During some recent Trend Micro Deep Security 9.0 implementations I’ve come across an issue while “Preparing” the ESXi 5.5 Host for Deep Security. This process is initiated from the Deep Security Manager and should normally install the Trend Micro Filter Driver and add some settings to the ESXi 5.5 Host. While preparing the ESXi 5.5 […]
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.
This blog post highlights the technical difference on how vCenter SRM4 and SRM5 do failover with Hitachi’s Virtual Storage Platform (HDS VSP). Credits to Saravanan Mahalingam for delivering this information. SRM 4 SRM4 does not support failback operation SRM4 uses horctakeover command for failover operation. Horctakeover command fails over to remote site and reverses the replication automatically when the […]
While designing for vSphere Auto Deploy you may want to group (categorize) your ESXi Hosts and attach a deploy rule (rule set) to them: You specify the behavior of the Auto Deploy server by using a set of rules written in Power CLI. The Auto Deploy rule engine checks the rule set for matching host patterns to decide which items (image profile, […]
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.
Within this article I will share some of the challenges faced while implementing a VMware Auto Deploy environment with DHCP for the Management Network. The environment uses an Infoblox DHCP/DNS appliance but contains some good-to-know things that are not Infoblox specific, so keep on reading. DHCP is configured to use mac-address reservations to ensure that […]
Within this article I will try to give you a clear vision on the HP Virtual Connect FlexFabric Mappings that HP uses to facilitate their blades with NIC’s and HBA’s. If you are looking for the Flex-10 mappings click here. In our example we use the HP BL460 Gen8 blade with a FlexibleLOM (LAN on […]
While troubleshooting the vSphere Authentication Proxy (vSphere 5.1) I ran into a bug which will I highlight in this article. After successfully installing the Authentication Proxy I discovered an error message in the C:\ProgramData\VMware\vSphere Authentication Proxy\logs\camadapter.log: 2012-xx-xx 14:03:35: Failed to bind CAM website with CTL 2012-xx-xx 14:03:35: Failed to initialize CAMAdapter.
I recently had some issues getting the vSphere Authentication Proxy Plug-in to be enabled within vCenter Server 5.1. This is the error message that was displayed: “The server could not interpret the client’s request. (The remote server returned an error: (404) Not Found.)”
