The article below describes one of the ways to implement vRealize Log Insight into an environment where a (security departments) syslog server is already available and where this server ideally only receives filtered events and auditing information around changes to the filters. Let’s start of by saying that with the introduction of ESXi6, VMware makes […]
One of the things that the VMware Auto Deploy Database contains is the ESX Images that are uploaded and related to the DeployRules that are created. For instance, if I add an ESXi Image to the software depot and create a new DeployRule using the following commands: Add-EsxSoftwareDepot “VMware-ESXi-6.0.0.update01-3380124.x86_64-Dell_Customized-offline-bundle-A04.zip” Get-EsxImageProfile | ft -autosize New-DeployRule -Name […]
While deploying a random OVF image within vSphere I received the following error message: The provided network mapping between OVF networks and the system network is not supported by any host.
While installing new HP BL460c Gen8’s (Xeon E5-2680 v2) we discovered some strange behavior while setting the HP Power Profile setting to “Maximum Performance”. It appears that this setting causes the ESXi 5.1 Installer to not see the Internal SD-Card as storage device anymore. Default BIOS Settings give us this, which is good:
Recently I have been experiencing some troubles with VMware Host Profiles, Auto Deploy and the stateful install of ESXi 5.1 (Update 1). After the Host Profile gets applied, the system eventually times out with the message: “The request failed because the remote server took too long to respond” as indicated on the screenshot below.
During configuration and testing of the vSphere Authentication Proxy we discovered some problems that make the use of the Authentication Proxy very unreliable within multi Domain Controller environments. In our case we are using the Authentication Proxy in conjunction with vSphere Auto Deploy but the problem also occurs in scenario’s without Auto Deploy.
During vSphere 4.x to 5.x updates I occasionally run into the situation where dvSwitches are used on the current vCenter4 and the customer wants to install a fresh copy of vCenter5 (with a new dvSwitch). Within this article I will describe a minimum downtime (1 ping-loss or less) procedure to cover this, guided by pictures […]
Recently I got involved in a discussion about “Creating multiple Datacenters with one Clusters rather than one Datacenter with multiple Clusters” First of all lets get the definitions of these objects summarized (as stated in the vSphere Datacenter Administration Guide) Clusters A collection of ESX/ESXi hosts and associated virtual machines intended to work together as […]
After working for VMware for over a year I decided to take the next step in my career: to start Van Ditmarsch Consultancy As a contractor I will be available to do Virtualization Consultancy, primarily focused on designing, implementing and/or validating VMware Virtualization solutions with a strong focus on business continuity, high availability and disaster recovery.

Recently I got a few questions about the VMware HCL and how to verify I/O devices without knowing all the key details of the device. Let’s start of by looking at the VMware HCL, note that there are additional fields on which a search can be done for I/O Devices. The Device Identifiers are separated into the following items: VID […]
