You want to protect against phisycal loss of your disk chassis. Every vendor has it's own proprietary mirroring system; see what netapp, IBM, HP, mcsq have to say. Else see if you can publish local and remote LUNs on the same SAN (*WDM on a dark fiber) and make an LVM mirror with them. It would require some serious maintenance ;)

Subject: Re: [Linux-cluster] Distributed Replicated GFS shared storage
Maybe DRBD is what you are looking for. www.drbd.org
But, I thought the best way to do it would be using a storage mirror
technology as "Enhanced Remote Mirror" by IBM, Data Replicator by
