1. Introduction
This section presents a brief overview of the ARC-4038 compact tower
12Gb/s SAS JBOD enclosure.
1.1 Overview
The ARC-4038 SAS-to-SAS JBOD box provides a compact external
storage chassis capable of accommodating up to 8/12 12Gb/s Se-
rial-Attached SCSI (SAS) drives or 6Gb/s Serial ATA (SATA) drives.
The box can support both 3.5-inch disk drives and 2.5-inch disk
drives, each one contained in its individual hole on the disk carrier.
The expander module on ARC-4038 is designed with an integrated
ARM Cortex-R4 processor for topology management functions such
as discovery, enclosure and drive management, and LED manage-
ment. Each ARC-4038 compact tower JBOD supports four 12Gb/s
SFF-8644 and one 6Gb/s SFF-8088 SAS host and expansion con-
nections. Out-of-band CLI can re-dene manufacture default set-
ting on those connections. Conguration and environmental in-
formation is accessible either via in-band (SES-3.0 over SMP) or
out-of-band serial port.
Unparalleled Performance
The 12Gb/s ARC-4038 offers 28 ports of connectivity in a 8/12-bay
desktop tower. It can provide internally connectivity for up to 8/12
direct attached SAS/SATA HDDs and or SSDs and 20 external ports
(using 4 x SFF-8644 and 1 x SFF-8088 connector) for storage host/
expansion connections. High performance architecture sets new
boundaries of industry performance expectations: 12Gb/s SAS or
6.0Gb/s and 3Gb/s SAS/SATA. The ARC-4038 incorporates the lat-
est enhancements in SAS along with new LSI DataBolt bandwidth
optimizer technology. This is designed to help facilitate the indus-
try transition to 12Gb/s SAS-enabled systems by allowing users
to take advantage of 12Gb/s speeds while utilizing existing 6Gb/s
drives and backplanes. Using DataBolt, the ARC-4038 buffers
6Gb/s data and then transfers it out to the host at 12Gb/s speeds
in order to match the bandwidth between faster hosts and slower
SAS or SATA devices.

Easy Management
The ARC-4038 contains an embedded expander manager that can
access via in-band SES-3.0 over SMP protocol and out-of band RS-
232 port. An out-of-band serial port is available for managing the
conguration and monitoring the expander. The ARC-4038 expand-
er rmware and EPLD has implemented the SES-3.0 protocol and
disk activity map to the individual fault/activity status indicator on
the backplanes. It has implemented autonomous chassis manage-
ment of power supply status connectors, two fan monitor/speed
control connectors through the SES-3.0 protocol. In data center
environments, identifying issues with drives and environments are
crucial. The hardware monitor can monitor system voltage and em-
perature. The warning message will be shown in alarm buzzer and
respect LED.
Maximum Interoperability
Areca presents its ultra-high performance and high reliability
12Gb/s SAS expander module for a cost-effective and enterprise-
class JBOD storage enclosure. A 12Gb/s SAS expander module
literally expands the number of end devices that you can connect
together. Expander devices, typically embedded into an expander
module to connect system backplane, support large congurations
of SAS end devices, including SAS host/RAID adapters and SAS
and SATA disk drives. The SAS protocol denes a mechanism that
has been implemented in the SAS expanders to guarantee fair ac-
cess between drives in a domain. The ARC-4038 is ideal for 12Gb/s
SAS storage systems with external interfaces and get the benets
of more storage capacity. The type and total amount of drives you
use are based on the host interface in the server that the JBOD is
connected. Host-based RAID conguration is supported via an ex-
ternal connectors on PCIe to 12Gb/s SAS RAID controller, external
series SAS/Fibre/iSCSI to 12Gb/s SAS RAID and SAS host adapt-
ers.
