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-dene manufacture default set-
ting on those connections. Conguration 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
conguration 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 congurations
of SAS end devices, including SAS host/RAID adapters and SAS
and SATA disk drives. The SAS protocol denes 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 benets
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 conguration 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.
