RE: Cheap way to practice clustering?

[James Montz]

If you just want to play and learn with Failover, you don't have to have
a multi-host aware storage solution.

I have a couple of test servers setup, just using their local disk for
storage.  I have setup several services (httpd, sendmail, imap, and
virtual IP) to fail over between the two servers, and has suited my
needs.  And if you really wanted to test an external storage source, you
could use an NFS mount.

The only difference in a production environment will be the presence of
the storage system, and this is basically just handled by defining the
shared file system as a shared resource.

Subject: Cheap way to practice clustering?

Hi all -

I posted about using firewire for clustering practice a couple of days
ago.  It turns out that this apparently requires a special, very
expensive firewire solution.

So I want to play around with clustering (as in high availability
clustering a la Red Hat Cluster Suite, not computational clustering) at
home so that I can become more proficient.  The problem is, I don't want
to buy a multi-thousand dollar SAN for my house.  I wanted to find a way
to do clustering on the cheap.  I am not sure what path to take, so I am
going to toss it to the list to see if anyone has any suggestions.  I am
totally open to older/used equipment.
> From what I've been told, I need a storage device which is multi-host

aware, so plain old firewire or even SCSI JBOD won't do.  I've been
looking at the specs at
http://www.redhat.com/software/rha/cluster/hardware/.

I'm leaning towards VMWare at this point, but I'd rather do it for real
than in virtual machines.

Any pointers?

Thanks!
Thomas

Hello friends,
Thank you for submitting the request regarding a
practice with clustering models.
I am also intrested in doing some practices with
failover and load balancing especially mail and web
servers.
If you have any idea to implement such a these
solutions without expensive hardware(especially
central storage) Please write for mailing
list.Normally I consider that I and other interested
guys are able to dedicate 2-3 fedora servers with
normal hardware.
I even invite these friends to talk more regarding our
experiences.
Your cooperation is highly appreciated.
Sincerely,
