Areca ARC-1886-4N8I M.2 NVMe SAS/SATA RAID PCIe 4.0
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.
Power Loss Protection (OMP)
Enterprise storage must ensure data integrity in the event of power loss and system failure. Power Loss Protection (PLP) is a hardware and firmware solution in the ARC-1886-xNxI RAID Adapter that ensures the integrity of NVMe SSDs is maintained in the event of a power loss.
