VERITAS Cluster Server is the clustering solution for reducing both planned and unplanned downtime. By monitoring the status of applications and automatically moving them to another server in the event of a fault, Cluster Server can dramatically increase the availability of an application or database. VERITAS Cluster Server can detect faults in an application and all its dependent components, including the associated database, operating system, network, and storage resources. When a failure is detected, Cluster Server gracefully shuts down the application, restarts it on an available server, connects it to the appropriate storage device, and resumes normal operations. Cluster Server can temporarily move applications to a standby server when routine maintenance such as upgrades or patches requires that the primary server be taken offline.
Comprehensive hardware and platform support
Most clustering solutions require identical hardware and operating system environments for implementing a clustering solution. This can be an expensive and restrictive solution since customers need to ensure platform parity in a cluster. VERITAS Cluster Server is the solution that can support all leading operating systems, including UNIX, Windows, Linux and virtual platforms, as well as the widest range of heterogeneous hardware configurations. Using VERITAS Cluster Server, customers can add clustering to the current infrastructure without having to purchase additional hardware. Organizations can mix and match the servers and storage within a single cluster and share storage infrastructure. Using the same tool across platforms reduces training, administrative, and hardware costs.
Out-of-the-box support for applications and databases
VERITAS Cluster Server provides off-the-shelf support for a wide range of applications, including, but not limited to, applications such as SAP, BEA, Siebel, Oracle Applications, Exchange, and PeopleSoft as well as enterprise-class databases such as Oracle, DB2, SQL Server, and Sybase. In addition, more agents are continually being developed to support upcoming new applications.
Availability across any distance
Building an infrastructure for high availability at a local site may meet many availability requirements of business, while other requirements may involve greater protection that spans across multiple locations. With one tool, VERITAS Cluster Server, organizations can deploy both local clustering and remote clustering for complete disaster recovery. With the single click of a button, VERITAS Cluster Server can migrate applications between single servers in a local data center or move all applications to a data center several thousand miles away.
Automated disaster recovery testing
Because data center servers and applications are constantly changing, regularly testing a disaster recovery strategy is critical to guarantee a successful recovery in the event of a system or site-wide outage. To better guarantee the success of a disaster recovery strategy, VERITAS Cluster Server includes fire drill, a tool that automates testing, reducing the time and expense of disaster recovery testing. VERITAS Cluster Server is the solution that integrates automated testing with a market-leading disaster recovery solution. Now administrators can make frequent changes to the IT infrastructure and simultaneously reflect those changes at a remote site. And because using Fire Drill does not disrupt production applications, it can be run as often as necessary.
Multi-cluster management and reporting
With the increasing number of applications and heterogeneous clustered servers distributed across multiple data centers, management of clusters can be painful. From the cluster management console of VERITAS Cluster Server, customers can now monitor, manage, and report on VERITAS Cluster Server implementations on different platforms from a single Web-based console. The VERITAS Cluster Server management capabilities increase administrator efficiency by providing enhanced visualization of the managed clusters, centralized control for global applications, and complete reports of each application's availability status. VERITAS Cluster Server also reduces application downtime by helping administrators avoid common cluster configuration mistakes, audit unexpected cluster configuration changes, and provide a standard way for administrators to detect and investigate cluster problems and track management history of all the managed clusters.
Simple to install, configure, and maintain
VERITAS Cluster Server provides administrators with easy-touse configuration wizards for simplified storage management and cluster implementation. Cluster simulator, a feature of Cluster Server, allows cluster administrators to simulate application failover scenarios and familiarize themselves with VERITAS Cluster Server. Cluster simulator helps administrators simulate high availability environments from their laptops and test multiple application failover scenarios without affecting production environments.
Advanced failover logicProduct Highlights
With VERITAS Cluster Server, IT administrators can set failover policies based on server capacity. VERITAS Cluster Server then chooses the best server for a specific application at the time of failure based on application needs and the current state of resources in the cluster. It allows true N+1 "roaming spare" capability for maximum availability without the cost of a dedicated spare per application. When a failure occurs, VERITAS Cluster Server can automatically choose the least utilized server and automatically add repaired servers back into the selection pool when they rejoin the cluster. Advanced failover logic in VERITAS Cluster Server ensures that application uptime is maximized and server resources are utilized as efficiently as possible.
