WMworld Europe 2017 hasn’t officially started yet, but Sunday afternoon the registration booth is already open and it’s a smart idea to collect your badge in this relaxed atmosphere before the Monday-rush.
It’s a lovely sunny day with mild temperatures.

VMware vSphere offers the ability to divide cluster resources into pools. There have been a lot of outstanding articles about resources. I want to emphasize especially the books written by Duncan Epping, Niels Hagoort and Frank Denneman.
Resource pools are a constant source of misconfiguration. Almost every cluster I see in the wild has some no-go’s configured. The most common reason is that RP are misunderstood as folders to organize VMs.
People keep thinking that if they leave all pools at “Normal” it wouldn’t be a problem. In fact it is a problem. Especially if the customer tried to organize his VMs into hierarchical structures, resource pools can become very complicated to track and might do nasty things in times of contention.

In the old days of virtualization a vCenter used to be a nice-to-have commodity. But these times are long gone (at least from an IT point of view). In today’s datacenter many services and applications rely heavily on vCenter. Some of the most common use-cases are VDI-environments, cluster balancing mechanisms like DRS or Storage-DRS and even backup software needs vCenter.
The last one is a crucial point. It’s good to have your vCenter Server Appliance (VCSA) backed up regularly and most of you and your customers will likely do so. But think of what would happen if you’d loose your vCenter for like 10 minutes or even an hour.
It’s not just important to have a backup of it – you also need to return to operation fast and minimize your Recovery-Time-Objective (RTO). Continue reading “Why you should replicate your vCenter Appliance”
