• Question 287:

  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 the InfoEqualizer 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.

• Question 288:

  A Huawei OceanStor 9000 is externally shared using NFS and CIFS at the moment.

  You want to set some parameters to improve the performance of the NFS mounted under the Linux operating system. Which of the following description is correct?

  A. Rsize / wsize, read and write the maximum size of each block, it is recommended to adjust to the maximum. General Linux operating system environment, the maximum value of 1M.
  B. Async, allowing asynchronous data write, synchronous write requirements. NFS server must brush each data into the hard disk before it can return success delay higher.
  C. Noatime, if you do not need to record the file access time, you can increase this parameter to avoid frequent access, modify the access time to open pin.
  D. Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.
