Testing SFS Turbo Performance
Fio is an open-source I/O tester. You can use fio to test the throughput and IOPS of SFS Turbo file systems.
Prerequisites
Fio has been installed on the ECS. It can be downloaded from the official website or from GitHub.
Note and Description
The test performance depends on the network bandwidth between the client and server, as well as the capacity of the file system.
Installing fio
The following uses a Linux CentOS system as an example:
File System Performance Data
The performance metrics of SFS Turbo file systems include IOPS and throughput. For details, see Table 1.

Formula used to calculate the IOPS |
IOPS = Min. [5,000, (1,200 + 6 x Capacity)] Capacity unit: GB |
IOPS = Min. [20,000, (1,500 + 20 x Capacity)] Capacity unit: GB |
IOPS = Min. (1,000,000, 6,000 x Capacity) Capacity unit: TB |
IOPS = Min. (1,000,000, 12,500 x Capacity) Capacity unit: TB |
Common Test Configuration Example
The following estimated values are obtained from the test on a single ECS. You are advised to use multiple ECSs to test the performance of SFS.
In the following examples, SFS Turbo Performance and ECSs with the following specifications are used for illustration.
