1.3.2 Cyclic Redundancy Check (CRC)

Ultra160 SCSI includes CRC which offers higher levels of data reliability by ensuring complete integrity of transferred data. CRC is a 32-bit scheme, referred to as CRC-32. CRC is guaranteed to detect all single bit errors, any two bits in error, or any combination of errors within a single 32-bit range.

1.3.3 Asynchronous Information Protection (AIP)

The LSI53C1000 also supports AIP, which protects all nondata phases, including command, status, and messages. CRC, along with AIP, provides end-to-end protection of the SCSI I/O.

1.4 SureLINK™ Ultra160 SCSI Domain Validation Beneﬁts

SureLINK software represents the very latest SCSI interconnect management solution. It ensures robust and low risk Ultra160 SCSI implementations by extending the Domain Validation guidelines documented in the ANSI T10 SPI-3 speciﬁcations. Domain Validation veriﬁes that the system is capable of transferring data at Ultra160 speeds, allowing it to renegotiate to lower speed and bus width if necessary.

SureLINK software is the control for the manageability enhancements in the LSI53C1000. Fully integrated in the SDMS software solution, SureLINK software provides Domain Validation at boot time, as well as throughout system operation.

1.5 LVDlink™ Technology Beneﬁts

The LSI20160 supports LVD for SCSI, a signaling technology that increases the reliability of SCSI data transfers over longer distances than are supported by SE SCSI. The low current output of LVD allows the I/O transceivers to be integrated directly onto the chip. LVDlink technology lowers the amplitude of noise reﬂections and allows higher transmission frequencies. LVD provides a long-term migration path to even faster SCSI transfer rates without compromising signal integrity, cable length, or connectivity.
