1.3RAID Concepts
RAID Fundamentals
The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple
inexpensive disk drives into an array of disk drives to obtain performance, capacity and
reliability that exceeds that of a single large drive. The array of drives appears to the host
computer as a single logical drive.
Five types of array architectures, RAID 1 through RAID 5, were originally defined; each
provides disk fault-tolerance with different compromises in features and performance. In
addition to these five redundant array architectures, it has become popular to refer to a
non-redundant array of disk drives as a RAID 0 arrays.
Disk Striping
Fundamental to RAID technology is striping. This is a method of combining multiple drives
into one logical storage unit. Striping partitions the storage space of each drive into stripes,
which can be as small as one sector (512 bytes) or as large as several megabytes. These
stripes are then interleaved in a rotating sequence, so that the combined space is
composed alternately of stripes from each drive. The specific type of operating
environment determines whether large or small stripes should be used.
Most operating systems today support concurrent disk I/O operations across multiple
drives. However, in order to maximize throughput for the disk subsystem, the I/O load
must be balanced across all the drives so that each drive can be kept busy as much as
possible. In a multiple drive system without striping, the disk I/O load is never perfectly
balanced. Some drives will contain data files that are frequently accessed and some drives
will rarely be accessed.
By striping the drives in the array with stripes large enough so that each record falls
entirely within one stripe, most records can be evenly distributed across all drives. This
keeps all drives in the array busy during heavy load situations. This situation allows all

User’s Manual
drives to work concurrently on different I/O operations, and thus maximize the number of
simultaneous I/O operations that can be performed by the array.
Definition of RAID Levels
RAID 0 is typically defined as a group of striped disk drives without parity or data
redundancy. RAID 0 arrays can be configured with large stripes for multi-user
environments or small stripes for single-user systems that access long sequential records.
RAID 0 arrays deliver the best data storage efficiency and performance of any array type.
The disadvantage is that if one drive in a RAID 0 array fails, the entire array fails.
RAID 1, also known as disk mirroring, is simply a pair of disk drives that store duplicate
data but appear to the computer as a single drive. Although striping is not used within a
single mirrored drive pair, multiple RAID 1 arrays can be striped together to create a single
large array consisting of pairs of mirrored drives. All writes must go to both drives of a
mirrored pair so that the information on the drives is kept identical. However, each
individual drive can perform simultaneous, independent read operations. Mirroring thus
doubles the read performance of a single non-mirrored drive and while the write
performance is unchanged. RAID 1 delivers the best performance of any redundant array
type. In addition, there is less performance degradation during drive failure than in RAID
5 arrays.

NAS System
User’s Manual

Under RAID 5 parity information is distributed across all the drives. Since there is no
dedicated parity drive, all drives contain data and read operations can be overlapped on
every drive in the array. Write operations will typically access one data drive and one
parity drive. However, because different records store their parity on different drives, write
operations can usually be overlapped.
RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity information
to the physical drives in the array. With RAID 6, however, two sets of parity data are used.
These two sets are different, and each set occupies a capacity equivalent to that of one of
the constituent drives. The main advantage of RAID 6 is High data availability –any two
drives can fail without loss of critical data.

NAS System
10
User’s Manual
Dual-level RAID achieves a balance between the increased data availability inherent in
RAID 1 and RAID 5 and the increased read performance inherent in disk striping (RAID 0).
These arrays are sometimes referred to as RAID 0+1 or RAID 10 and RAID 0+5 or RAID
50.
In summary:
RAID 0 is the fastest and most efficient array type but offers no fault-tolerance. RAID
0 requires a minimum of two drives.
RAID 1 is the best choice for performance-critical, fault-tolerant environments. RAID
1 is the only choice for fault-tolerance if no more than two drives are used.
RAID 5 combines efficient, fault-tolerant data storage with good performance
characteristics. However, write performance and performance during drive failure is
slower than with RAID 1. Rebuild operations also require more time than with RAID 1
because parity information is also reconstructed. At least three drives are required for
RAID 5 arrays.
RAID 6 is essentially an extension of RAID level 5 which allows for additional fault
tolerance by using a second independent distributed parity scheme (two-dimensional
parity). Data is striped on a block level across a set of drives, just like in RAID 5, and
a second set of parity is calculated and written across all the drives; RAID 6 provides
for an extremely high data fault tolerance and can sustain multiple simultaneous drive
failures. It is a perfect solution for mission critical applications.
1.4 Array Definition
1.4.1 Drive Group

NAS System
User’s Manual
11
A Drive Group is a group of physical drives attached to the RAID controller, and where
one or more Virtual Drives (VD) can be created. All Virtual Drives in the Drive Group use
all of the physical drives in the Drive Group.
It is not possible to have multiple Disk Groups on the same physical disks. If physical
disks of different capacity are grouped together in a Drive Group, then the capacity of
the smallest disk will become the effective capacity of all the disks in the Drive Group.
1.4.2 Virtual Drive
A Virtual Drive is seen by the operating system as a single drive or logical device. A
Virtual Drive is a storage unit created by the RAID controller from one or more physical
drives. If there is an existing Drive Group and there is available Free Space, then a new
Virtual Drive can still be created.
Depending on the RAID level used, the Virtual Drive may retain redundant data in
case of a drive failure.

Every Drive Carrier has 2 status indicator lights. The status indicator light is used for
Power On/Error. When this light is GREEN the power is on and everything is
functioning normally. When the Power On/Error light is RED, then an error has occur
that requires the user’s attention.
The activity indicator light is the hard disk drive access light. When the hard disk
drive is being accessed, this light will flash BLUE.
In addition, both indicator lights are viewable within a 170° arc.
