The Power Systems platform is designed to help organizations realize
maximum efficiency through server consolidation and virtualization, energy
efficiency, security, availability, and management, among other elements.
This portfolio consists of both hardware and software targeted at all
types of organizations. The company has launched the POWER9 processor for
data-intensive workloads, offering I/O subsystem technology, including
next-generation NVIDIA NVLink, PCIe Gen4, and OpenCAPI. By unifying its
technology on the POWER9 processor and providing a common hardware
architecture for the former System p and System i, IBM is aiming to
provide organizations with increased flexibility and scalability.
In 2020, IBM reported that it is removing the legacy PCI-Express 3.0
peripheral slots and is moving to PCI-Express 4.0 peripherals. It is also
introducing a single-core version of the Power S922. IBM is extending the
flexible utility pricing it started offering in May 2020 for the Power
E950 midrange and Power E980 high-end systems to the entry Power S922 and
Power S924 machines.

The case for server consolidation has been gaining strength. It is
estimated that the labor required by an organization to maintain one small
application server can cost between $500 and $3,000 USD per month. This
price does not include extra requirements such as backup and recovery and
network connectivity. Also, an IBM study revealed that there is an
estimated 44 percent reduction in power consumption after consolidating
applications run on twelve legacy servers onto one IBM System p5 550.
The consolidation of the System i and System p portfolio into the unified
Power Systems architecture reflects IBM’s continuing shift into the
services realm. This consolidated package is being marketed along with the
robust PowerCare services to provide customers with a comprehensive
IBM customers may be confused by the company’s decision to consolidate
its products into a converged platform. Legacy customers may not fully
understand IBM’s current product names and support strategies, as they
differ from when these customers originally purchased their products.
Additionally, the company may be adversely affected by a weak global
economy, as well as mounting competition in the IT services sector.
