Exam 11: HCIE-Storage

When the client adopts the SMB 1.0 / 2.0 / 2.1 / 3.0 protocol, while performing file replication inside Huawei OceanStor 9000, it does not need to pass through the client, but directly in the system to tell the completion.

The OceanStor V3 storage system has 96 hard disks in one hard disk domain. To maximize the performance of the hard disk, it is recommended to use the LUNs in the hard disk domain. The total number of hard disks is not less than:

With Redhat linux enterprise 6 system the df and du commands allow you to see the mnt capacity, as shown below.  What causes the capacity shown to not be the same? redhat: ~ # df -h / mnt Filesystem Size Used Avail Use% Mounted on / dev / sdb 1008M 514M 443M 54% / mnt redhat: ~ # du -hs / mnt 40k / mnt

Which of the following statements regarding the Huawei Oceanstor V3 hierarchical storage and Smart Cache is correct?

To cluster the server's public IP address in an Oracle RAC deployment process, a private IP address is written to the / etc / hosts file, along with the Virtual IP address, cluster unique access IP address and public IP. Which of the following configuration is correct? (all subnet masks are 255.255.255.0)

Which of the following describes Youtube, Facebook and other content warehouse sites data storage? (multiple choice)

Client1 needs to read file X from Huawei OceanStor 900 and the node that responds to the read request is node A. Choose the process, which of the analysis is correct:

OceanStor 18000 hot backup strategy is set to high, all using 1TB hard drive when the hard disk domain, respectively, eight hard drives, 80 hard drives, 180 Hard disk, 280 hard disk, the system will be assigned how much hot spare space, in Terabytes?

Customers purchased 3 RH228H v2 hosts (with LPE12002-AP_8G HBA with 2 FC ports), 2 Oceanstor VIS6600T (a total of eight four-port 8G FC interface card, two 4-port 1GE interface card, two 8-port 1GE switch module), two Huawei OCeanStor S6800T, and 2 Brocade 300 switches to build VIS6600T 4-node cluster and pass two S6800Ts. The VIS600T cluster is mirrored. Each of the three hosts needs a standard dual-switch redundancy network connected to the VIS6600T4 node. Each Brocade 300 Fiber Channel switches need to use which number of FC ports?

In OceanStoe VIS6600T delivery scenarios, multiple vendors are often protected. To avoid unpredictable compatibility issues during project implementation you need to collect compatibility information before the project is implemented. The compatibility information collected below is in accordance with the specifications. (multiple choice)

Create LUNs on an OceanStor V3 storage system. Set the initial space allocation policy to be automatic. Create LUN 1, and 80% of its space comes from the capacity tier. Create LUN 2 in the same storage pool. It can be concluded that 0% of LUN 2's space comes from the performance tier.

Under the condition of synchronous replication, the peak write bandwidth of an application is 16 MB / s, the average write bandwidth is 500 KB / s, and the average write IO is 8 KB.  If the bandwidth utilization rate is 80%, then the disaster recovery end network bandwidth should not be less than:

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:

OceanStor V3 does not start up normally within 15 minutes after the system is powered on. What engineers can use to log in to the storage system in order to locate this fault? (Multiple choice.)

in a Huawei Oceanstro V3 smartVirtualization, eDevLUN and external LUNs are a one-to-one correspondence

To use the storage space of OceanStor V3 more efficiently, a customer has specified file system quotas for different departments. If a soft quota alarm is generated for the file system used by department A, which methods can be used to clear the alarm and ensure that new data can be successfully written? (Multiple Choice)

A customer's production network resources are tight, and the budget is small.  The current customer wants to introduce a backup solution in the existing configuration.  Based on this, what is the recommended networking backup method is most appropriate for this customer?

Huawei Standard Edition N8500 has two nodes the business mount Pubeth1 and Pubeth4. It opened the NFS service. NFS server except recovery after NFS guest. Client mount point can not be accessed into the directory for a long time without echo. What do you need to do to fix it?

Huawei OceanStor 9000 external shared mainly NFS and CIFS at the moment. Set some parameters to improve performance of NFS mounted under the Linux operating system. Which of the following description is correct?

When you install the Simpana backup client on a virtual machine and perform a backup, the backup job status becomes pending and reports an error message "Cannot decode packet header: invalid start signature ", which of the following may be the cause of this problem?
