Ultrafast Transfer Speed
Unprecedented Performance
ARC-1686-8I/8X PCIe Gen 4.0 Cost-Effective RAID Adapters is built to deliver unprecedented performance, using only carefully, best-in-class components. These include the dual core Broadcom SAS3908, PCIe Gen 4.0 and tri-mode ROC.
Powerful Broadcom Tri-mode ROC Engine
At the heart of ARC-1686-8I/8X is the incredibly powerful Broadcom SAS3908 dual-core ARM A15 tri-mode ROC, giving effortless performance as desirable. It delivers storage interface PCIe Gen 4 NVMe, 12Gb/s SAS, 6Gb/s SATA, and the security of data protection. Damage in a software RAID is considered as the consumption of massive computation and memory bandwidth on the host. The ARC-1686-8I/8X hardware RAID relieves the parity generation burden from the host and maximizes application processing performance.
High Bandwidth PCI-E 4.0 Support
To run the PCIe Gen 4.0 slots in Gen 4 speed, please must install the ROC which supports PCI Express 4.0. If you install the PCIe3.0 ROC, the PCI Express 4.0 slots will run only at Gen3 speed.
Higher bit rate - 16.0GT/s
Higher bandwidth per lane - 2GB/s
Higher efficiency - 98.5% encoding efficiency
8 Ports PCIe Gen 4.0 Cost-Effective RAID Adapters
The new generation ARC-1686-8I/8X family offers advanced technology for increased performance and improved enterprise data protection. They were designed with 1.6 GHz dual core ROC processor 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-1686-8I/8X cost-effective tri-mode RAID adapters can offer both PCIe Gen 4.0 host and 12Gb/s SAS/SATA/PCIe (NVMe) tri-mode storage interfaces.
