An incident in a storage infrastructure refers to any unplanned interruption or reduction in the quality of an IT service, where the root cause is unknown. These disruptions can affect the performance, availability, or reliability of storage systems, and identifying the root cause is crucial for resolution and prevention of future incidents.

FC SANs components include network adapters, cables, and interconnecting devices. The interconnecting devices can be FC switches or FC directors, which are more scalable and reliable than FC hubs. The ports on these devices can be FC E_Ports, which connect two switches or directors together to form a fabric, or FC F_Ports, which connect to host or storage devices with FC N_Ports.

The FCIP (Fibre Channel over IP) protocol stack uses TCP (Transmission Control Protocol) to encapsulate Fibre Channel frames for transmission over IP networks. TCP provides a reliable, connection-oriented transport layer that ensures the ordered delivery of data, making it suitable for encapsulating the FC frames and transporting them across IP networks. This enables the extension of Fibre Channel networks over long distances using existing IP infrastructure.References:

NVMe (Non-Volatile Memory Express) uses an embedded PCIe (Peripheral Component Interconnect Express) controller to connect hosts to M.2 storage devices. This direct connection allows for high-speed data transfer and low latency, making NVMe suitable for performance-intensive applications.

The Management plane of the Software-Defined Data Center (SDDC) architecture provides a graphical user interface (GUI) and command-line interface (CLI) for IT administrators to manageand configure the infrastructure, including storage resources. The management plane is responsible for providing visibility, automation, and orchestration of the SDDC components. It enables IT administrators to monitor and manage the infrastructure, configure policies, and allocate resources as needed. Reference: Section 1.1 Introduction to Software-Defined Data Center (SDDC), page 5.

Target-based deduplication is a method where the deduplication process occurs at the target storage device. This method is commonly used by cloud service providers because it reduces the amount of data transferred over the network by eliminating redundant data before it is stored. This approach improves storage efficiency and reduces costs.References:= Dell Information Storage and Management V5 course materials
