HAO for RHEL on p Systems (POWER)

What is HAO for RHEL on p Systems?

 

Developed and supported by Sine Nomine Associates and incorporating Red Hat technologies, the High-Availability Option (HAO) for Red Hat Enterprise Linux on p Systems provides software and support tooling to implement clustered, highly available system services and data storage services on both big-endian and little-endian POWER hardware.

HAO provides workload distribution, cluster creation and management software and enterprise-level support for GFS2, a comprehensive cluster-aware file system that is aware of the p Systems hardware capabilities for zero down time service. The product enables cluster communications via TCPIP message transports, and provides the ability to cluster combinations of KVM guests and LPARs running RHEL on the same physical system or different physical systems (subject to the documented hardware and disk sharing configuration limitations supported by IBM).

 

Target Audience for HAO for RHEL on p Systems

 

HAO is intended as a general purpose clustering infrastructure component for all users of RHEL on p Systems who need to provide highly available system services and data storage systems on POWER-based hardware.

 

HAO for RHEL on p Systems  Features

 

HAO provides a comprehensive clustering and workload distribution solution for RHEL deployments on p Systems equivalent to the solutions provided on Intel hardware by Red Hat. The package includes:

  • Cluster failover infrastructure tooling
  • Cluster failover policy definition, management, deployment, and monitoring tools
  • GFS2 (a cluster-aware general purpose file system) and support
  • gluster support (a cluster-aware general purpose file system) and support (on RHEL 7)
  • Support for LPAR and KVM implementation
  • Load balancing and workload distribution software
  • Load balancing and workload distribution policy definition, mangement, deployment and monitoring tools

The package is designed to be functionally equivalent to the Red Hat Cluster Suite, and to leverage existing skills within your organization on cluster definition, application migration and management, and cluster operations.

HAO for RHEL on p Systems has been tested with popular commercial enterprise applications such as DB/2 and Websphere MQSeries high-availability requirements. SNA engineers can assist with implementing HA support for many products as part of separate services engagements.

 

HAO for RHEL on p Systems is a "Red Hat Ready" registered ISV Partner product.
