Application Responsiveness and Reliability with Intel®
7300 Series Chipsets with Data Traffic Optimizations
The Intel® 7300 Chipset with data traffic optimizations improve data movement
across Quad-Core Intel Xeon processor 7300 series-based servers by increasing
interconnect bandwidth, optimizing system bandwidth, increasing memory capacity,
and improving network traffic processing while reducing I/O latency as compared to
previous platforms. All these platform advancements help to match the improved per-
formance of the Quad-Core Intel Xeon processor 7300 series. The Intel 7300 Chipset
has 28 lanes of PCI Express* with support for third-party expanders for additional I/O.

Dedicated High-Speed
Interconnects (DHSI)
Interconnects (DHSI)
• DHSI is an independent point to point interconnect between
each of the four processors and the chipset. DHSI has
increased the memory bandwidth by up to 2x over
previous-generation multi-processor platforms.

3
64 MB Snoop Filter
• Significantly reduces data traffic on the DHSI providing
lower latencies and greater available bandwidth. The
snoop filter manages data coherency across processors
with a directory of the current cached data, eliminating
unnecessary snoops and boosting available bandwidth.
