Core Team
Patrick Donnelly
IRC: pdonnellPatrick Donnelly is a software engineer at Red Hat, Inc. currently working on the Ceph distributed file system. In 2016 he completed his Ph.D. in computer science at the University of Notre Dame with a dissertation on the topic of file transfer management in active storage cluster file systems.
Ilya Dryomov
IRC: disIlya has been working on Ceph since 2013, originally focusing on the Linux kernel RBD driver. Currently he serves as the technical lead for RBD and the maintainer of the Linux kernel client and also contributes to RADOS primarily in messenger and cephx areas. Previously he was involved with Btrfs and HAMMER file systems.
Neha Ojha

Ernesto Puerta
IRC: epuertatErnesto was the Ceph Dashboard component lead from 2020 to 2022. He previously worked at Telefonica R∓D, Alcatel-Lucent, Bell Labs, and Nokia, where he first came to know about Ceph, for a Cloud Video Storage project back in 2015. After that stimulating experience, he joined Red Hat in 2018 and has since contributed to the Ceph Dashboard project, trying to apply his expertise as a Ceph user. Ernesto holds a master’s degree in Telecommunications Engineering from Universidad Politénica de Madrid and currently lives in that very city, famous for its fried calamari sandwich.
Yehuda Sadeh
IRC: yehudasaYehuda has been involved in Ceph since 2008, and has been working on various related projects and subsystems. He is the original developer of the RADOS Gateway (RGW) which he currently co-leads as part of his work at Red Hat. He also worked on multiple other Ceph projects, such as the Linux kernel Ceph filesystem module, and RBD. Notable other Ceph modules that he initiated along with Sage Weil are the Linux kernel RBD module, the RADOS object classes, and the cephx authentication. Before joining Ceph, Yehuda worked in various start up companies, where he developed various storage and networking solutions. He holds a Bachelor degree in Communication Systems Engineering from Ben Gurion University, and a Master degree in Computer Engineering from Tel Aviv University.
Sage Weil
IRC: sageSage Weil is the founder of Ceph. He also was the creator of WebRing, a co-founder of Los Angeles-based hosting company DreamHost, and the founder and CTO of Inktank. Weil earned a Bachelor of Science in computer science from Harvey Mudd College in 2000 and completed his PhD in 2007 at the University of California, Santa Cruz working with Prof. Scott Brandt on consistency protocols, data distribution (CRUSH), and the metadata manager in the Ceph distributed file system.

Zac runs the monthly DocuBetter meeting and is (as of 2021) engaged in an ineffably tedious line-by-line edit of the Ceph documentation. Zac encourages you to write to him with your complaints about the Ceph documentation.
Mark Nelson
IRC: nhmMark joined the Ceph team in January 2012 and has 12 years of experience in distributed systems, HPC, and bioinformatics. Mark works on Ceph performance analysis and is the primary author of the Ceph Benchmarking Toolkit. He runs the weekly Ceph performance meeting and is currently focused on research and development of Ceph’s next-generation object store.
Mike Perez
IRC: thingeeMike is the Ceph Community Manager at Red Hat. Being a contributing member of OpenStack since 2010, he has served as a core developer for the OpenStack block storage project Cinder and as a PTL for the Kilo and Liberty releases. During some of this time, he worked for DreamHost in helping with their OpenStack public cloud, one of the first large production deployments of Ceph, and helping with integrating a variety of block storage solutions like Ceph in Cinder. He later joined the OpenStack Foundation to help with the success of cross-project initiatives and the overall quality and health of the project and community.
When Mike is not trying to make a computer work, he can be found: dancing, getting his hair done, playing with modular synthesizers, and doing karaoke for your entertainment.
