Hi Experts,

We currently have a ESX 4.0 environment with multiple ESX hosts/datacenter, and VMs for each host/datacenter

My manager wants me to evaluate an application called Siebel, which high-level architecture is described in the following link:

http://siebeloracle.wordpress.com/2009/07/04/siebel-architecture-siebel-server/

Can you please indicate what are the important questions I should ask the vendor to evaluate and prepare a re-design solution to our current ESX environment?

For Instance, a simple question would be is the application compatible with virtualization? If so, is it compatible with VMware?

I would like to prepare an application questionnaire, so I can gather as much information as I can

Can anyone please point me on the right direction?

*What are the system requirements?
*Are their limitations to virtualizing the application?
*Are there hardware compatibility issues to be aware of (storage/SAN/disk or RAID type, processor type/model, etc.)? CPU Affinity and/or RAM Share/Reservation requirements?
*What are the DB requirements? Does it have to be local or can it be remote? What DB Server is supported? If local, are their size limitations on the DB? What are purge requirements/best practices for the DB/log files?
*Are there limitations as far as # of VMs that can be on the same host as this potential app VM?

Hmm...that's about all I can think of at the moment.

Hope that helps.

The biggest question you need to ask the Vendor is:-

Will they support this application if you host it as a VMware vSphere Virtualised guest?

The application will be compatible with all computers, whether physical or virtual, it's whether they will support the virtualised environment.

Another question is licensing, do they charge per Core or Processor, some organisations charge per Core the software is used on.

Some organisations like Oracle, take this approach

"Be aware that Oracle's official position is that they do not support Oracle in a virtualized environment beyond the operating system.  If there is a problem and you need Oracle's support, they may very well tell you to put it on a physical server before they will support you."
