Dell PowerEdge R730xd Performance and Sizing Guide for Red Hat Ceph Storage - A Dell Red Hat Technical White Paper 31
4.2 Comparing Overall Solution Price/Performance
Based on the highest measured write price/performance, the R730xd 16+1, 3xRep configuration yielded
optimal price performance for mixed read/write, and throughput-oriented workloads. However, for read-
mostly workloads, the R730xd 12+3, 3xRep configuration is an attractive alternative based on its superior
read price/performance.
Total solution price/Mbps (4 MB sequential read/write)
Note: On the basis of data protection scheme selected and the average selling price (ASP) of the Red Hat
Ceph Storage subscription for the raw storage capacity (TB) required:
The Cluster Server plus software cost is equal to ASP of servers required to provide 500 TB of usable
capacity (based on the data protection scheme chosen), and the ASP of Red Hat Ceph Storage
subscription ASP for the terabytes required.
