Areca ARC-1883x 8Ext SAS/SATA RAID PCIe 3.0
The new third-generation Areca ARC-1883 family of controllers offers advanced technology for enhanced performance and enhanced data protection in enterprises. They are designed with a 1.2 GHz dual-core ROC processor, DDR3-1866 memory architecture and PCIe 3.0 connectivity for the most performance-demanding data center and IT applications. The ARC-1883 family offers 8 external ports, as well as full-height 12/16/24 internal ports with an additional 4 external ports with mini SAS HD connectors providing 12 Gb/s throughput on each port.
ARECA ARC-1886-xNxI controllers present advanced hardware RAID technology with increased performance thanks to the use of 6 or 4 M.2 NVMe bays and improved protection of corporate data thanks to the use of two SAS/SATA ports.
The hardware RAID adapter accesses the data of the NVMe disk array with a given load value. While the load level remains within the set value, the RAID adapter continuously backs up the NVMe disk array data to the remaining two SAS/SATA hard disk arrays. The devices are equipped with a 1.6 GHz dual-core ROC processor, DDR4-2666 memory and PCIe Gen 4.0 host/device interface and support RAID levels 0, 1, 10, 3, 5, 6, single disk or JBOD.
