With virtualized environments performance issues can be hard to pinpoint. IT departments can find it difficult to spot whether the cause is in the application, network, storage, or virtualization layer of the infrastructure. Software optimization specialist SIOS is bringing machine learning to bear on this problem with the latest release of SIOS iQ, its analytics software for VM environments. For the first time, IT staff can easily identify and resolve the root causes of performance issues based on analysis of both the VMware infrastructure and the SQL Server application environment. Other advances enable users to accurately predict and forecast performance and capacity utilization, improve efficiency by identifying and resizing under- and over-provisioned VMs, and save datastore capacity by instantly identifying rogue disk files (VMDKs).
