[Koha] Suggestions of hardware

[Carlos Rodrigo Cordova Sandoval]

Hello

I need your suggestions of hardware to implement a koha server, with the
following requirements:

records: 47,000
items: 157,000
users: 3,000
libraries: 12

For the server I count on vmware virtualization,

That operating system ubuntu or debian recommend?
How many processors and RAM are needed?

and if the number of records and items I recommend mysql on a dedicated
server.


Thank you very much.
