HI.
I am not sure about the Archive Server.( i heard about Archive Link but not the Server)
If its archive Link, you can create content Repositories with the same in OAC0 and DCADMIN after Content Server Installation.
For DMS in seperate Server,
You will need Content Server 6.40 (Latest Version).
SAP INstallation Master.
jdk 1.7 (Since SAP installation Master Requires jre environment)
MaxDB 7.6 (above 7.6 are available in market place but they are not officially released with the Content Server6.4)
Its just a straight forward procedure.
Download the DVD imsages for content Server, MaxDB and SAP Installation master from Market Place.
Install Your Database (MaxDB)and create an Instance.
Content Server is installed via SAP Installation Master or SMWP.
Once you are ready with your Database, Follow the link

after the successful installation, you may start configuring the Content Repository in OAC0 tcode and CSADMIN tcode.
Cheers!
