Yes that my infrastructure, besides, the tfs build machines and test
machines including SCVMM are deployed in China.

 

Can both the TFS PROXY and TFS app tier exist in China and cooperate
together? Because SCVMM and test controllers/machines are in China which
requires to connect to TFS app tier

If I understand your infrastructure correctly, you're saying that you
have 1 TFS database, with app-tiers connected to it located in USA and
China.

That means that China app-tier is accessing the database over the slow
link - this is not a recommended/supported TFS configuration.  TFS
requires a minimum bandwidth of 1Mbps and a maximum latency of 350ms.

 

 

The generally accepted solution to this problem is to install a TFS
PROXY at the remote site (China), and configure the China clients to use
it.

You can also setup a scheduled task on a machine in China that does a
GET using the PROXY every hour or so, so that the PROXY has the latest
version all the time.

The infrastructure is, database is in USA, one app tier is in USA,
another app tier is in China.  Now, if someone upload a big file (1GB)
into source control through USA TFS server, how can user in China
download that big file through China TFS server QUICKLY?  Currently the
tfs users in China download that file through China TFS server slowly,
it usually takes several hours.  Since USA and China have working time
difference, can the two TFS server automatically sync after USA user
upload big file into source control through USA tfs server at night,
then in the second morning, China user can download that file just like
from local ?
