Reasons for scaling a storage network beyond a single fabric on a local or wide-area basis include:
- Consolidation of servers, storage, backup, applications and data centers.
- Data protection and business continuance, including regulatory compliance.
- Technology replacement combined with business growth and new application needs.
- Ability to support more devices than a single fabric can support.
- Isolation and segregation of workloads, applications and customers.
- Interoperability and coexistence of heterogeneous technologies.
- Performance (bandwidth and latency) including lack of congestion.
- Support for more servers and storage devices for growth.
- Support for backup, recovery and business continuance.
- Block access, file access (NAS), or combination of block and NAS access.
- Ease of management, diagnostics and provisioning of resources.
- Span distances to maintain data accessibility on a local and regional basis.
