Citrix Mobility Paris 13

Written by Ingmar Verheij on June 10th, 2013. Posted in Opinion article

On April 4th this year Citrix announced that no Synergy would be held in Europe, unlike previous years, and a new approach for the customer conference strategy was introduced: multiple regional mobility events.The article insinuated that Synergy Europe was replaced with the local conferences, starting with three mobility events (in Paris, Munich and London).

Today I’ve attended the first Mobility event in Paris with fellow peers Kees Baggerman (@KBaggerman) and Barry Schiffer (@barryschiffer) and I would like to share my experiences with you.

Citrix Web Interface shared configuration the right way

Written by Ingmar Verheij on April 21st, 2013. Posted in Citrix

Configuring sites on multiple Citrix Web Interface servers can be cumbersome. It is a repetitive task that needs to be executed exactly the same on each Citrix Web Interface server. Missing one setting results in a inconsistent environment, and as we all know those situations suck to troubleshoot.

Shared Configuration

Fortunately Citrix came up with a solution: shared configurations. With shared configuration slave servers use the configuration of a master server, all the changes needs to applied once on the master servers and the slave servers inherit the same configuration.

Why is Citrix refusing License Server VPX support for vSphere?

Written by Ingmar Verheij on February 5th, 2013. Posted in Citrix

With the release of Citrix XenServer 5.6 Citrix also released a new virtual appliance dedicated to licensing, the License Server VPX. The appliance is available since July 2010, in the 2.5 years the appliance is available only Citrix XenServer is supported.

Citrix ReadyIf you’re company is using VMware vSphere (or Microsoft Hyper-V) you’re unable to use the virtual appliance. Citrix refuses to release an appliance for other hypervisors then their own, let alone supporting other hypervisors. Technically it shouldn’t be too difficult to support other hypervisors (some people tried), they already do for the NetScaler VPX.

Who needs ISO for Citrix Provisioning Services?

Written by Ingmar Verheij on February 5th, 2013. Posted in Provisioning Server

In a previous article I wrote that for streaming vDisks to endpoint you don’t necessarily need PXE, you can also attach an ISO to the virtual machine (“Who needs PXE for Citrix Provisioning Services?”). Although this eliminates the dependency for a PXE server (which is challenging to make high available), mounting an ISO file to the CD rom of a virtual machine creates another problem in some hypervisors.

When a hypervisor host needs maintenance a (storage) vMotion is a good way of moving all systems with no downtime. Mounting an ISO file breaks the ability to vMotion with some hypervisors.

Citrix XenServer and VMware vSphere 5 (Hyper-V I’m not sure of) can mount ISO files from shared storage, so this does not apply to all situations.

Fortunately the bootstrap can also be placed on a virtual hard disk (VHD). In this article I’ll guide you step-by-step how this is done. In this example I’m using VMware vSphere 5 but most steps are equal for other hypervisors.

Netscaler X – Connection limit to CFE exceeded

Written by Ingmar Verheij on August 27th, 2012. Posted in Netscaler

Connection limit to CFE exceededWhen you try to connect to the admin console (dashboard) of a NetScaler X you get the error “Connection limit to CFE exceeded”. If you login via SSH is seems the credentials are invalid.

Users with a different username are able to login. In this example vtsha_admin is unable to login, nsroot can login..
