(RADIATOR) database's in same server as radiator?

[onrubia carlos]

Hello,

I have looked at the mailing list to find an aswer on my problem but
even if this topic is rather present in the mailing list, I
do not know what to conclude for my own situation.
That's why I post this mail in order to have a clear view on what to
do ... and what not to do!
I hope I will receive a clear answer.

Presently my radius configuration is the following one:

- 10 radius servers (radiator 3.11) with debian linux (running with
one authentication configuration and one accounting configuration)

  Hardware is: Proliant DL360G3 - 2Gb memory - 2 processor Intel(R)
Xeon(TM) CPU 2.80GHz - 12Gb disk

- 5 slaves dB's servers (debian linux) on mysql where the user profile
is present (essentially login/psw)
   These 5 db's are synchronised with a master db where the
provisioning is done.

   Hardware is: Proliant DL360G3 - 2Gb memory - 2 processor Intel(R)
Xeon(TM) CPU 2.80GHz - 12Gb disk

- 5 accounting db's servers (debian linux) on mysql where I insert the
accounting requests.

  Hardware is: Proliant DL360G3 - 2Gb memory - 2 processor Intel(R)
Xeon(TM) CPU 2.80GHz - 12Gb disk

The db's are reached from the radius servers via a Load Balancer (see
here below a part of the configuration file)


Authentication

Question:
---------

I need to make the renewal of all these servers and I need to know
what kind of servers to choose for the new set-up.
As the standard servers for the renewal in my company are more
powerful that the present one, I am thinking of putting all the
functionnalities in the same server (radiator, authentication db and
accounting db).
I will this way use less servers and skip the mysql queries (select,
insert, delete) via the network (Load Balancer).

I guess the mysql access will be then reduced a lot; moreover each
radiator will have its own DB's ( a fail over DB - other server- will
be put in the configuration
file in case of local mysql problem)

I think of the following situation:

10 servers (of less? - performance to be tested) with the following hardware:

    ==> DL380R05 - 1 (or 2??) processors (dual core:Intel 5150 -
2,66GHz/1333 FSB ) - 4 Gygabytes of memory - 2 disk of 72Gb - 4 disk
of 146 Gb.


What do you think?
Any blocking points?
Is this set up (radiator/DB's in the same servers) often used?


Thanks in advance for your feedback, remarks.


Carlos,
