The LSI20860, 32-bit PCI, single-channel Ultra (Narrow) SCSI HBA is ideal for attaching Ultra SCSI tape drives, CD-Rom drives, removable storage, scanners and other SCSI peripherals to PCs, workstations and servers. The LSI20860 can be used to control up to seven devices supporting the SCSI-1, SCSI-2, Fast SCSI-2, and SCSI-3 protocols or devices using single-ended (SE) signaling. With data transfer rates as high as 20 MB/s, the LSI20860 unlocks the performance potential of SCSI peripherals.
LSI20860 KIT - PCI-Fast, Ultra, 8-bit HBA Order #: LSI00029
The LSI20860 joins PCI, the fastest standard systems bus available
today, with the high performance of Ultra SCSI I/O technology. Based on
the industryas first PCI-SCSI RISC processor, the LSI20860 realizes the full
throughput potential of SCSI I/O with 32-bit, bus-mastering (DMA) PCI transfer
rates. This robust adapter transfers data at the highest rate of each SCSI
device on the bus without downgrading the bus to the slowest device.
Combining low cost and high performance, the LSI20860 is an excellent solution for OEM peripheral attach and desktop applications.
This document provides complete functional descriptions, electrical specifications, and physical characteristics for the LSI53C860 PCI to Ultra SCSI I/O processor. The LSI53C860 enables the connection of Ultra SCSI drives to a host system through a PCI bus. Ultra SCSI is an extension of the SCSI-3 specification that supports transfers of up to 20 Mbytes/s.
The LSI53C860 integrates a high-performance Ultra SCSI core, a PCI bus master DMA core, and the SCSI SCRIPTs processor. The SCRIPTs processor reduces protocol overhead.
This user's guide provides detailed installation and usage information for the LSI20860 PCI to Ultra SCSI host adapter. The user's guide includes a description of host adapter features, installation instructions, and physical and operational specifications. The LSI20860 host adapter has one independent Ultra SCSI channels and supports Fast and Ultra SCSI devices.
