| Hardware and Software Components which make for high availability |
Framework Installation |
|
The high application up time demanded by modern Service Users is made possible by the use of redundant hardware with intelligent software working together. Delegates receive an in depth introduction to each component of the system. Public Network, Private Networks, heartbeats, quorum devices and much more are introduced and their working explained.
|
The basic cluster software that causes multiple machines to act in concert to deliver consistency and availability is called the Framework. Theory meeting with practice, the Framework is tested and its functionality demonstrated.

| Introduction to DiskSuite |
The Role of Device Groups |
|
Starting with local replicas and mirrored boot drive, the course member is introduced to basic concepts assuming no pre-requisite knowledge of the product. Coverage includes the advanced topics of Disk Replacement as well as Shared Disk Sets.
|
Data is mirrored for availability. The cluster uses device groups to interface with DiskSuite disk sets. The course member is given hands on experience in dealing with disk groups, that is in dealing with SVM through the cluster.

| Public Network High Availability |
Data Service Installation and Configuration |
|
It is usual for systems to have multiple Public Network connections. These need to be configured in order for maximum use to be made of them in terms of availability and/or load balancing. The course navigates the syntactical challenges involved in this step toward a fully configured cluster.
|
For users to experience the benefits of a clustered application steps must be taken to integrate it into the Cluster Framework. The software which achieves this is called a data service. Standard, ready made Data Services need to be intelligently configured. The course examines in detail HA-NFS or HA-Oracle configuration.
