VMware vSAN 6.7 Update 1 was presented during VMware VMworld 2018 and became available for download recently. It is still talked over in the IT community as the update brought many new features to the platform. TRIM/UNMAP, the process for guest OS disk space reclamation, is one of those new features. To make the long story short, it enables to use the storage resources smarter once you create thin provisioned virtual disks. In this article, I discuss how to enable TRIM/UNMAP and why actually you need this feature.

VMware introduced REST API in VMware Fusion 10, the desktop virtualization platform for MacOS, back in the last fall. This interface enables to orchestrate not only the virtualization platform itself but also virtual machines running on top of it. Exact the same REST API appeared in the recently released VMware Workstation 2018 Tech Preview. However, there’s a small thing about the API for Workstation: it works only on Windows hosts so far.

For some reason, VMware Skyline is not common knowledge for VMware vSphere admins and VMware products users on the whole. Skyline is VMware proactive support technology allowing to provide advanced technical support for VMware vSphere products (including vSAN 6.6 and later) and VMware NSX. Soon, some other products will be supported. But wait, what is this service actually for? To make that thing clear for everyone, I’d like to shed light on VMware Skyline in this article.

One day, any VMware administrator may require the so-called “support bundle” which contains log-files, diagnostic information, and performance metrics. Taken together, these parameters allow troubleshooting VMware vSphere. The bundle provides VMware GSS (Global Support Services) the insight into virtualized environment configuration which allows them to resolve issues, when a client submits a support ticket with this bundle attached.

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. VAIO is already employed in partner products for maintaining various tasks (i.e., caching write-back and write-through). VAIO is based on the Storage Policy Based Management framework, dedicated to managing virtual machines storages and set the storage rules.
