Install the Operating System Driver
The RAID controller can operate under various
operating systems, but you must install the
software drivers first.
The MegaRAID Universal Software Suite CD
includes software drivers for the supported
operating systems, along with documentation.
You can view the supported operating systems
on and download the latest drivers for RAID
adapters from the LSI web site at:
. Access the
download center, and follow the steps to
download the driver.
Refer to the MegaRAID SAS Device Driver
Installation User’s Guide on the MegaRAID
Universal Software Suite CD for more information
about installing the driver.
Be sure to use the latest service packs that are
provided by the operating system manufacturer
and to review the readme file that accompanies
the driver.

The SAS 8204ELP RAID Controller and the SAS 8208ELP
RAID Controller support disk arrays using the following RAID
levels:
• RAID 0 (data striping): Data is striped across all disks in
the array, enabling very fast data throughput. There is no
data redundancy. All data is lost if any disk fails.
• RAID 1 (disk mirroring): Data is written simultaneously
to two disks, providing complete data redundancy if one
disk fails. The maximum array capacity is equal to the
available size of the smaller of the two physical disks.
• RAID 5 (disk striping with distributed parity): Data is
striped across all disks in the array. Part of the capacity
of each disk stores parity information that reconstructs
data if a disk fails. RAID 5 provides good data throughput
for applications with high read request rates.
• RAID 10 (RAID 1 and RAID 0 in spanned arrays): RAID
10 uses mirrored pairs of disks to provide complete data
redundancy. RAID 10 provides high data throughput
rates.
