[. . . ] DATASHEET ADD ONS FOR RED HAT ENTERPRISE LINUX WORKLOAD AND MISSION CRITICAL PLATFORM ENHANCEMENTS In conjunction with Red Hat® Enterprise Linux®, Red Hat offers a portfolio of add ons to extend the features of your Red Hat Enterprise Linux subscription. Add ons to Red Hat Enterprise Linux tailor your application environment to suit your particular computing requirements. ADD ON OPTIONS FOR AVAILABILITY MANAGEMENT High Availability Add On Red Hat's High Availability Add On provides on demand failover services between nodes within a cluster, making applications highly available. [. . . ] This add on includes the Global File System 2 (GFS2) for supporting all nodes within that cluster. Each server in a cluster has direct access to a shared block device over a local storage area network (SAN) of up to 100 terabytes. Data and cache consistency is ensured using a cluster wide locking mechanism called distributed lock manager (DLM) to arbi trate access to the storage. Each member of the cluster thus has direct access to the same stor Network Load Balancer Add On Red Hat's Network Load Balancer Add On provides redundancy for web serving, databases, net working, and storage. By creating a virtual address that can be directed to a real server for load add or remove servers or change balancing algorithms using a browser based graphical user interface (GUI). The Network Load Balancer Add On provides support for trans mission control protocol (TCP) and user datagram protocol (UDP) load balancing independent of applications. It is com posed of two major components: the Linux Virtual Server (LVS) ADD ON OPTIONS FOR SCALABILITY Scalable File System Add On advanced features such as 64 bit journaling and advanced locking algorithms. The Scalable File System Add On uses the XFS® on a single host, also performs well on smaller systems run www. redhat. com 2 DATASHEET ADD ONS FOR RED HAT ENTERPRISE LINUX 6 High Performance Network Add On Red Hat's High Performance Network Add On should be deployed when low network latency and high capacity are important. It delivers remote direct memory access over converged Ethernet (RoCE). Because RoCE bypasses system and kernel calls to place data directly into remote system memory with less CPU overhead, the High Performance Network add on is ideal for high speed data processing applications, for speeding up cluster locking, or for scaling up applications on distributed systems without investing in spe The High Performance Network Add On bypasses system and and places data directly into remote system memory with less CPU overhead.
