Well, I'm really after the speed it offers.

With lustre, from what I understand, I could use say 3 or 5 or 50
servers to spread the load across the server and thus have higher IO.
We mainly host shared hosting clients, who often have hundreds &
thousands of files in one account. So if their files were "scattered"
across multiple servers then the access to those files would be
quicker.

In terms of high availability, I'm thinking that if I use more servers
and thus have less load on each server, then the rate of failure would
also be less. I see they have a high availability option, but would
also be interested to know what was said about it. Would you can to
point me to the specific conversation about this?
