Client options for VMware vSphere

25 August 2017
Comments off

Reading Time: 3 minutes Finally has been announced (or better, confirmed) that VMware plans to deprecate the Flash-based vSphere Web Client with the next numbered release (not update release) of VMware vSphere. What does it mean, that the HTML5-based vSphere Client will become the only GUI client… finally! After the death of the vSphere Client for Windows, written with C# and with several issues, like the console issues with Windows 10, but also with several inconsistency with the others clients, now it’s the turn of the Flash based client.

ESXi 6.x virtual switch ports configuration

17 August 2017
Comments off

Reading Time: 2 minutes One propertiers of VMware (standard) virtual switches was the number of ports per switch. A parameter (120 was the default in ESXi 5.x) that define how many virtual NIC and/or vmkernel interfaces you can connect to the virtual switch portgroups. This parameter was static and any changes require a host reboot. But starting with vSphere 5.5 (see KB 2064511) this parameter has become “elastic”.

ESXi Networking – Disable IPv6?

4 August 2017
4 comments

Reading Time: 2 minutes Several people are disabling IPv6 support in ESXi for different reasons: because of the minimum privilege principle (if you are not using a service, why you have to keep it enabled?) or simple because they don’t want any IPv6 address in the network. On Linux and Windows systems is become very difficult disable it and Microsoft itself does not recommend disabling IPV6: ” We do not recommend that you disable IPv6 or its components, or some Windows components may not function.” (https://support.microsoft.com/en-us/kb/929852)

Reading Time: 2 minutes VMware vSphere 6.5 Update 1 has been released on July 27, 2017 with several bug fix, some improvements, but also some interesting changing in maximum numbers (for vCenter in linked-mode) and an interesting news for the Foundation edition that now can manage up to 4 nodes (and not only 3 nodes like in the past). Seems a minor improvement, but demostrare how VMware takes care of its customers. In discussions with customers with smaller environments, VMware has received feedback that 3 host environments were too small in many cases, and just another hosts could be enough […]

Reading Time: 2 minutes The new VMware Virtual SAN (or vSAN) 6.6 adds several enchaments and new features as described in the announce notes. Some interesting news are related to security aspects and how data-at-rest could be protected: one option could be new vSphere 6.5 VM encryption format but now it’s also possible use the native vSAN encryption. Duncan’s post explains the difference of those two approaches.

Bye bye 3rd party virtual switches in ESXi

10 April 2017
Comments off

Reading Time: 2 minutes VMware has announced the discontinuation of its third party virtual switch (vSwitch) program, and plans to deprecate the VMware vSphere APIs used by third party switches in the release following vSphere 6.5 Update 1. Subsequent vSphere versions will have the third party vSwitch APIs completely removed and third party vSwitches will no longer work. In the past years, VMware has recommended the Nexus 1000V users to move into the VMware vSphere Distributed Switch to avoid future problems, now it’s clear the product version where you can go.
