Areca ARC-8028-32 Leaflet
Easy Management
Overview
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 configurations of SAS end devices,
including SAS host/RAID adapters and SAS and
SATA disk drives. The SAS protocol defines a
mechanism that has been implemented in the
SAS expanders to guarantee fair access
between drives in a domain. With ARC-8028
SAS expander, you can build large and complex
storage topologies.

The expander box contains an embedded
expander manager that can access via in-band
SES-2 over SMP protocol and out-of band
RS-232 port. An out-of-band serial port is
available for managing the configuration and
monitoring the expander. The Areca expander
firmware and EPLD has implemented the SES-2
protocol and disk activity map to SGPIO based
indicator LEDs. For backplane without SGPIO
supporting, the expander box also provides two
kinds of alternative LED cable header to support
the individual fault/activity status indicator for
those backplanes. In addition to meet different
enclosure, ARC-8028 expander box has
implemented autonomous chassis management
of two power supplies status connectors, four fan
monitor/speed control connectors through the
SES-2 protocol. Firmware and configuration data
including vendor identification strings can be
customized or tuned for each customer.

ARC-8028 SAS Expander Module
The 12Gb/s SAS ARC-8028 expander module is
designed with an integrated ARM Cortex-R4
processor for topology management functions
such as discovery, enclosure and drive
management, and LED management. The
ARC-8028 expander module features three or
four 12Gb/s SAS SFF-8644 ports. It is designed
to fit into a stand-alone box and can be installed
in a 5.25”mounting shell. The ARC-8028 is ideal
for enclosure customers that want to support up
to 24/32 channels 12Gb/s SAS or 6Gb/s and
3Gb/s SAS/SATA JBOD function units using
SFF-8643 SAS cables. The ARC-8028 firmware
has been included the failover to utilize the most
up-to-date technology available, providing your
system with reliable, high-quality performance.
User can configure ARC-8028 redundant mode
with multiple expander module using either RAID
controllers or HBAs to achieve failover protection.

ARC-8028 supports DataBolt™ Bandwidth Optimizer to
buffer 6Gb/s data and then transfer it out to the host at
12Gb/s speeds in order to match the bandwidth between
faster hosts and slower SAS or SATA devices. It also
supports failover function for improving system reliability for
today’s data center and storage subsystems.
Unparalleled Performance
The ARC-8028 series expanders include 24/32
internal plus 12/16 external 12Gb/s SAS ports
connection for host and easy expansion. High
performance architecture sets new boundaries
of industry performance expectations: 12Gb/s
SAS or 6.0Gb/s and 3Gb/s SAS/SATA. The
ARC-8028 incorporates the latest enhancements
in SAS along with new LSI DataBolt bandwidth
optimizer technology. This is designed to help
facilitate the industry 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-8028 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.
