The SAS HBA PCIe Expansion Card is designed for expanding the capacity of a QNAP NAS by connecting it to TL SAS JBOD storage enclosures and REXP expansion units. Multiple expansion units can be daisy-chained via high-speed mini SAS HD cables to expand the total disk capacity up to 4.6PB to meet growing data storage needs. SAS-based storage solutions can assist businesses in creating highly-reliable IT environments for virtualization, surveillance, Big Data, video editing and TV broadcast storage.Use high-performance and high-availability SAS drivesCompared with SATA, SAS enables low-latency, power-efficient, and IOPS-optimized storage capabilities. Each SAS port combines four 12Gb/s SAS channels, delivering up to 48Gb/s per host connection.Expand your total disk capacity up to 4.6PBA NAS with a SAS expansion card can be daisy-chained with up to 16 devices, including TL SAS JBOD storage enclosures and REXP expansion units. This provides to potential to store up to 4.6PB (calculated using 18TB drives in sixteen 16-bay enclosures).Attain faster backup and uninterrupted services with flexible port configurationSAS expansion cards can be flexibly configured to fit various usage applications. By managing multipath or link aggregation with NAS to expansion units, data transfer loads are effectively balanced, and you can avoid interrupting system services and prevent backup failures.

QDA-SA32.5-inch 6Gbps SAS to SATA drive adapter (Designed for dual-controller all-flash ES2486dc NAS)The QDA-SA3 adapter is designed for QNAP’s dual-controller all-flash array Enterprise ZFS NAS (ES2486dc) and allows the usage of a SATA 6Gbps drive in a 2.5-inch SAS 12Gbps/6Gbps drive bay — providing the ability to expand storage capacity with cost-effective SATA drives.SAS dual-port advantage for fault toleranceSAS features dual porting for redundancy, eliminating single points of failure and allowing for higher reliability and performance. By installing a SATA drive with the QDA-SA3 into a dual-controller all-flash Enterprise ZFS NAS, the SATA drive can share these SAS dual-port advantages to ensure a high-availability, fault tolerant enterprise storage environment.Designed for all-flash Enterprise ZFS NASThe QDA-SA3 can be easily installed in the 2.5-inch disk tray of an all-flash array Enterprise ZFS NAS (ES2486dc disk tray model: TRAY-25-NK-BLK04).
