Automating the operations management process in a data center environment can help mitigate operational management risks. Automation can reduce the likelihood of human error, which can lead to outages or other disruptions. By automating routine tasks, such as patch management, configuration updates, and resource allocation, IT staff can focus on higher-value activities that drive innovation and improve the user experience. Additionally, automation can improve operational efficiency, reduce costs, and ensure operational agility, but it does not eliminate operational costs. Reference: Section 2.6.2 Automation of IT Operations, page 127.

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.

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.

To calculate availability, you need to calculate the total number of hours that the port is operational and divide it by the total number of hours in the week, which is 168. The total number of hours that Port 4 is operational in that week is 106.7, so the availability is 106.7/168 = 86.7%.
