This manual includes a full table of contents, index, chapter task lists and
numerous cross-references to help you find the specific information you are
looking for.
Also included are four levels of notices:
Note
A Note provides helpful information such as hints or alternative
ways of doing a task.
Important
An Important calls attention to an essential step or point required
to complete a task. Important items include things often missed.
Caution
A Caution informs you of possible equipment damage or loss of
data and how to avoid them.
Warning
A Warning notifies you of probable equipment damage or loss of
data, or the possibility of physical injury, and how to avoid them.

VTrak Overview
VTrak provides data storage solutions for applications where high performance
and data protection are required. The failure of any single drive will not affect data
integrity or accessibility of the data in a RAID protected logical drive.
Figure 1. VTrak E310f and E310s front view
A defective drive may be replaced without interruption of data availability to the
host computer. If so configured, a hot spare drive will automatically replace a
failed drive, securing the fault-tolerant integrity of the logical drive. The self-
contained hardware-based RAID logical drive provides maximum performance in
a compact external chassis.

Architectural Description
The VTrak E310f is a Fibre Channel subsystem suitable for Direct Attached
Storage (DAS), Storage Area Network (SAN), and Expanded Storage.
The VTrak E310s is a Serial Attached SCSI (SAS) subsystem suitable for Direct
Attached Storage (DAS), Cascaded Storage, and Expanded Storage.
The E310f and E310s subsystems support:
• 1.5 Gb/s SATA disk drives
• 3.0 Gb/s SATA disk drives
• 3.0 Gb/s SAS disk drives
All E310f and E310s enclosures include a mid-plane, RAID controller, power and
cooling units, and enclosure processor all in one cable-less chassis design.
Multiple fans and power supplies provide redundancy to ensure continued usage
during component failure. The RAID controller is hardware based and controls all
logical drive functions transparently to the host system. VTrak appears to the
computer’s operating system as a standard SCSI drive or drives.
Features and Benefits
Highlights
• Dual channel active/active, failover/failback RAID controllers
• 12 hot-swappable drive bays in a robust 2U rackmount chassis with
redundant, hot-swappable power and cooling modules
