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

Scale-out NAS storage architecture is a type of distributed file system that enables the storage capacity of the system to be expanded as nodes are added. It allows the file system to grow dynamically as nodes are added, allowing for increased scalability and flexibility. This type of architecture is often used in large-scale storage systems, and is particularly useful for managing large datasets.

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.

Local replication is a technique that replicates data within the same array or the same data center1. Local replication can enable operational recovery in the event of data lossby providing fast and frequent point-in-time copies of data that can be used for restore and restart operations23.

Enables operational recovery in the event of a site-level disaster is not a benefit of performing local replication. Local replication does not protect data from site-level disasters because it replicates data within the same site1. To protect data from site-level disasters, remote replication is needed to replicate data at a remote site2.

Provides disaster recovery as a service offering is not a benefit of performing local replication. Disaster recovery as a service (DRaaS) is a cloud-based service that provides backup and recovery capabilities for an organization’s data and applications4. DRaaS typically uses remote replication to store data in cloud storage locations that are geographically dispersed4.

Reduces the time to perform data backups is not a benefit of performing local replication. Data backups are different from data replication because they create secondary copies of data that are stored separately from primary copies and can be retained for longer periods5. Data backups may use local or remote replication as part of their process, but they also involve other steps such as deduplication, compression, encryption and verificatio

Solid State Drives (SSDs) use flash memory to provide non-volatile data storage. Flash memory is a type of non-volatile memory that can be electronically erased and reprogrammed. Unlike RAM, flash memory retains data even when the power is turned off, making it ideal for permanent storage in SSDs. The primary types of flash memory used in SSDs are NAND flash, which is cost-effective and has high storage density, and NOR flash, which offers faster read speeds but is more expensive.

In a full mesh topology, increasing the number of FC switches leads to a higher number of inter-switch links (ISLs). These ISLs consume switch ports that would otherwise be available for node connectivity, thereby reducing the total number of ports available for connecting storage and compute nodes.

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.

A big data ecosystem leverages advanced processing and management techniques to handle large volumes of unstructured data, such as social media posts, videos, and sensor data. This enables organizations to derive valuable insights and make informed decisions. By applying methods like distributed computing and machine learning, businesses can extract meaningful patterns, trends, and relationships from data that traditional systems cannot efficiently manage.

Pre-integrated systems that deploy compute, network, storage, and management functions as a single engineered solution are referred to as "Vendor ready solutions." These solutions are pre-configured and optimized by the vendor to ensure compatibility and performance, reducing the complexity and time required for deployment compared to a DIY approach or service-based approach. This is especially beneficial for organizations looking to quickly implement an integrated system with minimal customization.References:
