Product Components
The K-Series RAID system consists of a RAID controller (SCSI-to-IDE); six IDE drive bays and
drive tray assemblies; redundant, hot-swappable power supplies; redundant, hot-swappable fans;
and an enclosure to house and integrate these components.
RAID Controller
The SCSI-to-IDE controller used in the K-Series RAID system is the central element of the
product. A hardware RAID controller is a Òpurpose builtÓ, and sophisticated, computer that
manages data flow to and from the array of disk drives in the most fault-tolerant manner possible.
The RAID controller used in the K-Series RAID system supports RAID levels 0, 1(0+1), 3, and 5;
and provides the user interfaces for system management, monitoring, and event notification.
IDE Drive Bays and Drive Tray Assemblies
Drive bays are the spaces provided in the K-Series enclosure for disk drives. The drive tray
assemblies are containers that house the individual drives and permit hot-swapping. The bays and
drive assemblies in the product are designed for contemporary 3.5Ó x 1Ó EIDE disk drives.
Power Supplies
The system comes with two (2) redundant, hot-swappable power supplies. Each power supply
provides power to the RAID system simultaneously and each is capable of supplying the required
power to the RAID system - alone if necessary. Note that prolonged single power supply operation
is not recommended (and compromises the high availability intent of the system). Operating the
system with only one power supply should only take place if a power supply failure occurs. Failed
power supplies should be replaced as soon as possible.
Fans
The system comes standard with two (2) redundant, hot-swappable drive cooling fan modules.
Each fan module contains two (2) fans and provides airflow to the three (3) drive bays to their left.
Note that prolonged single fan operation is not recommended (and compromises the high
availability intent of the system). Operating the system with a failed fan should only occur if a fan
fails. Failed fan modules should be replaced as soon as possible.
Enclosure
The ÒenclosureÓ (or system cabinet) houses the controller, drives/drive tray assemblies and bays,
power supplies, and fans. The enclosure effectively combines (or integrates) all of the individual
components to form the complete RAID system. The enclosureÕs controls and features are
described throughout this manual.
