Enterprise RAID Controller

The Areca ARC-1886-8I is a PCIe 4.0 TriMode RAID adapter that connects up to eight SAS, SATA or NVMe devices through a single x8 host interface. An on-board 1.6 GHz dual-core ROC processor and 8GB DDR4-2666 cache accelerate parity calculations for database and virtualization workloads.

Suited For High-Density Arrays

This card suits administrators building dense NVMe arrays, supporting up to 24 drives when paired with a PCIe switch. It is not for workstations limited to consumer chipsets, systems lacking an x8 electrical slot, or deployments that require hardware RAID 5EE or 6EE levels.

Sustained Write Throughput

The DDR4-2666 cache absorbs burst writes and maintains consistent parity performance during extended rebuilds or heavy OLTP streams. Active cooling in a server chassis keeps the ROC processor at stable clocks so throughput does not throttle under continuous 12Gb/s device traffic.

Questions about this item

What host interface slot does the ARC-1886-8I require?

The controller needs a PCIe 4.0 x8 slot on the motherboard to operate at its rated speed.

Can the tri-mode ports connect to my existing 6 Gb/s SATA drives?

Yes, the 12 Gb/s SAS/SATA/PCIe ports are backward compatible with 6 Gb/s SATA devices.

How do I verify the 8 GB DDR4-2666 cache is active after installation?

Check the RAID management utility; it will display the cache size and DDR4-2666 speed when the controller posts.
