Entry Level M.2 NVMe Hardware RAID Adapters




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.

Ultrafast Transfer Speed




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.



Higher bit rate - 16.0GT/s


Higher bandwidth per lane - 2GB/s


Higher efficiency - 98.5% encoding efficiency











Professional Storage Connectivity




The ARC-1686-xNOD 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-1686-xNOD 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





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-1686-xNOD 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 .

Fault LED Stay on for Troubleshooting




On-board Supercapacitor keeps M.2 fault LED status to easy identify failed drive when ARC-1686 RAID adapter removes from the system PCIe slot.









Power Disable Feature (PWRDIS)




The ARC-1686 Power Disable feature provides a M.2 management capability to electrically power cycle a physical NVMe drive in order to perform a power on reset. This can be useful if a NVMe drive locks up for some reason, and you don’t want to send a technician to the physical RAID storage and manually "power down" and "power on" your system in order to power cycle the NVMe drive. Now, ARC-1686 can do this function automatically to check the drive is indeed failed or can be re-used. ARC-1686 Power Disable feature is similar as Power Disable Feature (PD) - disk cold boot management feature introduced with SATA 3.3 - February 2, 2016.









SED-Based Encryption




The ARC-1686-xNOD RAID adapter firmware Security Function, together with self-encrypting drives (SEDs), secures a data in the hard disks from unauthorized access or modification resulting from theft, loss or repurposing of drives. Protection is achieved by the SED hard drive that automatically and continu¬ously encrypts the data on the drive without any user interaction.









Multi-booting Capability




There are many advantages features for ARC-1686-xNOD RAID adapter uEFI support for more than one macOS version to reside on one Apple machine.

(1). Support a primary operating system and an alternate system that you use less frequently

(2). Allows a new operating system to configure all applications needed, and migrate data before removing the old operating system

(3). Useful in situations where different software applications need different operating systems

(4). Software developers needs to have multiple operating systems for development or testing purposes

The user would need to simply reboot the device and select the alternate option to switch from one version to others version.









Effective Management Tool




Areca provides more flexible management tools to manage and monitor ARC-1686-xNOD RAID adapter.



• PCIe Bus




Lets you set up and manage RAID storage through In-band web browser manager and ArcSAP utility

You can configure in-band management for communication to travel over the PCIe bus path between a data host and ARC-1686-xNOD RAID adapter. In-band management uses a proxy agent HTTP management software (ArcHTTP) running on a data host to communicate with an ARC-1686-xNOD RAID adapter.







Web Browser-Based Management




McRAID storage manager is firmware-based utility, which is accessible via the web browser installed on your operating system. The web browser-based McRAID storage manager is a HTML-based application, which utilizes the browser (Safari, IE and Mozilla etc) install
