Chapter 3 Hardware Architecture 3-3
3.2 Intel Processors
The Sun Netra CP3250 blade server supports dual 64-bit low voltage Intel Xeon
(Harpertown) processors at 2.13 GHz with 12 MB of L2 cache and a 1066 MHz
system bus. This processor is designed for high-performance, low-power
communication, storage, and embedded applications. It is built on Intel’s new 65nm
topology. The following are the key features of the Harpertown processor:
■ Quad-Core processor optimized for high performance, low-power
communication, storage, and embedded applications.
■ Four complete execution cores in a single processor
■ Dual processor support (eight high-performance cores per Sun Netra CP3250
blade server)
■ FSB Parity Protection providing key reliability and data integrity features
■ Intel Smart Cache Technology
■ Enhanced 36-bit memory addressing
■ FSB address, data, and response parity protection
■ Enhanced Intel Speedstep Technology
■ Intel¨ Advanced Thermal Manager
■ Streaming SIMD Extensions 3 (SSE3) Support
■ Embedded life cycle support
3.3 Intel San Clemente MCH
The architecture of the Intel E7520 Memory Controller Hub (MCH) provides the
performance and feature set required for performance servers, with configuration
options that facilitate optimization of the platform for workloads characteristic of
communication, presentation, storage, performance computation, or database
applications. To accomplish this, the MCH has numerous Reliability, Availability,
Serviceability, Usability and Manageability (RASUM) features on multiple interfaces.
The following list provides key features on the MCH:
■ Supports two processors on dual independent point-to-point system buses
operating at 266MHz (1066MTS) or 333MHz (1333MTS)
■ Six PCI Express x4 ports. Each of these ports can be configured as x4, x8, or x16
ports interfaces
