[Ocfs2-users] broad topic: AoE vs iSCSI vs DRBD with OCFS2

[Florin Andrei]

For low-end deployments, a SAN can be replaced with a distributed block 
device, using something like AoE (ATA-over-Ethernet), iSCSI or DRBD.

Is there any document comparing these solutions, used with OCFS2 on top? 
Which one would you prefer with OCFS2? Which one would you avoid? Why?

The context is:
- low-cost deployment (avoiding full-blown SAN)
- OS is Red Hat or a derivative (CentOS, Oracle Enterprise...)

Things that matter, in no particular order:
- stability
- lack of hassles, at installation and later
- performance (as much as possible from such a low-tech setup)
