5 Understanding RAID with Dell SC Series Storage | 3104-CD-DS
Executive summary
Dell™ SC Series storage is designed to take advantage of redundant components, including RAID, in order to
achieve the greatest level of performance and availability. Core to the SC Series Fluid Data™ Architecture is
the automatic placement of data across the available disks. The disks are logically grouped by type based on
speed and capacity. RAID protection is built on a page architecture that provides data optimization for
availability, capacity, and performance. SC Series arrays automate the most efficient data placement. From a
performance and availability perspective, all applications write to the highest performing RAID level and disks.
As time passes, data with lower activity moves to capacity efficient RAID levels and disk types.
This document provides a general understanding of how RAID is used in SC Series arrays, RAID levels and
disk tier usage, as well as large SSD considerations and appropriate selection of data protection based on
performance, availability, and efficiency.
