Frequently Asked Questions
What is a tri-mode RAID adapter and why do I need one?
A tri-mode RAID adapter supports three different storage interface types—NVMe, SAS, and SATA—on a single controller card. This flexibility allows you to mix and match storage technologies in your infrastructure, optimize costs by using the right drive type for each workload, and future-proof your investment as storage technologies evolve.
How does PCIe Gen 4.0 improve performance compared to earlier generations?
PCIe Gen 4.0 doubles the bandwidth of PCIe 3.0, delivering up to 16 GT/s per lane. For the ARC-1886-16i, this means faster data transfers between your host system and storage drives, reduced latency, and the ability to fully utilize high-speed NVMe SSDs without bottlenecks—critical for demanding applications like virtualization, databases, and real-time analytics.
Can the ARC-1886-16i support mixed SSD and HDD configurations?
Yes. The 16-port RAID controller excels in mixed-drive environments. You can configure NVMe SSDs for high-performance tier workloads, SAS drives for mid-tier applications, and SATA drives for archival or capacity-focused storage—all managed by a single intelligent controller with advanced RAID levels for optimal data protection.
What RAID levels does the ARC-1886-16i support?
The adapter supports RAID 0, 1, 3, 5, 6, 10, 50, and 60. This comprehensive range allows you to balance performance, capacity, and redundancy based on your specific workload requirements—from high-speed RAID 0 for non-critical data to fault-tolerant RAID 6 for mission-critical applications.
