Ceph is an open source distributed object storage system designed to provide high performance, reliability, and massive scalability. Ceph implements object storage on a distributed computer cluster, and provides interfaces for object, block and file-level storage. Ceph provides for completely distributed operation without a single point of failure, scalability to the petabyte level, and replicates data for fault-tolerance. As a result of its design, the system is both self-healing and self-managing, helping to minimize administration time and other costs.
Red Hat Ceph Storage is an enterprise-ready implementation of Ceph that provides a single platform solution for software-defined storage that is open, adaptable, scalable, technologically advanced, and supported worldwide. Red Hat Ceph Storage combines innovation from the open source community with the backing of Red Hat engineering, consulting, and support. It includes tight integration with OpenStack services and was built from the ground up to deliver next-generation storage for cloud and emerging workloads.
This technical white paper provides performance and sizing guidelines for Red Hat Ceph Storage running on Dell servers, specifically the Dell PowerEdge R730xd server, based on extensive testing performed by Red Hat and Dell engineering teams. The PowerEdge R730xd is an award-winning server and storage platform that provides high capacity and scalability and offers an optimal balance of storage utilization, performance, and cost, along with optional in-server hybrid hard disk drive and solid state drive (HDD/SSD) storage configurations.
This paper is intended for storage architects, engineers, and IT administrators who want to explore the advantages of using Red Hat Ceph Storage on Dell PowerEdge servers and who need to design and plan implementations using proven best practices.
