SAS Expander module HP Enterprise for ML350 Gen10 12Gb

SAS Expander module HP Enterprise for ML350 Gen10 12Gb is a server component designed to increase internal SAS connectivity on HP Enterprise ProLiant ML350 Gen10 systems. The module supports 12Gb/s SAS links and enables additional internal drives and external enclosures to be connected through the server’s existing storage subsystem. It is intended for installations requiring scalable drive counts, improved aggregation of storage devices, and simplified cabling within rack or tower server environments.

Advantages

The SAS Expander module provides increased port density without requiring additional host bus adapters, allowing administrators to attach more SAS drives and JBOD enclosures. By supporting 12Gb/s SAS signaling it maintains compatibility with modern high-performance drives and improves throughput potential where backplanes and controllers also support that speed. The module helps centralize storage connections, reducing cable complexity and enabling more flexible storage configurations within the ProLiant ML350 Gen10 platform.

Suitable for

• Expanding internal drive capacity in HP ProLiant ML350 Gen10 servers
• Connecting additional SAS JBOD enclosures to a single server
• Data center servers requiring higher drive counts for file, block, or backup storage
• Enterprise deployments needing simplified cabling and drive aggregation

Key specifications

• Brand: HP Enterprise
• Model compatibility: ProLiant ML350 Gen10
• SAS signaling: 12Gb/s
• Manufacturer part number (MPN): 874576-B21-RFB
• Function: SAS expander module to increase internal/external drive ports

How to use

Install the SAS Expander module into the appropriate expansion slot or bay as specified by the ProLiant ML350 Gen10 hardware installation guide. Ensure the server is powered down and that you follow electrostatic discharge (ESD) precautions. After physical installation, connect the module to the server backplane or SAS controller using compatible SAS cables, and attach additional drives or enclosures as required. Power on the server and verify that the expander and attached drives are detected in the system firmware (iLO/BIOS) and by the operating system or storage controller utilities. Update firmware if necessary to ensure compatibility between controller, backplane and expander.

Usage recommendations

Use certified HP Enterprise cables and compatible SAS controllers/backplanes rated for 12Gb/s to achieve optimal performance. Confirm firmware versions across controller, expander and drives are current and supported by HP documentation. For high-availability deployments, plan drive and enclosure layouts to maintain redundancy and consider airflow and cooling requirements inside the chassis.
