VMware vSphere 6.0 has got some issues, like the several related to CBT and data protection, during the first years of its life. Mostly is finally resolved, but you may still have strange issuesespecially during the upgrade procedure (most when you start from a vSphere 5.1 version). I notice, after an upgrade, also a strange behavior with vMotion where live VM migration fails with this error: A general system error occurred: PBM error occurred during PreMigrateCheckCallback: No connection could be made because the target machine actively refused it.

If you plan to build a lab for vSphere 6.0 you can use all the approches for vSphere 5.x (see also Building a vSphere 5 lab): usually using a nested environment (or three physical systems, if you have) as a common platform. Of course, the other way to test new products it’s just use the VMware Hands on Labs that you can also “broke” or use in a different path compared to the one suggested by the guide. But having a local environment permit more flexibility and more time for testing or learning. The big […]

With the new VMware vSphere 6.0 there are a lot of changes, and some of them are in the new vCenter architecture both for the Windows installable version and the virtual appliance (vCSA) version. For this reason the design aspects and the deployment scenarios are changed from the previous version (see VMware vCenter 5.5 design). Windows vCenter installation experience has been enhanced with additional capabilities including custom ports, custom paths, uninstall and error messaging improvements and vCenter Server Appliance (vCSA) now has a guided installer. Furthermore, all upgrade paths from Windows vCenter 5.0 and up […]

In previous versions of vSphere, the vCenter Server was not suitable to provide directly cloud based functions: vCloud Director was the way to build a Software Defined DataCenter (SDDC) at the top of vSphere and provide more functions and concepts that were not available in vCenter. But, during the VMworld 2013, VMware introduced a new product strategy and direction for vCloud Director (vCD): VMware would like to move forward with a plan to converge vCD functionality into the vSphere and vCloud Automation Center (vCAC) product lines or (as another direction) in the virtualization platform (that […]

The new VMware vSphere Suite 6.0 brings several changes and new features, but the installation phases remain still similar with the previous versions. The big changes are in the vCenter deployment type both for the installable and the appliance version and the new VUM client… all the other parts of the installation remain similar  with only few notes.

The design of the VMware vCenter Server and related services has several decision that you have to take, and of course some of them will change with the version number of this products (for example SSO design are different from 5.1 and 5.5). During the last Nordic VMUG User Conference I’ve taken a session about some the design aspects and I want to comment some of the aspects. There are also other references that you can use, like a post of Max Mortillaro (vCenter Server Design Considerations) that can add more information or other point […]

Today I’m attending at the Nordic VMUG User Conference (it must be the second or the third user conference of this group) that represent also my first VMUG User Conference outside Italy. Past year there were 470 attendees (623 registered) really a lot of people and, in fact, the Bella Center is used (the same used in VMworld EU editions in Copenhagen).

My session at vBrownbag Tech Talks will be today: 12:00 – 12:15 “VMware vCSA – Pro and Cons” This is the related materials: Slides Video

Starting from vSphere 5.0, the vCenter Server Virtual Appliance (vCSA) is a new deployment options with some pros and cons. Some of the cons may limit it in the large environments, but starting with the version 5.5 the embedded database has more interesting limits to make it suitable for most of the SMB cases. Honestly I like the idea to have a vCenter Server as a single black box: it make simple to manage and backup it. But also to update (update vCSA is really faster compared to update a tradition vCenter Server). Anyway there […]

Seems that VMware is cleaning its products portfolio. After the End of Availability of VSA, now VMware is announcing the End of Availability (EoA) of all VMware vCenter Server Heartbeat versions effective June 2, 2014. As a result, all versions of vCenter Server Heartbeat will be removed from the VMware price list on June 2, 2014. After this date, you will no longer be able to purchase these products. All support and maintenance for the removed versions will be unaffected and will continue on per VMware Life Cycle policy through the published support period until […]

Formally a VMware vSphere Essential Plus (or Essential) suite can only be managed by a vCenter Server Essential (which is in fact a vCenter Foundation limited to only handle Essential or Essential Plus hosts). The reason is simple: the Essential bundles were born and developed for SMEs as finished packages and not as a way to extend their infrastructure (especially since formally every company could only buy one of these bundles). But until the vSphere 4.x releases was still possible to manage one or more Essential / Essential Plus clusters with a single vCenter Server […]
