Thin Client

Hi There,

I am in the process of evaluating the deployment of thin clients within our network, I haven't had a great deal of exposure with thin client technology however I am aware of basics i.e. client connects to Windows Remote Desktop Services (terminal Server) and all required apps to be accessed by the client are installed into the remote desktop application repository etc... what I am stuck with is the following:

> we have a terminal server which currently has approx 4 GB of RAM is this enough to connect approx 10 - 15 thin clients?

> storage - local (server) storage is minimal and we use mapped Iscsi targets instead, will these still work via thin client?

> what CAL's will I require and how do I find out what CAL's I already have?

> Any additional deployment related issues and considerations to be aware of?

Any suggestions advise and suggestions anyone has would be greatly appreciated.

Thanks again
A

You may have enough to connect 10 to 15 users, but it depends how your users work,and what applications they are accessing.

What operating system are they connecting to?

When clients connect to the server, the user will be able to use any storage thats available to that users session, or attached to the server.

You need normal Server CALS and Remote Desktop CALS, its unlikely you have these and you will need to purchase, terminal server licening operates in evaluation mode for 120 days, but you will need permanent CALs after this.

Test, Test, Test and Test, and when youve finished testing test again.

I would start with a pilot, of a few users 2-3, and then build up over weeks to the final concurrent max limit.

Thanks for your prompt response,

Is there a way to identify if we already have the Server/ remote desktop CALs required?

Thanks,

Do you have Terminal Server License Server? if so they will be registered in the license server.

Hi There,

Attached is a snapshot of our licensing manager. I know the Windows 2000 Server Built-in TS CALs are used for devices that connect to a 2000 Server Terminal Server. It appears as though we have 5 RDS CAL;s which can be used per user that will be connecting to your Server 2008 R2 Foundation via RDS for non-administrative purposes. Will these CAL's suffice for connecting (5) thin clients to the terminal server to initiate remote desktops service?

I am still somewhat confused with the licensing required so if someone could please clarify withas much details as possible as to exact licensing required etc.. that would be greatly appreciated.

Thanks

Yes, you have 5 TS CALS.

TS CALS are used to connect a Thin Client device or PC to a TS session.

What’s the difference between a RDS CAL and a TS CAL?

Also, there are User CAL and Device CAL variants.

Basic Idea is this.

User CAL is per User, Device CAL is per device.

1 Device CAL for 1 PC, means multiple people can use that PC to connect.

1 User CAL, means 1 User can connect from any PC or Device
