Actually there are two different platform where you can run the vCenter Server components (including the PSC): Windows (both physical or virtual) or Linux (only with the vCSA, based on PhotonOS). Initially there was only a Windows version, then the vCenter Server Appliance (vCSA) was first introduced with the release of vSphere 5.0 and has since evolved to become the definitive deployment model for vCenter Server.

Starting with vSphere 6.5 the vCSA has become the first choice and has raised the level of vCenter with new functionalities (not available on the Windows version).

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.

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”.

One year ago, VMware has started new vExpert (sub)programs on different technologies. One was the vExpert vSAN. I was honored to part of the first list.

Now the list for 2017 vExperts who received the vSAN award has been published.

The program is build upon the vExpert program. To apply you must be a current vExpert as well as evangelizing VMware Virtual SAN. There will be an application once per year for each of the sub-programs.

Also this year the results of the annual contest Voting for the top VMware & virtualization blogs are out on vSphere-land web site, after the usual live show where the top 25 were announced.

This content has become a big reference for all virtualization blogger (it’s not necessary a classification on who is best compared to another), but the top 5-10 are honestly the real top blogger. And it has become a ritual event  in this period of each year (there is also a nice History of the Top vBlog).

In the past, I’ve wrote about Ravello System and it’s unique solution (Smart Labs) that permit self-contained capsules to run your VMware/KVM development, test, training and demo environments in the cloud without migration. Also if the company has been acquired by Oracle (my guess was that most interested in this technology was VMware itself), it remain still active and now more important.

Oracle want to push out the Next Generation of Cloud with the promise to be the Best Cloud for Enterprise and Ravello become an important piece of this vision.

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)

Starting with VMware Horizon 7 it’s possible choose two different way to deliver space optimized desktop pools: using VMware Composer and linked clones technology (existing from several years) or use the new instant clones technology (introduced with vSphere 6.0).

Similar to View Composer linked clones, instant clones share a virtual disk of a parent VM and therefore consume less storage than full VMs. In addition, instant clones share the memory of a parent VM. Instant clones are created using the vmFork technology. An instant-clone desktop pool has the following key characteristics:

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 (of course still for SMB enviroments).  This is why with vSphere 6.5 Update 1 VMware is now increasing the number of hosts that vCenter Server Foundation will support from 3 host to 4.
