I/O control troubleshooting

In vSphere infrastructure storage, I/O usage of virtual machines can be controlled by Storage I/O control (SIOC). SIOC delivers storage I/O performance isolation of virtual machines. You can easily run important workloads using SIOC in virtualized storage infrastructure while it stops heavy I/O used virtual machines from impacting on less I/O used virtual machines. You can also allocate a preferred I/O resource for virtual machines using SIOC during bottlenecks. In addition, SIOC can be used to alleviate the poor performance of critical workloads because of I/O bottlenecks and latency in peak times. Some of the features of SIOC are as follows:

  • SIOC is disabled by default and needs to be enabled for each datastore in ...
