Dell PowerEdge R730xd Performance and Sizing Guide for Red Hat Ceph Storage - A Dell Red Hat Technical White Paper 6

1 Introduction

Unstructured data has demanding storage requirements across the access, management, maintenance,

and particularly the scalability dimensions. To address these requirements, Red Hat Ceph Storage provides

native object-based data storage and enables support for object, block, and file storage.

Key takeaways of deploying Red Hat Ceph on Dell PowerEdge R730xd servers

The Red Hat Ceph Storage environment makes use of industry standard servers that form Ceph nodes for

scalability, fault-tolerance, and performance. Data protection methods play a vital role in deciding the total

cost of ownership (TCO) of a solution. Ceph allows the user to set different data protection methods on

different storage pools.

 Replicated storage pools make full copies of stored objects, and is ideal for quick recovery. In a

replicated storage pool, the Ceph configuration defaults to a replication factor of three, where

three copies of the data are placed on three separate Ceph nodes.

 Erasure-coded storage pools provide a single copy of data plus parity, and it is useful for archive

storage and cost-effective durability and availability. For more information on designing scalable

workload-optimized Ceph clusters, please see the configuration guide at
