Nutanix: Metro Availability & vSphere 6

During some tests with metro availability in the lab with NOS 4.5 and vSphere 6 I noticed that it was not possible to pair the two Nutanix clusters as usual. After the remote site was configured on both clusters, it was not possible to configure metro availability due to the reason that no compatible remote […]

Nutanix: vmnic down warnings after vSphere 6.0 upgrade

After we upgraded our Nutanix clusters some days back from vSphere 5.5 to vSphere 6.0 we got a massive amount of ongoing warnings, which claimed that two vmnics on each node were down (“Link on NIC vmnicX of host xx.xx.xx.xx is down”). In general that was correct because the vmnics were down…….but they have been […]

Nutanix: Unable to delete container / VDisk(s) not marked for removal

If you are unable to delete a container within Prism this is mostly related to remaining files on the datastore / container. When you try to delete the container you will get an error message like “Container {container-name} contains VDisk(s) 123, 456, 789 not marked for removal.” Mostly it should help if you remount the […]

Lab results: Benchmarking a Nutanix Block

The last weekend I spend some time in our solutions center at work to play around with a Nutanix block. I thought it would be interesting to benchmark the system to see how much performance you can get out of it and would like to share the results with you in this post. Hardware & […]

VMware vSphere 6: Hidden C# client enhancement

I have seen multiple vSphere environments in the last couple of months, which had a lower EVC baseline as necessary configured with vSphere 5.5. The reason in these cases always was that the customer used the vSphere C #client for all kind of configurations. If you have an Intel Ivy Bridge CPU in your ESXi […]

Troubleshooting Veeam B&R plugin for vSphere Web Client

Recently one of my customers had problems to get the Veeam Backup & Replication Plugin working for the vSphere Web Client. The Veeam Enterprise Manager (v7) was configured correctly and showed, that the vCenter Server was registered and the plugin installed. Still the plugin did not show up in the web client. The customer already […]

VMware vCenter Orchestrator (vCO) installation ‘gotchas’

I needed a portable vCO lab environment, so I quickly installed the vCenter Server appliance, a ESXi host and the vCO appliance (5.5.2) on top of my notebook with VMware workstation. For different reasons (mostly releated to my small lab setup) I had a bunch of problems during the setup of the vCO appliance, which […]

Trendmicro Deep Security: Filterdriver for vSphere 5.5 Update Manager

It seems that Trendmicro has no updated package of the filterdrivers for Deep Security with vShield Endpoint for vSphere 5.5. At least the zip package you can download from the official site is for vSphere 5.0. The VIB file which is contained within this package works fine with 5.5 and is also supported according to […]

vCNS: Empty Summary Page

I recently performed an vSphere Upgrade to 5.5 including vShield Manager / vCNS. Before I started with the vShield Manager Upgrade I wanted to check the status of the Endpoint service on the ESXi Hosts. If you select a host within vShield Manager and navigate to the summary tab you normally see the status of […]
