As Jorgen says not much of a question. few more details are required.
Are the 20000 windows desktops all on the same site or spread out geographically? Same for the servers?
If they are spread out how are they connected via WAN? Slow links, fast links? How many users? Do you use Active Directory? One forest? Lots of things to consider before a propper answer can be provided.
You should consider reading through this: https://technet.microsoft.com/en-gb/library/gg712681.aspx 
Basically though with potentially 22000 clients your Management Point is going to get busy (according to
this the ax MP client count is 25k). You may want to consider a CAS with two primary sites or maybe a secondary/proxy MP to better control the load on the MP. But this really depends on the topography of your network and where the clients are based geographically.
Hello,
Desktops are spread out within 6 sites:
- 2 main sites hosting 18,000 desktops with several buildings each... about 10-15 buildings...
(2 groups of building with FAST LINKS, split of 6,000 Desktops on the main site and 12,000 on the remote site)
... the link between the two sites is excellent there have not been issues in the past with SCCM 2007 between those sites. (SCCM all sites were hosted in Building 1 ONLY for the three sites)
- 1 site hosting 1,500 with 3 buildings
- 3 sites hosting between 50 desktops and 500 desktops  
- 1 main site 800 servers ( Data Center)
- 1 site 150 servers (Date Center)
- 1 site 50 servers (Date Center)
- Fast links everywhere: but in SCCM 2007 the clients were not reporting well!!!
- 25,000 users
- Yes we are using Active Directory, one forest, clients in different OUs with different policies and rights.
- Also Desktops as well as servers have different owning chart:
- Dept1 own the server Hardware, OS, SQL, Application
- Dept 1 own the hardware, Dept 2 own OS, SQL, Application
- Dept 1 own the hardware and OS, Dept 2 own SQL, Application
- Dept 1 own the hardware, OS, SQL, Dept2 own the application
So we should be able to delegate rights and privileges per groups
