As part of a vSphere 5.5 to vSphere 6 migration effort, we wanted to audit privilege changes for numerous custom roles to see how they would need to be updated in the vSphere 6 environment. I’ll briefly outline the (mostly generic) method I used to do this comparison and also include the results.
Today I logged into my lab after a power outage and noticed that vCenter was not up. I accessed to host directly, and opened to console to the VCSA server. The VCSA server was not able to mount the filesystem, and had this on the screen:
In our previous post you learned how to get started with using PowerCLI against vR Ops and how to use the cmdlets to work with alerts, in this post we take you a step further an learn how to take the work from the previous post and use it with Recommendations and Statistics from vR Ops.
PowerCLI is great tool, and the Team behind it surprises us on a regular basis with a new Release. With the v6.x generation we witnessed the introduction of Modules. And the Team keeps adding further integration with other VMware products.
As many of you might have already known, this is the time for voting for the top vBlogs for the year of 2016. An yearly program by Eric Siebert of vsphere-land to identify the industry’s top bloggers in various categories. This year’s voting is in partnership with VMTurbo .
VMware vSphere is the foundation of the Software-Defined Data Center. The new vSphere 6 extends your ability to virtualize scale-up and scale-out applications, redefine availability, and simplify your virtual data center.

One of the major announcements at EMC World this year was the release of Unity, a new midrange All-flash storage array from EMC. I was particularly pleased to see this release as a key design goal for Unity was to deliver native support for vSphere Virtual Volumes and Storage Policy-Based Management. The certification for EMC Unity for both block and file across both All-flash and Hybrid configurations has been completed and is available on the updated VMware Virtual Volumes compatibility guide.
Workstations are the way work gets done in many industries around the world, such as aerospace, automotive, space exploration, oil and gas. Engineers and designers have traditionally relied on dedicated graphics workstations to perform the most demanding tasks, such as manipulating 3D models and visually analyzing large data sets. Standalone workstations are anchored to brick-and-mortar facilities. These workstations also carried high acquisition and maintenance costs, requiring the user to be present in the lab or office.
So in the previous article we saw the types of backup protocol used by VDP. We saw that when the ESXi host which is hosting the VDP appliance does not have the access to the datastore of the VM it is backing up, then the backup protocol used is Network Block Device (NBD). One way to avoid NBD is to bring the VM on to a storage which is seen by the ESXi host hosting the VDP appliance. The other method is to deploy an external proxy for the VDP appliance onto the host which is hosting the client that needs to be backed up. Please note, that once you deploy external proxy, the internal proxy will be disabled automatically.
Disruptive innovation, is a term coined by Clayton Christensen. The term describes a process by which a product or service takes root initially in simple applications at the bottom of a market and then relentlessly moves up market, eventually displacing established competitors.
It had originally been configured under SRM using v 5.1, and it had been set up to test and never used. This was before my time, so when I arrived I was tasked with an IP migration for the whole vSphere environment (which you can see in my older posts).
A really useful capability that vCenter Server used to provide was a feature called vCenter Maps. I say “used to” because this feature was only available when using the vSphere C# Client and was not available in the vSphere Web Client. vCenter Maps provided a visual representation of your vCenter Server inventory along with the different relationships between your Virtual Machines, Hosts, Networks and Datastores. There were a variety of use cases for this feature but it was especially useful when it came to troubleshooting storage or networking connectivity. An administrator could quickly identify if they had an ESXi host that was not connected to the right datastore for example with just a few clicks.
Recently, a customer reported that DRS was not working to load balance the cluster. Under normal circumstances, a minor imbalance is nothing to be concerned about. This is because the main objective for DRS is not to balance the load perfectly across every host. Rather, DRS monitors the resource demand and works to ensure that every VM is getting the resources entitled. When DRS determines that a better host exists for the VM, it make a recommendation to move that VM.
This will be a series of post covering more advanced vSphere concepts in depth and different design considerations that we need to take care before the implementation. This post will be an introduction to Hardware design considerations that we must oblige too. All the hardware compatibilities are listed in VMware Compatibility Guide Tool which is best source.
