IBM is committed to environmental protection across all of its business activities, from its operations to the design of its products and use of its technology.

IBM's program for the reuse and recycling of end-of-life equipment, managed by IBM Global Asset Recovery Services (GARS), has a goal of less than 3% by weight being sent to landfills or incinerated. In 2023, the number was 0.7%.

IBM LinuxONE is designed for sustainable computing. It is uniquely architected to handle the multi-workload needs of a modern scalable digital business with the highest qualities of service and efficiency, allowing you to grow your workloads with a minimal increase in energy use.

With the IBM Telum® II DPU, IBM Artificial Intelligence Unit (AIU) and IBM Spyre™ Accelerator, you can get real-time inferencing without boosting energy use.

The ability to run more applications in one environment without impacting performance, throughput, or availability can reduce your IT infrastructure's floor space, cooling requirements, and power consumption. And a 19-inch frame form factor means IBM LinuxONE fit easily into modern data center cooling containment systems for hot aisle/cold aisle configurations.

Energy efficiency has been a hallmark of IBM LinuxONE since the beginning. With each generation, IBM LinuxONE systems became more efficient as capacity grew. Capacity per kilowatt has more than doubled since the first generation.

Consolidating Linux workloads onto IBM LinuxONE can reduce IT costs, especially when the software licensing costs are priced per core, and can reduce physical space and power consumption. IBM provides several options for quickly estimating the environmental impact of an IBM LinuxONE system.

The TCO and CO2e calculator helps you estimate the total cost of ownership and emissions of an IBM LinuxONE system and see a comparison to x86. Answer just a few questions about hardware, workload type and software.

The Power Estimation Tool helps you estimate the power consumption and weight of a specific IBM LinuxONE configuration.

1. Log in to Resource Link. (A link is provided below.)
2. Scroll to Tools, then click Power and weight estimation.
3. Click the link for the LinuxONE model you are interested in.

Carbon footprint reports help you understand carbon footprint impact across the product lifecycle. They can help you see how a solution will allow you to progress toward your sustainability goals.

An IBM LinuxONE Emperor 5 can have up to 200 configurable cores, and each core can run many servers, meaning you can run thousands of virtual servers on one IBM LinuxONE system.

You might consider applications or middleware, including database and application servers, that:

• Are supported by a software vendor on multiple platforms, including Linux on Z or IBM LinuxONE. In this case, migration is relatively simple and there are no support issues.
• Have per-core pricing
• Have high availability requirements
• Have high security requirements
• Can benefit from close proximity to data on IBM LinuxONE. You can boost the performance and speed of your Linux applications by putting them on the same physical server as their data source.
• Have high I/O or transactional I/O. Because of its design, IBM LinuxONE excels at handling sustained high I/O rates.
• Have lower sustained CPU peaks and average memory needs. These are ideal workloads for IBM LinuxONE, which been designed to run multiple workloads at a consistently high CPU and memory utilization.

Expect the consolidation to include these phases:

1. Planning. Begin by assembling the stakeholders to decide which applications to migrate and how. Your plan will specify the time, risks, and owner for each migration task.
2. Proof of concept. Conduct a proof of concept to assess compatibility between the x86 and IBM LinuxONE environments, with a special focus on performance.
3. Education. Ensure the technical staff has the necessary skills to carry out the migration and maintain the new environment.
4. Building the environment. Prepare the new infrastructure for migration.
5. Implementation. Perform the migration. Communication between stakeholders is important during this process. 
6. Post migration. Document maintenance procedures.

IBM provides the ability to view energy and environmental data for your IBM LinuxONE system. You can use this data to understand your current energy use and to report progress towards your sustainability goals.

The Hardware Management Console (HMC) Environmental Dashboard, beginning with IBM LinuxONE 4, shows power consumption for a selected system and logical partition, for a selected time, with graphical and tabular formats. You can export the data to XLSX for use in reports.

You can also access key environmental and power consumption data, including historical data, using the REST-based HMC Web Services API. This allows you to integrate the data into data center infrastructure management (DCIM) systems and other software such as IBM Instana Observability and IBM Envizi. Data includes ambient temperature and humidity, heat load, exhaust temperature, system power consumption, and power on each line cord phase.

Client projects are available for the HMC, including:

• python-zhmcclient, a client library in pure Python designed to make the HMC Web Services API easily consumable for Python programmers
• zhmc-prometheus-exporter, a Prometheus exporter intended to make it easy to set up custom metric collections.

IBM LinuxONE, beginning with IBM LinuxONE Rockhopper 4, can conduct power reporting by logical partition (LPAR).

You can integrate HMC data into IBM Instana with the IBM Z HMC sensor, an optional feature of Instana Observability.

You might use the sustainability dashboard with Grafana to visualize major sustainability metrics of migrating workloads from x86 to IBM LinuxONE.
