Linux on Power Systems servers

These are major content areas for information about using Linux® on Power Systems servers and Power Systems servers running Linux.

Linux on Power overview
IBM Power Systems servers allow you to run Linux applications, while taking advantage of POWER hardware performance, availability, and reliability features.
Installing and setting up Linux on Power Systems servers
You can choose from several different methods to install Linux on your Power Systems server and set it up for your environment.
Performance for Linux on Power Systems servers
You can adjust the performance of your system and applications by tuning some of the variables on your system. For example, you can synchronize threads, disable processor-heavy services, apply new or updated patches, and so on.
PCIe3 CAPI and PCIe3 FPGA compression accelerator adapters
The Generic Work Queue Engine (GenWQE) Linux device driver supports the PCIe3 LP FPGA Accelerator Adapter (FC EJ13; CCIN 59AB) by implementing a work queue to offload tasks to the Field Programmable Gate Array (FPGA).
NVMe namespaces on NED24 NVMe expansion drawer
The NVMe expansion drawer - 24 devices (NED24) allows up to 24 Non-Volatile Memory Express (NVMe) drives to be attached to it. The NED24 NVMe expansion drawer contains two ECMAScript Modules (ESMs). ESM 1 module is attached to NED24 NVMe expansion drawer ports 13-24 and NVMe drive port 2 (P2). ESM 2 module is attached to NED24 NVMe expansion drawer ports 1-12 and NVMe drive port 1 (P1).
Hybrid Network Virtualization
Single Root I/O Virtualization (SR-IOV) allows a single I/O adapter to be shared concurrently with multiple logical partitions, providing hardware level speeds with no additional CPU usage, since the adapter virtualization is enabled by the adapter at the hardware level. This performance comes at the cost of the loss of Live Partition Mobility (LPM) functionality. Hybrid Network Virtualization (HNV) uses Linux® active-backup bonding to allow LPM for the partitions that are configured with an SR-IOV logical port.
NVMe over Fibre Channel (NVMf-FC)
Linux on Power® supports attaching NVMf-FC LUNs in addition to SCSI-FC LUNs.
Managing your server with service and productivity tools
Linux on Power service and productivity tools are also known as RAS (reliability, availability, and serviceability) tools. This topic collection provides information about hardware service diagnostic aids, productivity tools, and installation aids for Linux operating systems on IBM servers based on POWER9, POWER8, POWER7 technology.
