The Oceanstro 18000 hosts the VDI service with 20% and 80% of the front-end load read and write workload respectively, which requires 20000 IOPS for the business.

Choose 10K RPM SAS hard disk (assuming the average time to find 3ms) using RAID5. In this scenario, the minimum storage system hard drive configuration required is:

A.

600

B.

408

C.

387

D.

550

In the mirroring scenario of OceanStor VIS6600T, an engineer detected an abnormal mirroring alarm onthe VIS6600T. When you login to the ISM interface, you can view the mirror status of the volume in the corresponding logical disk group based on the alarm and find that the status of a volume in the mirror is NODEVICE.

The reason may be: (multiple choice)

A.

The disk on the array on which the failed mirrored volume failed

B.

Array where the failed mirrored volume is powered down

C.

The RAID array is degraded on the array where the failed mirrored volume is residing, and the hot spare is being rebuilt

D.

All optical links between the VIS 6600T and the array in which the failed mirror volume is located have failed

A computer center plans to purchase a set of Huawei Oceanstor 9000 products as a follow-up storage system. The requirements are as follows:

(1) The minimum storage system needs to provide a total bandwidth of 3-4GB / s

(2) storage space can reach 1PB, to meet a single file GB storage

(3) computer center room requires control deployed in a cabinet use

(4) Internal computer cluster nodes are now all InfiniBand network

Based on the above information, which of the following configuration suggestions do you think is more suitable for this project?

A.

Because computing tasks are designed for large file services, it is more appropriate to deploy with an 8-node OceanStor 9000 C node. The capacity on the use of 4TB SATA, to meet customer needs

B.

Using Oceanstor 9000 C Node combined with the total bandwidth and total capacity requirements, consider the 8-node configuration 4TB SATA full disk, backend 10GETOE + front-end IB networking

C.

From the reliability point of view, it is recommended to use theInfoEqualizer function to access the OceanStor 9000 storage through a domain name. The InfoEqualizer DNS segment needs to be considered and OceanStor 9000 back-end to interoperability

D.

OceanStor 9000 supports front-end 10GE TOE + back-end IB networking,the front-end is easy to log in and manage with the management PC interworking, considering this networking solution can reduce the cost of front-end IB switches.

The storage array provides the device LUN to the database. This LUN does not need to be labeled after being recognized by the host for the first time.

A.

True

B.

False

When using OceanStor V3, you need to mount the file system snapshot to access the snapshot data.

A.

True

B.

False

Enable SmartMigration on OceanStor V3 and start a migration task with SmartMigration. Before migration, suppose the LUN ID and the data volume ID of the source LUN are 1 and 2 respectively while the LUN ID and the data volume ID of the destination LUN are 3 and 4 respectively, what are they after migration?

A.

Source LUN: 1 and 3Destination LUN: 2 and 4

B.

Source LUN: 1 and 4Destination LUN: 3 and 2

C.

Source LUN: 3 and 1Destination LUN: 4 and 2

D.

Source LUN: 2 and 4Destination LUN: 1 and 3

When using OceanStor V3, you need to mount the file system snapshot to access the snapshot data.

A.

True

B.

False

An application's peak write throughput is 10 MB/s, average write throughput is 280 KB/s, average write I/O size is 4 KB, and the network bandwidth utilization rate is 70%. If OceanStor V3 storage systems are used to implement data disaster recovery based on asynchronous replication, Synchronization Method is set to Timed wait when synchronization begins, and the value of Interval is 4 hours, the expected duration to synchronize data is no more than 1 hour. So the minimum network throughput should be (_).

A.

1600 KB/s

B.

400 KB/s,

C.

15 MB/s

D.

10 MB/s

The user backup client has sufficient resources and the production network resources are relatively tight. The amount of data scheduled to be backed up weekly is 1-2T. The backup window is 3 hours, using source-side de-duplication, deduplication ratio of 3, thebandwidth utilization value of 0.8. Based on this, what kind of networking can meet the backup business needs and investment least?

A.

GE LAN-free

B.

10GE LAN-free

C.

FC LAN-free

D.

server-free
