A.Oceanstor9000 supports giant frames, it is necessary to set the MTU of all front-end and back-end business network ports.

B.NFS uses the TCP protocol to send and receive data. Appropriately increasing the buffer area can speed up the TCP transmission speed.

C.In order to support giant frames, all nodes of the corresponding Oceanstor 9000 need to be set accordingly.

D.Enabling giant frames can reduce TCP loss and improve performance. The premise is to confirm that all network devices between the Oceanstor 9000 front-end network interface and the client interface must support giant frames.

A.You can limit the resource usage of a single directory, user, and user group

B.The resource usage can be reminded to resource users through alarms and events

C.The main function of SmartQuota is to facilitate system administrators to manage the storage resources of resource users

D.SmartQuota supports two storage types: block storage and file storage

A.Load balancing layer

B.Active-active storage layer

C.Active-active web and application layers

D.Active-active database layer

E.File system layer

A.In order to ensure uninterrupted business, the online upgrade needs to be upgraded node by node, so the cluster upgrade time is related to the number of nodes in the cluster

B.When a node is upgraded, if other nodes fail, some business data may be inaccessible

C.There are multiple nodes in a cluster. After a node is successfully upgraded, users can use the functions of the new upgraded version

D.Online upgrade can perform upgrade operations on all nodes in the cluster at the same time

A.The unit storage cost of a disk is lower than that of a physical tape.

B.The backup and restoration performance is high.

C.The management and maintenance costs are low.

D.Disks where data is stored can be separated from the device that reads and writes data to these disks, implementing offline storage of data
