Sage Weil helped developed Ceph as part of his graduate studies at the University of California, Santa Cruz. After graduating he continued to develop the system and build an open source community around Ceph with the support of DreamHost. In 2012, he co-founded Inktank to productize Ceph for the enterprise. Inktank was acquired by Red Hat in 2014, where Sage continues to lead Ceph development.
