1. Introduction
This section presents a brief overview of the 6Gb/s SAS RAID storage,
ThunderBox 800. (Thunderbolt 2 to 6Gb/s SAS RAID storage)
1.1 Overview
Unleash Your Creativity Faster Than Ever
Thunderbolt 2 is full backward compatibility to the same cables
and connectors used with today’s Thunderbolt. It pushes speed to
20Gb/s and enables 4K video le transfer and display simultane-
ously. ThunderBox 800 is equipped with dual Thunderbolt 2 ports
for connecting to any Thunderbolt 2-enabled host such as the new
Mac Pro, and offers an additional Thunderbolt 2 port for daisy-
chaining other peripherals. The Thunderbolt daisy-chaining allows
connection of up to six devices, so customers can connect Thunder-
Box 800 for massive amounts of video storage with a single Thun-
derbolt connection to their host computer. ThunderBox 800 can
meet the demand of users when working with rich, ultrahigh
resolution media through Thunderbolt 2 interface.
Unparalleled Performance for 4K Workow
ThunderBox 800 is the most complete 6Gb/s SAS 8-bay Thunder-
bolt 2 box with RAID control capabilities solution for both PC and
Mac. ThunderBox 800 incorporated on-board dual core 800Mhz
RAID-On-Chip and with 1GB DDR3-1333 memory to deliver true
high performance hardware RAID protection against drive failure.
This combination helps to provide a high performance storage
device perfect for the video editor working with Real time multi-
stream HD and 4K workows. It runs efciently without disruption
or major drops in performance to meet the requirements of 4K
data workow. It is so quick it allows for 4K displays at the same
time as daisy chaining ThunderBox 800 and doing a simultaneous
4K output and le transfers while maintaining maximum through-
put.

INTRODUCTION

Enterprise-class Data Availability and Security
ThunderBox 800 supports the hardware RAID 6 engine to allow two
HDDs failures without impact the existing data and performance.
It allows users to hot swap drive in the event of a drive failure with
zero downtime. Its high data availability and protection derives
from many advanced RAID features on ThunderBox 800 RAID box
design. Intelligent power On/Off function on storage turns power
in unison with the host computer power status. It can intelligently
power down the unit after the thunderbolt host shuts down every-
thing for data integrity. ThunderBox 800 also supports a battery
backup option that protects all data in cache memory in the event
of unexpected power outage. Board-level hardware encryption
manages any kinds of drives attached to ThunderBox 800 without
impacting the performance for higher levels of security.
Enabling an Easy-to-Manage Storage
Conguration and monitoring can be managed either through the
LCD control panel, Thunderbolt interface or LAN port. The intel-
ligent cooling continuously adapts to environmental conditions by
automatically controlling the speed of the cooling fans for the rap-
idly growing demand from the video editing markets. You can even
congure ThunderBox 800 to intelligently spin down drives during
periods of inactivity to further reduce noise and save energy. Areca
solution of Thunderbolt 2 provides user the capability of adding
bootable drive via Thunderbolt on Apple thunderbolt-capable ma-
chine.

2.5 Setting Up RAID Storage
Setting up your ThunderBox 800 involves these main steps:
• Physically Install the RAID Storage and Drives
• Install the MRAID Software
• Congure RAID Volumes
• Format RAID Volumes
• Unmounting RAID Volumes
Details about these steps are described in the following sections.
2.5.1 Physically Install RAID Storage and Drives
Please follow the steps below in order they are given to ensure
that your ThunderBox 800 connected on your Thunderbolt com-
puter.
Step 1. Install the Drives in the ThunderBox 800
Your RAID storage supports up to 8 x 3.5-inch disk drives or 8 x
2.5-inch SAS or SATA 6.0Gb/s drives, each one contained in its
individual hole on the disk carrier. Each drive is hot-pluggable,
allowing you to remove and insert drives without shutting down
your RAID storage. Installation in this section describes how to
install or remove 3.5 inch drives in your RAID storage.
1. Gently slide the drive tray out from the ThunderBox 800 RAID
storage.
Thunderbolt Ports
Link LED Status
Green light 1. Lit indicates RAID storage is powered and maintained
the daisy chain with other Thunderbolt devices.
2. Blinking (5 times/sec) that indicates RAID storage is
in sleep mode.
3. Blinking (1 time/sec) that indicates RAID storage is
powered down and maintained the daisy chain with
other Thunderbolt devices.
Amber light There is a proper DisplayPort connection on that Thun-
derbolt port.
Red light There is a proper DisplayPort to DVI connection on that
Thunderbolt port.

INSTALLATION

2. Install the drive into the drive tray and secure the drive to the
drive tray by four of the mounting screws.
Figure 2-5, Sliding Drive Tray into Enclosure
3. After all drives are in the drive tray, slide all of them back into
the ThunderBox 800 and make sure you latch the drive
trays.
