The VMware vSphere 6.7 Clustering Deep Dive is the long-awaited follow-up to best seller vSphere 5.1 Clustering Deep Dive and zooms in on the critical components of every VMware based infrastructure.

It provides the knowledge and expertise needed to create a cloud infrastructure based on the solid foundation of vSphere HA, vSphere DRS, vSphere Storage DRS, Storage I/O Control and Network I/O Control. It explains the concepts and mechanisms behind these features that enables you to make well-educated decisions.

This book takes you into the trenches of HA, DRS, Storage DRS, SIOC and NIOC and gives you the tools to understand and implement, e.g., HA admission control policies, DRS resource pools, Datastore Clusters, network resource pools, and resource allocation settings.

Each section contains basic design principles that can be used for designing, implementing or improving VMware infrastructures. Combine this book with the vSphere 6.5 Host Resources Deep Dive book, and you have an in-depth and comprehensive set of books that deliver the information you need to design and administer vSphere in the enterprise.

Often referred to in the virtual community as the vSphere Resource kit, the Host Resource Deep Dive zooms in on hardware resources such as CPU and Memory and covers how the vSphere 6.5 resource scheduler manages these. The Clustering Deep Dive builds on top of that and zooms in how a group of ESXi hosts work together and provide clustering services.

Google did it again with Chrome browser, version 69. If you use Chrome to access your web client, you notice that you are prompted to select Get Adobe Flash Player.

I didn’t know is that Google switched off the support for Flash Player, you aren’t able anymore to add websites to the allow or deny list in the Flash settings within the browser. Or at least you can’t add the websites directly on that list in the settings. There are some more clicks to do.

Officially announced was the end of Flash Player by Adobe. By the year 2020 Flash Player won’t exist anymore, won’t be supported neither by Adobe nor by the most used browser software. But there’s a “but”. You can manually add specific websites to the allow or block list of Google Chrome, but not in the way you might knew.

Most websites are already HTML5 compatible and all stuff works without that crappy Flash plugin! Do you use the VMware vCenter browser client? Probably the Flex Client because you still have the need for it, like vSAN, Update Manager, or 3rd party plugins of different software and hardware vendors within vCenter? The vCenter Flex Client (aka Flash client) obviously won’t work anymore without Flash.

"This is the temporary fix for now until the next Google Update"
1. Open Google Chrome and enter “chrome://flags/#enable-ephemeral-flash-permission” into the address bar
2. Change it to “Disabled“
3. Click the “Relaunch Now” button
4. Now enter “chrome://settings/content/flash?search=flash” and you should see the list of websites which was “gone” before disabling ephemeral Flash permissions.
5. Add the website to the list
