Reading Time: 2 minutes Several months ago VMware announce vSphere APIs for IO Filtering (VAIO) as a solution to implement 3rd Party Software-Defined Data Services in vSphere 6.0. VAIO offers partners the ability to put their technology directly into the IO stream of a VM through a filter that intercepts data before it is committed to disk. It’s a good and efficient idea to implement features like caching or replication without the need of external components (or appliance) or kernel modules like today. But this a partner program (like the Virtual Volumes) and unless partners have not developed this […]

Reading Time: 3 minutes VMware Virtual SAN 6.0 (formally was v2.0) was a big improvement of the VMware’s hyperconverged storage solution with some important new features like the new filesystem (with powerful snapshot implementation), the concept of fault domain (to improve data resiliency), more scalability and the full flash option. Now VMware has announced a new release: Virtual SAN (or VSAN) 6.1, with new improvements, including enhanced usability & management, advanced troubleshooting, and several new features.

Reading Time: 3 minutes VMware snapshots are widely used for different purpose, but the main reason why they exist in vSphere is to help backup programs: using VADP a backup can start a VM snapshot in order to have a frozen file, copy it (or copy only the changed block with CBT and virtual hardware 7 or greater) and then release the snapshot. Other usage are to have a just in point rollback during patches or big changes, but a recommended practice is to release the snapshot as soon as possible. Large snapshots or broken or invalid snapshots are […]

Reading Time: 3 minutes In July 2015 the VMware Workstation team announced the public access to the VMware Workstation Technology Preview 2015 that has now officially becomed VMware Workstation 12. There are a lot of news related to this new version, but one is about the two different editions: Workstation Pro and Workstation Player (formerly known as Player Pro). This split partially match the same on Fusion where there are two different editions.

Reading Time: 4 minutes If you are planning an in-place upgrade of a vCenter Server (the Windows installable version) you have to read carefully the vSphere Upgrade Center resources to avoid possible issues. Of course you can choose to install a new vCenter Server instance a move all to the new one. Maybe could be the right moment to switch to the vCenter Server Appliance (there is also a Flings to move your vCenter Windows data to a VCSA instance). But sometimes it’s not possible and should be preferable an in-place upgrade.

Reading Time: 2 minutes If you have installed (or upgraded to) VMware vSphere 6.0 and you still use the old legacy vSphere client you may have some false positives about VM snapshots. All VMs seems to have some snapshots, also if they don’t (and using consolidate does not fix it, because there aren’t snapshots to be fixed). But this apper only with the Windows vSphere Client:
