pseries

Together, this family of hardware offers 64-bit environments for your application on Linux on pSeries at a low total cost of ownership.

In effect, pSeries has been able to leverage some of the iSeries technology that was initially derived from the zSeries systems.

In addition to supporting Linux in a partition, the new pSeries "Linux ready" systems can be used to run stand-alone Linux images.

If you are using a different distribution of Linux or different pSeries hardware, your procedures may vary from what you see here.

Linux for iSeries and pSeries is in the unique position as a development environment of offering many different compilers.

On smaller stand-alone pSeries Linux systems, it may be desirable just to connect an ASCII terminal or terminal server to the serial port.

One of the currently available POWER chips available for entry-level pSeries servers.

Linux distributions on both iSeries and pSeries systems run in a logically partitioned environment (LPAR).

This set of hardware is currently being expanded with introduction of POWER5-based systems in pSeries lines of IBM e-server products.

The iSeries and pSeries specific diagrams shown here illustrate the slightly different hypervisor structures.

On the POWER-based servers, both pSeries and iSeries servers, you can run your Linux applications on enterprise-strength reliable servers.

The pSeries servers offer industry-proven performance, scalability, and reliability.

The hardware was configured in a three-tier environment using various pSeries AIX servers.

iSeries and pSeries servers can use the VisualAge compilers from IBM, to generate well-optimized code for these systems.

A pSeries partition is booted using a partition profile that identifies its hardware resources.

This article steps you through the installation of Linux on a pSeries system.

The third area you need to plan is to have redundant VIO servers on the same physical pSeries or System P server.

As mentioned earlier, some smaller pSeries systems can also run single stand-alone Linux images without using partitioning.

The 55 percent CPU improvement was on a pSeries server with two Domino partitions.

Can I run any Linux application that has been compiled on a pSeries server, on the iSeries platform?

There is a maximum of 32 partitions per pSeries system with at least 32 processors on it.

This article covers the installation of Linux on a pSeries system.

Most Linux applications written on pSeries platform will run unmodified on the iSeries platform.

The pSeries test machine used was a p570 configured into multiple LPARs.

With the AIX 5. 2 operating system, pSeries processor resources for AIX or Linux are allocated as whole processors.

In summary, iSeries and pSeries systems have a lot in common in their support for Linux software in partitioned systems.

In our example, though, we used one IBM eServer pSeries 630 machine to migrate the database on two logical partitions.

The pSeries box is partitioned using the OpenFirmware to assign the system resources, such as CPU, memory, storage, and other devices.

With faster processors, such as the IBM pSeries 690, you could allocate as small as 1 CPU per partition.

Many pSeries devices use the typical device drivers for their device type.
