An Object Storage Device (OSD) system stores data as objects, each of which includes the data itself, metadata describing the data, and user-defined attributes. This structure allows forefficient data management and retrieval, as objects can be easily indexed and accessed based on their metadata and attributes. This differs from traditional file systems where data is organized hierarchically.References: Dell Information Storage and Management V5 documents, ExamTopics.

A Brownfield infrastructure building process allows organizations to repurpose existing infrastructure components and provides cost benefits. Brownfield projects involve upgrading or integrating with existing systems and infrastructure rather than starting from scratch (as in Greenfield projects). This approach leverages the existing investments in infrastructure, reduces costs, and minimizes disruption while still achieving modernization and improvements.

The exhibit shows the architecture of a NAS (Network Attached Storage) system that processes file I/O operations. Both scale-up and integrated NAS systems can process file write and read operations as described. Scale-up NAS systems add storage capacity by adding more storage to existing nodes, while integrated NAS systems combine the NAS head and storage into a single unit.
