Description
Areca ARC-1886-4N8I
The new fourth generation ARC-1886 family offers advanced technology for increased performance and improved enterprise data protection. They were designed with 1.6 GHz dual core ROC processor, DDR4-2666 memory and PCIe 4.0 interface for the most performance-hungry database and IT applications. Based on the ARM A15 PCIe 4.0 x8 to SAS/SATA/PCIe RAID on Chip (ROC) controller, the ARC-1886 series RAID adapters can offer both PCIe Gen 4.0 host and 12Gb/s SAS/SATA/PCIe (NVMe) tri-mode storage interfaces.
ARC-1886 Features:
- Support up to 8GB DDR4-2666 cache
- SFF-9402 compliant connector pin-out
- Support read/write cache allocation by policy
- Support up to 24 NVMe drives using PCIe switch
- Redundant flash image for adapter availability
- UBM, SES2, SMP and SGPIO enclosure management
- Support up to (512) 12Gb/s SAS, SATA or SSD drives using SAS expanders
- Support optional cache backup module (CBM) protection using SuperCap
- Tri-mode interface at each drive ports-12Gb/s SAS/SATA/ Gen 4.0 PCIe (NVMe)
- Controller level hardware encryption and self-encryption drive management
- Support RAID 1 - Multi Mirroring and Mirrored Pass-Through Disk
- Multiple RAID 0 and RAID 10 (1E) support (RAID 00 and RAID100)
- Broad operating support including Windows, Linux, FreeBSD, macOS and VMware
- RAID Levels - 0, 1, 3, 5, 6, 10, 30, 50, 60, Single Disk or JBOD
