Check out the new Cisco 4080 Switch. It has suppors in the OS for active
clustering.

you gotta plug em into a hub right? So make it do the work for you.

> Hi all
> 
> Here's what I'm trying to do:
> 
> I have two RedHat Linux boxes that connect to the same Fibre Channel
> RAID array.  They are both webservers in a basic cluster - with a
> heartbeat between them to provide for IP address takeover if 
> one fails.
> 
> What I would really like is for them to both be able to serve webpages
> from the same filesystem on the array - preferably without a 
> single point
> of failure.  I've looked a bit at using NFS and also CODA, but neither
> seems quite right.  The RAID hardware I'm using doesn't seem to have
> the DLOCK support needed for GFS.
>  
> I've tried just having an ext2 filesystem on the array
> with one server mounting it readonly, but any updates made by 
> the other
> server are not visible to the readonly server until apache is 
> stopped and
> restarted (with the array umounted and re-mounted in 
> between)...there must
> be a better way...this is not so good because the web pages 
> are updated
> every half hour or so from a staging server using rsync over ssh.
> 
> I'm looking for ideas...any suggestions, war-stories etc would be
> very welcome.
