Huawei H13-629 - HCIE-Storage (Written)
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:
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 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?
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.
When using OceanStor V3, you need to mount the file system snapshot to access the snapshot data.
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?
When using OceanStor V3, you need to mount the file system snapshot to access the snapshot data.
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 (_).
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?
