Frequently Asked Questions
What is the primary function of the HPE 870549-B21 SAS Expander in a DL380 Gen10 server? +
The HPE 870549-B21 SAS Expander card allows your DL380 Gen10 server to support a higher drive count by expanding the connectivity of your existing SAS controller. It acts as a bridge, enabling the internal storage controller to manage additional hard drives or solid-state drives beyond the standard port limitations of the base backplane configuration.
Is the HPE 870549-B21 compatible with all HPE Gen10 server models? +
This specific SAS expander is designed primarily for the HPE ProLiant DL380 Gen10 series. While it integrates seamlessly within these chassis, compatibility often depends on your existing server configuration, such as the specific backplane type and storage controller installed. We recommend verifying your system's current drive cage setup to ensure it meets the required infrastructure for this expansion card.
Does the 870549-B21 SAS Expander affect storage performance? +
This expander card is engineered to support 12Gb/s SAS performance, ensuring that your data throughput remains consistent even when scaling up your storage capacity. Because it utilizes high-speed SAS lanes, it maintains the necessary bandwidth for enterprise-grade applications, preventing bottlenecks when you add extra drives to your server environment.
How does this SAS Expander manage connectivity to the drive backplane? +
The 870549-B21 connects directly to the server's storage controller and the drive backplane via internal SAS cables. It manages the signaling and distribution of data across the expanded array of drives. This centralized management ensures that the server's primary storage controller can communicate effectively with all connected physical disks as if they were part of a single, unified storage subsystem.
What are the common deployment scenarios for the HPE 870549-B21? +
This card is ideal for IT environments requiring high-density storage within a single 2U rack space. It is frequently deployed in data centers where businesses need to maximize the drive-holding capacity of their DL380 Gen10 servers for large-scale virtualization, database management, or file storage tasks that exceed the standard front-facing drive limitations.
Are there specific licensing requirements to enable this SAS Expander? +
Typically, hardware-based SAS expanders like the 870549-B21 do not require additional software licenses to function once installed. The storage controller identifies the hardware at the BIOS level during the server boot process. Ensure your server's firmware is updated to the latest version to maintain optimal communication between the controller, the expander card, and your storage media.
What is the physical installation process for this card in a DL380 Gen10? +
Installation requires inserting the card into the dedicated storage controller slot or the specified internal riser slot designed for this component. Once seated, you must route the internal SAS cables from the card to the server backplane. Proper cable management is essential to maintain airflow within the chassis, which is critical for the thermal health of the Gen10 server components.
How does the 870549-B21 impact the overall reliability of the storage subsystem? +
Designed to HPE enterprise standards, this SAS expander provides a robust connection point for your storage drives. By reducing the number of direct cables required to reach individual drive bays, it simplifies the internal architecture, which can lead to better airflow and more stable data paths, ultimately enhancing the long-term reliability and serviceability of your server’s internal storage stack.
