Red Hat Cluster Suite
Low-cost high availability for enterprise applications
For applications that require maximum uptime, a Red Hat Enterprise Linux
cluster with Red Hat Cluster Suite is the answer. Specifically designed for Red
Hat Enterprise Linux, Red Hat Cluster Suite provides two distinct types of
clustering:
- Application/Service Failover - Create n-node server clusters for
failover of key applications and services
- IP Load Balancing - Load balance incoming IP network requests across a
farm of servers
With Red Hat Cluster Suite, applications can be deployed in high
availability configurations so that they are always operational-bringing
"scale-out" capabilities to Red Hat Enterprise Linux deployments.
For high-volume open source applications, such as NFS, Samba, and Apache,
Red Hat Cluster Suite provides a complete ready-to-use failover solution. For
most other applications, customers can create custom failover scripts using
provided templates. Red Hat Professional Services can provide custom Red Hat
Cluster Suite deployment services where required.
Red Hat Enterprise Linux 5 Advanced Platform
With the release of Red Hat Enterprise Linux 5 Advanced Platform, Red Hat
Cluster Suite and Global File System are now included in the subscription
offering.
Red Hat Cluster Suite and Global File System are still available as layered
offerings for Red Hat Enterprise Linux versions 3 and 4.
Technical Highlights
- Support for up to 16 nodes on Red Hat Enterprise Linux 5.
- Allows high availability to be provided for multiple applications
simultaneously.
- NFS/CIFS Failover: Supports highly available file serving in Unix and
Windows environments.
- Fully shared storage subsystem: All cluster members have access to the
same storage.
- Comprehensive Data Integrity: Uses the latest I/O barrier technology,
such as programmable embedded and external power switches.
- Service failover: Red Hat Cluster Suite not only ensures hardware
shutdowns or failures are detected and recovered from automatically, but it also
monitors applications to ensure they are running correctly and restarts them
automatically if they fail.
Red Hat Cluster Suite is supported for use with Red Hat Enterprise Linux
AS and Red Hat Enterprise Linux ES on x86, AMD64/EM64T, Itanium and POWER*. Like
