Best practicesEdit online Set up a performant and resilient networking topology with PCI network adapters. High availability setupHigh availability setups for applications on Linux® on IBM Z® or LinuxONE typically use path redundancy for network connections.Performance tuningPerformance optimizations are strongly dependent on your workload and on your hardware and software environment.Managing PNET IDsPNET IDs represent a user-defined logical ID (name) of a physical network. The physical network represents the physical broadcast domain of a given network.Parent topic: Networking with PCI adapters and functions
