Using a service-focused approach allows the storage infrastructure to be managed based on the needs of the business or customers. This approach focuses on the delivery of services, rather than just the management of storage components or devices. When a service provisioning request is received, the service-focused approach provides a framework to determine the appropriate workflow to fulfill that request. This may include provisioning additional storage resources, modifying existing configurations, or other tasks to meet the service level agreements (SLAs) of the business or customer. Reference: Section 1.3 Service-Oriented Storage Provisioning, page 16.

Virtual LANs (VLANs) are used to segment a physical LAN into multiple logical LANs. This allows multiple networks to share a single physical LAN while maintaining the logical separation between the networks. Each VLAN is assigned a unique identifier and each network device is configured with the identifier of the VLAN it belongs to. This allows traffic from different VLANs to be identified and routed accordingly. VLANs provide an additional layer of security by ensuring that devices on one VLAN cannot access the traffic of another VLAN.
