Device Overview
The 89HPES24NT3 is a member of the IDT PRECISE family of
PCI Express switching 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 optimized
for high performance applications such as servers, storage, and commu-
nications/networking. It provides high-performance switching functions
between a PCIe upstream port, a transparent downstream port, and a
non-transparent downstream port.
With non-transparent bridging (NTB) functionality, the PES24NT3
can be used standalone or as a chipset with IDT PCIe System Intercon-
nect Switches in multi-host and intelligent I/O applications such as
communications, storage, and blade servers where inter-domain
communication is required.
Features
High Performance PCI Express Switch
Twenty-four PCI Express lanes (2.5Gbps), three switch ports
Delivers 96 Gbps (12 GBps) of aggregate switching capacity
Low latency cut-through switch architecture
Support for Max Payload size up to 2048 bytes
Supports one virtual channel and eight traffic classes
PCI Express Base specification Revision 1.0a compliant
Flexible Architecture with Numerous Configuration Options
Port arbitration schemes utilizing round robin
Supports automatic per port link width negotiation (x8, x4, x2,
or x1)
Static lane reversal on all ports
Automatic polarity inversion on all lanes
Supports locked transactions, allowing use with legacy soft-
ware
Ability to load device configuration from serial EEPROM
Ability to control device via SMBus
Non-Transparent Port
Crosslink support on NTB port
Four mapping windows supported
Each may be configured as a 32-bit memory or I/O window
May be paired to form a 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 limit on the number of supported outstanding transactions
through the non-transparent bridge
Completely symmetric non-transparent bridge operation
allows similar/same configuration software to be run
Supports direct connection to a transparent or non-transparent
port of another switch
