I am looking to install DPA, VMAN, SRM and NPM asap, do they need installing on separate servers (seem to remember seeing a thread regarding DPA and NPM not installing on the same server).
I plan on creating a single SQL server to host the DB's for the software.
Anything else that I should be aware of?
Typically the suggestion is to install the DPA Server and its repository on a different host than the Orion installation containing VMAN, SRM, and NPM. Otherwise, they will fight each other over shared CPU, I/O, and Memory resources. They can coexist together, but as you increase the number of entities monitored and the volume of information grows, the contention will increase.
