Exam 11: HCIE-Storage

When a Simpana backup client failed to perform the backup task, the status reported the following error "failed to connect to indexing process from client [client] to [MediaAgent * MediaAgent * 8400 * 8402] .Error [Inability to connect to remote machine[MediaAgent] .Please check Network Connectivity or the machine may be down]." You check the client and the media service devices are normal. The possible reasons for this problem are:

The figure shows an N8500 (V200R001) NAS engine chassis. The two NAS engine nodes in the chassis form a two-node N8500 NAS cluster. Which description of the front-end and back-end network planning of the cluster is correct. (Multiple choice.)

A customer requires 60 TB of storage space available on an OceanStor V3 storage system to store service data. How many disks will be used if the customer installs 600 GB 15K RPM SAS disks and creates a pool with RAID 5 (8D+1P) using a low hot spare policy? (Select the closest number without considering the required data protection space.)

A file system in a clustered NAS system performs heartbeat synchronization between nodes. When the heartbeat is interrupted, the N8000 cluster is split into multiple small groups, resulting in data loss.  The N8000 provides a fencing function to avoid the occurrence of the split-brain issue.  Which of the following descriptions of the role of fencing correct?

Which of the following describes the correct steps of an Oracle database backup? 1, backup oralce control file 2, backup oracle archive log 3, oralce placed in backup mode 4, oracle placed in normal mode 5, backup oracle data files

What commands are installed there for viewing SCSI controller information on Linux systems with Qlogic HBAs?

In Huawei OceanStor 9000, the CA that processes write requests divides data into strips based on the protection level and writes data strips into non-volatile dual in-line memory modules (NVDIMMs) if the corresponding nodes. Then these nodes calculate and write parity strips into their NVDIMMs. After all these nodes have successfully written parity strips, the write operation is successful.

In a synchronous replication scenario, an application's peak write throughput is 16 MB/s, average write throughput is 500 KB/s, average write 1/0 size is 8 KB, private information overhead is about 11%, and the FC network bandwidth utilization rate is 70%. The throughput of the disaster recovery network must be at least ( ).

An enterprise has purchased two sets of HUAWEI OceanStor 9000 devices. To ensure the security of the data, one set provides storage for the production site and the other set is on the disaster recovery site to provide data redundancy. If the two Huawei Oceanstor 9000 storage system are to establish remote replication, which of the following is wrong?

Huawei Oceanstor 900 adopts erasure code technology to protect the data. If an office has six nodes, and the customer wants to have one office, ( Article broken three cases of the disk) . There are three cases of the broken disk, you can still guarantee that the data can be restored. You can use the redundancy protection level: (Multiple choice.)

Which of the following descriptions about the InfoEqualizer features of the OceanStor 9000 storage system are incorrect. (Multiple Selections)

HUAWEI OceanStor 18000 Engine, SVP, Disk Enclosure, and PCI-e Switch Interconnection are applicable to certain rules and orders. Which of the following statement?
