1.3 FEATURES
1.3.1 DATA SECURITY
The DAS401 software driver includes support for monitoring to predict suspect drives.
DAS401 provides our highest commitment to data security through the use of RAID architecture to back up and
protect data. RAID levels 1, 10, and 5 provide data security. DAS401 supports sophisticated sparing support so that
hardware failure risk can be minimized by automatically regenerating the
failed disk’s data on a backup disk. The DAS401 software driver includes support for Self- Monitoring
Analysis and Reporting Technology (S.M.A.R.T.
2
) to predict disk failures. Drives can be moved between
controllers without losing data.

1.3.2 DATA PERFORMANCE
The DAS401 can also increase storage throughput by combining the throughput of multiple drives into a single
volume. RAID levels 1, 10, and 5 support this ability. Furthermore, each volume can be tailored to provide the best
performance for the data contained on that disk.
1.3.3 DATA VERSATILITY
The DAS401 software driver also supports Contiguous and Concatenated drives for applications which do not
require increased security or performance.
1.4 EASE OF USE
The DAS401 utility offers an easy to use utility for creating and managing your storage. It also supports the latest
SATA enhancements including SATA-II Port Multiplier support, and up to 3Gbit/sec transfer rates on controllers
that support that speed. Creating and deleting volumes is also possible without requiring a restart of the operating
system and rebuilds never require the data to be taken off-line.
Drives can also be moved between controllers without losing the data.

2 AN INTRODUCTION TO RAID
2.1 RAID VOLUMES
RAID technology allows one or more disks to be combined into a logical volume which provides greater
performance and/or protection than standard disk drives. These volumes, also known as RAID Groups, appear
like regular disk drives to the operating system and can be partitioned, formatted and used just like any other
normal disk. The complexity of the RAID is hidden within the driver.
There are several different methods of combining disks, each with its own advantages and disadvantages. Each
method is referred to as a RAID “level” such as RAID 1, or RAID 5. The details of each level are summarized
below and detailed in the following sections.
RAID LEVEL
CONFIGURED AS ADVANTAGES
DISADVANTAGES
0 Striped Excellent performance, low cost No data protection
1 Mirrored Excellent data protection High cost
10 Mirrored Striped High performance, excellent data
protection.
High cost.
5 Parity RAID Good data protection, good value Some performance degradation
for writes.
Combination Concatenated Good performance, low cost, large
Volume size
No data protection
Single Drive / Segment Contiguous Same as single disk Same as single disk
2.2 SEGMENTING DISKS
For increased versatility, the SATARAID5 software allows individual disks to be divided into smaller segments
which can then be combined into different volumes. As an example, if a user has one set of data that must
be protected at all costs, another set of data which should be protected at reasonable cost and another set
that
doesn’t need any protection at all; the user can divide three disks into sections as shown in Figure 1. The yellow
regions define the high security v olu me, the greem section is the middle security volume and the light blue shows
the unprotected area.

2.3 RAID LEVELS
2.3.1 DISK STRIPING (RAID 0)
Striping is a performance-oriented, non-redundant data mapping technique. While Striping is discussed as a
RAID Group type, it is does not provide any fault tolerance. With modern SATA and ATA bus mastering
technology, multiple I/O operations can be performed in parallel, enhancing data throughput. Striping arrays use
multiple disks to form a larger virtual disk. The figure below illustrates a three-disk stripe set. Stripe one is written
to disk one, stripe two to disk two, and so forth. RAID 0 sets can be comprised of two, three, or four drives. If the
sizes of the disk segments are different, the smallest disk segment will limit the overall size of the RAID Group.
Stripe0 Stripe1 Stripe2
Stripe3 Stripe4 Stripe5
Stripe6
Stripe9
Stripe7
Stripe10
Stripe8
Stripe11
2.3.2 DISK MIRRORING (RAID 1)
Disk mirroring creates an identical twin for a selected disk by having the data simultaneously written to two disks.
This redundancy provides instantaneous protection from a single disk failure. If a read failure occurs on one drive,
the system reads the data from the other drive. RAID 1 sets are comprised of two drives, and a third drive can be
allocated as a spare in case one of the drives in the set fails. If the sizes of the disk segments are different, the
smallest disk segment will limit the overall size of the RAID Group.

2.3.3 DISK MIRRORING AND STRIPING (RAID 10)
RAID 10 combines the features of both RAID 0 and RAID 1. Performance is provided through the use of Striping
(RAID 0), while adding the fault tolerance of Mirroring (RAID 1). The implementation of RAID 10 requires four
drives. The drives are assigned as two sets of striped pairs.
The data is written to RAID Group A, which is mirrored (RAID 1) a nd provides data redundancy. Alternating
blocks of data are then striped across another RAID 1 mirrored set, shown as Set B in the figure above. This
provides improved speed.
Under certain circumstances, a RAID 10 set can sustain multiple simultaneous drive failures.
Ver.071015
DAS401 User’s Manual

2.3.4 PARITY RAID (RAID 5)
Parity or RAID 5 adds fault tolerance to Disk Striping by including parity information with the data. Parity RAID
dedicates the equivalent of one disk for storing parity stripes. The data and parity information is arranged on the
disk array so that parity is writte n t o diff ere nt dis k s . Ther e are at le a st 3 memb e rs t o a P arit y R AID set. The
following example illustrates how the parity is rotated from disk to disk. The following example illustrates how the
parity is rotated from disk to disk.
Parity RAID uses less capacity for protection and is the preferred method to reduce the cost per megabyte for
larger installations. Mirroring requires 100% increase in capacity to protect the data whereas the above example
using three hard drives only requires a 50% increase. The additional required capacity decreases as the number
of disks in the group increases (i.e., 33% for four drives or 25% for five drives).
In exchange for low overhead necessary to implement protection, Parity RAID degrades performance for all write
operations. The parity calculations for Parity RAID may result in write performance that is somewhat slower than
the write performance to a single disk.
2.3.5 CONCATENATION (COMBINE DRIVE)
The Concatenated mode combines multiple disks or segments of disks into a single large volume. It does not
provide any data protection or performance improvement but can be useful for utilizing leftover space on disks.
Concatenation allows the segments that make up the volume to be of different sizes.
2.3.6 SINGLE DRIVE / SEGMENT
The single drive is a virtual disk that can either be an entire disk drive or a segment of a single disk drive. Single
drive is the “Contiguous” configuration option when creating RAID Groups (or sets) in the SATARAID5 software.

2.4 RAID VOLUME STATUS
A RAID volume can be in any one of the following statuses.
STATUS
MEANING
Good All disks are currently functioning as normal.
Reduced
For RAID levels that provide data protection, one or more disks have failed but the data is
still available via the RAID algorithms. The failed disk should be replaced as soon as
possible to avoid loss of data.
Rebuilding
A failed disk drive has been replaced and the data is being regenerated on the replacement
disk. When complete, the RAID Group will return to Good status.
Resynchronizing
An error has occurred and RAID algorithms be regenerated on this RAID Group. When
complete, the RAID Group will return to Good status.
Failed
One or more disks have failed and RAID algorithms can no longer regenerate the data. The
minimum number of failures required to reach this state depends on the RAID level:
a
RAID 0, Concatenated, Contiguous: Single disk failure.
a
RAID 1, 10, and 5: Two disk failure.

The status of the newly created partition in the Disk Management window should change to Formatting and the
percentage complete will be displayed. Depending upon the size of the partition, the format process may take
several minutes. When complete, the status will change to “Healthy＂ and the name and drive letter will be
updated. Once the disk reports Healthy, it appears in the listing in System Listing section with all of its pertinent
information as well.
Repeat the above procedure as needed for any other partitions. Close the Data Management window by
