Hi,
1. Can SIC be installed on GUP server and operate?
--> If GUP is installed on Server operating systems then SIC can be installed on the same, pre-requisite are important to know.
Pre - Requisite for SIC:
Install .net Framework 4.0.
Windows 2003/2008.
2. If #1 is yes, what will be the minimum specification for the server (SIC + GUP) be?
--> Actually SIC and GUP are two different components and if they are meeting with their minium requirements then it will work without any issue.
SIC System Requirements Description
Software system requirements consist of the following:
- Windows Server 2003/2008
- NET Framework 4
CPU size : : Shared Insight Cache must be installed on a dedicated server or virtual machine.

3. If #1 is yes, how many client can a SIC + GUP server can support? (I know it depends on the specification, so please give specification and the client size)
--> I believe there is not any limitation for SIC however single GUP can support upto 10,000 clients. Out of 8K how many virtual machines are there? SIC is specifically designed to improve virtual machine scan performance.
I would suggest to use two different machines if possible because if that machine goes down then you may loose two services at a time.
