The Itanium 2 8-way, 16-way, and 32-way server - TX7/i9000 and i6000 series has NEC's original chipset that enables very high-speed memory accesses throughout the system. In this paper, the Itanium2 32-way server - TX7/i9510 system architecture is described; the 8-way and 16-way server has the same system architecture as the 32-way TX7119510. The chipset presents a flat 32-way system image to the software. The TX7/i9510 supports partitioning for increased flexibility. The cell and the PCI unit can assign to each partition flexibly. The hardware components such as the service processor can have redundant configuration. With the combination of the TX7/i9510 chipset, the integrated Service Processor and Machine Check Architecture (MCA) of Itanium Processor Family (IPF) architecture, the TX7/i9510 realizes a new level of open system Reliability, Availability, Serviceability (RAS). The TX7/i9510 hardware also supports the cell hot plug feature and PCI unit hot plug feature. This paper describes overall system architecture of the TX7/i9510.
