[Powershell] vCPU to Physical Core for XenApp VM
For our Citrix XenApp environment that runs on ESXi, we tend to keep a 1:1 ratio when it comes to physical cores and vCPUs. In other words, an ESXi host with 12 cores, will only be running 6 XenApp VMs with 2 cores or 3 XenApp VMs with 4 cores or any other combination, just as long as the vCPUs configured on the VM, never exceed the number of physical cores present in the host. What about Hyperthreading? The extra HyperThreads that a physical CPU offers are not used in the core to vCPU ratio because specifically in a Citrix XenApp workload, they don't offer a guaranteed performance boost. HyperThreading will be enabled in the BIOS though because it doesn't hurt the performance. … [Continue Reading]

Time to switch your vCenter attributes to tags
VMware has been clear about it, you should switch to the vSphere Web Client and stop using the good old Windows vSphere Client. Being best kid in the class, I of course tell my customers to start using the vSphere Web Client when possible and I work with it myself most of the time. During an upgrade to vSphere 5.5 the customer's admin suddenly asked me where he could find the attributes in the vSphere Web Client. To my surprise, the vCenter Server attribute fields are not available in the vSphere Web Client. I did know that VMware now offers tags and categories for a lot of objects in vCenter and we should use these in favour of vCenter Attributes, but I wasn’t aware that the vSphere Web Client no longer shows the attribute fields. Vice versa, the tags and categories only work in the vSphere Web Client and not in the Windows vSphere Client. What exactly are tags and categories? According to the information in the vSphere Web Client: “Tags are a new feature of this vSphere release. Their purpose is to allow you to add metadata to objects. Tags allow you to bring information about your virtual infrastructure form outside vSphere and attach it to objects inside so that actions and decisions can be taken on the basis of that information. In order to avoid conflicts between the many possible uses of tags, tags are organized into categories.”. When looking at tags and categories you can best see them like this: vCenter attribute “name” is now called a category and you can set a category to be tagged only once or multiple times per object. For example the “Datacenter”. The value of an attribute is what is now called the name, for example “Open Line”. How to use tags and categories Tags can be assigned to the following objects: Cluster Datacenter Datastore Datastore Cluster Distributed Port Group Distributed Switch Folder Host Network Resource Pool vApp vCO Scheduled Workflow vCO Workflow Virtual Machine To … [Continue Reading]

Did you know, no VMotion when HA network partitioned

At first I was surprised but after some searching I learned the reasons behind it and it makes complete … [Read More...]
