VMware vSphere APIs for I/O Filtering (VAIO) – how does it work?

VMware has recently released VMware vSphere APIs for I/O Filtering (VAIO), a handy document that highlights the VAIO I/O Filtering technology operational principles. Here, we shed light on them briefly and discuss how VAIO can be implemented in a production environment. VAIO is a technology and an API providing the direct access to the virtual machines’ guest OS I/O Stream.

Setting statistics collection levels for the VMware vCenter Server and estimating the size of its database

Very often, VMware vSphere administrators have to find the reasons of performance issues by analyzing the historical data of various metrics on the VMware vCenter Server. However, sometimes the default set of metrics is not enough if you view performance data for the previous night or the end of the past week – in this case, you need to change the level of collected metrics and, possibly, the frequency of their collection and retention. In the VMware vCenter Server settings, you can set the data collection levels, different collection intervals and the time period that the data will be stored on the Server. In addition, you can set an approximate size of the virtual infrastructure in the host servers and virtual machines, which will allow to roughly estimate the size of the vCenter database. Let’s take a closer look at these settings.
