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 benets.
The LSI Logic Integrated RAID solution provides cost benets for the server or work-
station market where the extra performance, storage capacity, and/or redundancy of a
RAID conguration are required. The two components of Integrated RAID are:
Integrated Mirroring (IM), which provides features of RAID 1 and RAID 1E (RAID 1
Enhanced). RAID 1E is also called Integrated Mirroring Enhanced (IME)
Integrated Striping (IS), which provides features of RAID 0
By simplifying the IM and IS conguration options and by providing rmware support in
its host adapters, LSI Logic can offer the Integrated RAID solution at a lower cost than
a hardware RAID implementation.
Fusion-MPT™ rmware supports IM and IS volumes. You can congure IM and IS vol-
umes together on the same LSI Logic SAS controller.
Integrated RAID Benets and Features
Low cost RAID volume creation meets the needs of most internal RAID installa-
tions
Easy to use - installation and conguration are not complex
System can boot from an IM, IME, or IS volume
No special OS-specic software required
High reliability and data integrity
- Non-volatile write journaling
- Physical disks not visible to OS or to application software
Low host CPU and PCI bus utilization
Fusion-MPT architecture provides processing power
- Shared memory architecture minimizes external memory requests
- Functionality is contained in device hardware and rmware
