“Shared Disk” Clusters
Shared Disk clusters successfully meet the needs of companies that require capabilities beyond those of Shared Nothing clusters:
- Databases or file populations that are not practical to segregate or micro-manage
- Practical scalability beyond 2-3 server nodes
- Consistent system management across a large cluster
- Where system growth must occur easily, without the requirement to redistribute files/data or disturb users
Shared Disk clusters are simpler to use & manage
- This reduces Total Cost of Ownership (TCO) of the cluster configuration and its system management significantly
