Frequently Asked Questions
What is a PCIe Gen 4.0 M.2 NVMe hardware RAID adapter?
A PCIe Gen 4.0 M.2 NVMe hardware RAID adapter is a specialized storage controller that manages multiple NVMe drives with dedicated RAID processing. The ARC-1886-4N8I uses a dedicated ROC processor to handle RAID operations independently, offloading this work from your system CPU and delivering consistent high-speed performance.
What are the benefits of tri-mode RAID support?
Tri-mode support means the ARC-1886-4N8I can manage NVMe, SAS, and SATA drives simultaneously in the same RAID array. This flexibility allows enterprises to mix storage technologies, protect legacy investments, and optimize costs by using the right drive type for each workload.
How does the dual-core ROC processor improve performance?
The dedicated 1.6 GHz dual-core ROC processor handles all RAID calculations, parity checks, and data protection tasks independently. This offloads processing from your host system, reducing CPU overhead and enabling the adapter to deliver maximum throughput without impacting system performance.
Which RAID levels does the ARC-1886-4N8I support?
The adapter supports RAID 0 (striping), RAID 1 (mirroring), RAID 10 (striped mirrors), RAID 3 (striping with parity), RAID 5 (distributed parity), RAID 6 (dual parity), Single Disk mode, and JBOD (Just a Bunch of Disks) for maximum flexibility in data protection strategies.
