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
configuration and monitoring the expander. The ARC-4038 expand
-
er firmware 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 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 ac-
cess between drives in a domain. The ARC-4038 is ideal for 12Gb/s
SAS storage systems with external interfaces and get the benefits
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 configuration 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.
