1.8.1 SCSI Performance
The LSI53C1020 contains the following SCSI performance features:
• Supports Ultra320 SCSI
– Paced transfers using a free-running clock
– 320 Mbytes/s SCSI data transfer rate
– Mandatory packetized protocol
– Quick arbitrate and select (QAS)
– Skew compensation with bus training
– Transmitter precompensation to overcome ISI effects for SCSI
data signals
– Retained training information (RTI)
• Offers a performance-optimized architecture
– Two ARM966E-S processors provide high performance with low
latency
– Designed for optimal packetized performance
• Uses proven integrated LVDlink transceivers for direct attach to either
LVD or SE SCSI buses with precision-controlled slew rates
• Supports expander communication protocol (ECP)
• Uses the Fusion-MPT (Message Passing Technology) drivers to
provide full operating system support for the Windows, Linux
,
Solaris,
SCO OpenServer, UnixWare, OpenUnix 8, and NetWare operating
systems
