You intend to manage any of the attached SAS devices.
5.1.1 Introduction to Integrated RAID
This section provides an overview of the LSI Logic Integrated RAID solution for LSI Logic SAS controllers, its
features, and its benefits.
The LSI Logic Integrated RAID solution provides cost benefits for the server or workstation market where the
extra performance, storage capacity, and/or redundancy of a RAID configuration are required.
z
Integrated Mirroring (IM), which provides features of RAID 1 and RAID 1E (RAID 1 Enhanced).
RAID 1E is also called Integrated Mirroring Enhanced (IME).
z
Integrated Striping (IS), which provides features of RAID 0.
By simplifying the IM and IS configuration options and by providing firmware support in its host adapters, LSI
Logic can offer the Integrated RAID solution at a lower cost than a hardware RAID implementation.
Fusion-MPT™ firmware supports IM and IS volumes. You can configure IM and IS volumes together on the same
LSI Logic SAS controller.
Integrated RAID Benefits and Features
z
Low cost RAID volume creation meets the needs of most internal RAID installations
z
Easy to use - installation and configuration are not complex
z
System can boot from an IM, IME, or IS volume
