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.

Huawei storage products typically use 3.5-inch HDDs, which are larger than their 2.5-inch and 1.8-inch counterparts and are more suitable for use in enterprise storage environments. 5.25-inch HDDs were commonly used in the past but have become obsolete in recent years. 8-inch HDDs have never been used for enterprise storage.

RAID 5 and RAID 6 can meet the requirements as they both improve data reliability by storing parity data on different disks. RAID 0 and RAID 3 do not store parity data on different disks, so they would not meet the bank's requirements.

Quality of Service (QoS) is a set of technologies used to ensure that network traffic is allocated resources according to predetermined priorities. The three main working principles of QoS are I/O Priority Scheduling, I/O Performance Assurance, and I/O Flow Control. I/O Latency Burst is not one of the working principles of QoS.

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.

The statements that describe the high reliability of the Huawei OceanStor all-flash storage system are A. It supports clusters consisting of multiple controller enclosures to improve the availability of the storage system, B. Interconnect I/O modules shorten failover time when a controller fails to provide better reliability, as compared with common I/O modules, and D. When a controller fails, l/Os of the faulty controller are redirected to another controller The host is unaware of the fault and services remain running properly. Statement C. Standard I/O modules shorten failover time when a controller fails to provide better reliability, as compared with interconnect I/O modules is false.
