2.1 Setting up RAID
The RAID card supports RAID 0, RAID 1, RAID 10, RAID 5, RAID 50, RAID 6, and
RAID 60 set(s).
2.1.1 RAID denitions
RAID 0
(Data striping)
data in parallel, interleaved stacks. Two hard disks perform the same work as a
single drive but at a sustained data transfer rate, double that of a single disk alone,
thus improving data access and storage. Use of at least two new identical hard
disk drives is required for this setup.
RAID 1
(Data mirroring)
drive to a second drive. If one drive fails, the disk array management software
directs all applications to the surviving drive as it contains a complete copy of
the data in the other drive. This RAID conguration provides data protection and
increases fault tolerance to the entire system. Use two new drives or use an
existing drive and a new drive for this setup. The new drive must be of the same
size or larger than the existing drive.
RAID 10 is a striped conguration with RAID 1 segments whose segments are
RAID 1 arrays. This conguration has the same fault tolerance as RAID 1, and
has the same overhead for fault-tolerance as mirroring alone. RAID 10 achieves
high input/output rates by striping RAID 1 segments. In some instances, a RAID
10 conguration can sustain multiple simultaneous drive failure. A minimum of four
hard disk drives is required for this setup.
RAID 5 stripes both data and parity information across three or more hard
disk drives. Among the advantages of RAID 5 conguration include better
HDD performance, fault tolerance, and higher storage capacity. The RAID
5 conguration is best suited for transaction processing, relational database
applications, enterprise resource planning, and other business systems. Use a
minimum of three identical hard disk drives for this setup.
RAID 50 is a combination of RAID 0 and RAID 5. It uses distributed parity and disk
striping and works best with data that requires high reliability, high request rates,
high data transfers, and medium-to-large capacity.
optimizes two identical hard disk drives to read and write
copies and maintains an identical image of data from one
Having RAID 0 and RAID 5 virtual disks in the same physical array is not
recommended. If a drive in the physical array has to be rebuilt, the RAID 0
virtual disk will cause a failure during the rebuild.
RAID 6 stripes dual parity to provide fault tolerance from two drive failures; array
continues to operate with up to two failed drives. This makes larger RAID groups
more practical, especially for high availability systems. With dual parity, RAID 6
gives time to rebuild the array without the data being volatile while the failed drive
is being recovered.
2-2Chapter 2: RAID conguration
RAID 60 is a combination of RAID 0 and RAID 6. It uses distributed parity, with two
independent parity blocks per stripe in each RAID set, and disk striping. A RAID
60 virtual disk can survive the loss of two disks in each of the RAID 6 sets without
losing data. It works best with data that requires high reliability, high request rates,
high data transfers, and medium-to-large capacity.
If you want to boot the system from a hard disk drive included in a created RAID
set, copy rst the RAID driver from the support CD to a oppy disk before you
install an operating system to the selected hard disk drive.
2.1.2 Installing hard disk drives
The RAID card supports SAS for RAID set conguration. For optimal performance,
install identical drives of the same model and capacity when creating a disk array.
To install SAS hard disks for RAID conguration:
1. Install the SAS hard disks into the drive bays following the instructions in the
system user guide.
2. Connect the SAS port connectors to the SAS drives.
ASUS PIKE 10782-3
2.2 LSI WebBIOS Conguration Utility
The LSI WebBIOS Conguration Utility (CU) is an integrated RAID solution that
allows you to create RAID 0, 1, 10, 5, 50, 6, and 60 set(s) from SAS hard disk
drives supported by the LSI SAS 1078 controller.
You can also use the WebBIOS CU to do the following tasks:
• Create physical arrays and virtual disks for storage congurations
• Delete virtual disks
• Migrate a storage conguration to a different RAID level
• Detect conguration mismatches
• Import a foreign conguration
• Display adapter, virtual disk, and physical drive properties.
• Scan devices connected to the controller
• Initialize virtual disks
• Check congurations for data consistency
• PIKE 1078 does not support the Battery Backup Unit (BBU) function.
• You may use disks of different sizes; however, the size of the smallest disk
determines the “logical” size of each member disk.
• DO NOT combine Serial ATA and SAS disk drives in one volume.
• The RAID setup screens shown in this section are for reference only and
may not exactly match the items on your screen due to the controller
version difference.
2.2.1 Starting the WebBIOS CU

2.2.3 Creating a Storage Conguration
This section explains how to use the WebBIOS CU Conguration Wizard to
congure RAID arrays and virtual disks.
Selecting the Conguration with the Conguration Wizard
Follow these steps to start the Conguration Wizard, and select a conguration
option and mode:
1. Click Conguration Wizard on
the WebBIOS main screen. The
rst Conguration Wizard screen
appears, as shown in the right
gure.
2. Select a conguration option.
If you choose the rst or second option, all existing data in the conguration will
be deleted. Make a backup of any data that you want to keep before choosing
these options.
• Clear Conguration: Clears the existing conguration.
• New Conguration: Clears the existing conguration and lets you
create a new conguration.
• Add Conguration: Retains the existing storage conguration and adds
new drives to it (this does not cause any data loss).
3. Click Next. A dialog box warns that you will lose data if you select Clear
Conguration or New Conguration.
4. On the next screen, select a conguration mode:
• Custom Conguration: Allows you to control all attributes of the new
storage conguration.
• Auto Conguration with Redundancy: Automatically creates an
optimal RAID 1 or RAID 5 conguration, providing data redundancy. We recommends that you select this option.
• Auto Conguration without Redundancy: Automatically creates a
non-redundant RAID 0 conguration.
5. Click Next to continue.
ASUS PIKE 10782-7
Using Auto Conguration
Follow these instructions to create a conguration with auto conguration, either
with or without redundancy:
1. When WebBIOS displays the proposed new conguration, review the
information on the screen, and click Accept to accept it. (Or click Back to go
back and change the conguration.)
• RAID 0: If you selected Auto Conguration without Redundancy,
WebBIOS creates a RAID 0 conguration.
• RAID 1: If you selected Auto Conguration with Redundancy,
WebBIOS creates a RAID 1 conguration if only two disk drives are available.
• RAID 5: If you selected Auto Conguration with Redundancy,
WebBIOS creates a RAID 5 conguration if three or more disk drives are available.
2. Click Yes when you are prompted to save the conguration.
3. Click Yes when you are prompted to initialize the new virtual disk(s).
WebBIOS CU begins a background initialization of the virtual disks.
Using Custom Conguration: RAID 0
RAID 0 provides disk striping across all drives in the RAID array. RAID 0 does not
provide any data redundancy but does offer the best performance of any RAID
level. RAID 0 is ideal for applications that require high bandwidth but do not require
fault tolerance. RAID 0 also denotes an independent or single drive.
RAID level 0 is not fault-tolerant. If a drive in a RAID 0 array fails, the whole
virtual disk (all physical drives associated with the virtual disk) fails.
When you select Custom Conguration and click Next, the Disk Group Denition
screen appears. You use this screen to select physical drives to create disk groups
(arrays).
1. Hold <Ctrl> while selecting two or
more ready drives in the Physical
Drives window on the left until you
have selected all desired physical
drives for the disk group.
2. Click Accept DG to move the
drives to a proposed disk group
conguration in the Disk Groups
window on the right, as shown in
the right gure.
If you need to undo the changes, click the Back button.
2-8Chapter 2: RAID conguration
3. When you have nished selecting
physical disks for the disk groups,
click Next.
The span denition screen appears
Select one of the available disk
groups, and then click Add to Span.
4. When nish, click Next. The Virtual
Disk Denition screen appears,
as shown in the right gure. You
use this screen to select the RAID level, strip size, read policy, and other
attributes for the new virtual disks.
5. Change the virtual disk options from the defaults listed on the screen as
needed.
Here are brief explanations of the virtual disk options:
• RAID Level: The drop-down menu lists the possible RAID levels for the
virtual disk. Select RAID 0.
• Strip Size: The strip size species the size of the segment written to
each disk in a RAID conguration. You can set the strip size to 8, 16, 32,
64, 128, 256, 512 or 1024 Kbytes. A larger strip size produces higher
read performance. If your computer regularly performs random read
requests, choose a smaller strip size. The default is 64 Kbytes.
• Access Policy: Select the type of data access that is allowed for this
virtual disk:
◊ RW: Allow read/write access. This is the default.
◊ Read Only: Allow read-only access.
◊ Blocked: Do not allow access.
• Read Policy: Specify the read policy for this virtual drive:
◊ Normal: This disables the read ahead capability. This is the default.
◊ Ahead: This enables read ahead capability, which allows the controller
to read sequentially ahead of requested data and to store the additional
data in cache memory, anticipating that the data will be needed soon.
This speeds up reads for sequential data, but there is little improvement
when accessing random data.
◊ Adaptive: When Adaptive read ahead is selected, the controller
begins using read ahead if the two most recent disk accesses occurred
in sequential sectors. If the read requests are random, the controller
reverts to Normal (no read ahead).
ASUS PIKE 10782-9
• Write Policy: Specify the write policy for this virtual drive:
◊ WBack: In Writeback mode the controller sends a data transfer
completion signal to the host when the controller cache has received
all the data in a transaction. This setting is recommended in Standard
mode.
◊ WThru: In Writethrough mode the controller sends a data transfer
completion signal to the host when the disk subsystem has received all
the data in a transaction. This is the default.
◊ Wrthru for BAD BBU: Select WBack for Write Policy and unselect this
item if you want the controller to use Writeback mode but the controller
has no BBU or the BBU is bad. If you choose this option, the controller
rmware automatically switches to Writethrough mode if it detects a bad
or missing BBU.
• IO Policy: The IO Policy applies to reads on a specic virtual disk. It
does not affect the read ahead cache.
◊ Direct: In direct I/O mode, reads are not buffered in cache memory.
Data is transferred to the cache and the host concurrently. If the same
data block is read again, it comes from cache memory. This is the
default.
◊ Cached: In cached I/O mode, all reads are buffered in cache memory.
• Disk Cache Policy: Specify the disk cache policy:
◊ Enable: Enable the disk cache.
◊ Disable: Disable the disk cache. This is the default.
◊ NoChange: Leave the current disk cache policy unchanged.
• Disable BGI: Specify the background initialization status:
◊ No: Leave background initialization enabled. This means that a
new conguration can be initialized in the background while you use
WebBIOS to do other conguration tasks. This is the default.
◊ Yes: Select Yes if you do not want to allow background initializations
for congurations on this controller.
• Select Size: Specify the size of the virtual disk in megabytes. Normally,
this would be the full size for RAID 0 shown in the Conguration Panel
on the right. You may specify a smaller size if you want to create other
virtual disks on the same disk group.
6. Click Accept to accept the changes to the virtual disk denition, or click Back
to return to the previous settings.
7. Click Next when you are nished dening virtual disks. The conguration
preview screen appears, as shown in the following gure.
