CIFS transfer block size refers to the size of CIFS file sharing in a single service request between the IP client and Oceanstor 9000.

The size of the data block

Analyze the file size ratio that needs to be stored in Oceanstor 9000 to obtain the storage file model, and then select an appropriate size Numerical value

To adjust the transmission block size, you need to adjust the client and Oceanstor9000 at the same time. Small value shall prevail

Since the parameter value in Oceanstor 9000 has been set to the minimum value by default, it is only necessary to adjust the parameter value of the client to the target value.

InfiniBand technology has the advantages of high bandwidth, low latency, and good system scalability

InfiniBand technology is often applied to the connection between the server and the server

InfiniBand technology will be widely promoted in Internet network connection

Switch is the basic component in InfiniBand structure

Check the zone configuration

Check all events

Export system data

Check the warning information

Not feasible, 200Mbit/s is required to calculate the bandwidth.

Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the bandwidth utilization rate must be >80%.

Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the write I/O size must be less than 2KB.

Feasible, because the conditions meet the requirements of the primary and standby synchronous remote replication disaster recovery program.

It can ensure the system's response speed to hot data access and improve the storage performance of the entire system.

Comprehensively utilize the cost advantages of different storage media to effectively reduce deployment and maintenance costs.

Improve system storage performance and realize intelligent data management.

Realize automatic file migration according to the corresponding relationship between file attributes and different storage devices, reducing the cost and complexity of manual management.
