Citrix Studio vs Delivery Service Console

In Citrix Delivery Service Console, there is a node for Xenapp Servers, you can see each Xenapp server,  you can also put Xenapp servers in zones or worker groups. I cannot see in Citrix Studio where Xenapp servers node is and if you decide to put servers in worker groups or zones, where can you do that ?

Thank you

In xenapp 6\6.5 we use Citrix Delivery Service Console to view the farm settings and xenapp 7+ same call it as Citrix Studio and Citrix Director.

In XenApp 7.5 instead of using folders and Worker Groups to organize applications, servers, in Studio you organize the resources using a combination of machine catalogs, tags, Delivery Groups, and Delegated Administrators.

You must be referencing XenApp 6.5?  

I think I understand your question but first you must separate out Zone and Worker Group.  For now, at least.  If you are planning on active-active load-balancing with servers located in different zones that is another discussion.

The more practical explanation is a Zone is the accepted boundary for servers on the same physical LAN.

You can have XenApp servers on different virtual VLANs.  You can have them on different subnets, different broadcast domains but they are all located in State 1, City 2, Datacenter 1.

This would of course change if you entertain different Lines of Business that require different Farms or Sites.  So a Zone is a logical representation of your physical LAN.

Zone A is State 1 City 2 but Zone B is State 1 City 3 or might be State 2 City 4.

They are connected by WAN aka MPLS aka OC12 aka OC48 or maybe T1.

To understand workgroups you really need a background that started back with Presentation Server days and in to version 6.5.

You see, prior to Work Groups you had "Silos" and like some I've been using PVS shortly after Citrix acquired the technology aforementioned previous name of Ardence.  

This is another discussion relative to the implementations I've seen that attempt to use Versioning along with Replication but on same physical LAN segment.

You see, Ardence was more of a distributed model where it did not make sense to "stream" across a WAN so where we had offices at remote sites you would copy that image to another site but on the same LAN we still have implementations leveraging 4 PVS servers with 4 LUNS instead of 1 LUN and 4 PVS Servers.  The cost save is hard to measure when you have 5 images of 110 GB each and instead of 1 copy on the NAS instead you have 20 Copies at 110 GB each that must be copied to all LUNS.

The list of steps required to not missing a pvp file or make sure all the copies are done and not corrupt is a very long list.

So, to Workgroups; You see, each image had X number of applications.  In Presentation Server 4.5, for example, some using physical hardware started using GHOST to build one image, change the Datastore to Access Database, Sysprep, reboot, add to farm by "Silo"

Workgroups eliminates that overhead.  You can now actually have 1 image with all applications installed and instead of 5 Silos you have 5 Workgroups that can be applied to specific LOB applications rather than dedicated Silos.  It is another way to streamline and meant to help eliminate images and those other processes.

So the easiest explanation I have is a Zone is all the homes in one neighborhood where all the streets in said neighborhood connect without leaving that neighborhoold.

Workgroup's are the 'streets' in the neighborhood that create a logical group of "homes" in the neighborhood so that instead of all homes have access to swimming pool 1 they have access to swimming pool 2 only or might have access to all pools.  A primary different being if that community was gated your logical groupings would decide what users access cards would allow them to those streets for Pool 1 or Pool 2 or both.

That is the quick answer.

So your question is summarized by the fact that Zones is everyone in the same physical Neighborhood.  It impacts all the "Homes" on every street not the users.

Every zone has has a ZDC and most likely a Secondary ZDC although they are active\Passive.  You can have only 1 Primary ZDC per neighborhood but I can have unlimited workgroups.

In this case, you have Zone 1 consisting of 55 Homes.  But, I might have 10 Workgroups that divide the homes in aforementioned neighborhood into collections of Hosing Groups.  So, you might have 11 streets of 5 homes each but only one ZDC (Zone Data Collector).

The ZDC in this case might be the housing development community center where you go to buy the home.

Hope this makes sense.

You are Close ...
I was saying Delivery Service Console has better Visibility in matters of  how to manage your Farm.
for instance in DSC you can see each Xenapp server on the console and can see which users are having sessions connected on each server. you can see user sessions at the farm level also...

I know Xendesktop 7.6 has another tool call Citrix Director, I am not sure if it has good visibility as DSC does ?
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Citrix director is more used for reporting purpose, its very much helpful for fix the user issues.  for more details
Brian MurphyIT ArchitectCommented:
Director is all in the customization.

You can run "Insight Appliance" and having Netscaler you simply enable Appflow and point to the Insight Collector.

Then you enable the ICA Metrics in Citrix Policies like ICA Latency, roundtrip, et cetera.

Then you use Powershell to integrate that information into Director console.

Director is simply pulling from the database that is populated with the data from the "Citrix Management Service" aka Edgesight.

Between that and Site Collector data, then Insight Tab, then Custom Search - powerful tool.

Not to mention what you can do with Excel data extracts.

So which tool in Xenapp/Xendesktop 7.6 do you use to display your Xenapp Servers and look at user sessions on each server ?
Sekar ChinnakannuStaff EngineerCommented:
jskfanAuthor Commented:
Citrix Studio uses :
Machine Catalogs (Computers you deliver to end users)
Delivery Groups (user groups that will have access to the delivered machines and the applications)

Xenapp Servers are not displayed on the Citrix Studio
jskfanAuthor Commented:
On Delivery Service Console of Xenapp 6.5 you can see the Farm, Xenapp servers, worker groups, zones, and you can see user sessions to each object.

I do not see that on Citrix Studio,
Dirk KotteSECommented:
worker groups, zones, are no longer existent in XenApp/Xendesktop 7.6
these are features of IMA Architecture used by xenapp up to 6.5.
The FMA Architecture used now has other concepts.

studio is used to configure the environment primary.
(disabling of servers and some simple operations are able too)

director is for operations. Here you can see servers, sessions. You can disable servers, disconnect, monitor or mirror sessions.
You see statistics, session-loadtimes, from director.
With citrix-insight+netscaler  integration you get additional network-performance-data.
