Red Hat Unveils Linux Clustering Solution

Adapted Version of Red Hat Linux 6.2 Delivers Advanced Security, Scalability and Availability for a Reliable Internet Infrastructure


Red Hat, Inc. (Nasdaq:RHAT), a leader in open source Internet infrastructure solutions, today announced the Red Hat High Availability Server 1.0, a specialized version of the award-winning Red Hat Linux 6.2 solution.

Red Hat High Availability Server is an out-of-the-box clustering solution that delivers dynamic load balancing, improved fault tolerance and scalability of TCP/IP based applications. It lets users combine individual servers into a cluster, resulting in highly available access to critical network resources such as data, applications, network services, and more. If one server in the cluster fails, another will automatically take over its workload. The Red Hat High Availability Server is ideally suited to web servers, ftp servers, mail gateways, firewalls, VPN gateways and other front-end IP-based applications where virtually uninterrupted service is required.

"The Red Hat High Availability Server is optimized specifically for ISPs and corporate customers who want to dramatically reduce the time needed for implementation," said Paul McNamara, vice president, Products and Platforms, Red Hat, Inc. "In today's demanding internet environment, server failure means lost revenue and diminished customer satisfaction. With this product, we are providing customers with a flexible, affordable, and highly available front end internet infrastructure solution. Because the Red Hat High Availability Server software can be installed on any off-the-shelf commodity hardware that supports Linux - it offers service providers and corporate IT departments an option for increased availability at a significant overall cost savings."

The product supports heterogeneous network environments, allowing individual members of the cluster to run Red Hat Linux or virtually any other OS including Solaris®, and Windows NT®. Because the Red Hat High Availability Server is an open source product, customers are free from expensive technology lock-in that often occurs with proprietary solutions.

New security features
The Red Hat High Availability Server has a number of inherent security features designed specifically for high availability web front end applications. Remote system access is disabled by default, and unused network services are not installed or started in the standard installation.

The Red Hat High Availability Server can be configured in two main ways. In Failover Services (FOS) mode, the system can be configured as a two node cold failover cluster ideally suited for applications where simple, affordable redundancy is needed such as firewalls, static web servers, DNS, and mail servers. In Linux Virtual Server (LVS) mode, the system can be configured as an n-node cluster consisting of a two node load balancer, which accepts requests and directs those request to one of any number of IP-based servers based on a configurable traffic management algorithm.

Red Hat High Availability Server 1.0 features and benefits

  • Easy Installation:
    The Red Hat High Availability Server is based on the award winning Red Hat Linux OS. Red Hat's engineers have created a special installation-class that installs only those packages that are needed with the clustering packages. The Red Hat High Availability Server is installed for optimal performance - saving time and hassle.

  • Higher performance and scalability:
    The Red Hat High Availability Server supports the scalability that meets the growth demands of today's highly dynamic IP environments. The number of cluster nodes is limited only by the hardware and network used. The product has advanced cluster features that provide high levels of performance including an ability to configure servers to bypass the load balancers when returning traffic back to the client, increasing the overall performance of the cluster. Additionally, because individual nodes can be taken off-line for maintenance or upgrades without interruption of service, the product eliminates costly downtime.

  • Maximized Flexibility:
    The Red Hat High Availability Server offers Systems Administrators a high degree of flexibility. In LVS mode the product supports four load balancing methods (Round Robin, Weighted Round Robin, Least Connections, and Weighted Least Connections) and three traffic forwarding techniques (IP Masquerading, Tunneling, and Direct Routing). Virtually every popular IP service is supported including Web (http), email, FTP, LDAP, DNS, and others.

  • Increased Security:
    The Red Hat High Availability Server has built-in security features designed to withstand common attacks. Systems Administrators can setup sand traps, providing for redirection of IP traffic from a potential attacker to a secure address. Out of the box, finger, talk, wall, and other daemons are disabled or not installed. In addition, multiple traffic routing and scheduling techniques along with virtual IP addresses allow you to create a security barrier for your network.

  • Availability:
    The Red Hat High Availability Server dramatically reduces the likelihood of system failure by quickly detecting component server and application failures and redirecting workload to the remaining servers in the cluster. If one or more servers fail, others take over with minimal interruption.

  • Excellent value:
    Uses inexpensive commodity hardware to lower your overall cost of purchasing and maintaining the system.

  • Support:
    A one year support package that includes standard hours installation and configuration assistance and 24x7 server-down support for two Linux Routers of a Piranha cluster, configuration of Piranha and Linux Virtual Server and any services required to run these applications, including httpd and ftpd, and configuration of Piranha and Linux Virtual Server for connectivity to one node behind the Linux Routers for either httpd or ftpd service.


Pricing and availability
The price of the Red Hat High Availability Server is $1995. It is available from the online store at or at select resellers. Red Hat High Availability Server includes a full year of installation and configuration support via telephone or the Web from Red Hat's global support staff.
