This is the MogileFS storage daemon, which is just an HTTP server that supports PUT, DELETE, etc. It's actually a wrapper around Perlbal, doing all the proper Perlbal config for you.
In addition, it monitors disk usage, I/O activity, etc, which are checked from the MogileFS tracker.

If defined and 0, Perlbal::XS::HTTPHeaders will not be used, if present. Otherwise, it will be enabled by default, if installed and loadable.
