PCIe Gen 4.0 M.2 NVMe Hardware RAID controller






The ARC-1886-xNxI 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.

Ultrafast Transfer Speed




Unprecedented Performance



ARC-1886-xNxI PCIe Gen 4.0 M.2 NVMe Hardware RAID adapter is built to deliver unprecedented performance, using only carefully, best-in-class components. These include the dual core Broadcom SAS3916, PCIe Gen 4.0 tri-mode ROC, 8GB DDR4-2666 SDRAM with ECC protection.






Powerful Broadcom Tri-mode ROC Engine



At the heart of ARC-1886-xNxI is the incredibly powerful Broadcom 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-1886-xNxI hardware RAID relieves the parity generation burden from the host and maximizes application processing performance.








Speed Up 8GB DDR4-2666 SDRAM



With a massive 8GB of DDR4-2666 SDRAM, ARC-1886-xNxI gives you super-smooth multitasking during the period of high overload in 4K environment. ARC-1886-xNxI firmware can configure how much cache SDRAM dedicated for read, and how much for write. If your server application has significantly more reads than writes or more writes than reads, you might need to change this setting to adjust the read/write cache ratio for improving performance. Big cache is the perfect choice for a 4K application drive, making your professional apps work as fast as possible.

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.



Higher bit rate - 16.0GT/s


Higher bandwidth per lane - 2GB/s


Higher efficiency - 98.5% encoding efficiency











Professional Storage Connectivity




The ARC-1886-xNxI 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-xNxI 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.





Auto-Backup Between Dual Array



---  need to be verified, until Q4 2022  ---



NVMe disasters always happen unexpectedly, and without proper safeguards your data could be in jeopardy. Implementing an Auto-backup and Recovery strategy is critical for protecting a NVMe array from the corruption of data and for providing the ability to recover that data.The ARC-1886-xNxI provides a dual disk arrays including a NVMe disk array and a hard disk array. The RAID firmware has a preset value, and when the workload size does not reach the preset value, it backs up the data of M2 NVMe disk array to the SATA connector port hard disk array. This has the advantages of fast access to data by the NVMe disk and high reliability of data storage on the hard disk. These backups contain exact copies of NVMe array. The clone SAS/SATA array uses them for disaster recovery purposes.





Off Module Power (OMP) Loss Protection



An enterprise storages need to ensure data integrity in the event of power losses and system crashes. The Power Loss Protection (PLP) is a hardware and firmware solution on the ARC-1886-xNxI RAID adapter to ensure that the NVMe SSDs integrity is maintained should a power loss event occur.





Launch the web browser-based  MRAID storage manager  to check the  power loss event .

Smart CBM for the Integrity of the Cached Data



ARC-1886-xNxI RAID storages have integrated caches for increasing performance. With corresponding protective mechanisms, the content of these unwritten cached data in the SDRAM would be lost when there is a complete AC power failure or a brief unexpected power outage. For that reason, a cache backup module (CBM) protects the integrity of the cached data on ARC-1886-xNxI RAID adapter by providing backup power. The cache backup module has built-in functionality to charge the supercapacitor pack automatically and to communicate supercapacitor pack status information to the RAID adapter.









Controller-Based H/W Encryption Engine




Host independent real-time controller-based hardware encryption does not impact the performance of ARC-1886-xNxI RAID adapter and can implement on
