## Summary description

The QNAP QXP-820S-B3408 is an internal SAS interface card with a PCI Express host interface. It features a low-profile form factor and supports a maximum data transfer rate of 12 Gbit/s. With one fan for cooling, this wired connectivity solution is ideal for enhancing your system's performance. The card is designed for fiber interface connectivity, making it a reliable choice for data-intensive applications.

## Long description

The SAS HBA PCIe Expansion Card increases a QNAP NAS storage capacity by connecting it to TL SAS JBOD storage enclosures and REXP expansion units. It supports daisy-chaining multiple expansion units via mini SAS HD cables to scale total disk capacity up to 4.6PB, enabling SAS-based storage for virtualization, surveillance, Big Data, video editing and broadcast workflows.
Advantages
Supports high-performance, high-availability SAS drives with lower latency and improved IOPS compared with SATA. Each SAS port aggregates four 12Gb/s SAS channels, offering up to 48Gb/s per host connection. The card allows flexible port configuration for multipath or link aggregation to balance data transfer loads and reduce risk of service interruptions or backup failures.
Key specifications
Interface: PCIe SAS HBA
SAS channel per port: 4 × 12Gb/s (up to 48Gb/s per host connection)
Expansion support: Daisy-chain up to 16 devices (TL SAS JBOD and REXP units)
Maximum total capacity (example): Up to 4.6PB using 18TB drives in sixteen 16-bay enclosures
Connections: Mini SAS HD cables for chaining expansion units
How to use
Install the SAS HBA card into an available PCIe slot on the QNAP NAS and connect the card to TL SAS JBOD or REXP expansion units using high-speed mini SAS HD cables. Configure the NAS to recognize the expansion units, then set up multipath or link aggregation as required to distribute data transfer loads and improve redundancy. Verify connectivity and perform a backup or test transfer to confirm correct operation.
Recommendations
Use enterprise-grade SAS drives for best performance and reliability, plan the daisy-chain topology to keep cable lengths within recommended limits, and configure multipath or link aggregation to maintain uninterrupted services and reliable backups.
