Add-On Options for Availability

High-Availability Add-On

Red Hat's High Availability Add-On provides on-demand failover to make applications highly available. The High Availability Add-On may be configured for most applications that use customizable agents, as well as for virtual guests. The High Availability Add-On includes failover support for off-the-shelf applications like Apache, MySQL, and PostgreSQL. When purchased with the Red Hat Enterprise Linux for SAP applications, the High Availability Add-On provides failover for SAP applications.

Resilient Storage Add-On

Red Hat's Resilient Storage Add-On enables a shared storage or clustered file system to access the same storage device over a network. By providing consistent storage across a cluster of servers, Red Hat's Resilient Storage Add-On creates a pool of data that is available to each server in the group, but which also is protected if any one server fails.

The Resilient Storage Add-On includes the High Availability Add-On that may be used to protect applications as well as storage.

Load Balancer Add-On

Red Hat's Load Balancer Add-On provides redundancy for Web serving, databases, networking, and storage. By creating a virtual address that can be directed to a real server for load balancing or traffic shaping, the Red Hat Load Balancer Add-On allows you to quickly add or remove servers or change balancing algorithms using a browser-based graphical user interface (GUI).

Add-On Options for Scalability

Scalable File System Add-On

Red Hat's Scalable File System Add-On provides support for file systems that are more than 16 terabytes in size. You can manage these large data stores using advanced features such as 64-bit journalling and advanced locking algorithms.

High Performance Network Add-On

Red Hat's High Performance Network Add-On delivers remote directory memory access over converged Ethernet (RoCE) for those times when low network latency and high capacity are important. Because RoCE bypasses system and kernel calls to place data directly into remote system memory with less CPU overhead, the High Performance Networking Add-On is ideal for high-speed data processing applications that require low latency, for speeding up cluster locking, or for scaling up applications on distributed systems without investing in specialized networking technologies.

Add-On Options for Management

Smart Management Add-On

The Smart Management Add-On includes Red Hat Network Management, and Red Hat Network Provisioning modules for use with Red Hat Network and Red Hat Network Satellite. It allows organizations to easily manage and update Red Hat Enterprise Linux systems using Red Hat Network or Red Hat Network Satellite.

Add-On Option for Lifecycle Management

Extended Update Support Add-On

The standard seven-year lifecycle for Red Hat Enterprise Linux ensures application binary interface (ABI) and application programming interface (API) stability throughout the support period with regular delivery of technology updates and security packages. However, for those organizations that wish to stay on a particular snapshot for an extended period of time, Red Hat offers the Extended Update Support Add-On, which extends the support period of an update for 18 months and delivers overlapping release support to give enterprise customers more flexibility.
