Dell PowerEdge R730xd Performance and Sizing Guide for Red Hat Ceph Storage - A Dell Red Hat Technical White Paper 35
5 Dell Server Recommendations for Ceph
Ceph operators frequently request simple, optimized cluster configurations for different workload types.
Common requests are for throughput-optimized and capacity-optimized workloads. IOPS-intensive
workloads on Ceph are also emerging. Based on extensive testing by Red Hat and Dell on various Dell
PowerEdge server configurations, this matrix provides general guidance on sizing Ceph clusters built on
Dell PowerEdge servers.
