iSCSI and clustering with FreeBSD

Peter,

How far along are you in your freebsd iscsi development ?

Does an iscsi driver for freebsd exist ?

Appreciate your time.

Anthony L Centore II

How would gmirror and ggated help?

the web-cluster through the kld!

I will implement the web-cluster by the loadable module  based on the tcp/ip stack code ,but ,the symbol
definitions in the loadable module will conflict with the orignal network stack when the module is
loaded. 
how do i resolve it?
does the loadable module have independent namespace?
i remmeber that the symorder can resolve it in freebsd 2.2.6 ,but i don't find it in freebsd 5.3!
can you help me ? thanks 

                                          shiner

Replicate data between two hosts, but it not very fine solution -- cached data not replicate to second node,
when first node die.

Introduction & RE: Clustering with Freebsd

Hello all,

My name is Philip Elder. I reside in St. Albert Alberta, Canada.

My wife and I run our own I.T. business here primarily focused on Windows
infrastructure though I still use the command line more than the GUI. :D

I am pretty green when it comes to FreeBSD. I am learning, slowly. My goal
is to build clusters, cluster based storage solutions, and some other ideas
jumping around in my mind. I chose FreeBSD because of its stability. BTW, I
do not have any programming experience at this time but I am willing to
learn to as well. I do have a fair amount of server based infrastructure
design, implementation, and support experience though (I've been in the
industry since the early 1990's).

I have been doing a lot of research and am wondering if perhaps this may be
a place to start as far as a file system foundation:

http://wiki.ethereal.com/ATA_20Over_20Ethernet

Here is more from the developer:

http://www.coraid.com/documents/SATAEtherDrive.pdf

Please feel free to let me know if I am way off base here as this is a good
way for me to learn! ;)

Thanks!

Philip Elder.

There are Linux-based clustered filesystems already extant.  It's generally
more efficient, I think, to do the clustering at a higher level than down at
the device level (I haven't read those documents, but "ATA over Ethernet"
sounds pretty low-level to me).

You might take a look at the stuff in OpenSSI, http://www.openssi.org/,
for a few pointers or ideas.  Certainly there's a clustered file system
there but it's by no means the only one.
