With the release of the IBM Power10 family of servers, OEDIV reviewed the opportunity to optimize and streamline its operations. In the context of foundation criteria, including security and stability, the team looked at ways to enhance availability, capacity, performance and sustainability. Ultimately, OEDIV is focused on serving customers’ desires for flexibility, economy and capability, and highlighted IBM Power10 as the ideal platform to support these ambitions.
Multiple Power10 features combine to create a compelling proposition for OEDIV, with virtualization and automation offering critical business advantages. By combining advanced technologies, OEDIV is able to streamline and optimize its operations, increase sustainability—exceptionally important in the energy-hungry compute-intensive world—and deliver enhanced customer service.
With these layered objectives in mind, OEDIV was attracted by specific features of the Power10 architecture, and chose four new IBM Power E1080 servers as the next phase in its infrastructure journey.
Virtualization for improved efficiency
Several interlocking capabilities of IBM Power10 enable OEDIV to significantly improve its IT efficiency. Virtualization ensures processor and memory capacity can be shared and optimized. “IBM Power10 offers greatly improved resource allocation capabilities and cost savings while ensuring we gain the maximum possible benefits for key issues such as availability and performance,” Münch reports.
OEDIV uses IBM Power Private Cloud with Shared Utility Capacity technology (formerly known as Power Enterprise Pools 2.0), which creates a shared pool of compute and memory resources. From the single resource, OEDIV allocates capacity tailored to each SAP S/4HANA instance in the most cost-efficient manner. The solution ensures that OEDIV avoids over-investing in capacity that might be unused, while each customer is provided with the optimal performance for its specific requirements.
Essential high availability
With IBM Power Private Cloud with Shared Utility Capacity, processor and memory usage is tracked based on average usage by the minute. If a hardware server requires maintenance or experiences technical issues, then the workload can be moved seamlessly to other remaining systems. While more resources will be used on those servers, the total capacity and payment will stay the same.
OEDIV uses the IBM PowerVC solution to orchestrate deployments, manage the storage area network, LPARs and more, centrally. In addition, OEDIV deploys IBM Cloud® Management Console technology for capacity planning, which provides real-time insight and reporting that helps predict likely requirements.
To manage storage, OEDIV uses 20 IBM Storage Virtualize nodes, capable of integrating with systems from multiple vendors, to help maximize availability and optimize utilization of space in available arrays. For its high-performance SAP S/4HANA environment on IBM Power, OEDIV relies on eight IBM Storage FlashSystem® storage solutions.
Speed of service
To create operational flexibility, OEDIV uses IBM PowerVM® software to create multiple independent virtual machines (VMs), also known as LPARs, on each server. According to customer preference and type of application, the company offers multiple operating systems, including Red Hat® Enterprise Linux®, SUSE Linux Enterprise Server, including Red Hat Enterprise Linux (link resides outside of ibm.com), SUSE Linux Enterprise Server (link resides outside of ibm.com), IBM AIX®, and IBM i. OEDIV runs more than 1,500 LPARs across its landscape of Power9® and Power10 servers, with more than 1 PB of available memory and 6,500 processor cores.
“The ability to deploy different operating systems and the multicloud configurations enables OEDIV to offer more choice even as we adopt standardized, scalable solutions,” explains Münch. “Standardization and automation are important factors, as our customers expect provisioning times, even for large-scale, complex SAP S/4HANA solutions, to be similar to times experienced in public clouds.”
Naturally, when running premium services, outages for technology upgrades are not acceptable. With a constant flow of requests from customers to create, delete, move and resize their SAP solutions, OEDIV relies on IBM virtualization configuration management, IBM PowerVC, to manage the workflow and on IBM Power Live Partition Mobility (LPM) to move workload online as necessary.
“We typically manage more than 1,500 Live Partition Mobility operations each month, an extreme example of the flexibility that the IBM Power platform provides,” says Münch. “This is an enormous volume. IBM Live Partition Mobility enables us to complete all kinds of maintenance tasks even while we deliver continuous service to customers.”
Automation and standardization
OEDIV handles many hundreds of requests from customers each month for additional cores to be allocated to their SAP systems. Very high customer service levels become possible with Power10, especially when combined with solutions such as Red Hat Ansible® Automation Platform and IBM PowerVC.
“The ease of management and unmatched flexibility combined with automation on the IBM Power platform has typically cut 30 minutes from many standard maintenance tasks, saving perhaps 200 hours each month,” comments Münch. “Where previously tasks might require level-three support technicians, IBM PowerVC provides an intuitive abstraction layer that enables staff to complete the work safely, quickly and efficiently.”
Performance improvements
Naturally, the move to the next-generation IBM Power10 platform, which offers expanded processor and memory capacity, also delivers valuable processing improvements.
“On average we see up to 15% performance boost with Power10, which in turn reduces costs for customers thanks to improved CPU performance and lower core allocations for their systems,” says Münch. “The increased Power10 processing power means we can deliver greater compute capacity within the same footprint, with up to 240 cores per server, and with more memory, leading to a 10% improvement in memory cost efficiency.”
He continues: “Furthermore, by using the latest Power10 processors and IBM Power Private Cloud with Shared Utility Capacity, we achieved up to 25% cost savings for SAP HANA on IBM Power. And in the LPARs running IBM AIX we see cost savings of 16.6%. And with IBM PowerVC and Red Hat Ansible Automation Platform, we can provision systems more efficiently and 20%–30% faster, more-efficient system provisioning.”
Sustainable computing
OEDIV also keeps a close watch on its environmental objectives, looking at electrical consumption, cooling and recycling of equipment among many measures. In addition, with a very large infrastructure footprint, asset lifetime and lifecycle can impact total sustainability metrics. The IBM Power servers are built using recycled materials where possible, and with end-of-life recycling—up to 99.2%—in mind, too.
“When compared to x86 servers, we find that the IBM Power servers last longer by about 30% without failures or issues,” says Münch. “Our installed base of IBM Power servers offers greater scalability, and our systems operate for a greater time span before we need to renew.”
