Chapter 2 RAID
This chapter describes the RAID features that the disk array controller supports.
1. Overview of RAID
1-1 What is RAID (Redundant Array of Inexpensive Disks)?
RAID is an abbreviation for "Redundant Array of Inexpensive Disks." RAID technology allows more than one
HDD to be handled collectively.
RAID configures multiple HDD‟s as a single array (disk group) to operate the HDD‟s more effectively. This
can provide higher performance than a single, large capacity HDD.
This disk array controller has a feature to divide a single disk group into several logical drives. The host
computer recognizes these virtual disks as if they were a single HDD. The host computer accesses more
than one HDD when configuring a disk group in parallel.
Some RAID levels can recover data from remaining data and parity by using a rebuild feature if an error
occurs on a single HDD. This can provide high reliability for the system.
1-2 RAID Levels
The disk array controller supports the following RAID levels: RAID 0 and RAID 1. The number of HDD‟s
required to create a disk group varies depending on the RAID level as shown in the table below:

HDD 0
(36 GB)

1-3 Disk Group
A disk group is configured with more than one HDD.
Up to two disk groups are permitted by the disk array controller when two HDD‟s are installed in the server.
The figure below shows a sample configuration. Two HDD‟s are connected to the disk array controller,
creating one disk group (DG).
1-4 Virtual Disk
A virtual disk is a logical drive defined in a disk group. It is recognized as a physical drive by the OS. Up to 40
virtual disks are permitted by the disk array controller.
The figure below shows a sample configuration in which the disk array controller is connected to two HDD‟s,
creating one disk group (DG). Two RAID1 virtual disks (VD) are defined in the DG.
1-5 Hot-Swap
The hot-swap feature enables a HDD to be removed (or replaced) during system operation.

2-1 Characteristics of RAID Levels
The table below lists the characteristics of the RAID levels:
2-2 RAID0
73
In RAID 0, data is distributed between HDD‟s. This mode is called "striping."
In the figure below, data is recorded in stripe 1 (disk 0) and stripe 2 (disk 1). Because RAID0 allows HDD‟s to
be accessed collectively, it can provide the best disk access performance.
74

2-3 RAID1
In RAID1, data saved to a HDD is written to another HDD without change. This mode is called "mirroring."
When data is written to a single HDD, the same data is written to another HDD. If either of the HDD‟s fails,
the other HDD containing the same data can substitute for the failed HDD. Thus, the system can continue to
operate without interruption.
Chapter 3 Features of Disk Array
Notice
Note the following for the rebuild:
The HDD used for rebuild should have the same capacity, rotation speed, and
standard as the failed HDD.
During rebuild, the responsiveness of the server decreases due to high load.
During rebuild, do not shutdown or reboot the server. If the server is shutdown
accidentally due to power interruption, turn on the power as soon as possible. The
rebuild is automatically restarted.
The interval from the removal of the failed HDD to the installation of a new HDD
should be 60 sec or longer.
If the hot-swap rebuild does not work, perform the manual rebuild.
When the failed HDD is removed in a RAID1 configuration, the data redundancy is
lost. Replace with a new HDD as soon as possible and perform the rebuild process.
Controller
This chapter describes the features of the disk array controller.
1. Rebuild
If a HDD fails, the rebuild feature can recover the data on the failed HDD. The access lamp on the failed
HDD lights amber. The rebuild can be applied to redundant virtual disks in RAID1 after the failed HDD is
replaced. While rebuilding, the access lamp on the replaced HDD flashes.
75
1-1 Manual Rebuild
The manual rebuild can be performed by using MegaRAID Storage Manager
is the management utility of the disk array controller. Select a HDD and start the rebuild manually.
For the detailed operation, refer to the "MegaRAID Storage Manager User's Guide" on the NEC
EXPRESSBUILDER CD-ROM that comes with the server.
TM
(called MSM hereafter), which
1-2 Auto Rebuild
The disk array controller can automatically start the rebuild without using a utility such as MSM.
The auto rebuild includes:
Hot-swap rebuild
When the failed HDD is hot-swapped with a new HDD, the auto rebuild is automatically performed.
76
Notice
Note the following for the patrol read:
The patrol read feature is factory-set to "Disabled."
To utilize patrol read, MSM must be installed.
If the system is restarted, the patrol read is aborted. After restart of the
system, the patrol read runs from the first step (top of HDD).
For the detailed operation, refer to the "MegaRAID Storage Manager
User‟s Guide" on the NEC EXPRESSBUILDER CD-ROM that comes
with the server.
Notice
Note the following for the consistency check:
During the consistency check, the responsiveness of the server
decreases due to high load.
If the system is restarted, the consistency check is aborted. However,
the consistency check resumes after restart.
For the detailed operation, refer to the "MegaRAID Storage Manager
User‟s Guide" on the NEC EXPRESSBUILDER CD-ROM that comes
with the server.
2. Patrol Read
Patrol read performs a read & verify test on the entire area of the HDD. It can be performed for all HDD‟s
assigned to virtual disks and hot-spare disks.
Patrol read allows defects of the HDD‟s to be detected and repaired.
For HDD‟s configuring redundant virtual disks or those assigned to hot-spare disks, error sectors detected
during patrol read can be repaired.
3. Consistency Check
Consistency check is used to check the consistency among virtual drives. It is available for redundant virtual
drives in RAID1.
Consistency check can be performed through WebBIOS or MSM.
Consistency check also repairs error sectors. Accordingly, it can be used for preventive maintenance.

Note the following for the reconstruction:
Be sure to make a backup copy of data before starting reconstruction.
Reconstruction is disabled in a configuration where several virtual disks are defined in
one disk group
During reconstruction, the responsiveness of the server decreases due to high load.
Reconstruction is disabled for a degraded virtual disk. First, execute rebuild to recover
the virtual disk, and then execute reconstruction.
During reconstruction, do not shutdown or reboot the server. If the server is shutdown
accidentally due to power interruption, turn on the power as soon as possible.
Reconstruction is automatically restarted.
The reconstruction feature is used to change the configuration and/or RAID level of an existing virtual disk.
Reconstruction contains the following three features; however, the disk array controller supports "Migration
with addition" only.
