Reading Time: 3 minutesOne year ago, VMware has started the bifurcation of VMware Tools for Legacy and Current Guests using of two separate delivery vehicles: VMware Tools 10.1 is available for OEM-supported guest OSs only VMware Tools 10.0.12 was for the guests OS that have fallen out of support by their respective vendors are offered “frozen”.

Reading Time: 3 minutesIn the VMware ESXi 6.x partitions layout, usually, there is a partition called “scratch” that hosts the log, the updates, and other temporal files. Scratch space is configured automatically during installation or first boot of an ESXi host and is not required to be manually configured. If you install ESXi on a local hardware disk (or also if you are using a remote LUN in “boot from SAN” mode), this partition is built during the installation phase (it’s 4 GB Fat16 partition created on the target device during installation, if there is sufficient space).

Reading Time: 2 minutesOne of the best virtualization related book of 2017, in my opinion, is the VMware vSphere 6.5 Host Resources Deep Dive written by Frank Denneman and Niels Hagoort. It’s main target is for administrators, architects, consultants, aspiring VCDX-es and people eager to learn more about the elements that control the behavior of CPU, memory, storage and network resources. But the most valuable part, is that is not only update to vSphere 6.5, but also with new technologies, like new Xeon family, new type of disks, NVMe, …
Reading Time: 3 minutesSeems that there are still some issues with vSphere 6.5, with a possible PSOD (Purple Screen Of the Death) after upgrade to 6.5U1 on ESXi hosts using 10 Gbps NICs. The VMware KB 2151749 describe this issue and explains that this occurs because Netqueue commit phase abruptly stop due to the failure of hardware activation of a Rx queue. As a result, Internal data-structure of the Netqueue layer’s could go out of sync with the device and cause PSOD.
Reading Time: 3 minutesVMware vSAN 6.6 works only in unicast mode, if you have upgrade all the disks to the last v5 format. But recently I’ve got a new cluster, build totally from scratch with latest version, that has switched to multicast mode, with the result of all hosts partitioned at network level.
