During a recent Deep Security implementation we’ve experienced post-deployment issues with the Deep Security Virtual Appliances (DSVA’s). After Deployment of the DSVA’s you will get a “Communications Problem” reported from the Deep Security Manager. By the way, the Deployment of the DSVA within ESXi 5.5 has got a known issue of not working on the […]

Deploying DSVA on ESXi 5.5 fails.
This article describes the scenario where you will experience a timeout from vCenter while deploying the Trend Micro Deep Security Appliance 9.0 (DSVA) on an ESXi 5.5 Host. I got some information from Trend Micro about this issue, which can simply be resolved by retrying the deployment. So what happens? The first time you try […]

“Prepare” ESXi 5.5 Host within Deep Security 9.0
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 […]

BL460c Gen8: Not detecting SD-Card during ESXi 5.1 Installation
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:

Auto Deploy: ESXi Stateful Install with multiple LUNs connected fails
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.

Failover difference with SRM4 and SRM5 on HDS VSP
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 […]

vSphere Auto Deploy: Consider the Asset Tag to categorize ESXi Hosts
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, […]

vSphere Authentication Proxy: Cannot complete login due to an incorrect user name or password.
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.

ESXi Hostname lookup with DHCP/DNS
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 […]
