3 identify the drive current profiles. The current during the various times is as shown: Note: All times and currents are typical. See Table 11 for maximum current requiremST336807FC Figure 2. Typical ST336807FC drive, 2 Gbit, +12V current profile Figure 3. Typical ST336807FC drive, 2 Gbit, +5V current profile Cheetah 10K.7 36GB FC Product Manual, Rev.
6.3 Power dissipation ST336807FC Typical power dissipation under idle conditions is 8.38 watts (28.60 BTUs per hour) during 1 Gbit operation. Typical power dissipation under idle conditions is 8.68 watts (29.62 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 4).
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 AFR 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.
