Reading Time: 3 minutes VMware vSphere upgrade process is usually an easy process to execute, due to the vSphere Update Manager simplicity, but it requires a careful planning and attention on the different compatibility and interoperability matrix. An important note is about the different build versions (or the Update releases) of the different components.

Reading Time: 2 minutes One of the new feature of VMware vSphere 6.7 is the full support for Trusted Platform Module (TPM) 2.0 devices both at host and VM level. But when you are using a TPM 2.0 device on an ESXi host, the host might fail to pass the attestation phase.

Reading Time: 2 minutes During holidays, reading some books could be a pleasure but also a moment of growth and deepening. And if you want to learn more on VMware vSphere 6.7 which book could be used?

Reading Time: 3 minutes The Dell Boot Optimized Storage Solution (BOSS) is a new option for the installation of the hypervisor part, in a virtualization enviroment, or more important in a hyper-converged infrastructure (HCI) host! The dual SD option was already present in all PowerEdge, also in previous generations, and was a good choice to separate the hypervisor from the disks or simple use diskless based solutions. And was a good option for vSphere ESXi when servers were only used as a compute nodes.

Reading Time: 3 minutes The last week I’ve realized an article for the StarWind blog and focused on the design and architecture of VMware vCenter and PSC topologies (see VMware vCenter and PSC topologies). Some days ago, there was an interesting post from Emad Younis, on how the external PSC deployment it’s not only an old approach, but will also become no more supported in future release of vSphere (see: External Platform Services Controller, A Thing of the Past).

Reading Time: 1 minute This is an article realized for StarWind blog and focused on the design and architecture of VMware vCenter and PSC topologies. See the original post. You can “federate” multiple vCenter Server systems using vCenter Linked Mode (introduced in vSphere 4.0) to build a single pane of glass and share information between vCenter instances, like view and manage the inventories of all the vCenter Server systems that are linked.

Reading Time: 3 minutes Now that VMware vSphere 6.7 Update 1 was released in GA the “missing piece” was still the Platinum bundle. But now also VMware vSphere Platinum is finally in General Availability (GA). Announced during the VMworld US 2018, VMware vSphere Platinum is an new edition and a new bundle. The new vSphere Platinum is basically VMware vSphere 6.7 Update 1 Enterprise Plus with the addition of VMware AppDefense. Funny but there is no info about the announce credits on VMware Cloud on AWS (Credits worth $10,000 for VMware Cloud on AWS) that now are no more mentioned.

Reading Time: 3 minutes The new release VMware vSphere 6.7U1 has a lot of improvements, but one has not been emphasized too much: VMware vSphere 6.7 Update 1 finally supports Microsoft Active Directory 2016 schema and relative functional level! Lot of people forget that  vCenter Server, vCenter Single Sign-On and the VMware Platform Services Controller have their own interoperability matrix with Active Directory versions based on the Active Directory Domain Services (AD DS) domain functional level, not only with the Windows Server operating system on which Active Directory is running.

Reading Time: 2 minutes Seams that the new VMware vSphere 6.7 Update 1 will break all the Veeam Backup & Replication backup jobs! As reported in the Veeam KB 2443, VMware 6.7 Update 1 is actually NOT supported by Veeam B&R and will be supported only with Veeam Backup & Replication 9.5 Update 4. More information are available on Veeam KB 2784 and this forum thread.

Reading Time: 2 minutes After some months from the announce, finally VMware vSphere 6.7 Update 1 is now generally available (GA) and you can now download all the bits. Of course, this also mean a new version of the VMware vSAN 6.7 Update 1. But more importantly it means also a fully featured vSphere Client with the new version of the HTML5 client in vSphere 6.7 Update 1! There is a bunch of videos available on YouTube with all the HTML5 client features. But before read more, note that actually Veeam Backup and Replication does not support vSphere 6.7 […]

Reading Time: 3 minutes In the last Veeam Community Forums Digest, there are some interesting notes about some possible issues with vSphere Storage vMotion, that usually is used to move backup your VMs in the original datastore during a Instant VM Recovery (IR). Seems that there is major bug in Storage VMotion functionality of vSphere 6.7 when you are using the optional IR feature that allows you to redirect virtual disk updates to the selected datastore.

Reading Time: 4 minutes If you are running VMware vSphere 5.5 or 6.x you may have some issues with VM snapshots with the risk that VMs may report guest data inconsistencies! Not funny at all and potentially a critical problem that must be planned, considering that VM snapshots are used by all VM native backup products! And more serious that the cosmetic snapshot “issue” in VMware vSphere 6.0 using the vSphere C# Client. This issue is still open for vSphere 5.5 (and probably will remain un-fixed considerind that v5.5 is in End of General Support), 6.0 and 6.5.
