QNAP QXP-820S-B3408 - 2-port miniSAS host bus adapter

The QNAP QXP-820S-B3408 2-Port miniSAS HBA acts as a storage controller for servers and network-attached workstations. This expansion card connects external drive enclosures to host systems that require more capacity than internal ports can provide. It facilitates external data links, providing the throughput needed for server-based storage tasks, such as backups or database management, by connecting the server to its expansion units.

The card features a compact design suitable for high-density server racks and slim workstations. An integrated fan regulates airflow over the controller during operation, preventing heat build-up in enclosed chassis during heavy use. The card installs into a standard motherboard expansion slot and includes a metal mounting bracket for support. It connects to drives using external cables that meet industry SAS standards.

• 12 Gbit/s transfer rates: supports high-bandwidth SAS communication.
• Dual external ports: allows simultaneous connection of two storage units via miniSAS.
• 260 g unit weight: lightweight design to minimize motherboard strain.
• Integrated cooling fan: provides active heat dissipation for continuous operation.
• PCI Express host interface: uses the standard system bus for installation.
• Low-profile format: ensures compatibility with both slimline and standard server chassis.
