KFTIA module
The TLSB module that provides the interface from the TLSB bus to I/O buses.
The KFTIA module has one port, known as a “hose,” to provide access to a single
PCI, XMI (8400 only), or Fu (8400 only) card cage. A system can
support up to three KFTIAs with the first one in node 8 of the TLSB.
KN7CC CPU module
The 300 MHz CPU module that uses one or two DECchip 21164 chips with a
superscalar pipelined design. Each CPU chip has two 8-Kbyte caches and a 4-
Mbyte backup cache implemented in RAMs. The KN7CC processor supports
writeback caching.
KN7CD CPU module
The 350 MHz CPU module that uses one or two DECchip 21164 chips with a
superscalar pipelined design. Each CPU chip has two 8-Kbyte caches and a 4-
Mbyte backup cache implemented in RAMs. The KN7CD processor supports
writeback caching.
KN7CE CPU module
The 440 MHz CPU module that uses two DECchip 21164 chips with a superscalar
pipelined design. Each CPU chip has two 8-Kbyte caches and a 4-Mbyte backup
cache implemented in RAMs. The KN7CE processor supports writeback caching.
KN7CF CPU module
The 625 MHz CPU module that uses two DECchip 21164 chips with a superscalar
pipelined design. Each CPU chip has two 8-Kbyte caches and a 4-Mbyte backup
cache implemented in RAMs. The KN7CF processor supports writeback caching.
KZASA
Fu adapter; FWD SCSI adapter.
KZMSA
XMI adapter to the SCSI (Small Computer System Interface), enabling
connections to nodes on a SCSI bus.
KZPSA
PCI adapter; fast wide SCSI controller.
ISE (integrated storage elment)
All DSSI storage devices, such as RF disks and TF tapes, are ISEs.
LCD (local disk converter)
Converts 48 VDC to +5V and +12V needed by the storage arrays in the DSSI PIU
(BA654).
