[collectd] Collectd performance issue

[Giuseppe Fiameni]

Dear all,
our company is going to use collectd software to monitor its ICT 
infrastructure.
For that, I was wondering which is the best way to configure collectd
in order to monitor many servers. Actually, the real intention is to take
the machines status under control from one single point of access by using
the data push model.
After some tests, I noticed that collectd demon "collects" nearly 50MB 
of data
per year (basic configuration). Thus, it seems that collecting data,
let me say for 200 servers (200 x 50MB ~ 10 GB),
could be quite difficult if we'll decide to get them in one single 
server (Forward=true).
The main server should be equipped with a very fast storage system to 
keep being
responsive while end user ask for monitoring graphs.
What is your opinion about ? Could you please suggest me which the best
way to use collectd is ?

Many thanks in advance.
Best regards,
Giuseppe
