<DIV><FONT face=Arial size=2>Hello Andrew,<BR><BR>- How many nodes?</FONT></DIV>
<DIV><FONT face=Arial color=#008000 size=2>4 nodes</FONT></DIV><FONT face=Arial
color=#008080 size=2></FONT>
<DIV><BR><FONT face=Arial size=2>- How many apps?</FONT></DIV>
<DIV><FONT face=Arial size=2><FONT color=#008000>about 10</FONT></DIV>
<DIV><BR>- How many apps will users interact with directly? (This gives a
good<BR>indication of how many IPs you need)</DIV>
<DIV><FONT color=#008000>about 5/8, in fact apache manage 2 public class IPs
with virtual host</FONT></DIV>
<DIV><FONT color=#008000>so other apps work interactly with it.</FONT></DIV>
<DIV><BR>- Do the apps talk to each other?</DIV>
<DIV><FONT color=#008000>If you talk about apache, php, perl, postgresql, so
yes.</FONT></DIV>
<DIV><BR>- Will apps be accepting requests on more than one node at a time?
(If<BR>so, only then do you need to involve CLUSTERIP)</DIV>
<DIV><FONT color=#008000>yes if possible, to increase request number, but maybe
load balancing is more</FONT></DIV>
<DIV><FONT color=#008000>adapted</FONT></DIV>
<DIV><BR>I planned to use drbd to manage data between nodes also. but yet I'm
not sure of this solution.</DIV>
<DIV>My real goal is to increase the number of clients from apache and
applications I developped with</DIV>
<DIV>HA solution in case of failure. But my system is restricted to host on the
same machine all applications</DIV>
<DIV>I use (Web, DB, my apps) if not it will be very complex to manage it. the
most important is also that</DIV>
<DIV>the client needs to stay on the same node once he logged into the
system.</DIV>
<DIV> </DIV>
<DIV>Thanks for your help and good luck with pacemaker</DIV>
