Performance
• 64-bit, 66 MHz PCI interface supports zero wait-state memory –
also operates on PCI busses down to 32-bit, 33 MHz
• Up to 160 MByte/sec on the Ultra160 SCSI bus
• 20-MIPS PhaseEngine^® RISC processor for fast SCSI command processing
• 1024-byte data FIFO buffer for efficient PCI bus utilization
• Cache line-streaming for improved PCI bus utilization
• Dual Address Cycle (DAC) provides greater system memory addressibility
• Target mode to support clustering, bridge, and RAID applications
• Tagged command queuing enables changing SCSI command execution order
to improve performance
Additional Features
• Advanced multimode Ultra160 SCSI I/O cell for supporting Low Voltage
Differential (LVD) or single-ended devices
• Ultra160 and Ultra3 SCSI Domain Validation and CRC support
• JTAG boundary scan to support system-level interconnect testing
• 3.3V/5V PCI interface for providing flexibility in designing high-performance,
low-power systems
• Enhanced Logical Unit Number (LUN) supports up to a maximum of 32 LUNs
• Microsoft PC99 compatible
• PCI Hot-Plug compatible
• Fully compatible with the AIC-3860 SCSI transceiver chip
Software Support
• Microsoft^® Windows NT^®, Windows^® 95 and 98, Novell NetWare, SCO Openserver,
SCO UnixWare, IBM OS/2, Sun Solaris, and Linux
SCSI Device Support
