NOTE: In the normal boot process even though the BMC is running while the system is shut down (Power LED is steady amber), it does not drive the External Health LED to steady green until +12VDC power from the bulk power supplies is applied.

The following steps describe the system boot process. Step numbers provided correspond to the steps in Table 5-31:

3)System power switch turns on bulk power supplies and fans, and releases RESET on all CPUs simultaneously, when toggled on.

5)Initial CPU firmware code fetch is PAL code from EEPROM in PDH, retrieved 4 bytes at a time by DMDC in Zx2 (No shared memory or I/O devices are available at this time; they are not initially configured).

5)Firmware code stack is initially in BBRAM in PDH, retrieved 4 byes at a time, through PDH and DMD buses.

5) PAL code configures all CPUs.

5)SAL code configures all platform CEC chips, including shared memory and all responding I/O devices.

5)Firmware code and stack are relocated to shared memory after all x4DIMM ranks in shared memory are configured and tested.

5)EFI Shell launches from shared memory, and cache lines are retrieved 128 bytes at a time by MEMC in Zx2.

6)The OS loader launches using the EFI device driver.

6) The OS boots and starts its own device drivers.

6)The OS can use runtime PAL and SAL calls, and ACPI features. These abstraction layers enable platform independence.

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.
