ARC-1886-8X8I
8-Port Internal/External PCIe Gen 4.0 Tri-Mode Hardware RAID Adapter
1x Internal SlimSAS (SFF-8654 8i) Port
2x External MiniSAS HD (SFF-8644) Ports
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.
