In a data archiving environment, the archive agent is responsible for scanning primary storage to identify files that need to be archived. The agent looks for files based on specific criteria such as age, size, and access frequency, then initiates the archiving process by moving or copying the files to the archive storage. This helps in managing storage efficiently by freeing up space on primary storage.References: Dell Information Storage and Management V5 documents, ExamTopics.

Edge computing is a modern technology that enables data to be securely collected and processed at the point of creation, allowing for new value to be created from the data. Edge computing uses distributed computing resources such as routers and gateways to process data close to the source, which reduces latency, improves efficiency and reduces the overall cost of data processing. Edge computing also enables data to be securely collected and processed in a decentralized manner, which improves data security and privacy. Additionally, edge computing enables the data to be processed in real-time, allowing for faster responses and more accurate results.

HDFS (Hadoop Distributed File System) is a file system that provides a streaming interface using the MapReduce framework. HDFS is designed to store large volumes of data across many machines and provides high-throughput access to this data. The MapReduce framework allows for processing and generating large datasets with a distributed algorithm on a cluster. HDFS's architecture is optimized for handling large files and supports operations such as writing data once and reading many times, making it ideal for big data analytics and processing tasks.

Agent-based backup involves installing a software agent on the client system (in this case, a VM) that manages the backup process. The agent monitors the data on the client, processes it, and sends it to the backup device. This method provides granular control over the backup process and allows for more sophisticated features like incremental backups, compression, and encryption. Agent-based backups are commonly used in virtual environments because they provide detailed management and reporting capabilities for each VM, ensuring efficient and secure data protection.

The Dell EMC ViPR Controller is a software-defined storage (SDS) platform that abstracts, pools, and automates a data center’s physical storage infrastructure. It provides a unified storage management platform that simplifies storage provisioning, improves utilization, and automates storage workflows. ViPR Controller supports heterogeneous storage environments, making it a versatile solution for modern data centers.References: Dell Information Storage and Management V5, Software-Defined Storage Solutions,Dell Certification Resource

Data deduplication is a process that eliminates redundant copies of data, reducing the storage space needed. It works by identifying and storing only unique data blocks, replacing duplicate blocks with pointers to the original data. This significantly reduces the amount of storage required and optimizes storage efficiency.

A Fibre Channel Storage Area Network (SAN) typically comprises the following components:

• FC HBA (Fibre Channel Host Bus Adapters): These are the network interface cards that connect servers to the SAN.
• Switches: These devices are used to connect multiple HBAs and storage devices in a SAN.
• Fiber optic cables: These cables are used to connect the HBAs, switches, and storage devices, providing high-speed data transfer.

Cache tiering automatically allocates a large capacity secondary cache using Solid State Drives (SSDs) and Storage Class Memory (SCM). This method optimizes storage performance by dynamically assigning frequently accessed data to faster storage tiers, such as SSDs and SCM, while less frequently accessed data remains on slower storage tiers.
