Introduction
The SurfRAID TRITON Mini is an Ultra 320 LVD SCSI-to-Serial ATA II RAID
(Redundant Arrays of Independent Disks) disk array. It consists of a RAID
disk array controller and four (4) disk trays.
The SurfRAID TRITON Mini is “Host Independent” supporting RAID levels 0,
1, 3, 5, 0+1 and JBOD. Regardless of the RAID level that the SurfRAID TRI-
TON Mini is configured for, each RAID array consists of a set of disks which
to the user appears to be a single large disk capacity.
One unique feature of these RAID levels is that data is spread across sepa-
rate disks as a result of the redundant manner in which data is stored in a
RAID array. If a disk in the RAID array fails, the SurfRAID TRITON Mini con-
tinues to function without any risk of data loss. This is because redundant
information is stored separately from the data. The redundant information can
be used to reconstruct any data that was stored on a failed disk. In other
words, the SurfRAID TRITON Mini can tolerate the failure of a drive without
losing data while operating independently of each other.
The SurfRAID TRITON Mini is also equipped with an environment controller
which is capable of accurately monitoring the internal environment, such as
its power supplies, fans, temperatures and voltages. Its modular design al-
lows hot-swapping of hard drives without interrupting the SurfRAID TRITON
Mini’s operation.

1.2 RAID 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 array.
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 deter-
mines 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 array, 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.
