Regarding Huawei’s distributed storage multi-level caching technology, the small I0 write cache single-selected storage scenario, which of the following is the correct order ()①Enter
Based on the WAL log area of ​​the SSD cache disk, return to the host to complete the write operation. ②When the memory write cache reaches a certain level, the data starts to go down
Flashing â‘¢Data writing into RAM-based Write Cache â‘£Small IO will be written to the SSD cache of the node first, waiting to be aggregated into large IO Rewrite to HDD
Large e-commerce company A uses Huawei hybrid flash storage to ensure its core business. Regarding the chip technology used in it, the following
Which statement is correct ()
The following single-choice descriptions that do not belong to the features of the horizontally extended file storage function are:
In Huawei distributed storage, the block service asynchronous remote replication architecture is based on the block service cluster to build an asynchronous replication relationship.
Based on the difference data, periodically synchronize the data of the master and slave volumes. After the data synchronization of the last synchronization cycle is completed, the current synchronization cycle starts.
Initially, all data generated on the primary volume will be written to the secondary volume during this synchronization.
Which of the following is not a component that must be single-selected in the architecture of the NAS system?
Huawei’s hybrid flash storage supports the integration of NAS and SAN. The software protocol stacks of the two single-selection are completely parallel. In terms of resource allocation and
Convergence on the management plane.
The QoS characteristics of object services. For applications with different priorities, different buckets can be configured, and the TPS of the bucket can be controlled through QoS.
As well as the allocation of bandwidth resources; for VIP tenants and ordinary tenants in the same system, different QoS strategies can be configured to ensure high-quality
The quality of service for advanced tenants.
An enterprise purchased a set of Huawei hybrid flash storage system, and multi-selected plans to configure NAS services to facilitate file storage and
Sharing, which of the following options are correct in planning and design ()
A bank’s production center and disaster recovery center use Huawei’s hyper-converged storage, and replication between sites
The link is recommended to be within 3000 KM, the minimum connection bandwidth is not less than two-way 10 Mbps, and the average write bandwidth of the replication volume is less than that of remote replication
bandwidth.
The NAS storage system implements file system sharing, and the underlying protocol uses iSCSI for data transmission.
Single selection Huawei hybrid flash storage uses a RAID 2.0+ software architecture single-selection structure to realize the virtualization of the underlying media and the virtualized resources of the upper layer.
Simulate, solve the problem of rapid data reconstruction and intelligent allocation of resources at the same time.
A company purchased multiple sets of Huawei distributed storage, deployed them in multiple data centers, and used object service remote replication to build a disaster recovery system.
If these distributed storages are planned in the same area, then this area has one and only one default cluster, and other clusters are non-default clusters.
Identify the cluster.
A bank’s production center and disaster recovery center both use Huawei’s hyper-converged storage products. The two centers communicate Disaster recovery through asynchronous replication. The copied network type can support GE/10 GE/25 GE
Smart City A plans to purchase Huawei's distributed storage to store its traffic surveillance video. Which of the following products are available ()
Which one of the following descriptions about the unified namespace is incorrect?
