Dell EMC Avamar is specifically designed for efficient disk-based backup and recovery. It incorporates inherent source-based data deduplication, which reduces redundant data at the source, optimizing storage and network resources before transferring data to the backup repository.

Service Planning involves making business use case decisions for the cloud service offering portfolio. This phase is critical for determining the strategic direction and business justification for cloud services, ensuring that they align with the organization's goals and deliver value.

The software-defined storage (SDS) controller function that gathers data about the components and brings them under its control and management is 'Storage discovery'. This involves discovering various types of physical storage systems available in a data center and collecting information about storage pools and storage ports for each system. This information is critical for effective management and provisioning of storage resources.

When the incident management team is unable to determine the root cause of an incident, the error-correction activity should be transferred to the Problem Management team. Incident Management primarily deals with restoring normal service operation as quickly as possible; when root cause analysis and error correction are required, it is generally within the purview of Problem Management to handle these tasks. Problem Management specializes in investigating and diagnosing the underlying cause of incidents to prevent future occurrences.

The 'Open and extensible' attribute of software-defined infrastructure (SDI) refers to the ability to integrate multivendor resources and external management interfaces and applications into the SDI environment using APIs. This ensures that the SDI can interact with and leverage a wide range of technologies and solutions, enhancing its flexibility and adaptability.
