We are 20 providers and a total of 60 users. We are using GE Centricity Practice Management and eClinicalWorks EMR. We are in a remote desktop server virtual environment running Windows 2008r2 64 bit that totally exceeds their configuration requirements. GE Centricity is telling us that they only support servers with only 20 users. I would like to know what practices are doing that have GE Centricity PM and/or EMR in a terminal server environment with more than 20 users. Any advice or input would be greatly appreciated. Thanks.

20 is nice! 13 used to be the theoretical limit.
We use CPS and we have a server or two that will hold up to 20-25 people max with no hardware or Windows related problems.
Are you having any problems related to the load of users on your servers? I would say as long as memory, CPU and network usage are not maxxed constantly you should be fine.

Hello,
Adding another terminal server may help you.We have over 100 CPS users with Hyper-V windows server 2008 R2 Terminal services. We have seven terminal servers that the users connect to via Round Robin DNS. Although this doesnt always distribute the work load evenly it works well. I think you can limit the number of users but havent gotten there yet.
We publish the RemoteApp and create a shortcut on the users desktop.
Hope this helps

We are mix, Citrix/ TS
we have 55 provider and a total of 210 users including the providers and only 3 terminal servers. and 2 citrix server
most of our external user connect using citrix but they are not more than 30-40 users at a time.
the rest 170+ use the 3 terminal server with no issue at all.

We have about 280 citrix sessions going during the day and we have the load spread across 14 servers. Our users utilize GE Centricity Group Management and GE Centricity EMR along with a few other aps. During hardware failures and maintenance we have run them on as few as 8 servers but we ended up having some issues. I would definitely not recommend going over 30-35 users per server.
Keep in mind that disk IOPS is a major factor in adding additional users to the servers. We started migrating some Citrix servers to SSD drives and the ones that are not on SSD are on 8x 15k SAS drives in a R10 array.
Are you trying to run all 60 users on 1 TS/Citrix server I would say you are going to have a potentially bad user experience. You did not mention which technology you are using but here is a citrix blog on number of users per server, server vm's per host, VCPU/Memory per VM etc. http://blogs.citrix.com/2013/01/07/whats-the-optimal-xenapp-6-5-vm-configuration/
Even if you run MS RDP/TS servers it should be fairly similar in terms of resources since citrix is just an overlay to RDP/TS environments.
EDIT: When I say server, I am referring to a VM on a server, not a physical server.

Did you ask this question because you are experiencing issues and GE is blaming the number of users or because you are not experiencing any issues with it but GE will not support your environment because of the number?
If you are experiencing issues perhaps we could help you out more by getting more details about the number of sessions and type of hardware involved. You said that you exceed their requirements. Does that mean you exceed the specifications for what they deem a 20 user system but you are putting 60 users on it?
It would be helpful to know the following: Number of active sessions at peak. (I ask for sessions because our doctors end up using 2 sessions at a time, one PC and one or more laptop)What type of technology are you using for access (RDP/Citrix)? Are you using virtualization on the server or is is a physical server? Amount of Memory? CPU Speed, Number of Cores, HyperThreading, etc? Hard Drive number, speed, configuration (raid settings)?

We are more on your size. We have a total of 80 users but no more than 70 on in a given day. We have 3 Citrix boxes and a load balancer to throw the users between the boxes. We actually crashed this morning but that's because users decided they wanted to use one server over another... Our servers are named after cars... Chevelle, Corvair, Crossfire... guess which one everyone wanted on...

We use citrix xenapp and vmware and put 20 to 25 users per VM and 3 to 4 VM's per physical host. So 60 to 100 users per physical server without issue.
