Page 11: Scope
Barracuda 18FC drives support the Fibre Channel Arbitrated Loop and SCSI Fibre Channel Protocol specifica- tions to the extent described in this manual. The Fibre Channel Interface Manual (part number 77767496) describes the general Fibre Channel Arbitrated Loop characteristics of this and other Seagate Fibre Channel drives. -

Page 15: General Description
You can view the Fibre Channel interface simply as a transport vehicle for the supported command set (ST118273FC drives use the SCSI command set). In fact, the Fibre Channel interface is unaware of the con- tent or meaning of the information being transported. It simply packs the SCSI commands in frames, transports them to the appropriate devices, and provides error checking to ensure that the information reaches its destina- tion accurately. -

Page 21: Cache Operation
Barracuda 18FC Product Manual, Rev. B Cache operation Note. Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits. Of the 1,024 Kbytes physical buffer space in the drive, 967.5 Kbytes can be used as a cache. The cache can be divided into logical segments from which data is read and to which data is written. - Page 22 Barracuda 18FC Product Manual, Rev. B For write caching, the same buffer space and segmentation is used as set up for read functions. When a write command is issued, the cache is first checked to see if any logical blocks that are to be written are already stored in the cache from a previous read or write command.

Barracuda 18FC Product Manual, Rev. B with a Medium (03h) or Hardware error (04h) reported in the Sense Key. This is an unrecoverable seek error. Unrecoverable seek errors are classified as failures for MTBF calculations. 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. -
Page 25: Reliability And Service
Barracuda 18FC Product Manual, Rev. B 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. -

Page 31: Environmental Limits
Non-operating temperature should remain between –40°F to 158°F (–40°C to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This assumes that the drive is packaged in the shipping con- tainer designed by Seagate. 6.4.2 Relative humidity The values below assume that no condensation on the drive occurs. -
Page 32: Air Cleanliness
Disc drives shipped as loose load (not palletized) general freight will be packaged to withstand drops from heights as defined in the table below. For additional details, refer to Seagate specifications 30190-001 (under 100 lbs/45 kg) or 30191-001 (over 100 lbs/45 kg). -
Page 33: Electromagnetic Susceptibility
Barracuda 18FC Product Manual, Rev. B Electromagnetic susceptibility As a component part, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of the system integrator to perform tests required to ensure that equipment operating in the same system as the drive does not adversely affect the performance of the drive. -
Page 35: Defect And Error Management
Barracuda 18FC Product Manual, Rev. B 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). -

Barracuda 18FC Product Manual, Rev. B When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. -
Page 37: Installation
Barracuda 18FC Product Manual, Rev. B Installation Barracuda 18FC disc 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. -

Page 39: Figure 7. Air Flow
Barracuda 18FC Product Manual, Rev. B The drive should be oriented, or air flow directed, so that the least amount of air-flow resistance is created while providing air flow to the electronics and HDA. Also, the shortest possible path between the air inlet and exit should be chosen to minimize the travel length of air heated by the drive and other heat sources within the rack, cabinet, or drawer environment. -
