Having the appropriate access levels assigned to each user or group helps mitigate the security concerns as well as lowers the risk of human error. You certainly don’t want people other than VMware admins to mess with hosts, clusters, virtual switches or the storage. There are some predefined Roles which… Continue reading

Day-to-day troubleshooting What is the link between datastore extension and root password? Last week, I was asked for help: a junior VMware administrator, fresh VCP certified, was facing issues with extending a datastore.

Now, this is not a problem at all in most cases, but sometimes it can create problems. For example imagine a situation… Continue reading

I’m in the middle of the project where I need to split up my environment into two vCenters so I decided to update part of it to vSphere 6.0 to ease up my work and operations tasks later on. I do have a stretched infrastructure across the datacenters including storage… Continue reading
Possibility of cross vCenter vMotion is quite popular among customers. But the thing is that most of the times the vCenters, or the environments managed by those vCenters, are in different sites or locations. This simply means they do not share same vMotion network. Which means vMotion traffic needs to… Continue reading
