– The UK’s Areca RAID Experts!The Areca ARC-1886-4X12I is a PCIe Gen 4.0 tri-mode RAID adapter configured with 12 internal and 4 external drive ports for mixed SAS/SATA and NVMe deployments.
It combines a dual-core ROC processor, on-board ECC cache and broad management and OS support to address demanding database and enterprise storage use cases.
The adapter uses a Tri-Mode Dual Core ARM A15 1.6GHz ROC and presents a Host Bus Interface of 8-Lane PCI Express® 4.0 to the system.
On-board cache is 8GB DDR4-2666 SDRAM with ECC protection and the adapter supports the optional ARC-1886-CBM cache backup module for SuperCap-based protection.
The ARC-1886-4X12I offers 12 internal and 4 external ports with drive connectors consisting of 2 x SFF-8654 [x8] and 1 x SFF-8644 [x4].
The adapter supports up to 512 12Gb/s SAS or 6Gb/s and 3Gb/s SAS/SATA HDDs/SSDs using 12Gb/s SAS expanders and up to 32 NVMe drives through the PCIe switches.
Each drive port supports tri-mode operation with data transfer rates up to 12Gb/s SAS/SATA or Gen 4.0 PCIe (NVMe) per port.
Supported RAID levels include 0, 1, 3, 5, 6, 10, 30, 50, 60, single disk and JBOD. Additional features include RAID 1 multi-mirroring, mirrored pass-through disk, configurable stripe sizes up to 1MB, write-through or write-back cache, online RAID level/stripe size migration, online capacity expansion and support for global and dedicated hot spares.
Management is available via McRAID Storage Manager (web-based GUI), McRAID Utility, command-line tools, CIM provider for VMware and McBIOS configuration utility. Host Interface options include NVMe Mode with OS-native NVMe driver and Areca Legacy Mode supporting Microsoft Windows, Red Hat/CentOS, SUSE, Fedora, Debian, Ubuntu, FreeBSD, XenServer, unRAID, macOS and VMware ESXi.
Physical options include Low Profile and full-height mounting dimensions and the adapter consumes approximately 14 Watts. It operates from 0 °C to 60 °C at 10% to 85% non-condensing humidity.
The adapter provides redundant flash image for availability, supports UBM/SES-2/SGPIO enclosure management, and includes features such as S.M.A.R.T., automatic drive insertion/removal detection and rebuilding, and controller-based hardware encryption with SED support.
