The firmware takes several seconds to initialize.
During this time the adapter scans the ports.
Step 8
Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to
configure the physical arrays and the logical
drives. When the message
Press
<Ctrl><H> for
WebBIOS
appears on the screen, press CTRL+H
immediately to run the utility.
Note:
Refer to the
MegaRAID SAS Software User’s
Guide
on the
MegaRAID Universal Software

Step 9
Install the Operating System Driver
The SAS 8300XLP can operate under various
operating systems. To operate under these
operating systems, you must install the software
drivers.
The
MegaRAID Universal Software Suite
CD
includes software drivers for the supported
operating systems, along with documentation.
You can view the supported operating systems
and download the latest drivers for RAID
adapters on the LSI Logic web site at:
http://www.lsilogic.com/cm/DownloadSearch.do
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 details on
installing the driver. Be sure to use the latest
Service Packs provided by the operating system
manufacturer and to review the
readme
file that
accompanies the driver.

The SAS 8300XLP supports 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 hard drives.
•
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. Provides good data throughput for
applications with high read request rates.
•
RAID 10 (RAID 1 and RAID 0 in spanned arrays):
Uses
mirrored pairs of disks to provide complete data
redundancy. Provides high data throughput rates.
•
RAID 50 (RAID 5 and RAID 0 in spanned arrays):
Uses
both parity and disk striping across multiple disks to
provide complete data redundancy. Provides high data
throughput rates.
