Chapter 2. Using the Eserver pSeries 690

This chapter discusses the Hardware Management Console for pSeries (HMC), system power control, and drives supported by the server.

Hardware Management Console (HMC) Overview and Setup

The Hardware Management Console (HMC) uses its connection to the processor subsystem to perform various functions. The main functions of the HMC include:

vCreating and maintaining a multiple partition environment

vDetecting, reporting, and storing changes in hardware conditions

vActing as a service focal point for service representatives to determine an appropriate service strategy

Note: The HMC is shipped with the pSeries 690 and is the main interface for configuring and managing resources on this system through the HMC virtual terminal window. Virtual terminal window refers to the operating system session on a particular window. You can have up to 16 virtual terminal windows.

All the tasks you need to maintain the interface, the underlying operating system, and the HMC application code are available by using the HMC's management applications.

For more information on the HMC, refer to the IBM Hardware Management Console for pSeries Installation and Operations Guide.

System Power-on Methods

Using the HMC to power on the managed system is recommended. However, the white power button on the media subsystem operator panel can be used to power on the managed system. The managed system will reboot in the same mode in which it was previously booted. (If the managed system was previously booted in partitioned system mode, all partitions will automatically start and run.)

Powering the Server On and Off

This section provides procedures for powering the server on and off.

Progress indicators, also referred to as checkpoints, are visible on the media subsystem operator panel display. The power LED on the media subsystem stops blinking and stays on, indicating the system power is on.

pSeries690 specifications

The IBM pSeries690, also known as the IBM eServer p690, is a high-performance server within IBM's line of Power Systems, designed primarily for enterprise-level workloads. Launched in the early 2000s, it distinguished itself as one of IBM's flagship offerings, aimed at delivering exceptional scalability, reliability, and processing power.

At the heart of the pSeries690 is the IBM POWER4 processor, a revolutionary architecture that significantly enhanced processing capabilities. The system supports multiple processor configurations, allowing businesses to customize performance based on their specific applications. Each pSeries690 can be configured with up to 32 POWER4 processors, providing a maximum processing power that is well-suited for demanding enterprise applications, complex databases, and large-scale transaction processing.

One of the standout features of the pSeries690 is its ability to handle massive amounts of memory — up to 1TB of total RAM. This is particularly advantageous for businesses that run memory-intensive applications or require high availability for critical tasks. The server’s advanced memory architecture contributes to faster data access and improved overall system performance.

Additionally, the IBM pSeries690 employs the innovative AIX operating system, which is tailored for high performance and reliability. AIX comes equipped with features such as dynamic logical partitioning (LPAR), allowing resources to be allocated flexibly and efficiently across different workloads. This technology supports virtualization, enabling multiple operating environments to run concurrently on a single physical server, optimizing resource utilization.

The pSeries690 also includes robust fault tolerance and reliability features. Redundant components, hot-swappable parts, and advanced error detection mechanisms ensure that the system remains operational even in the event of hardware failures. This reliability is crucial for mission-critical applications where downtime can lead to substantial financial losses.

Networking capabilities of the pSeries690 are enhanced by support for high-speed connections, including Gigabit Ethernet and the ability to integrate with various network topologies. This versatility facilitates seamless connectivity in complex IT environments.

In conclusion, the IBM pSeries690 remains a powerful and reliable choice for enterprises seeking to manage and optimize their most demanding workloads. Its combination of cutting-edge processing capabilities, expansive memory support, and robust virtualization features makes it a significant player in the realm of enterprise computing. As businesses continue to evolve, the core strengths of the pSeries690, especially in terms of scalability and reliability, ensure that it continues to meet the needs of demanding applications.
