You also need to be able to take advantage of broad expertise and proven preferred practices in systems management, applications, hardware maintenance, and more. The IBM® Flex SystemTM p260 and p460 Compute Nodes are IBM Power SystemsTM servers optimized for virtualization, performance, and efficiency. The nodes support IBM AIX®, IBM i, or Linux operating environments, and are designed to run various workloads in IBM PureFlexTM System. This IBM Redbooks® publication is a comprehensive guide to IBM PureFlex System and the Power Systems compute nodes. We introduce the offerings and describe the compute nodes in detail.
