Question # 17

In the Huawei OceanStor system, the size of the file system block is a measure of the size of the accessed file system block. The size of the block is designed according to the size of the data block. Different size of the file system block selects the corresponding file system block, according to the size of the data block. If the business scenario is themedia, for large file archiving or stagger I / O backup scenarios, it is recommended to choose the default 64KB disk block size.

Question # 18

OceanStor V3 storage resources are mapped to the bare devices on the host. The host creates a dedicated file system on the host. The testtool is used in the file system. The system produces a large number of 13KB size files, you randomly read these files to test the response time. Changing the prefetch length of 16KB can improve system performance in this case.

Question # 19

Hot-plugging refers toreplacing, adding, upgrading, and removing hardware devices without shutting down the system or power supply. Hot plugging of PCIE is a kind of "no surprise" strategy, that is, when the user unplugs the interface card, you must first notify the system.

True

Question # 20

Customer business is veryimportant and has a large amount of data, requiring the best possible business continuity after natural disasters. Which kind of network design is best for this?

In the same city set up two data centers to do synchronous replication, located in another remote data center to do asynchronous remote replication

Set up two data centers in the same city to form a dual disaster recovery network

Set up a data center in the local and remote sites to form a dual-active disaster recovery network

In thesame city set up two data centers to do double live in another remote data center to do asynchronous remote replication

Question # 22

The peak write bandwidth for an application is 10MB / S, with an average write latency of 200KB / s and anaverage write IO size of 4KB (bandwidth utilization of 70%).

If you need to use OceanStor V3 storage array to implement data disaster recovery and set it as asynchronous replication mode, you need the minimum network-wide bandwidth of which of the following?

3.2Mbps

128Mbps

114 Mbps

18 Mbps

Question # 23

In two OceanStor unified storage arrays configured with remote replication, the optimal path for remote replication data transmission is:

Host - "Linking Primary Array Controller -" Linking From Array Controller -> (Forwarding) Controller operatingfrom a LUN

Host - "Primary LUN Controller -" (Forwarding) Primary Device Controller for Linking - "Link from the array controller

Host - Primary LUN Controller -> (Forwarding) Link Primary Fabric Controller - "Linking From Array Controller-"Hair) from LUn work controller

Host - "Link-connected Primary Array Controller -" Link-connected slave array
