1.2 Introduction on RAID Basic Knowledge
RAID, an acronym for Redundant Arrays of Independent Disk, is a cheap redundant disk array. RAID
falls into soft array and hard array. Soft array is achieved through software, which needs computer
processor to provide computing capacity and only basic RAID fault tolerance functions are available.
Hard array means that separate hard ware, RAID card for example, provides control and computing
functions of whole disk arrays. Separate processor is available on RAID card, independent of system
CPU resource. All necessary fault tolerance functions are available for hard RAID, so it can provide
better functions and performance than soft array.
SAS RAID 2108 card supports RAID 0, 1, 5, 6, 10, 50, 60, Simple Volume and JBOD. It also
supports multiple Stripe Size settings. Here we give a brief introduction on RAID levels
characteristics.
RAID level- RAID 0
1. Characteristics: Data is transferred among over two disk drives, parallel with I/O system to improve
I/O performance. If n represents the number of disks, each disk drive stores one nth of data.
2. Application: Relatively higher read and write performance, but the data is not redundant. RAID0
itself is only suitable for the applications that have fault tolerance for data access and data that can be
5
rebuilt in other approaches.
RAID level – RAID1
1. Characteristics: Disk image is supported, which can protect data and improve data read
performance. RAID1 can build data image in over two disks, which are very similar. RAID1 adopts
n plus n protection mode, so double number of disks is required.
2. Application: It enjoys relatively high performance and reliability in reading operation-intensive
OLTP and other transaction data. Other applications also benefit from RAID1, for example, e-mail,
operating system, application files and random access environment.
RAID level - RAID0+1
1. Characteristics: Data stripe and image are available, and n plus n drives are used, enjoying higher
stripe performance and image reliability. In case of one disk drive fault, performance and reliability
will not be affected. But in RAID0, drive fault will affect performance and reliability. Furthermore,
disk stripe technology will improve performance.
2. Application: OLTP and I/O intensive application ask for high performance and reliability, including
transaction log, log file, data index etc. The total cost is calculated based on each I/O operation, rather
than each storage unit cost.
RAID level - RAID1+0(RAID10)
1. Characteristics: Similar to RAID0+1, data stripe and image are available, and n + n drives are used,
enjoying higher stripe performance and image reliability. RAID10 differs from RAID0+1 in achieving
image functions following centralized stripe of all disks.
2. Application: OLTP and I/O intensive applications necessitate high performance and reliability,
including transaction log, log file, data index etc. The total cost is calculated based on each I/O
operation, rather than each storage unit cost.
RAID level – RAID5
1. Characteristics: Disk stripe and floating parity protection mode are provided in n+1 mode,
providing high reliability for most users and I/O stream concurrent operation and enjoying high read
performance. Vacant disk drives can be used to rebuild data (disk rebuild), so as to prevent data
from re-destroying after disk rebuild.
2. Application: Reduce the number of necessary disks and provide good reliability and read
performance. If write cache is not used, write performance will be affected to some extent.
Applications RAID5 suits including relational data, read-intensive database form, file sharing and
web application.
RAID level – RAID6
1. Characteristics: Disk stripe and floating parity are provided in double parity mode, which are
designed to minimize the influence on data reliability during disk rebuilding, especially when using
high-capacity fiber channel and SATA disk drives. The problem for RAID6 and other multiple-drive
parity mode lies in that parity is necessary when writing data or rebuilding fault disk drives, when
performance will be affected.
2. Application: In general, if you want to achieve high performances read and write operations; using
6
small disk drive is feasible, avoiding using RAID6. On the other hand, if you want to store mass data,
but storage position may be rebuilt. Proper configuration of RAID5 and RAID6 can meet application
requirement.

1.3 Introduction on Essential Terms of RAID
1. Battery backup: Normally, it is optional, which provides data protection for RAID cache after
power failure in some special applications. Generally, it can only protect data security for cache
within 72 hours after power failure. Once the system restores, cache data will be re-written to hard
disks or other storage system. As battery has a limited life, it is required to replace a new one when it
is charged for about 1100 times.
2. Hot fix (hot spare) disks: Hot fix disk can automatically replace the failed disk having matched
capacity and the array starts rebuilding action in case where one or two disks in array failed.
Notes: Be sure that the capacity of hot fix disk is equal to or more capacious than the largest disk
to be protected.
3. Array Roaming compatibility: It allows complete RAID array transfer from one server system
to another and ensures the completeness of data and configuration information. Array roaming is
based on the premise of compatibility between RAID controllers for two systems, that is, RAID
configuration information written into disks shares the same data format. The feature also allows
replacing another compatible one in case of a RAID card on server failed, to prevent data in disk array
from losing.
4. Array level migration: As data application changes in user storage array, it is possible to bring
the performance of array into full play only by changing RAID level, when RAID level migration is
required. Different array level migration is supported depending on RAID cards we provided,
generally, only migration among RAID0, RAID1 and RAID5 can be supported and data completeness
can be ensured.
5. Initialize background: RAID card supports operating system installation and other operations
during building disks array through background initialization. Of course, you can install operating
system after the initialization, and the installation will be more quickly in this way.
6. Online capacity expansion without reboot (OCE): It allows adding new physical drives to the
array that is configured and completes build task, to achieve capacity expansion on the server without
supporting reboot. For some of RAID cards we provided, the OCE function can only achieve online
capacity expansion for part of RAID levels like RAID0, RAID5 AND RAID10 in Windows 2000, NT
and NetWare operating systems, while server reboot is required in other operating systems. It is
estimated that storage demand will go up at the rate of 30 percent annually. The features of OCE can
gradually satisfy users’ growing demand on storage in several steps, and lay foundation for policy
formulation.
7. Auto rebuild: When a disk failed, the system will automatically enable hot spare disk or detect
a new disk that is inserted to the same ID location and has a capacity larger than or equal to the failed
one. Then the system will automatically start rebuild operation.

drive on the screen shown in figure 4-19.
39
5. If it is unnecessary to modify properties of virtual drives, default properties will be displayed on
the screen.
Here we give a brief introduction on options of virtual drive:
RAID Level: Pull-down menu lists RAID levels that virtual drive can create.
Strip Size: Stripe size specifies a size of strip to write in RAID configuration. Available strip sizes are
8, 16, 32, 64 and 128 kilobytes. A large strip size will improve read performance significantly. If
computer performs random access request regularly, it is recommended to select a small strip size.
Access Policy: Select a data access type allowed by virtual drive. Available options are Read/Write,
Read Only and Blocked.
Read Policy: Specify a read policy for disk array. Available options:
Ahead: This option has read-ahead capacity, allowing controller to read-ahead requested data to
memory through estimating data to be used. It will improve the speed of continuous data reading, but
impose little impact on random data access.
Normal: Selecting this option will close Read Ahead function.
Adaptive: When proper read-ahead is selected, controller will first adopt Read Ahead. If the last two
disk accesses occur in continuous sectors, but read request is random, the controller will return to
Normal status (non-read-ahead).
Write Policy: Specify read policy of virtual drives.
Wback: write back. In write back mode, controller will send a transmission completion signal to
host when the controller has processed received data. This option is recommended as standard
mode.
Wthru: In Writethrough mode, controller will send a data transmission completion signal to host
when disk sub system has received all data transmitted.
Bad BBU: Select this mode when controller has no BBU or BBU has failed, but you need controller
to use Writeback mode. If this mode is not selected, controller’s Firmware will automatically shift to
Writethrough mode when the controller detects BBU failure or can’t detect BBU.
IO Policy:IO policy is suitable for reading special virtual drive. It imposes no impact on reading
ahead cache.
Drive Cache: drive cache policy option. Available status: open, close and unchanged.
Disable BGI: Select [No] to allow opening background initialization, which means that a new
configuration can be initialized in background mode during performing other configuration task using
WebBIOS. Select [Yes] to disable background initialization.
Select size: Specify capacity of virtual drive in Megabyte. Normally, it is recommended to select the
40
maximum size listed on the right panel of configuration screen. If you want to make several virtual
drives in one disk array, it is advisable to specify a relatively small size.
6. Click [Accept] to accept changes on virtual drives, or click [Reclaim] to go back to previous
settings.
7. Click [Next] upon completion of all virtual drive definitions, and the following screen appears:
