PCIe Gen 4.0 M.2 NVMe Hardware RAID controller

The ARC-1886-6N2I presents the advanced hardware RAID technology in enhanced performance of using 6 Bays M.2 NVMe and an improved enterprise data protection of using two SAS/SATA ports. The hardware RAID adapter accesses the data of NVMe disk array with a workload preset value. While the workload level stays within the preset value, the RAID adapter would constantly back up the data of NVMe disk array to the other two SAS/SATA ports hard disk arrays. This is designed in a 1.6 GHz dual-core ROC processor, DDR4-2666 memory and PCIe Gen 4.0 host/device interface and supports RAID levels 0, 1, 10, 3, 5, 6, Single Disk or JBOD.

High Bandwith 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.

• Higher bit rate - 16.0GT/s
• Higher bandwidth per lane - 2GB/s
• Higher efficiency - 98.5% encoding efficiency

The ARC-1886-6N2I RAID adapter can operate in all three modes concurrently servicing NVMe, SAS or SATA drives that offers the operation of NVMe, SAS or SATA storage devices in a single RAID adapter. With a single ARC-1886-6N2I RAID adapter, system integrators can take full advantage of 6x PCIe Gen 4.0 M.2 x2/x4 NVMe drives (or 6Gb/s M.2 SATA SSD drives) and 2x 12Gb/s SAS/SATA ports.
