Every now and then i receive questions about how the different Organization virtual datacenter (Org vDC) compute (CPU and Memory) settings affects the vSphere layer including the vSphere cluster resource pool backing the Org vDC and the virtual machine (VM). Based on the above i have decided to put together a series of three blog …
A couple of weeks ago i raised a question on twitter if someone had a recommendation regarding a free vSphere monitoring tool. I received quite a lot of answers but not that many fulfilled my customer requirements: Free of charge. Must be able to monitor the virtual machine virtual hard disk utilization e.g. only 10% …
The 1:st of August VMware released the vCenter Server 5.1 U1b. This release does not bring any new features or functions, it focuses on bug fixes. I just wanted to point out one specific bug fix that will justify an upgrade to the newest vCenter Server version for at least one of my customers. vCenter …
Last week i had a discussion with a customer regarding the vSphere Distributed Port Group Teaming and Failover configuration Failback (Failback) when using the Teaming and Failover: Load balancing configuration “Route based on physical NIC load” aka LBT. All available dvUplinks configured as Active uplinks. We discussed if the Failback configuration makes a difference regarding virtual …
During every vSphere design and Health Check the vSphere advanced settings are being discussed and every once in a while i receive an email asking me what vSphere advanced settings i normally use and recommends. I know Duncan Epping wrote a blog post about when to use the vSphere advanced settings a while ago. In general i agree …
I was asked by one customer last week to create a script that adds virtual machines to a vSphere DRS group, “VM DRS Group”, based on virtual machine guest operating. My customer runs vSphere 5.1 and a licensing issue was the underlying cause of the request. My customer have two vSphere clusters running 16 ESXi …
A few weeks ago i received an email from a customer using VMware Data Protection (VDP) version 5.1.0.56.179 for their vSphere 5.1 (vCenter Server version 5.1.0 880146) environment. I thought this was a one time issue but a few days ago i received one more email from a another customer with the same issue so …
This blog post applies to the vCenter Server version 5.1.0.880146 and ESXi version 5.1.0.799733. Today i ran into an issue with the Snapshot Consolidate feature. The vSphere Web Client informed me that a “Virtual machine disk consolidation needed” was required for my VM. The virtual machine is backed up by vSphere Data Protection 5.1.0.56.179 and …
A few weeks ago, using vCloud Director (vCD) 5.1.2, i tried to test the vCD quarantine function which is all about getting in control over the procedure of uploading files to your vCD. When it is enabled the end user uploaded files will not be available before they have been accepted by a system administrator. A …
A customer contacted me the other day asking for a way to verify if the ESXi host TSM-SSH (SSH) service is running, and if so: Turn off the TSM-SSH service. Send an e-mail report including all ESXi hosts where the TSM-SSH service was stopped. The customer’s vSphere administrators sometimes enable the ESXi host TSM-SSH service …
I have previously written about a vCloud Director (vCD) implementation where the vCD based VMs must coexists with traditional vSphere based VMs in the same vSphere cluster, post available here. A few days ago one customer added an even more interesting parameter to such a solution. The customer has an existing vSphere environment, running both …
For the first time i have had a hard time installing vCenter Update Manager (VUM) version 5.1 (not U1 or U1a). The vCenter Server upgrade, from version 5.0, did complete without any errors. VUM was not used before meaning no upgrade was available. The installation failed in the end, when register VUM to vCenter Server, …
