Devic e Overview
The 89HPES24NT3 is a member of the IDT PRECISE famly of
PCI Expressswitching solutions offering the next-generation I/O inter-
connect standard. The PES24NT3 is a 24-lane, 3-port peripheral chip
that performs PCI Express Base switching with a feature set optimzed
for high performance applications such as servers, storage, and commu-
nications/networking. It provides high-performance switching functions
between a PCIeupstreamport, a transparent downstreamport, and a
non-transparent downstreamport.
With non-transparent bridging (NTB) functionality, the PES24NT3
can be used standalone or as a chipset with IDT PCIe SystemIntercon-
nect Switches in multi-host and intelligent I/O applications such as
communications, storage, and blade servers where inter-domain
communication is required.
Features

Four mapping windows supported
Each may be configured as a 32-bit memory or I/O window
May be paired to forma 64-bit memory window
–
Interprocessor communication
Thirty-two inbound and outbound doorbells
Four inbound and outbound message registers
Two shared scratchpad registers
–
Allows up to sixteen masters to communicate through the non-
transparent port
–
No limt on the number of supported outstanding transactions
through the non-transparent bridge
–
Completely symmetric non-transparent bridge operation
allows simlar/same configuration software to be run
–
Supports direct connection to a transparent or non-transparent
port of another switch
