Extend your advantage

The world is changing rapidly, and today’s IT infrastructure must do much more than just support core business activities. As competitors pick up the pace, you must securely, reliably and efficiently transform vast quantities of data into timely insight for better-informed decision-making. And to achieve all of this, you need systems that are highly optimised, secure, and able to adapt to new requirements as they emerge.

The latest IBM Power Systems servers, featuring IBM POWER9 processors, lead the market in performance, scalability, security and cost-efficiency. For organisations upgrading from the previous generation, the same transactional performance is achievable in less than half the physical footprint – so you can gain insights faster even as you shrink and simplify your infrastructure. And with improved per-core performance, the latest Power servers can cut your software licensing costs.

IBM offers a broad range of Power Systems configurations to meet practically any use case, from scale-out private clouds to GPU-accelerated high-performance computing, and from hyperconverged infrastructure to scale-up SMP enterprise platforms. Northdoor has decades of expertise in designing, sizing, deploying and supporting Power Systems solutions for blue-chip companies – so whatever your requirement, we can help.

Consolidate for success

Power Systems continues to support up to three different operating systems simultaneously – IBM AIX, IBM i and Linux (both big-endian and little-endian) – running on the powerful and highly mature IBM PowerVM hypervisor. In practical terms, this means that companies can choose from tens of thousands of enterprise solutions, including a comprehensive range of open source software.

PowerVM enables multiple virtual environments to run efficiently and in complete isolation from each other on the same physical hardware, seamlessly flexing resources up and down to match your changing business objectives. These capabilities mean that you can consolidate multiple mission-critical systems to a single Power server without concerns about security, availability or performance. Built-in software simplifies the management of physical and virtual resources, helping you to control energy usage while ensuring continuous availability for mission-critical applications.

Equally, PowerVM makes it easy to run private or public cloud services, keeping different environments completely separate without introducing an unmanageable administrative overhead. However you choose to take advantage of PowerVM, the ability to mix and match environments translates into reduced hardware requirements, higher utilisation of resources, and improved energy efficiency. Whether you are consolidating workloads to reduce data-centre costs or seeking a better way to meet changing business demands, IBM Power Systems has the answers.

IBM’s fully integrated approach to the design, development and testing of IBM Power Systems servers ensures that they meet the highest standards in the industry for reliability and security, making Power the ideal platform for serious enterprise workloads. Northdoor strengthens this built-in dependability with expert support and maintenance services perfected over more than three decades.

Unlock the value of data

The POWER9 architecture is ideally suited for the demands of big data, providing 2X performance per core, 6-9.5X CPU to Accelerator bandwidth and 1.8X more memory bandwidth than x86 processors. Innovations such as CAPI can enable order-of-magnitude improvements in analytics and machine learning, and open-source analytical tools really excel on the platform.

With faster analysis of big data on POWER9, your business can identify and act on opportunities for profit ahead of competitors. What’s more, IBM Power Systems provides sufficient performance to kick-start your AI projects, helping you steal a march on the competition.

Reinforce your business

For mission-critical workloads running on AIX, i or Power Linux, where even short periods of downtime are unacceptable, Power Systems continues to offer exceptional stability and resilience. Multiple points of redundancy in the system architecture eliminate potential single points of failure, making Power Systems the platform for choice for enterprises.

With the optional IBM PowerHA software, you can create high-availability clusters spanning different locations for the ultimate reassurance that your core systems will be available at all times. As with IBM PowerVM, these additional capabilities do not come at the cost of increased administration: IBM PowerHA keeps systems running and enables you to focus on other priorities.


Designed specifically for enterprise AI – but also ideal for supporting traditional IBM AIX, IBM i and Linux workloads – POWER9  is the only processor with state-of-the-art I/O subsystem technology, including next-generation NVIDIA NVLink, PCIe Gen4, and OpenCAPI, technologies that maximise data bandwidth across the entire system stack. These technologies have contributed to a number of record performances on industry benchmarks, putting POWER9 at the top of the stack for high-performance computing. As the pace of change rises across all industries, taking advantage of AI on Power Systems could be the key to staying ahead of competitors.

Power HA for IBM i

Dependable IT infrastructure has never been more vital. For the systems that support core business activities – sales, finance, communications, logistics, and so on – even brief outages can create enormous disruption to the organisation and damage to the brand. In a world where customers and partners may be online around the clock, and where interconnected global financial markets never sleep, losing the ability to transact business even for a few minutes could be disastrous. With PowerHA clustering technology protecting key systems, your organisation will be able to focus on core business issues, safe in the knowledge that critical data and business processes will always be available when they are needed the most.

External Storage for IBM i

Using internal disk storage for IBM i environments on IBM Power Systems certainly has advantages. It is simpler to have a single box for both processing and storage, and data transfer is extremely fast. So what are the key benefits of moving to external disk instead? In a nutshell, you’ll gain a dedicated, specialised platform for storing data that will provide more built-in functionality and easier expansion. Any storage capacity you deploy in an external array can also be shared with other servers, both within your Power landscape and in your distributed landscape. This means that you can invest in new capacity with more confidence and less risk of obsolescence.
