Implementation of SUN Cluster using VERITAS

* Implementation of sun clustering using VERITAS Cluster Management availability of data

management solution designed for heterogeneous enterprise environments and supports policy-

based failover of resources, cascading automatic recovery from consecutive failures

* Using VERITAS Cluster Server allows users proactively manage the availability of

services at the application level in clustered environments, which results in higher

overall information and data availability

* Designed and Maintaince of VERITAS Cluster Server was used for comprehensive

application availability management for both hardware and software resources in clustered

server configurations

* Implementation of Veritas Cluster for 100% availability of all services as well as

downtime is eliminated. In addition, tight integration between VERITAS storage and

availability management product lines provides faster fail-over and application recovery.

* VERITAS was used to ensure high availability for their applications and data.

* Managing and installations.of all VERITAS Cluster servers, clustering technologies and

clustered applications on local server clusters,

* Using Veritas making the ideal solution for increasing the availability of web, email

and other critical Solaris applications in rapid-growth environments

* Sun Cluster was implemented and designed to deliver high availability through automatic

fault detection and recovery, ensuring that mission-critical applications and services are

available when required

* Cluster software was designed and implemented for the enterprise level servers for

inframe-class reliability, availability, and scalability.and was used to delivers superior

performance and capabilities that will help to build, manage, and grow the enterprise by

enabling to create an environment that reduces and almost eliminates, potential downtime,

and provides continuous access to the software and services

Implementation of SUN Cluster

* Using Sun Cluster 2.1 and Solstice HA 1.3, providing support for both standard

(failure) and parallel applications.

* Implementation of Sun Cluster 2.2 was used for both Solstice DiskSuite and Veritas

Volume Manager under Solaris 7 Operating Environment. Sun Cluster 2.2 Highlights

* Managing the cluster using Sun Cluster Manager.

* Individual application failover, local application restart, and local network adaptor

failover for fast recovery.

* High-speed cluster interconnects and high-bandwidth networking deliver exceptional

throughput.

* Implementation of sun cluster servers for the applications to scale by using larger

servers and multiples of them concurrently. To users,

* cluster was Implemented and it appears as a single system, capable of providing near-

continuous access to application services, including databases, Web services, and file

services

* Sun Cluster delivers high availability through a combination of well-managed hardware

and software components. Availability was maximized by configuring the cluster without any

single points of failure, including the networks,

* Cluster interconnects storage, and software service components. Data integrity is

maintained by the cluster,

* The health of each individual node, along with its hardware and software components, is

constantly monitored. Failing or failed nodes are prevented from delivering services and

accessing data. Failed software components was restarted within the cluster, and failed

nodes was returned after the cluster repair.

* Implementation of Zero Failover process by which the cluster automatically relocates an

application from a failed node to a healthy one. When a failover occurs, clients may see a

brief interruption of service, but they are not aware that the application has been

rehosted on a different physical cluster node.

* A scalable application service leverages the multiple nodes in a cluster by running

multiple instances of the same application service concurrently on multiple nodes.
