Title: Virtualisation
Post by: StuartS on 22 Jul 2011 08:50:35 AM
Hello

I am putting together a new development environment.  My current thinking has been about using a server with virtualisation to deliver several environments, 8.4.0 fp1, 8.4.0 fp2, 10.1, etc.  SQL and Oracle. Physical jobservers would then be used to connect to an environment.

Does anyone have any experience of doing this and do you have any ideas with regards the hardware required/suggested.

I am considering one box for use with Cognos Planning, and one with Cognos BI.

Thanks

Stuart

Hi Stuart,

Using Virtual machines is certainly something that's being leveraged more and more lately and assuming you have the right hardware, you can actually get better performance in job processing utilizing a 2 x 4 core virtual machine environment vs a single 8 core physical machine.

This question was brought up very recently on these boards, you can find the thread here:

Cheers,

Hi Stuart,

Something to consider for your specific plan is that your physical job servers will be of one particular EP version, so wouldn't be well-suited to hop between environments unless you're planning a quick reinstall each time because the job server install is pretty config-light.

As Eric's mentioned though, running virtualised job servers works fine provided you have MMU virtualisation enabled in your environment.

Cheers,
Alexis

Alexis, Good Point on jobservers.
Eric, thanks for your reply.

Whoops, good catch, Alexis.  I should make sure I completely read the post before responding. ;)
