Which one of the following options incorrectly describes the Huawei Oceanstor 9000 file pool strategy?

Nodes can be classified as required, and the load balancing system for each partition supports the configuration of independent load strategies and independent access domains. First name

create strategy is used to determine the initial placement location of the file when creating a file system file. The conditions of this type of strategy include storage path, file File name, UID/GID

Nodes can be classified as required, and the load balancing system for each partition supports the configuration of independent load strategies and independent access domains. First name

Load balancing strategy can be based on: CPU, memory, bandwidth, number of network connections, node capacity value

Oceanstor 9000's load balancing service support; round robin

What is wrong about the AK/SK authentication process among the following options:

After single-selecting OceanStor9000 to retrieve SK, use the MD5 algorithm to request the content of Zhang He Encrypt and generate a signature.

When the user initiates a data request, the SK and the requested content are encrypted using the IAC algorithm, and a signature is generated name.

After OceanStor9000 receives the request and signature, it will check SK according to AK.

OceanStor9000 will compare the received signature with the signature calculated by the corresponding system.If yes, the authentication is passed.Formula, CPU used, number of node connections

Single choice In Oceanstor 9000, what is the wrong understanding of WushanFS global cache technology?

The data in the cache of a node cannot be hit by the read and write services of other nodes

Global Cache in wushanFS will all storage servers

The data in the cache of a node cannot be hit by the read and write services of other nodes

Global cache technology helps to improve node memory resource sharing
