Exploring PowerVM: A compelling alternative for virtualising your Linux workloads on IBM Power Systems

For organisations leveraging IBM Power Systems, virtualising Linux workloads is a strategic move towards increased agility, efficiency, and cost optimisation. While VMware remains a dominant player in the hypervisor space, IBM PowerVM offers a compelling alternative specifically designed to unlock the full potential of your Power on Linux infrastructure.

By exploring the advantages and considerations when adopting PowerVM for your Linux environments, you can make an informed decision for your virtualised landscape.

From a resilience and availability perspective, IBM Power was ranked number one in every major reliability category by ITIC for the 13th year running.

PowerVM: Unleashing the Power of Virtualisation for Linux on Power Systems

PowerVM stands as a robust hypervisor solution built from the ground up for IBM Power Systems. Designed to seamlessly integrate with AIX and IBM i environments, it extends its capabilities to virtualise Linux workloads, offering a feature-rich platform for consolidating, managing, and optimising your IT infrastructure.

Unparalleled Performance and Scalability: PowerVM leverages the inherent power and scalability of Power Systems architecture. Virtualisation capabilities are specifically designed to work in tandem with these systems, ensuring exceptional performance for your critical Linux workloads.

Advanced Virtualisation Features: PowerVM goes beyond basic virtualisation by offering functionalities like Logical Partitioning (LPAR) and Micro-Partitioning. LPAR enables granular resource allocation, allowing you to carve your Power Systems into isolated virtual servers perfectly suited for diverse workloads. Micro-Partitioning takes this concept a step further, dynamically allocating resources within a single LPAR, maximising use and efficiency.

Built-in Reliability and Availability: For mission-critical Linux deployments, PowerVM provides robust reliability and availability features. Live Partition Mobility allows seamless migration of running VMs between servers, minimising downtime for maintenance or upgrades. Additionally, built-in redundancy ensures high availability in case of hardware failures.

Integrated Management for Enhanced Flexibility: PowerVM Manager provides a centralised console for provisioning, managing, and monitoring your virtualised environment. This intuitive interface simplifies complex tasks and streamlines IT operations, fostering agility and responsiveness.

Security and Compliance at the Forefront: PowerVM prioritises security with integrated features like role-based access control and Secure Boot. Additionally, PowerVM’s compliance support simplifies the process of adhering to stringent industry regulations.

Optimizing Resource Utilisation: PowerVM excels at resource efficiency. Active Memory Sharing dynamically allocates memory based on real-time needs, eliminating resource waste. Similarly, processor pooling allows sharing processing power across VMs, ensuring each workload receives the resources it demands without over-provisioning.

Reduce Your Application License Costs: PowerVM offers significantly more configuration options compared to x86 platforms like VMware. With VMware, you typically configure a virtual machine with a specific number of virtual CPUs. However, PowerVM provides several parameters that guide the hypervisor on how many physical processors can be used and in what fractions. For newer PowerVM micro-partitions, this granularity goes down to 0.01 of a core, offering precise control over resource allocation.

One of the key advantages of this granularity is seen with applications like Oracle. IBM Power hard-partitioning allows you to license Oracle only for the CPU resources being used, rather than all the processor cores as required with VMware. This can potentially lead to significant reductions in ongoing licensing costs or free up Oracle licenses to support future expansion.

Seamless Integration within the IBM Ecosystem: PowerVM integrates seamlessly with other IBM solutions like Spectrum Virtualize and Spectrum Scale, enabling the creation of a comprehensive, high-performance storage and management ecosystem for your virtualized infrastructure. Additionally, PowerVM’s compatibility with both AIX and Linux environments fosters a unified virtualised landscape within your organisation.

Weighing the Considerations: A Balanced Approach

While PowerVM offers a compelling value proposition, it’s essential to consider the following factors for a well-rounded decision:

• Cost Considerations: Licensing costs and the upfront investment in IBM Power Systems hardware need to be factored in. However, potential savings from increased resource utilisation and consolidation of physical servers can offset these costs over time.
• Learning Curve: PowerVM offers advanced features that require a certain level of expertise to configure and manage effectively.
• Limited Third-Party Integrations: PowerVM’s tight integration with the IBM ecosystem can limit compatibility with certain third-party applications.
• Specialised Hardware Requirements: PowerVM relies on IBM Power Systems hardware, which may not be suitable for all existing environments.
• Alternatives in the Market: VMware and other hypervisors offer strong competition. Evaluating your specific needs and existing infrastructure is crucial.
• Vendor Lock-In: A certain level of dependency on the IBM ecosystem exists.
• Community and Support: While the PowerVM community is robust, it may not be as vast as some competing solutions.

The above need to be considered, but if you’re already running IBM i or AIX on IBM Power 9 or 10 systems, then you almost certainly have surplus processor and memory resources available that be used for Virtualisation.

Why Covenco for your PowerVM Assessment?

Covenco, with its expertise in IBM Power Systems and PowerVM, can help you seamlessly evaluate PowerVM as a viable alternative for your Linux workloads.  Additionally, Covenco is a VMWare accredited business partner with a high level of expertise in virtualisation across multiple systems and environments.

Our team of accredited IBM Power specialists can assist you in:

• Independent Assessment and Planning: We can conduct a thorough assessment of your current virtualized environment, workload requirements, and identify areas where PowerVM can optimise performance and resource allocation.
• Proof of Concept (POC): Covenco can help design and implement a PowerVM POC to demonstrate the tangible benefits it can bring to your specific use case. This allows you to experience firsthand the performance gains and cost efficiencies before committing to a full-scale migration.
• Migration Strategy and Execution: Our team can craft a comprehensive migration strategy tailored to your environment, ensuring minimal disruption and a smooth transition to PowerVM.

Beyond the migration process itself, Covenco offers unique value in helping you assess the total cost of ownership (TCO) of PowerVM compared to VMware (or other virtualisation technologies):

• Cost Transparency: We can conduct a TCO analysis that factors in not just the licensing costs of PowerVM but also the potential savings in areas like:

• • Reduced hardware footprint due to server consolidation with PowerVM’s efficient resource utilisation.
  • Lower energy consumption due to optimised power management capabilities within Power Systems.
  • Minimised downtime and improved operational efficiency through PowerVM’s high availability features.
• VMware vs. PowerVM Cost Comparison: Our expertise in both VMware and PowerVM allows us to objectively compare the ongoing costs associated with each platform. We can factor in licensing fees, support costs, potential hardware upgrades required for VMware to handle your workload, and the cost of managing a potentially more complex virtualised environment.
• Long-Term ROI Planning: Covenco will help you develop a long-term ROI plan that considers not just the initial migration costs but also the projected cost savings and performance improvements over time with PowerVM. This helps you to make a data-driven decision that aligns with your organisation’s budgets.
