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.
Understanding your storage networking objectives, along with what level of scalability and resiliency you require, is integral to developing your storage network design. Attributes and service requirements associated with scaling a storage network include:
- 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.
