11:10Distributed storage system architecture and Ceph’s strength

From local storage systems to regular NAS, explore the reliability structurally and discuss considerations from a distributed system perspective. Finally, talk about the advantages and disadvantages of Ceph and what workloads are useful.

11:50Role of RocksDB in Ceph

In Ceph, RocksDB is used by default as a Metadata store for stored objects. However, this is not limited to providing critical features for top-tier applications such as RadosGW and MDS, and has a critical impact on performance. Surprisingly, however, many people tend to think of RocksDB as a black box and not pay attention to it. While looking at the internal logic of Ceph and RocksDB, I would like to look at the impact of RocksDB and introduce some points to note.

13:50Ceph case study and large-scale cluster operation plan in NAVER

In this pressentation, we will look at NAVER's case study of Ceph and how to operate storage. We would like to explain the problems and solutions that we struggled with when introducing Ceph and provide useful information for companies that want to adopt Ceph.

Jangseon Ryu and Hyun Ha
14:30A New MDS Partitioning for CephFS

This talk will present a new MDS partitioning strategy for CephFS that combines static pinning and dynamic partitioning with the bal_rank_mask option based on user metadata workload analysis. We will also share our experiences with the implementation of these optimizations in our production service and the results of our experiments. Finally, we will discuss how we can contribute our work to the Ceph community.

Yongseok Oh
15:20Revisiting S3 features on Ceph Rados

In this presentation, we will first explore the S3 API execution path from a client to the Ceph Object Storage Daemon (OSD). It will cover how RGW translates S3 requests into internal Rados requests and how OSD stores S3 objects and metadata in the case of Bluestore. Second, we will analyze S3 performance with and without versioning-related features on three different S3-compatible storage platforms: Ceph, MinIO, and OpenStack Swift with Swift3. We conducted a synthetic benchmark to measure S3 performance, especially ListObject performance, while considering versioning-related features.
