Page 11: General Description
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 sup- port 4-Gb Fibre Channel which can transfer data at up to 800MBs per second and 1600MBs per second in dual-loop configurations. -
Page 12: Standard Features

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 10K and 15K families and from generation to gener- ation, depending on how each sector size actually formats out for zone frequencies and splits over servo bursts. -
Page 14: Programmable Drive Capacity
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. -

Page 17: Cache Operation
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. -
Page 18: Caching Write Data
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 avail- able for future read cache hits. -
Page 19: Reliability Specifications
Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate: Read Error Rates Recovered Data Unrecovered Data Miscorrected Data Interface error rate: Mean Time Between Failures (MTBF) Annualized Failure Rate (AFR): Preventive maintenance:... -
Page 20: Seek Errors
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. -

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. -

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 24 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.

Page 41: Defect And Error Management
SCSI defect and error management involves drive internal defect/error management and FC system error con- siderations (errors in communications between the initiator and the drive). In addition, Seagate provides the following technologies used to increase data integrity and drive reliability: •... - Page 42 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 re- read or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts.
-
Page 43: Fc-Al System Errors
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. -
Page 44: Deferred Auto-Reallocation
DAR is most effective when AWRE and ARRE are enabled—this is the default setting from the Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will report an error sense code indicating that a write command is being attempted to a previously failing location. -
Page 45: Installation
Installation Savvio 10K.4 FC disk drive installation is a plug-and-play process. There are no jumpers, switches, or termina- tors 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. -
Page 46: Drive Mounting
(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. -
Page 47: Grounding
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 electri- cally 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 mount- ing the drive in the host equipment. -
