Filtering and Auditing within vRealize Log Insight

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 […]

Reset VMware Auto Deploy Database to default

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 […]

The OVF package is invalid and cannot be deployed.

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”.

Migrate to new vCenter Server while using dvSwitches

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 […]

Datacenters vs Clusters within the vCenter Inventory

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 […]

How to get Device Identifiers for I/O Devices

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 […]
