Areca ARC-1686-2NOD 2xNVMe M.2 RAID
The ARC-1686 series presents the advanced hardware RAID technology in enhanced performance of using 2/4/6 Bays M.2 NVMe. The hardware RAID adapter support off module power loss protection (PLP), on-board hold up supercapacitor, and M.2 slot Power Disable feature for guaranteed data protection. This is designed in a 1.6 GHz dual-core ROC processor and PCIe Gen 4.0 host/device interface and supports RAID levels 0, 1 (Simple/Multi Mirroring), 10, Single Disk (Single/Dual/Triple) or JBOD.
Unprecedented Performance
Based on the Broadcom SAS3908/SAS3916 x8 PCIe Gen 4.0 to SAS/SATA/PCIe RAID on Chip (ROC) controller, the ARC-1686 entry-level RAID adapter raises the standard to higher performance levels with several enhancements including a new high performance 1.6 GHz dual core ROC processor, outstanding performance PCIe Gen 4.0 host and 12Gb/s SAS/SATA/PCIe (NVMe) interface bus interconnection.
Powerful Broadcom Tri-mode ROC Engine
At the heart of ARC-1686-xNOD is the incredibly powerful Broadcom SAS3908/SAS3916 dual-core ARM A15 tri-mode ROC, giving effortless performance as desirable. It delivers storage interface PCIe Gen 4 NVMe, 12Gb/s SAS, 6Gb/s SATA, and the security of data protection. Damage in a software RAID is considered as the consumption of massive computation and memory bandwidth on the host. The ARC-1686-xNOD hardware RAID relieves the parity generation burden from the host and maximizes application processing performance.
High Bandwidth PCI-E 4.0 Support
To run the PCIe Gen 4.0 slots in Gen 4 speed, please must install the ROC which supports PCI Express 4.0. If you install the PCIe3.0 ROC, the PCI Express 4.0 slots will run only at Gen3 speed.
