Itanium Processor Load Order

Each physical CPU core contains logic to support two physical threads. This results in up to eight physical threads, or the equivalent of 8 logical CPUs, when two processor modules are installed and enabled in rx3600 servers. The operating system kernel attaches one or more software processes to each available thread. In multiple processor servers, having more threads means all software processes are launched and executed faster.)

For a minimally loaded server, one Itanium processor module must be installed in CPU socket 0 on the processor board CRU, and its threads must be enabled by user actions. You can install an additional identical processor in CPU socket 1.

Processor Module Behaviors

All enabled CPUs and their threads become functional when the system powers on. Each thread acquires instructions from the CPU instruction and data caches to complete early self tests and rendezvous.

The CPU communicates with the PDH until memory is configured. After the memory is configured, the CPUs communicate with memory.

Local machine check abort (MCA) events cause the physical CPU core and one or both of its logical CPUs within that processor module to fail while all other physical CPUs and their logical threads continue operating. Double-bit data cache errors in any physical CPU core cause a Global MCA event that causes all logical threads and physical CPUs in the server to fail and reboot the operating system.

Processor Problem Identification

•A diagnostic LED only lights for physical CPU core errors, when a specific processor module is isolated. If there is any uncertainty about a specific CPU the CRU LED on the diagnostic panel is not lighted. Check the SEL for any errors or warnings.

•For physical configuration errors, for example, when there is no processor module installed in CPU socket 0, all the CRU LEDs on the diagnostic LED panel light for all the missing processor modules.

•No diagnostic messages are reported for single-bit errors that are corrected in both instruction and data caches during corrected machine check (CMC) events to physical CPU core. Diagnostic messages are reported for CMC events when thresholds are exceeded for single-bit errors. Fatal processor errors cause global and local MCA events.

Table 5-15and Table 5-16list the processor events that light and that may light the diagnostic panel LEDs.

INTEGRITY RX3600 specifications

The HP Integrity RX3600 is a high-performance server designed to address the demanding needs of enterprises that require robust computing capabilities, reliability, and scalability. Part of the HP Integrity server family, the RX3600 is built on the Itanium architecture, which is known for its exceptional processing power and advanced features that support mission-critical applications.

One of the main features of the RX3600 is its capability to handle multiple workloads with ease. The server supports up to 64 GB of RAM, allowing for efficient multitasking and enhanced performance in data-intensive environments. Its modular design also enables organizations to scale up their systems by adding additional memory or processors as needed, making it a flexible choice for growing businesses.

The RX3600 is equipped with HP's Integrity Virtual Machines (VMs), which provide virtualization capabilities that allow businesses to run multiple operating systems and applications on a single physical server. This not only maximizes resource utilization but also simplifies management by reducing the number of physical servers required in the data center.

Another significant characteristic of the RX3600 is its advanced reliability features. The server is designed with fault-tolerant components, including redundant power supplies and cooling systems. This ensures that the server remains operational even in the event of hardware failures. Additionally, HP's Error Correction Code (ECC) memory helps detect and correct data corruption, further enhancing the system's reliability.

For security, the HP Integrity RX3600 includes built-in features such as Secure Boot, which ensures that the server boots using only trusted firmware and software. This protects against unauthorized changes and vulnerabilities that could compromise data integrity.

In terms of connectivity, the RX3600 offers multiple I/O options, including advanced networking capabilities that support high-speed data transfer and improved bandwidth. This is critical for organizations that rely on data-intensive applications and need to maintain seamless connectivity.

Furthermore, the server supports a range of operating systems, including HP-UX and Linux, making it adaptable to various enterprise environments. Its robust performance, reliability, and scalability make the HP Integrity RX3600 an ideal choice for businesses looking to optimize their IT infrastructure and support their critical workloads with confidence.
