All components of storage devices use the redundancy design to ensure system reliability. Redundant modules include controller modules, management modules, BBU modules, interface modules, power modules, and fan modules. This redundancy design helps to minimize the impact of hardware failures and ensure system reliability.

Deduplication is a data reduction technology that compresses large-size data blocks to reduce the physical storage capacity for storing data, thereby meeting increasing storage capacity requirements.

Deduplication can greatly reduce the amount of storage needed to store data, and can also increase the efficiency of data access.

A snapshot is a point-in-time copy of the source data that serves as a data backup accessible to hosts.

Snapshots are commonly used to recover data in case of accidental deletion or corruption, or to allow multiple users to access the same data without interference with each other.

A single-platter or multi-platter disk allows only one head to read and write data at a time. This means that the disk must be repositioned to read or write data to different locations, which can significantly impact the performance of the disk.

NAS (Network Attached Storage) is a type of storage system that provides file sharing services over a network. NAS systems use standard network protocols such as NFS (Network File System) and CIFS (Common Internet File System) to provide file-level access to data, allowing multiple users to access and share files stored on the NAS device. This makes it an effective solution for storing, sharing, and managing large amounts of data within an organization. Additionally, modern NAS systems can offer features such as data replication, snapshots, and data protection, which adds to the functionality of the storage solution.

A disk domain is a collection of physical disks of the same type and speed. If a disk domain has multiple disk types, it is not necessary that the storage pools within that disk domain have multiple disk types as well. Storage pools are a collection of physical disks within a disk domain that are grouped together to provide storage capacity. The storage pools can be created with different RAID levels and disk types, so it is possible to have a disk domain with multiple disk types and still have storage pools with only one disk type. It depends on how the administrator wants to configure the storage pool and how the storage is used.

IP SANs are not suitable for deployments that do not require high access speeds, as they are optimized for fast storage access. In this scenario, a more suitable storage solution would be a Network Attached Storage (NAS) system [1], which is designed for slower access speeds.

SmartKit is an O&M tool that integrates cloud computing, server, and storage. It cannot be used to monitor third-party devices, as it is only designed to monitor and manage devices in the SmartKit ecosystem.

If a disk is faulty, the process of recovering data on the faulty disk is typically done through a process called reconstruction. Reconstruction involves copying data from a healthy disk in a RAID array to the faulty disk. This can be done through software or hardware RAID controllers. The RAID controller will use the data stored on the other disks in the RAID set to recreate the data that was stored on the faulty disk. This process can be done while the RAID array is online, allowing the RAID to continue functioning while the reconstruction process is taking place. Once the reconstruction is complete, the faulty disk can be replaced and the RAID array can continue to function normally.
