Hi Ronnie You might find in the future that it will indeed be cores you run out of when you go to XenApp 6/Server 2008 R2. When we spec up servers, we try and make sure that we get as many cores as possible. As an example, a DL380 G7 can now hold 384 GB or RAM but is limited to 12 cores currently. As for your current servers, couldn't you install XenServer or ESXi on them and then take advantage of the memory you aren't using?

We currently get to approx. 20 users per box as we only run 2003 with XenApp 5. I do plan to move to 2008 R2 XenApp6 sometime next year. Currently I have a mix of HP DL 360 servers. Which are quad core x 2 processors. I have two DL 360 G6 servers which I feel are over specked with 4 quad core processors and 16 Gb ram, again only running 2003 so only using 4GB. There barely run past 2-3 % under full load. My question really is: As I always run out of memory before anything else is there any point paying for 4 x quad core processors or should 2 be fine. Keeping in mind that I will try and go 2008 R2 and XenApp 6 next year if all goes to plan. I know this is kind of how long is a piece of string question. But any feedback would be appreciated.
