Hi,<br>Presently, I'm having 3 600 000 fotos in average 50KB per one,
and 5 000 000 thubms in average 3KB per one, so its occupy in total
disk storage about 200GB.<br>I in peak hours traffic is about 5500 queries per second.
<br>Below is statistic of traffic from one domain :<br><span style="font-style: italic;"><a href="http://domain2.com/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">domain2.com</a>: (queries for file per hour)

would be able to obtain 20 units of sun x2100 M2, which each of other
has 2 SATA disks, two processors Opteron dual core. And such unit is
able to have max 64 GB ram. So, my question is how many units I'll
need? and how many ram per one? Does mogilefs see few disk like one virtual, and write and read data from each other at same time? The main purpose is to increase
the traffic from 5500 q/s to 10000 q/s (q/s - queries per second)
<br><br>Thanks for all solutions from you<br><br>Krzysztof<br><br>P.S sorry about my English, I hope, you understand me :) <br><br>
