Ceph has historically been challenged by transactional workloads requiring Iow latencies in the sub 10ms range. This has excluded Ceph RBD from a whole class of applications and limited its adoption in the enterprise. New technologies like RDMA, NVMe and 3D XPoint have emerged in the last few years that are having a significant impact on Ceph by enabling deterministic, low latency (sub 10ms) performance. In this talk we explore these technologies, demonstrating how they can be used in a Ceph Luminous Cluster to deliver groundbreaking performance, opening whole new classes of workloads to the Ceph ecosystem.
Attendees will expect to learn various approaches to configuring all-flash Ceph clusters to provide low latency and deterministic performance.
