Frequently Asked Questions
What is a PCIe Gen 4.0 RAID adapter and why do I need one?
A PCIe Gen 4.0 RAID adapter is a hardware controller that manages multiple storage drives while providing RAID protection and data redundancy. The ARC-1886-8i's Gen 4.0 interface delivers twice the bandwidth of Gen 3, making it ideal for high-speed NVMe arrays, large SAS/SATA configurations, and virtualized environments where I/O performance is critical.
Can the Areca ARC-1886-8i support both NVMe and traditional SAS/SATA drives?
Yes. The tri-mode design of the ARC-1886-8i enables simultaneous support for PCIe NVMe SSDs, 12Gb/s SAS drives, and SATA drives. This flexibility allows you to mix storage types within a single RAID array or manage separate arrays for different workload requirements.
How many drives can this RAID controller manage?
The ARC-1886-8i supports up to 512 drives through SAS expanders, making it suitable for large-scale storage deployments, data warehouses, and enterprise backup systems. The ARM A15 RAID-on-Chip architecture ensures efficient management without burdening your server CPU.
Is the Areca ARC-1886-8i compatible with VMware ESXi and other hypervisors?
Absolutely. The ARC-1886-8i is certified for VMware ESXi, XenServer, and other major hypervisor platforms, plus Windows, Linux, FreeBSD, and macOS. This broad compatibility makes it an excellent choice for virtualized data centers and mixed-OS environments.
