Veritas Cluster Server from Symantec is an industry-leading high availability 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.
Veritas 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.
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; SAP, BEA, Siebel, Oracle Applications, Microsoft Exchange, and PeopleSoft as well as enterprise-class databases such as Oracle, DB2, SQL Server, and Sybase . In addition, Symantec continually provides support for new applications. Support for custom-built applications can also be added through Symantec Consulting.
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 only solution that can support all leading operating systems, including UNIX, Microsoft Windows, Linux and virtual platforms, as well as the widest range of heterogeneous hardware configurations. Using Cluster Server, customers can add high availability 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 to reduce training, administrative, and hardware costs.
Advanced virtual machine support
With virtualization technologies, multiple virtual machines are commonly hosted on a solitary physical server. A failure of that physical server can lead to a loss of availability for several applications. As a result, the need to make services highly available increases with the use of virtualization technologies. Veritas Cluster Server provides a single solution for clustering both physical and virtual systems. With Cluster Server, administrators can monitor an application running within a virtual machine and recover it in the event of a failure.
Availability across any distance
For mission critical applications that must remain online even in the event of a site failure, Veritas Cluster Server provides disaster recovery across any distance. Cluster Server allows organizations to deploy both local high availability and remote clustering for complete disaster recovery. With the single click of a button, 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 production servers and applications are constantly changing, regularly testing a disaster recovery strategy is critical to guarantee a successful recovery in the event of an outage. To better guarantee the success of the disaster recovery strategy, Veritas Cluster Server includes Fire Drill, a tool that simulates disaster recovery tests, reducing the time and expense of disaster recovery testing. Cluster Server is the only 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.
Simple to install, configure, and maintain
Symantec offers Installation and Upgrade Assessment Services to ensure server readiness for the Veritas Storage Foundation from Symantec, Veritas Storage Foundation for Windows from Symantec and Veritas Cluster Server from Symantec products. Veritas Cluster Server provides administrators with easy-to-use configuration wizards for simplified storage management and cluster implementation. The Cluster Simulator, a free download, allows cluster administrators to simulate application failover scenarios and familiarize themselves with 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. 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" or N+M "active - active" capability for maximum availability without the cost of a dedicated spare per application. When a failure occurs, Cluster Server can automatically choose the least utilized server and add repaired servers back into the selection pool when they rejoin the cluster. Advanced failover logic in Cluster Server ensures that application uptime is maximized and server resources are utilized as efficiently as possible. Additionally, when intra-cluster communication breaks down, it is possible that two systems in a cluster try to write to the same storage and cause data corruption. Cluster Server advanced data protection logic shields data from becoming corrupted when a split brain situation arises by providing arbitration over cluster membership decisions. This guarantees data integrity as well as availability of service. The membership arbitration is provided using SCSI III protocol utilizing an odd set of coordinator disks or optionally through a software solution that is enabled via a Coordination Point Server.
