When installed to a cluster, the application’s performance and stability depends on the hard drive’s speed. A slow hard drive increases the request latency in the cluster and can cause it to become unstable. We suggest that you use the fio tool to test the hard drive’s speed.
Install and run fio to test your hard drive:
apt install fio
mkdir test-data
fio --rw=write --ioengine=sync --fdatasync=1 --directory=test-data --size=100m --bs=2300 --name=mytest
In the fdatasync data section, we need to check the value of the 99.00th percentile. For the storage to be fast enough, the 99.00th percentile must be is less than 10 ms. For example, if the value is 2000, the latency is 2 ms.
Please note that the minimal IOPS of an entry must comply with the system requirements:
- System requirements for BRIX On-Premises Standard.
- System requirements for BRIX On-Premises Enterprise.
