Replicate data of filesystems inside AIX.

Hi,

Is possible to replicate data from different filesystems in AIX? For example:

We have AIXs servers that has disks, VGs and LVs from a DS5100 (A). But we have another DS5100 (B) storage outside our building and we want to replicate theses disks, VGs and LVs between theses two DS5100 (A) and (B)

NOTE: I know both DS5100 can replicate their LUNS, but we want to replicate on the AIX OS side.

Is it possible?

Is there comercial software for this?

Thanks..

Hi again,

what exactly do you mean with replicate?

You can do regular LVM mirroring, of course.

Just make sure that AIX can see the disks on both sides, so you can add them to the VG in question and mirror the LVs.
Possible speed differences don't matter, AIX will read from the fastest copy, and as lon "miiror write consistency" is not enabled (Y/A) write I/O will be marked complete as soon as the fastest write is done.

I have to leave now for 2 hours or so!

CU l8r!

The fact is both DS5100 (A) and (B) are now connected via fiber cable and it's too expensive (remember the global crisis) for our business. Both DSs replicate multiples LUNs using this way. So, we want to disable this fiber cable, and see if there's a way to replicate theses LUNs using the 1Gethernet connection between both buildings. So, I don't know if it's possible or not, or if there's adapters from fiber-ethernet in the DSs side.

Well,

the DS5000 doesn't support direct Ethernet connections.

Fibre Channel over Ethernet (FCoE) might be an option here.
I have relatively little experience with this, unfortunately.

Anyway, here is a Redpaper:

http://www.redbooks.ibm.com/redpapers/pdfs/redp4493.pdf

As for expensiveness: The minimum you need to run FCoE is new network adapters which are able to carry FC (e.g. CNA, "Converged Network Adapter") and at the access layer side FCoE capability in your network switches.

I'm not sure if all this is a real alternative though!

Umm, why do you say "I'm not sure if all this is a real alternative though!"?

Performance issues? Bad experiences with FCoE?
