1. Introduction
This section presents a brief overview of the 6Gb/s SAS RAID storage,
ARC-8050. (Thunderbolt to 6Gb/s SAS RAID storage)
1.1 Overview
Thunderbolt technology is a revolutionary high-speed, dual proto-
col I/O technology designed for performance, simplicity and ex-
ibility. Thunderbolt I/O technology lets you move data between
high-resolution displays and high-performance data devices on a
single, compact port. Both data and display signals can be sent
and received at the same time through dual 10Gbps channels. A
single cable attached to one of the ports provides 2 channels able
to achieve the 10Gbps speeds owing both ways simultaneously. A
single Thunderbolt port supports hubs as well as a daisy chain of
up to seven Thunderbolt devices. To improve bandwidth transmis-
sion, Thunderbolt has implemented two duplex (PCIe and Display-
Port) channels into the controller and each channel can provide full
bi-directional performance.
Unparalleled Performance
ARC-8050 is 8-bay 6Gb/s SAS Thunderbolt box with RAID control
capabilities solution for both PC and Mac. Thunderbolt host inter-
face make ARC-8050 RAID box well suited for SOHO group profes-
sional who work at home and or in the ofce. Thunderbolt technol-
ogy developed for high speed data transfer at the speed of 10Gbps
per channel. Thunderbolt port is shared by multiple devices and
can transfer data equally distribute to all connected devices. ARC-
8050 incorporated on-board high performance dual core 800Mhz
ROC storage processor and with 1GB DDR3-1333 SDRAM memory
on-board to deliver true high performance hardware RAID for the
demands of serious HD media creators needs. For example, the
benet for video editor by using ARC-8050 to unleash their profes-
sional creativity work in real-time, with the high-bandwidth allow
large amount of audio and video capture/mixing devices trans-
ferred faster with low latency and high-accurate synchronization
at 10Gbps. Data can be backed up and restored more quickly, so
there’s less waiting for achieved content to transfer or copy.

Unsurpassed Data Availability
Designed and leveraged with Areca’s existing high performance
solution, the RAID storage delivers high-capacity at the best of cost
performance value. It supports the hardware RAID 6 engine to al-
low two HDDs failures without impact the existing data and perfor-
mance. Its high data availability and protection derives from the
many advance RAID features. ARC-8050 Thunderbolt RAID storage
allows easy scalability from JBOD to RAID. It can be congured to
RAID levels 0, 1, 1E, 3, 5, 6, 10, 30, 50, 60, Single Disk for JBOD.
With innovative new ROC 6Gb/s SAS feature and support for SATA,
SAS and SSDs, the ARC-8050 provides powerful small-workgroup
server, power users and consumers with superior levels perfor-
mance and enterprise level data protection for external storage.
The world today, large amounts of arrays data needs by the Profes-
sional content creation application for – video editing, capturing or
transferring video, managing 3D graphics design, producing video
presentations and regularly data backup. ARC-8050 Thunderbolt
RAID storage is the best solution.
Easy RAID Management
Conguration and monitoring can be managed either through the
LCD control panel, Archttp utility or Ethernet port. Firmware-em-
bedded web browser-based RAID manager allows local or remote
to access it from any standard internet browser via a out-of-band
10/100Mbits LAN port or in-band Archttp utility. ARC-8050 Thun-
derbolt RAID storage also provides API library for customer to
combine with its own monitor utility. The intelligent cooling con-
tinuously adapts to environmental conditions by automatically
controlling the speed of the cooling fans. This super silent design,
optimizing balance between noise reduction and necessary cooling,
makes ARC-8050 well suited for audio/video application especially
the rapidly growing demand from the video editing markets.
