KFTHA
The KFTHA module is designed for high-speed, high-volume data transfers. The
KFTHA has four channels (called hoses) connecting (see Figure 4-2) to external I/O
buses. Each I/O bus may be a PCI bus (for 8200 systems and 8400 systems with
Windows NT systems), or a PCI, Futurebus+, or XMI bus (for 8400 systems with
OpenVMS or DIGITAL UNIX).
KFTIA
The KFTIA module has an internal PCI bus that connects to various kinds of I/O
devices at the front of the module. This internal integrated bus has, as shown in Figure
4-2:
•
An FDDI connector. Provides access to a local area network (up to 2 km) or an
office-type local area network (up to 100 m), depending on the optional daughter
card installed.
•
Three FWD (fast wide differential) SCSI connectors. Can be combined with
DIGITAL StorageWorks RAID controllers, storage cabinets and devices to access
large amounts of SCSI disk storage.
•
One single-ended (SE) SCSI connector. Can be used to connect to a CD-ROM
drive.
•
PrestoServe NVRAM. Optional daughter card for DIGITAL UNIX systems only.
•
Two Ethernet connectors
The KFTIA module also has one hose to connect to an external bus. The bus may be a
PCI bus (8200 systems and 8400 systems with the Windows NT operating system) or a
PCI, XMI, or Futurebus+ bus (8400 systems with OpenVMS or DIGITAL UNIX
systems).
