Intel® 7300 Chipset
The Intel 7300 Chipset improves data movement across Intel Xeon processor 7400 series-based servers by increasing interconnect bandwidth,
optimizing system bandwidth, increasing memory capacity, and improving network traffic processing while reducing I/O latency.

The Intel 7300
Chipset also has 28 lanes of PCI Express* with support for third-party expanders for additional I/O.
Intel® Ethernet Server Adapter
Designed for Intel® Xeon® processors with features that distribute I/O processing across multiple CPU cores. Intel Ethernet Server Adapters are
optimized for virtualization and include technologies such as Virtual Machine Device Queues (VMDq), which off-load some hypervisor functions
to the network silicon, freeing processor cycles and improving overall system performance.

Server Platform Designed for Your Needs
Platform Features Enabled by the Intel 7300 Chipset with Data Traffic Optimizations Include:
• 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
bandwidth by up to 2x over previous-generation multi-processor platforms

• Significantly reduces data traffic on the DHSI providing lower latencies
and greater available bandwidth. The snoop filter manages data coher-
ency across processors with a directory of the current cached data,
eliminating unnecessary snoops and boosting available bandwidth

(up to 256 GB based on 8 GB
Fully Buffered DIMM)
• Increases memory speed to 1066 MHz
• Improves CPU utilization and lowers latency through features like low
latency interrupts, MSI-X (next-generation interrupt handling) and state-
