20 February 2018
Comments off

Reading Time: 3 minutesI’m very proud and honored to be invited again to the next Tech Field Day in Austin (TX). It will be the 16th edition of Tech Field Day (#TFD16), just one year after the 13th, still in Austin (and where I was also invited).

Resize a Linux filesystem without LVM

Reading Time: 3 minutesIncrease a virtual machine disk size it’s so easy, on almost all hypervisor: just click and increase the space on the virtual disk.

For Windows OSes, starting with 2008 (Windows Server 2008 and Vista) it’s quite easy and totally manageable from the GUI (with the Disk Manager MMC). For Linux, it could be easy with LVM, but […]

PSOD on vSphere 6.5 and 10 Gbps NICs: solved!

27 December 2017
Comments off

Reading Time: 2 minutesOn October 2017, I wrote a post about a possible issue with vSphere 6.5 and 10 Gbps NICs (mostly standard on new deployment). The final result was a PSOD (Purple Screen Of the Death) and no solution was available (yet). VMware KB 2151749 describe this issue as related to possible upgrade at vSphere 6.5. But other customers have report the issue also on new deployment.

Comments off

Reading Time: 5 minutesAs written in a previous post, some months ago, I’ve started a huge personal project that consumes all my spare free time. This project was a new book on VMware vSphere 6.5, really ambitious considering that will be a “Mastering” book, but the title and part of the content were not negotiable with the editor. Finally, the book Mastering VMware vSphere 6.5 is done and it’s now available on Packt site (and in the future also on Amazon).

12 December 2017
3 comments

Reading Time: 17 minutesThis is an article realized for StarWind blog and focused on the design and implementation of a stretched cluster. A stretched cluster, sometimes called metro-cluster, is a deployment model in which two or more host servers are part of the same logical cluster but are located in separate geographical locations, usually two sites. In order to be in the same cluster, the shared storage must be reachable in both sites. Stretched cluster, usually, are used and provided high availability (HA) and load balancing features and capabilities and build active-active sites.
