Hello, Lately I've been working on network automation stuff for HamWAN, and I'm at the point where storage systems have to be dealt with. I'm wondering if anyone in the group has knowledge to provide some design feedback in distributed storage systems. Not from a "how to use it in AWS" perspective, but rather how to design them ground-up. Ideally we want a couple abstractions available network-wide: 1) A global DB (NoSQL should be fine, and Cassandra is looking possible for this) 2) A global FS (GlusterFS is in very early stages of being evaluated for this) Each of these has to have N-way redundancy where N is the # of sites we have, with each instance being capable of continuous operation even if it finds itself on its own network island for a while. Conflict resolution / merging when the network heals is a must. --Bart
