Reading Time: 3 minutes One interesting news of the latest version of vCSA is the health monitoring feature. You can check the overlall health with your vSphere Client, by selecting the vCenter node and then Monitor | Health.

Reading Time: < 1 minute Universal Serial Bus (USB) is an industry-standard that establishes specifications for cables and connectors and protocols for connection, communication, also and power supply between computers, peripheral devices and other computers. How USB is supported in VMware vSphere?

Reading Time: 2 minutes Changed Block Tracking (CBT) is a VMware feature introduced in vSphere 4.0 in order to implement native incremental backup at source level. VMware VDAP uses this technology and so all backup and recovery software designed for VMware use it for speed the backup. This mean that all the backup products that are using VDAP, will rely on VMware API and features, … and bugs.

Reading Time: 5 minutes VMware vSAN 6.7U3 it’s out and maybe you would like to upgrade your environment. But note that there are some possible performance issue with vSphere 6.7U3 on Dell servers. In my opinion, one reason to upgrade is to finally have the automatical proactive rebalancing feature. You can automate all rebalancing activities with cluster-wide configuration and threshold settings. Prior to this release, proactive rebalancing was manually initiated after being alerted by vSAN health checks.

Reading Time: 4 minutes Last week, VMware has announced the future release of VMware vSphere 6.7 Update 3, that means, of course, also the new vSAN 6.7 Update 3 (vSAN is totally integrated in vSphere code). Unfortunately, has happened in past, this is just a product announce, without provide the code of it and the date of General Availability (GA) release date (but I guess will be on VMworld US 2019). I usually prefer talk about what exist now and see the release notes. The products are now GA and, most important the hardware compatibility and the software interoperability matrix have […]

Reading Time: 3 minutes Six month ago there were only few VMware vSphere 6.7 books, but fortunately now there is a better offer with also some good and valuable resources. I’ve already wrote about the new edition of Mastering VMware vSphere 6.7, now I would like to write some comments about the VMware vSphere 6.7 Data Center Design Cookbook – Third Edition book released on March 2019 and written by Mike Brown and Hersey Cartwright.

Reading Time: 6 minutes The new VMware vSphere 6.7 Update 2 has been announced some weeks ago, but was not yet available (although lot of people have already wrote about most of its features)… now finally VMware vSphere 6.7 Update 2 is general available (GA) and you can download the bits and really test all its features This is a huge step and called just an update release is too limiting… there are so much difference with the VMware vSphere 6.7 Update 1 (released on October 2018) to make it much more like as a 6.8 version.

Reading Time: 3 minutes VMware vSphere Update Manager (VUM) enables centralized, automated patch and version management for VMware vSphere and offers support for VMware ESXi hosts, virtual machines, and virtual appliances. For ESXi hosts it can manage both the update and the upgrade workflows, but can also be powerful for adding custom VIB package, like for example new drivers. Usually it takes the updated files from the VMware repository, but you can also add custom repositories (or depots).

Reading Time: 6 minutes I’ve already wrote about the different reasons on Why upgrade to VMware vSphere 6.7 (or why not), but I’ve not yet provide tips and hints on how perform the upgrade process. If you are lucky enough to have a full VMware Cloud Foundation (VCF) stack, then you don’t have much problem… the VCF Lifecycle Manager that can make your life easier (see also Simplify VMware’s products update/upgrade). Otherwise you need to plan this activity carefully and perform different tasks, some manual, some automatic.

Reading Time: 2 minutes Packt has released a new book for VMware vSphere: Mastering VMware vSphere 6.7 – Second Edition written by Martin Gavanda. I’m in the author list, but just because some of the material of this book cames from the Mastering VMware vSphere 6.5 book.

Reading Time: 3 minutes VMware vSphere upgrade process is usually an easy process to execute, due to the vSphere Update Manager simplicity, but it requires a careful planning and attention on the different compatibility and interoperability matrix. An important note is about the different build versions (or the Update releases) of the different components.

Reading Time: 2 minutes One of the new feature of VMware vSphere 6.7 is the full support for Trusted Platform Module (TPM) 2.0 devices both at host and VM level. But when you are using a TPM 2.0 device on an ESXi host, the host might fail to pass the attestation phase.
