Optimizing performance by aligning the I/O of misaligned virtual machines non-disruptively

Virtual Storage Console for VMware vSphere can scan your datastores to determine the alignment status of virtual machines. You can then use VSC to functionally align the I/O to certain misaligned virtual machines without having to power them down.

About this task

Online alignment is a good choice for virtual machines that you cannot take offline. When possible, you should take the virtual machine offline and physically align the VMDK using a tool such as VMware vCenter Converter.
