We have quite a few different storage solutions, and among those most have really bad command line interfaces. At least one of them is web only, and trying to wrap it with WWW::Mechanize or something similar would be difficult due to all the fun stuff they do with javascript. Other solutions even want you to have flash support.
Most of us (Ingvar included) prefer CLI any day. I'm so looking forward to the day where all these SAN's are retired, and we're running Ceph for all.
