74 Red Hat OpenShift and IBM Cloud Paks on IBM Power Systems: Volume 1
Scale-out servers
IBM Power Systems scale-out servers for mission-critical workloads, as listed in Table 5-2, 
offer a strong alternative to commodity x86 servers. They provide a robust, reliable platform to 
help maximize performance, and help ensure availability.
Scale-out AIX, IBM i, and Linux servers are designed to scale out and integrate into an 
organization’s cloud and AI strategy. They deliver exceptional performance and reliability.
Table 5-2   IBM Power Systems: Scale-out servers
Scale-out servers for SAP HANA servers, as listed in Table 5-3 on page 75, deliver 
outstanding performance and a large memory footprint of up to 4 TB in a dense form factor. 
These servers help deliver insights fast although maintaining high reliability. They are also 
scalable: When it is time to grow, organizations can expand database capacity and the size of 
their SAP HANA environment without having to provision a new server.
