Wide Ultra3 SCSI Support
The 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter provides
64-Bit PCI bus master operation and SCSI data transfer rates of up to 160
MB/s, provided that all components are Wide Ultra3 capable. This
combination allows high throughput in many network application
environments, including resource-sharing, database-servicing, and
high-performance backup solutions.
The adapter also supports tagged command queuing, which allows SCSI hard
drives to queue and sort multiple commands, then execute those commands
simultaneously.
The 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter complies with
ANSI SCSI-3 standards, supporting Wide Ultra3 SCSI, Wide Ultra2 SCSI,
Wide-Ultra SCSI-3, Fast-Wide SCSI-2, and Fast-SCSI-2 devices. The
64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter can support several
different SCSI devices at one time.
PCI
The 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter interface to the
server processor is the PCI local bus. The PCI bus is a high-performance,
64-bit bus with multiplexed address and data lines. The PCI bus provides a
high-speed (up to 528 MB/s) path between the system unit and peripherals.
Peripheral devices, such as Wide Ultra3 SCSI adapters, benefit the most from
the high I/O performance of the PCI bus.
The 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter is
backward- compatible in a 32-bit/33 MHz or 64-bit/33 MHz PCI slot.
The 64-Bit/66 MHz Single Channel Wide Ultra3 SCSI Adapter is a PCI bus
master device and conforms to Rev. 2.1 and 2.2 of the PCI Local Bus
Specification.
