Integrated Striping

This chapter provides an overview of the LSI Integrated Striping™ (IS) feature and 
explains how to create Integrated Striping (IS) volumes using the SAS2 BIOS 
Configuration Utility, which is used to setup IR Mode.

Introduction

Integrated RAID enables you to create Integrated Striping volumes for applications that 
require the faster performance and increased storage capacity of striping. The low-cost 
Integrated Striping feature has many of the advantages of a more expensive RAID 
striping solution. You can configure an Integrated Striping volume as the boot disk or as 
a data disk.

The Integrated Striping solution provides better performance and more capacity than 
individual disks, without burdening the host CPU. The firmware splits host I/Os over 
multiple disks and presents the disks as a single logical drive. In general, striping is 
transparent to the BIOS, the drivers, and the operating system.

You use the SAS2 BIOS Configuration Utility to configure Integrated Striping volumes. 
These volumes can consist of two-to-ten disks.

NOTE: 

Integrated Striping is also known as RAID 10.
