The SAS HBA PCIe expansion card is designed to expand 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 using high-speed Mini-SAS HD cables to increase the total hard disk storage capacity to up to 4.6 PB, meeting growing storage demands. SAS-based storage solutions help businesses create highly reliable IT environments for virtualization, surveillance, big data, video editing, and TV broadcast storage.
Use powerful and highly available SAS drives. Compared to SATA, SAS enables low-latency, energy-efficient, and IOPS-optimized storage capabilities. Each SAS port combines four 12 Gb/s SAS channels, providing up to 48 Gb/s per host connection.
Expand your total hard disk storage capacity to up to 4.6 PB. A 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 offers the potential to store up to 4.6 PB (calculated with 18 TB drives in sixteen 16-bay enclosures).
Achieve faster backups and uninterrupted services with flexible port configuration. SAS expansion cards can be flexibly configured to meet various application needs. By managing multipath or link aggregation between the NAS and expansion units, data transfer loads are effectively balanced, allowing you to avoid interruptions in system services and backup failures.
