Intel® E8870 Scalable Node Controller
(SNC) Datasheet
Product Features
s Intel® Itanium® 2 Processor System Bus
— Itanium 2 processor system bus
interface (44-bit address, 128-bit data)
at 400 MHz data bus frequency
— Full multiprocessor support for up to
four Itanium 2 processors on the system
bus
— Parity protection on address and control
signals
— ECC protection on each 64-bit chunk of
the 128-bit data signals on the
Itanium 2 processor system bus
— Eight-deep in-order queue
— Non-blocking transaction handling::
Transactions receive Normal
Completion, Retry, or Defer;
All transactions normally deferred;
No chipset snoop stalls
— GTL+ bus driver technology
— Chipset adds only one load to the
system bus
s PC1600 DDR SDRAM Memory via DDR
Memory Hub (DMH)
— Supports up to four DMHs
— 1, 2, 3, or 4 different types of DIMMs
per branch channel
— Supports 128-, 256-, 512-, 1024-Mb
devices in X4 and X8 configurations
— Supports from 512 MB (128 Mb
devices) to 128 GB (1 Gb devices) of
memory in 128 MB increments
— 6.4 GB/s peak bandwidth
— Server Error Correction Code corrects
for any single failed X4 memory
device, and limited correction on data
errors from X8 memory devices
— ECC with error correction and periodic
scrubbing of the memory
s Scalability Port (SP)
— Two SPs with 3.2 GB/s peak bandwidth
per direction per SP
— Bidirectional SPs for a total bandwidth
of 12.8 GB/s
s Firmware
— Firmware hub interface for processor-
specific firmware
s Reliability, Availability, and Serviceability
(RAS)
— Sideband access to configuration
registers via SMBus or JTAG.
— End-to-end ECC for all interfaces
— Fault detection and logging
— Signal connectivity testing via
boundary scan
s Packaging
