SCSI subsystem
The dual-channel AIC-7899 single-chip host adapter delivers Ultra
160/m SCSI data transfer rates which double the Ultra-2 SCSI data
transfer rate of up to 160 MByte/s. With two channels, it delivers a
total of 320 MByte/s bandwidth. In addition, the AIC-7899 features a
66 MHz, 64-bit PCI interface that supports zero wait-state memory
which also operates on 33 MHz, 32-bit PCI buses. It supports up to 15
devices on a 12-meter cable (or 25 meters in a point-to-point
configuration), making it ideal for both clustering and RAID
configurations.
LAN subsystem
Another cost-effective feature for network solution is the integration
of four Intel
82550 10/100 Mbps Fast Ethernet controllers. With its
sophisticated 32-bit PCI component and enhanced scatter-gather bus
mastering capabilities, it enables high-level command processing and
multiple operations which lowers CPU utilization. It also offers several
new features including:
• IPSec integration
• Host side cardbus interface
• Enhanced power management
• Optimized support for flash devices and modem combination
interface
• Auto-Negotiation capability
Video subsystem
