Re: [Linux-cluster] WebFarm using RedHat cluster suite ?



Hello,
I think the best way to tell what storage or infrastructure would be the best 
is to know more about your current setup and what issues with that you want 
to get ahead of.
For example: if you really think about using iscsi, I don't think that SCSI or 
SATA drives make a big difference - depending on how many drives you use. But 
if all webservers currently have locally attached disk drives you want scale 
too linar with exchanging and IDE/parallel-SCSI Bus with an network topology 
using Ethernet. 
But my opinion is: if you have a lot of I/Os make yourself mostly independent 
from the latency of an ethernet and rethink about using Fibre-Channel with 
GFS.

But the best advices could be made if you make your current setup and the 
things you want to achieve more clearly.

Regards Marc.
