Change management is a process that uses an orchestrated approval process to assist decision making using an agile methodology. It involves assessing the impact of any proposed changes on the existing system, and then authorizing and implementing the changes in a controlled manner. The goal of change management is to ensure that changes are made in a smooth and efficient manner, with minimal disruption to the existing system.

Archive is a type of data protection that is used to move primary data to lower cost storage and helps to enforce compliance requirements. It is a process of moving inactive data that is no longer needed for immediate use to a secondary storage medium. Archive uses data compression and deduplication techniques to reduce storage costs, and can also be used to help meet compliance requirements.

Flow control in FOP (File-Oriented Protocol) is a network performance attribute that ensures that packets are delivered in the same order they were sent. This is achieved by assigning each packet a sequence number, and then having the receiver send an acknowledgment back to the sender that it has received the packet and is ready for the next one. This helps to ensure that packets are not lost, and that they arrive in the same order they were sent.

Automated storage tiering is a feature of an intelligent storage system that allows data to be moved between tiers of storage based on usage patterns. This can provide better performance and cost savings by ensuring that data is stored in the most appropriate storage tier for its access patterns. For example, data that is frequently accessed can be stored in higher-performing storage tiers, while data that is infrequently accessed can be moved to lower-performing, lower-cost storage tiers.

Parity-based RAID protection uses fewer physical drives than mirroring to provide the same level of data protection. It does this by using error correction codes to detect and correct errors in the data. This allows for a much more efficient use of storage capacity, as it only requires the same amount of storage capacity as the actual data, rather than requiring twice the storage capacity as with mirroring. Additionally, parity RAID systems have the advantage of being able to recover from drive failures without having to wait for the data to be rewritten to the remaining drives, as is the case with mirroring.

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.

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 loss by 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
