drives. Regardless of the drive speed, 12Gb/s SAS RAID controllers
will provide maximum read/write performance improvements for
the most performance-hungry database and IT applications.
The ARC-1883ix includes one 12Gb/s SAS expander that incorpo -
rates 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 allow-
ing users to take advantage of 12Gb/s speeds while utilizing exist -
ing 6Gb/s drives and backplanes. Using DataBolt, the ARC-1883ix
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
Unsurpassed Data Availability
Designed and leveraged with Areca’s existing high performance
RAID solution, ARC-1883 provides superior levels performance
and enterprise level data protection for the most demanding next-
generation server and storage environments. It supports the hard-
ware RAID 6 engine to allow two HDDs failures without impact the
existing data and performance. It allows users to hot swap drive in
the event of a drive failure with zero downtime. The optional flash-
based backup module provides power to transfer the cache data
from the SDRAM memory to the NAND flash memory if it contains
data not yet written to the drives when power is lost. ARC-1883
also supports traditional Lithium-ion (Li-ion) battery backup mod-
ule (BBM) to protect cached data on RAID adapters. Board-level
hardware encryption manages any kinds of drives attached to ARC-
1883 controller cards for higher levels of security. API code sup -
ports for third-party Enterprise Key Management systems to easy
integrate and manage encryption function.
Maximum Interoperability
The 12Gb/s SAS RAID controller support broad operating system
including Windows, Linux (Open Source), FreeBSD (Open Source),
Solaris (Open Source), Mac, VMware and more, along with key
system monitoring features such as enclosure management (SES-
2, SMP, & SGPIO) and SNMP function. Our products and technology
are based on extensive testing and validation process; leverage
