IBM RSCT

	IBM RSCT IBM Reliable Scalable Cluster Technology (RSCT) is a set of software components that together provide a comprehensive clustering environment for AIX, Linux, Solaris, and Windows operating systems. RSCT is the infrastructure used by a variety of IBM products to provide clusters with improved system availability, scalability, and ease of use. It follows a list of main RSCT components: the Resource Monitoring and Control (RMC) subsystem. This is the scalable, reliable backbone of RSCT. It runs on a single machine or on each node (operating system image) of a cluster and provides a common abstraction for the resources of the individual system or the cluster of nodes. You can use RMC for single system monitoring, or for monitoring nodes in a cluster. In a cluster, however, RMC provides global access to subsystems and resources throughout the cluster, thus providing a single monitoring/management infrastructure for clusters. It is used for HMC DLPAR, sfp, invscout ... the RSCT core res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	IBM Hardware Management Console {{Refimprove, date=October 2020 Hardware Management Console (HMC) is a Physical / Virtual appliance used to manage IBM Systems including IBM AS/400, IBM System p, IBM System z, and IBM Power Systems. HMC supports command line (ssh) as well as web (https) user interfaces and REST API. Using an HMC, the system administrator can manage many systems and partitions. It can also be used for monitoring and servicing a system. Power Systems HMC Versions * HMC HMC V10 R1 M1010 for POWER8, POWER9 and POWER10 Servers * HMC V9, for POWER7, POWER8 and POWER9 models (POWER6 support was dropped) ** HMC V9R9.1.0 (Initial release - Support for both x86_64 and ppc64le based HMCs - dropped support for Classic GUI) * HMC V8, for POWER6, POWER7 and POWER8 models ( POWER5 support was dropped) HMC V8R8.7.0 (latest version) HMC V8R8.6.0 HMC V8R8.5.0 HMC V8R8.4.0 HMC V8R8.3.0 (Initial support for Enhanced+ GUI) HMC V8R8.2.0 ** HMC V8R8.1.0 (Initial release) * HMC V7, for POWER5, POW ...

	DLPAR Dynamic Logical Partitioning (DLPAR), is the capability of a logical partition (LPAR) to be reconfigured dynamically, without having to shut down the operating system that runs in the LPAR. DLPAR enables memory, CPU capacity, and I/O interfaces to be moved nondisruptively between LPARs within the same server. DLPAR has been supported by the operating systems AIX and IBM i on almost all POWER4 and follow-on POWER systems since then. The Linux kernel for POWER also supported DLPAR, but its dynamic reconfiguration capabilities were limited to CPU capacity and PCI devices, but not memory. In October 2009, seven years after the AIX announcement of DLPAR of memory, CPU and IO slots, Linux finally added the capability to DLPAR memory on POWER systems. The fundamentals of DLPAR are described in the IBM Systems Journal paper titled: "Dynamic reconfiguration: Basic building blocks for autonomic computing on IBM pSeries Servers. Later on, the POWER5 processor added enhanced DLPAR capabilit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	IBM High Availability Cluster Multiprocessing IBM PowerHA SystemMirror (formerly IBM PowerHA and HACMP) is IBM's solution for high-availability clusters on the AIX Unix and Linux for IBM System p platforms and stands for High Availability Cluster Multiprocessing. IBM's HACMP product was first shipped in 1991 and is now in its 20th release - PowerHA SystemMirror for AIX 7.1. PowerHA can run on up to 32 computers or ''nodes'', each of which is either actively running an application (active) or waiting to take over when another node fails (passive). Data on file systems can be shared between systems in the cluster. PowerHA relies heavily on IBM's Reliable Scalable Cluster Technology (RSCT). PowerHA is an RSCT aware client. RSCT is distributed with AIX. RSCT includes a daemon called group services that coordinates the response to events of interest to the cluster (for example, an interface or a node fails, or an administrator makes a change to the cluster configuration). Up until PowerHA V6.1, RSCT also monitored cluster node ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
