The maxMBpS option determines the maximum amount of I/O in Mb that can be submitted by GPFS per second.
If the default value is not adjusted accordingly it will affect GPFS performance.
Setting this number too high can have an adverse effect on performance of the system since
overrunning the capabilities of the I/O bus or network adapter tends to drastically degrade throughput.
This number is normally set after empirical study to determine your nodes I/O bandwidth limits.
The default value is 150 MB/s. To change maxMBpS to 300 MB/s:
# mmchconfig maxMBpS=300 |
