Areca ARC-1886-16I 8-Lane PCI Express 4.0 8GB Tri-Mode RAID Adapters
The Areca ARC-1886-16I is a Tri-Mode RAID adapter designed to provide high-speed storage connectivity for enterprise servers and storage systems. It uses an 8-lane PCI Express 4.0 host interface and supports SAS, SATA, and NVMe storage devices from a single controller platform.
The adapter features a Tri-mode Dual Core ARM A15 1.6GHz RAID-on-Chip controller and 8GB of onboard DDR4-2666 SDRAM with ECC protection. This combination provides dedicated processing and cache resources for storage workloads and RAID operations.
With 16 internal ports and two SFF-8654 x8 connectors, the ARC-1886-16I provides flexible internal drive connectivity. It supports data transfer rates of up to 12Gb/s SAS/SATA/Gen 4.0 PCIe (NVMe) per port, allowing it to connect high-speed storage devices within compatible server configurations.
The controller supports up to 512 SAS or SAS/SATA HDDs and SSDs when using a 12Gb/s SAS expander. It can also support up to 32 NVMe drives through PCIe switches, making it suitable for high-density storage environments requiring a mixture of storage technologies.
The Areca ARC-1886-16I is suited for enterprise servers, RAID storage systems, data-intensive applications, and storage infrastructures that require flexible SAS, SATA, and NVMe connectivity. Its compact adapter design, approximately 14-watt power consumption, and 0°C to 60°C operating temperature support integration into server and storage platforms.
