ARC-1886-xNxI Features:

  • Controller-level hardware encryption and SED support for encryption capable drives
  • Support up to 256 SATA or SAS devices using SAS expanders
  • Firmware automatically backup from NVMe RAID to SAS/SATA RAID
  • Device interface PCIe Gen4 NVMe / 6Gb/s SATA per M.2 slot
  • PCIe 4.0 host interface, PCIe Gen4 x8 lanes at maximum transfer rate up to 128Gb/s
  • Supports up to 4/6 x PCIe Gen 4.0 M.2 slots and 1x SFF-8654[x8] / 2 x SATA connector
  • CBM module or on-board battery(CR2032) to keep on M.2 fault LED status for troubleshooting
  • Hardware-based RAID solution that supports RAID levels 0, 1, 10, 3, 5, 6, Single Disk and JBOD
  • Implemented 8GB 72-bit DDR4-2666 SDRAM providing hardware RAID assist engine for parity calculations
  • Dynamically allocate storage 12Gb/s SAS/SATA/PCIe (NVMe) to NVMe slot1 and SATA/SAS ports on ARC-1886-6N2I
  • Support off module power loss protection (PLP) saves data issued without data loss at power fail using optional CBM module
The ARC-1886-6N presents the advanced hardware RAID technology in enhanced performance of using 6 Bays M.2 NVMedrives. 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.
Multi-booting Capability:

There are many advantages features for ARC-1886-xNxI 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.
