Issues with Windows based vCenter

19 August 2018
Comments off

Reading Time: 3 minutesIf you still are using the Windows based vCenter Server with a SQL Server database you may have some login issues, due to a recent Windows update (released on July 10, 2018). You will have some errors in the SQL Server part with SQL startup issues due to “TCP port is already in use” errors. This is caused by a regression in the TCP/IP functions that manages the TCP port pool introduced in the July 10, 2018 Windows updates for Windows 7/Server 2008 R2 and Windows 8.1/Server 2012 R2.

Backup VCSA with VAMI

12 August 2018
Comments off

Reading Time: 3 minutesOne common way to backup the VMware vCenter Server Appliance (VCSA) is to manage as a common VM and use a backup solution to backup (and restore) the entire VM. But it’s approach does not always work, for example in the case of a database corruption the VM restore could be not working. Starting with vSphere 6.5 and the new VCSA 6.5 was possible to use also a native backup solution integrated with the vCenter Server Appliance Management Interface (VAMI). But it was a manual operation (some scripts are available to automate and schedule it).

Reading Time: 7 minutesNote that this post becomes obsolete with the vSphere 6.7 Update 1 release where the client it’s finally complete. Some months ago I’ve written a post (Is the HTML5-based vSphere Client ready to replace the vSphere Web Client?) on the limitation of the new vSphere Client, but this was before the vSphere 6.7 and vSphere 6.5U2 releases. VMware vSphere, during its history and the different versions, has got several types of Graphical User Interface (GUI) client. One of the most used (not the first, but the standard one since Virtual Infrastructure 3.0) was the vSphere […]

Reading Time: 2 minutesVMware vSphere 6.5 it’s quite popolar now, considering the deadline for the version 5.5 in this year and the direct upgrade path from v5.5 to v6.5. But maybe not everybody want to update vSphere 6.5 to Update 2, considering that there will be no upgrade path (yet) to version 6.7 and maybe other minor issues due to the backport of some features.

Why upgrade to VMware vSphere 6.7 (or why not)

8 May 2018

Reading Time: < 1 minuteThis is an article realized for StarWind blog and focused on the pro and cons of an upgrade to vSphere 6.7. See also the original post. Now that VMware vSphere 6.7 has been announced and it’s also available in General Availability (GA), some people may ask if it makes sense upgrade to this version (or when will make sense upgrade to 6.7). Is a GA release ready for a production environment? Or is it mature and stable enough?

Reading Time: 2 minutesVMware has just released the new vSphere 6.7 only a few weeks ago, but now it’s the turn to update the previous version: vSphere 6.5 Update 2 is now available, with some interesting news. New builds will be 8307201 for vCenter and 8294253 for ESXi. The official vSphere documentation is already updated to vSphere 6.5U2 version. All PDFs could be downloaded from this link. The interesting aspect is that vSphere 6.5U2 includes some backported features from vSphere 6.7!

VMware vSphere 6.7 scalability

23 April 2018

Reading Time: 4 minutesThe new VMware vSphere 6.7, recently available in GA, increase all configuration maximums to new limits (compared to the v6.5 and previous versions). Maybe we can say with no limit, or at least, to be serious, with really huge numbers compared to the actual needs and the existing compunting power. Those new limits are both for scalability aspect, but also to fit with possible performance requirements, considering that a bigger number of business critical applications are going in the virtual environment.
