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.

Storage virtualization does not enable servers to directly access storage hardware. Instead, it creates a virtual layer between the physical storage devices and the servers, allowing the servers to access the storage devices through a single interface. This virtual layer also allows the storage devices to be centrally managed, and can be used to reduce the limitations of physical storage capacity and hide the complexity of physical devices.

The main functions of the business continuity solution are to minimize the impact on the business service, ensure zero data loss and zero service interruption, and improve the utilization rate of the disaster recovery equipment. Predicting the disaster occurrence accurately is not a function of the business continuity solution.

RAID 0 is a data striping technique that involves distributing data across two or more disks, which allows for increased performance and capacity. RAID 0 does not provide redundancy, and if any of the disks in the RAID group fail, the data will be lost. RAID 5 and RAID 6 are both data striping techniques, but they also provide redundancy, which means that the data is still recoverable even if one or more disks in the RAID group fail. RAID 1 is a data mirroring technique, which involves writing the same data to two disks, and does not use data striping.

Nearline storage is a type of data storage that is classified based on data access frequency, with online storage being for frequent access, nearline storage for occasional access, and offline storage for rare access. Unified storage combines the features of online, nearline and offline storage into a single solution.

The correct order for the evolution of mid-range storage architectures is:

Fixed storage system configuration

Flexible hardware component configuration

Flexible software function configuration

Dual-controller active-active redundancy configuration

In the early stage, storage systems were fixed configurations with little flexibility. As technology progressed, the ability to change hardware components and software functions was added, allowing for more flexibility in the storage system. The last stage is the implementation of dual-controller active-active redundancy configuration, which provides high availability and failover capabilities in case of a hardware failure.

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.

If there are writes to the source LUN during a snapshot rollback, the rollback is performed before the writes are complete. This means that any data written to the source LUN during the snapshot rollback will be lost, since it will be overwritten by the snapshot data.

In storage, a hot spare is a spare disk that is pre-configured and ready to be used to rebuild data in the event of a disk failure in a RAID array. When a disk failure occurs in a RAID array, the data that was stored on the failed disk is rebuilt using the data from the remaining disks and the hot spare. The rebuild process is done automatically by the RAID controller, and it is done in a way that does not disrupt the normal operation of the RAID array. The hot spare disk is usually kept in a powered-on and ready state, so that it can be used immediately in case of a disk failure. It is also known as "hot spare disk" or "hot spare drive".

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.

Distributed storage systems are designed to support horizontal scaling, which means adding more nodes to the system to increase both computing capability and storage space. This enables the system to handle large amounts of data and large numbers of users. Distributed storage systems also support storage resource pooling and virtualization, which allows for efficient use of storage resources and easy management of storage.
