Features and benefits
Balanced chipset architecture Delivers optimal system performance through well-aligned bandwidths (system bus, memory, SP and I/O bandwidths are well balanced).
400 MHz, 128-bit system bus capability 6.4 GB/s system bus supports up to four Intel® Itanium® processors per node for optimal system performance.
High memory capacity The DDR Memory Hub (DMH) provides a maximum of 8 DIMM slots with an aggregate of 32 memory slots enabled per processor node. Maximum capacity supported per processor node is 128 GB using 4 GB DIMMs.
Two high bandwidth scalability ports per SNC and SIOH Provides sufficient system headroom for single-node or multiple-node and degraded configurations.
Four hub interface 2.0 connectivity Delivers 1 GB/s bandwidth per connection, providing multiple I/O configuration options and offering both flexibility and performance.
I/O pre-fetch engine and built-in cache Delivers full bandwidth on data return.
High performance PCI/PCI-X bridge support Provides support to all PCI/PCI-X I/O devices, from legacy PCI to higher performance PCI-X at 133 MHz.
Advanced platform RASUM Features such as hot-plug modules for processor and memory, Error Correction Code (ECC) protection and correction, memory scrubbing, Memory Device Failure Recovery (MDFR), multiple redundant I/O paths and error logging combine to yield a more reliable platform, reducing downtime for repair and ensuring data integrity across all interconnects and busses.
