ARC-1886-xNxI PCIe Gen 4.0 M.2 NVMe Hardware RAID adapter is built to deliver unprecedented performance, using only carefully, best-in-class components. These include the dual core Broadcom SAS3916, PCIe Gen 4.0 tri-mode ROC, 8GB DDR4-2666 SDRAM with ECC protection.

At the heart of ARC-1886-xNxI is the incredibly powerful Broadcom SAS3916 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-1886-xNxI hardware RAID relieves the parity generation burden from the host and maximizes application processing performance.

With a massive 8GB of DDR4-2666 SDRAM, ARC-1886-xNxI gives you super-smooth multitasking during the period of high overload in 4K environment. ARC-1886-xNxI firmware can configure how much cache SDRAM dedicated for read, and how much for write. If your server application has significantly more reads than writes or more writes than reads, you might need to change this setting to adjust the read/write cache ratio for improving performance. Big cache is the perfect choice for a 4K application drive, making your professional apps work as fast as possible.

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

The ARC-1886-xNxI RAID adapter can operate in all three modes concurrently servicing NVMe, SAS or SATA drives that offers the operation of NVMe, SAS or SATA storage devices in a single RAID adapter. With a single ARC-1886-xNxI RAID adapter, system integrators can take full advantage of 6x PCIe Gen 4.0 M.2 x2/x4 NVMe drives (or 6Gb/s M.2 SATA SSD drives) and 2x 12Gb/s SAS/SATA ports.

NVMe disasters always happen unexpectedly, and without proper safeguards your data could be in jeopardy. Implementing an Auto-backup and Recovery strategy is critical for protecting a NVMe array from the corruption of data and for providing the ability to recover that data.The ARC-1886-xNxI provides a dual disk arrays including a NVMe disk array and a hard disk array. The RAID firmware has a preset value, and when the workload size does not reach the preset value, it backs up the data of M2 NVMe disk array to the SATA connector port hard disk array. This has the advantages of fast access to data by the NVMe disk and high reliability of data storage on the hard disk. These backups contain exact copies of NVMe array. The clone SAS/SATA array uses them for disaster recovery purposes.

An enterprise storages need to ensure data integrity in the event of power losses and system crashes. The Power Loss Protection (PLP) is a hardware and firmware solution on the ARC-1886-xNxI RAID adapter to ensure that the NVMe SSDs integrity is maintained should a power loss event occur.

Launch the web browser-based MRAID storage manager to check the power loss event.

ARC-1886-xNxI RAID storages have integrated caches for increasing performance. With corresponding protective mechanisms, the content of these unwritten cached data in the SDRAM would be lost when there is a complete AC power failure or a brief unexpected power outage. For that reason, a cache backup module (CBM) protects the integrity of the cached data on ARC-1886-xNxI RAID adapter by providing backup power. The cache backup module has built-in functionality to charge the supercapacitor pack automatically and to communicate supercapacitor pack status information to the RAID adapter.

Areca provides more flexible management tools comparing with others competitors to manage and monitor ARC-1886-xNxI RAID adapter.

Lets you set up and manage RAID storage through Out-of-band web browser manager and ArcSAP utility

The ARC-1886-xNxI also offers an alternative out-of band method d for McRAID storage manager. User can access the built-in configuration without needing the ArcHTTP proxy server on the host system. The ARC-1886-xNxI has an RJ-45 connector out-of-band management port on the rear. You can monitor and manage an ARC-1886-xNxI RAID adapter using this dedicated management channel to manage the ARC-1886-xNxI RAID adapter without any host connection. It will also not disturb the host access when you monitor or manage the ARC-1886-xNxI RAID adapter.

Lets you set up and manage RAID storage through In-band web browser manager and ArcSAP utility

You can configure in-band management for communication to travel over the PCIe bus path between a data host and ARC-1886-xNxI RAID adapter. In-band management uses a proxy agent HTTP management software (ArcHTTP) running on a data host to communicate with an ARC-1886-xNxI RAID adapter.

McRAID storage manager is firmware-based utility, which is accessible via the web browser installed on your operating system. The web browser-based McRAID storage manager is a HTML-based application, which utilizes the browser (Safari, IE and Mozilla etc) installed on your monitor station. It can be accessed through the in-band Thunderbolt bus and out of band Ethernet port. The in-band-Thunderbolt bus method can launch the web browser-based McRAID storage manager via ArcHTTP proxy server.
