Areca ARC-8026-12 プリント
Easy Management
Overview
SAS for Maximum Scalability
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 preferred I/O
connection for server and JBOD backplanes is
the internal SFF-8087 connector. This connector
has eight signal pins to support four SAS/SATA
drives and six pins for the SFF-8485 compliant
SGPIO (Serial General Purpose Input/Output)
side-band signals. 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

Maximum Interoperability
Areca presents its ultra-high performance and
high reliability 6Gb/s SAS expander module for a
cost-effective and enterprise-class JBOD storage
enclosure. A 6Gb/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-8026 SAS expander, you can build large and
complex storage topologies. When Areca SAS
6Gb/s RAID adapter used with ARC-8026
expanders, the RAID adapters can provide up to
(128) devices through one or more 6Gb/s SAS
JBODs, making it an ideal solution for
high-bandwidth applications and
transaction-intensive enterprise-class storage
applications that call for maximum configuration
flexibility. Applications that benefit most features
from these solutions include online transaction
processing, server RAID solutions,
supercomputing, near-line backup, security
systems, streaming and cloud computing
applications.

The Areca SAS Expander module
ARC-8026 is based on the LSI
LSISAS2x36/28 expander IC,
SAS-2 chip which features 36/28 x
6Gb/s ports and 6G/3G
multiplexing, SAS 2.0 zoning,
self-configuration, table-to-table
routing, and an integrated PPC
processor for SES-2 and enclosure
management support. The
ARC-8026 expander module
features three 6Gb/s SAS 4x
SFF-8088 ports; one host and two
for expansion to additional JBOD
enclosures. It is designed to fit into
a stand-alone box and can be
installed in a 5.25”mounting shell.
The Areca SAS expander box is
ideal for enclosure customers that
want to support up to 24 channels
6Gb/s and 3Gb/s SAS/SATA/SSD
JBOD function units using low-cost
SFF-8087 SAS cables. It has been
fully tested and qualified with
6Gb/s and 3Gb/s Areca external
SAS/Fibre/iSCSI/PCIe to SAS
RAID controller, SAS RAID
adapters and HBAs.
