Kontrolery ARECA ARC-1886-xNxI prezentują zaawansowaną, sprzętową technologię RAID o zwiększonej wydajności dzięki wykorzystaniu 6 lub 4 zatok M.2 NVMe i ulepszonej ochronie danych korporacyjnych dzięki wykorzystaniu dwóch portów SAS/SATA.
Sprzętowy adapter RAID uzyskuje dostęp do danych macierzy dyskowej NVMe z zadaną wartością obciążenia. Podczas gdy poziom obciążenia pozostaje w zakresie zadanej wartości, adapter RAID stale tworzy kopie zapasowe danych macierzy dyskowej NVMe na pozostałych dwóch macierzach dysków twardych z portami SAS/SATA. Urządzenia wyposażone są w dwurdzeniowy procesor ROC 1,6 GHz, pamięć DDR4-2666 i interfejs hosta/urządzenia PCIe Gen 4.0 oraz obsługuje poziomy RAID 0, 1, 10, 3, 5, 6, pojedynczy dysk lub JBOD.
Areca ARC-1886-6N2I M.2 NVMe SAS/SATA RAID PCIe 4.0
Automatic backup between two arrays
NVMe disasters always happen unexpectedly, and without proper safeguards, data can be at risk. Implementing an automated backup and recovery strategy is critical to protecting NVMe arrays from data corruption and ensuring that data can be recovered. The ARC-1886-xNxI provides two disk arrays, including an NVMe disk array and an HDD array. The RAID firmware has a preset value, and when the workload size does not reach the preset value, it backs up the M2 NVMe disk array data to the SATA HDD array. This has the advantages of fast data access via NVMe and high reliability of data storage on the hard drive. These backups contain exact copies of the NVMe array. The cloned SAS/SATA array uses them for disaster recovery purposes.
Power Loss Protection (OMP)
Enterprise storage must ensure data integrity in the event of power loss and system failure. Power Loss Protection (PLP) is a hardware and firmware solution in the ARC-1886-xNxI RAID Adapter that ensures the integrity of NVMe SSDs is maintained in the event of a power loss.
