When Fast SCSI devices are connected, the total length of all cables (internal
and external) must not exceed 3 meters (9.8 ft) to ensure reliable operation. If
no Fast SCSI devices are connected, the total length of all cables must not
exceed 6 meters (19.7 ft).
AIC-7895 consolidates the functions of two SCSI chips, eliminating the need for
a PCI bridge. Reducing PCI bus loading enables system capabilities to be
expanded with additional PCI devices.
The AIC-7895 functions with Adaptec RAIDport II (ARO-1130xA) to deliver RAID
functionality.
1-10 AIC -7890 Ultra II SCSI
Note: If you are using a low voltage differential Hard Drive, it is recommended you use LVD/
SE Ultra II SCSI cable. LVD/SE cable offers increased length, and can accommodate more
d e v i c e s .
SUPER P6DBU/P6SBU has an on-board SCSI controller which is 100% compat-
ible with all major operating and hardware platforms. The AIC-7890 controller
provides advanced PCI-to-SCSI Ultra2 SCSI host adapter features in a 272-pin
Ball Grid Array (BGA) package, as well as containing an integrated dual mode
(LVD/SE) transceiver. The AIC-7890 Ultra2 SCSI chip connects to a 32-bit PCI
bus. It is PCI 2.1 compliant, and fully supports the power management require-
ments specified in Microsoft's PC 97 guidelines and it provides SCAM level 2
support. The AIC-7890 functions with Adaptec RAIDport III (ARO-1130xA-2)
to deliver RAID functionality.
The AIC-7890 Ultra2 SCSI controller, used together with the AIC-3860 trans-
ceiver, allows Ultra2 and single-ended devices to operate together on the same
SCSI bus without inpacting Ultra2 performance and cable lengths. The AIC-7890
controller can support external High Voltage Differential (HVD) transceivers only
for Ultra data rates.
