The onboard 7899 Adaptec SCSI controller is also an Ultra3/160 controller.
Drives on channel B of this controller can be used for storing digitized media
for all configurations. Avid recommends that you do not stripe across the
Ultra3/160 PCI controller and the onboard 7899 controller. See “Internal
Disk Controllers” on page 2-11 for more 7899 controller information.
ATTO Technology ExpressPCI UL3D/160 Dual-Channel Controller
The ATTO Technology ExpressPCI UL3D/160 is a dual-channel
Ultra3 SCSI controller that supports Low-Voltage Differential (LVD)
peripherals (see Figure 4-2). The controller is offered to customers as a
means to use LVD devices in local storage environments.
• When used as primary storage, the UL3D/160 controller is limited
to PCI slot 7 in all configurations.
• This controller is a 64-bit capable board and must be installed in
the same PCI bus as the digital media board set (normally it
cannot be installed in PCI slots 2 to 5).
