Reading Time: 2 minutes The VMware vSphere Host Client (or Host UI) was initially released as a fling in 2015, and then included as the default host client GUI interface with vSphere 6.0 Update 2. A web HTML5 interface was needed in order to replace the legacy Windows’s based vSphere Client. And was a good solution, light and fast enough… But after 10 years it becomes old and the user experience is too much different compared to the vSphere Client (HTML5).

Reading Time: 5 minutes VMware vSphere has a guest customization feature to change some guest OS setting for VMs that are cloned of deployed from template. For example to change the computer name, network settings, or timezone settings. Customizing guest operating systems helps prevent conflicts that occur if virtual machines with identical settings are deployed, for example conflicts due to duplicate computer names. For Linux based VM there are two diffent type of guest OS customization engines: But which one is used and which could be preferred?

Reading Time: 2 minutes The possibility to backup VCSA using VAMI at file level is very powerfull and could be a good “plan-B” in case the backup at image level is not restorable (it happens in case of file/DB corruptions). But, of course, is not perfect and still in latest version there are some issues, like the VAMI backup retention issue. But can also happen that backup fails with no specific errors.

Reading Time: 2 minutes If you are using Veeam Backup & Replication (but also other backup solution) you can perform both backup and replication with the same tool. But with latest version of vSphere you can probably notice a huge difference between backup and replication speed if you are using NBD transport mode.

Reading Time: 3 minutes DellEMC PowerStore is the new product line that will replace the old Equallogic/SC/VNX/Unity series. It’s a nice product with a mix of the features of all those prevuious products and a new modern design both in the hardware and the software parts. From VMware vSphere point of view it can be access as a block level storage with iSCSI and/or FC protocols, but it has also a native vVols implementation and, for example, in the PowerStoreX model it’s the default way to access at the storage resources.

Reading Time: 2 minutes Easy question, but much more complicated answer. If you go to you can found a strange combo of versions:

Reading Time: 2 minutes The file-level backup feature introduced in vCSA 6.5 is very powerfull and schedulable (starting with vCSA 6.7) because sometimes the image-level backup may not provide the proper integrity if you have corrupted files inside the VM. Also with vSphere 7.0 is possible monitoring the status of the file-level backup directly from vSphere Client and this is quite usefull to have this information direct visible from the UI:
