Virtual machines contain large databases.

The storage is connected directly to the virtual machine, including RDMs, directly to iSCSI or NFS.

Virtual machines contain large databases.

The virtual machine is deployed in the AIX operating system.

Virtual machines contain non-Microsoft family applications.

Database applications are one of the important applications supporting storage arrays.Different application configurations and parameter settings may affect the service performance. In order to store arrays (such as OceanStor V3 series storage) with SQL server applications with the best performance, which of the following statements is wrong:

SQL Server database instance memory size and recovery mode of choice has no effect on the performance of the database.

OLTP database generally have a large number of random write, it is recommended to choose RAID 10 to store data.

In order to improve write performance, all SQL server database data stored in the LUN write strategy is configured to "write back the image".

Because the size of the SQL server page is 8K, in order to ensure the best performance of the database, NTFS allocated block size should not be less than 8KB.

SQL Server database instance memory size and recovery mode of choice has no effect on the performance of the database.

In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkit inspection found that "multi-path state detection "does not pass the inspection report. It is found that there are two routes in the 4 paths of the VIS6600T device's 0 node to each LUN of the array. The path status is disabled. According to the analysis, the switch port connected to port 0 of port A0 of node 0 on node 0 of the VIS6600T is visible on the optical switch.

In addition to path failover, multipathing also provides load balancing. Load balancing is the process of distributing I / O load across multiple physical paths.

In the event of a path failover, the virtual machine I / O delays Nintendo pump by 60s.
