Database applications are one of the important applications supporting storage arrays. Storage arrays, operating systems, file systems, and database application systems, etc.
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 application with the best performance, which of the following statement is wrong:
AOLTP database generally have a large number of random write, it is recommended to choose RAID 10 to store data.
BIn order to improve write performance, all SQL server database data stored in the LUN write strategy is configured to "write back the image".
CBecause 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.
DSQL 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. The received optical power is much lower than the rated power of the optical module.
What repair strategy of the fault contains the error?
AReplacing the optical module of port 0 in slot A0 of node 0.
BReplacing the light of the P0 port in the A0 slot of 0 node.
CReplacing the optical module of the port connected to port 0 of the corresponding 0-node A0 slot on the switch.
DReseat the FC interface card corresponding to slot 0 of node A0.
Maintaining a persistent connection between host and storage, ESXi must support multipathing. Please check out Incorrect description multipathing for VMware vSphere 5.5
AIn addition to path failover, multipathing also provides load balancing. Load balancing is the process of distributing I / O load across multiple physical paths.
BIn the event of a path failover, the virtual machine I / O delays Nintendo pump by 60s.
CIf the failover takes a long time to complete, the windows virtual machine may interrupt the I / O and eventually fail. To avoid this problem barrier, please set windows virtual machine according to the timeout to at least 30 seconds.
DWhen coordinating vmware NMP and any third-party MPP installed, the PSA (Pluggable Storage Architecture) performs load and unload multipathing plug-ins;
Which of the following copy is supported by OceanStor V3 remote file system?

On the Windows Server 2008 R2 system hard disk partition to set a reasonable sector (cluster) size is correct:
ACreate a 2TB NTFS volume, the default sector (cluster) size is 8KB.
BCreate a 30GB FAT32 volume, the default sector (cluster) size is 8KB.
CNTFS volumes can be set to the largest sector (cluster) to 512KB.
DThe smallest sector (cluster) that an NTFS volume can set is 4KB.

AWhen configuring the backup client on the VTL side, you need to know that the WWPN of the FC port that connects the VTL to the VTL is available on the server in the sys /class / fc_host directory and subdirectory to the corresponding WWPN port.
BServer-side identification has been detected with the library device command is cat / proc / scsi / scsi.
CAs shown in the figure, among the devices identified on the server side, the device labeled 1 is the scanned library.
DAs shown in the figure, of the devices identified on the server side, the device labeled 2 is the information for the scanned tape.
