Functional Architecture
✏ ^NOTE
In PIC mode, the 6300ESB I/O can connect each PIRQ line internally to one of the IRQ signals
(3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a PIRQ line will
have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for
two or more of the PIRQ lines to be connected to the same IRQ signal. See Table 7 for the
allocation of PIRQ lines to IRQ signals in APIC mode.
3.4.5
SCSI Support
The SCSI sub-system consists of the Adaptec 7901 Single Channel, PC-2001-compliant PCI-X
Ultra 320 SCSI controller which has one internal 80-pin connector (SCSI Channel A).
3.4.5.1
Adaptec 7901 Single Channel Ultra 320 SCSI Controller
The Adaptec 7901 is PCI bus master single-channel SCSI ASICs package. The Adaptec 7901
is an Ultra320 SCSI ASIC supporting a data transfer rate up to 320 MB/sec. The Adaptec 7901
complies with PCI Local Bus Specification, Revision 2.2 PCI-X Addendum, Rev. 1.0, and SCSI
Parallel Interface-4 (SPI-4) for both Single-Ended (SE) and Low Voltage Differential (LVD)
devices.
These ASICs comply with:
PCI Local Bus Specification, Revision 2.2
PCI-X Addendum, Revision. 1.0a
SCSI Parallel Interface-4 (SPI-4), Revision 6
For both Single-Ended (SE) and LVD devices. In addition, they comply with the SCSI-3
standard and provide multimode SCSI support.
In PCI and PCI-X modes, these ASICs can operate as a multifunction 32-bit or 64-bit bus
master capable of supporting zero-wait-state 32- or 64-bit memory transfers. They can also
function as a PCI or PCI-X target.
The Adaptec 7901 supports up to 64-bit, 122 MHz PCI-X bus. The Ultra320 SCSI features for
the Adaptec 7901 include:
z Double-transition (DT) clocking
z Paced transfers using packetized protocol
z Packetized protocol
z Dual data FIFO
z Quick arbitration and selection/reselection (QAS) protocol
z Manual PIO mode data transfer
z Automatic mode data transfer
z Normal (DMA) mode data transfer
z Cyclic redundancy check (CRC) codes
The single-channel Adaptec 7901 delivers Ultra320 SCSI data rates up to 320 MBytes/sec to
address emerging bandwidth hungry applications, such as real-time video, data mining,
Internet/Intranet, and scientific modeling and simulation. The chip features a 66 MHz, 64-bit PCI
interface and a 133 MHz, 64-bit PCI-X interface.
