Resolution: Only thin LUN can enable deduplication.

When using CLI to configure Huawei hybrid flash storage, the operations involved in creating storage space include creating a storage pool, creating a LUN, and creating a LUN group. Creating a host is not involved in creating storage space.

When choosing between different types of SSDs, the main factor to consider is the trade-off between cost and reliability. SLC (Single-Level Cell) SSDs are the most reliable and have the longest lifespan, but they are also the most expensive. TLC (Triple-Level Cell) SSDs are less reliable than SLC SSDs, but they are also less expensive. MLC (Multi-Level Cell) SSDs are a good balance between cost and reliability, they are more affordable than SLC SSDs and more reliable than TLC SSDs.

HyperMetro allows the local and remote sites to run services at the same time, and a quorum server must be configured. Additionally, automatic switchover upon storage faults is supported. HyperClone can be configured for storage devices of different models and versions.

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.

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.

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.

Resolution: NFS is a network file system. With the continuous development of the network, this protocol version has gradually increased. There is already

The latest version of 4.1.

A, C, and D are all true statements about the functions of HyperClone. HyperClone allows you to back up data from a source LUN, and when the source LUN fails, service data can be recovered from any point in time before the fault occurred . Additionally, if a logical fault occurs on the source LUN, data can be reversely synchronized from the target LUN to the source LUN to recover services on the source LUN. Finally, multiple target LUNs can be created through HyperClone to provide the service data on the source LUN for multiple applications.

SAS technology offers full duplex transmission of data and higher throughput than SCSI, which makes it more cost-effective and efficient. SAS technology does not offer half duplex transmission of data.

Fibre Channel is a dedicated protocol used in enterprise-level SAN networks for communication between hosts and storage devices or between storage devices. It features high transmission efficiency, long transmission distance, and high security and reliability.
