Frequently Asked Questions
What is a PCIe Gen 4.0 RAID adapter used for?
A PCIe Gen 4.0 RAID adapter like the ARC-1886-8I consolidates multiple storage drives into a single high-performance array within a server. It offloads RAID processing from the CPU, enabling faster data access, improved reliability, and simplified storage management for enterprise applications.
Can the Areca ARC-1886-8I support both SSD and HDD drives?
Yes. The tri-mode RAID controller natively supports SAS HDDs, SATA SSDs, and PCIe NVMe drives simultaneously. This flexibility allows you to mix storage types within the same array, optimizing cost and performance for hybrid workloads.
How much cache does the ARC-1886-8I provide?
The adapter includes 8GB of DDR4-2666 ECC cache, which accelerates read/write operations and improves overall system performance. The ECC (Error-Correcting Code) memory ensures data integrity during high-throughput operations.
Is the ARC-1886-8I suitable for database servers?
Absolutely. The dedicated 1.6 GHz dual-core ARM A15 RAID processor and 8GB cache make this adapter ideal for database servers requiring low-latency, high-throughput storage. It reduces CPU overhead and delivers consistent performance for transactional workloads.
