Choosing a RAID Policy

When selecting a RAID policy, you should consider the level of data protection you require, as well as I/O performance, capacity

needs, and the types of drives contained in your PS Series array. Table 106. RAID Policies summarizes best practices for RAID policy

selection.

Table 106. RAID Policies

RAID Policy Recommended Usage Scenarios Recommended Drive Conguration

RAID 10 Applications and workloads requiring the highest

levels of I/O performance for random writes

Systems containing 10K and 15 K RPM drives

RAID 6 Applications requiring the highest levels of data

protection and reliability. Situations in which I/O

performance for random writes is not a key factor.

Systems containing 7200 RPM SATA or Nearline

SAS (NL-SAS) drives. Systems containing 24 or

more drives.

RAID 6 Accelerated Optimizes the use of solid-state drives for critical

data

Supported only on arrays that contain both solid

state (SSD) and hard disk (HDD) drives. For these

systems, it is the only available RAID policy. It is not

a user-selectable option.

RAID 50 Applications requiring an optimal combination of

performance, availability, and capacity

NOTE: You cannot select RAID 50 for

PS6610 arrays from the GUI. Instead, you

must use the CLI command member select

raid-policy. See the

Dell EqualLogic Group

Manager CLI Reference Guide

for more

information.

Systems containing fewer than 24 drives. Systems

containing 10K and 15K RPM drives.

RAID 5 Dell recommends not using RAID 5 for any

business-critical data. RAID 5 carries higher risks

of encountering an uncorrectable drive error during

a rebuild, and therefore does not oer optimal data

protection. RAID 5 can only be congured using

the CLI.

None.

For more information about RAID policies on PS Series systems, review the Dell Technical Report entitled PS Series Storage Arrays:

Choosing a Member RAID Policy, which you can download from the following location:

http://en.community.dell.com/dell-groups/dtcmedia/m/mediagallery/19861480

Table 107. RAID Level Characteristic Comparison compares the performance of the supported RAID levels for dierent workload

requirements.

Table 107. RAID Level Characteristic Comparison

Workload Requirement RAID 5 RAID 6 RAID 10 RAID 50

Capacity Excellent Good Fair Good

Data availability Poor Best Excellent Fair

Sequential reads Excellent Excellent Excellent Excellent

Sequential writes Good Good Good Good
