HPE 875151-B21 Overview

The HPE 875151-B21 DL180 Gen10 8 to 16SFF Hot-Plug Drive Cage Upgrade Kit (often listed as “DL180 Gen10 8→16 SFF FIO upgrade kit” or simply 875151-B21) is a factory or field-installable drive-cage upgrade option that expands HPE ProLiant DL180 Gen10 small-form-factor (SFF) chassis capacity from eight front-access SFF drive bays to sixteen SFF hot-plug bays. This kit is designed for organizations that need higher front-panel density for SAS/SATA small-form-factor HDDs or SSDs while keeping serviceability and hot-swap maintenance intact. The kit is an OEM HPE option and is referenced in HPE DL180 Gen10 option listings and QuickSpecs.

Key features and benefits

Increased front-bay density

The principal advantage of the 875151-B21 upgrade is expanding the number of front hot-plug SFF bays available to the system from 8 to 16. For data-centre operators this translates into greater raw capacity per 2U chassis without migrating to a larger form factor or adding external JBODs, reducing rack space and cabling overhead.

Field-Installable Option (FIO) design

The 875151-B21 is listed as a field-installable option (FIO) for DL180 Gen10, meaning it can be ordered as a factory integrated option or installed later in the field by trained technicians. FIO status signals that the kit includes the mechanical and enablement parts required to convert an 8-bay chassis to 16-bay operation.

Compatibility

When upgrading drive density, ensure the chosen HPE Smart Array or third-party HBA supports the additional drive connections and lanes. HPE QuickSpecs and the DL180 Gen10 option documentation note complementary cable kits and enablement parts (for example, Smart Array P816i-a cable kits) that may be required depending on your storage controller selection. Some enablement kits provide the necessary SAS/SATA routing from the new front cage to the internal controller.

Compatibility

Server models & factory options

The 875151-B21 is explicitly tied to the HPE ProLiant DL180 Gen10 family and listed among DL180 Gen10 field and factory integration options. Before ordering, confirm that your chassis is a Gen10 DL180 model and consult the server’s QuickSpecs/option list for supported configurations. HPE documentation and product pages list 875151-B21 as the 8→16 SFF FIO kit for DL180 Gen10.

Controller & cable dependencies

Some controller options (for example, P816i-a or Smart Array controllers specific to Gen10) require separate cable kits for full front-bay connectivity. If your controller is a Smart Array P816i-a or E208i-a/P408i-a family member, consult the compatible cable kit part numbers (for example: P37221-B21 / P37790-B21 references in DL180 docs) before completing the upgrade. Missing cable kits will limit drive connectivity or require additional field cabling.

Drive form-factor & interface support

The upgrade is for SFF (2.5") SAS/SATA hot-plug drives. It is not a dedicated NVMe backplane kit; if you plan to use NVMe U.2 drives or NVMe on-board options, validate NVMe support with HPE documentation or the chosen controller. When using mixed drive types (e.g., SSD cache + HDD capacity), ensure the controller’s RAID and firmware support hybrid configurations.

Performance

Capacity vs. IOPS trade-offs

Expanding from 8 to 16 SFF allows significantly greater aggregate capacity in the same 2U chassis footprint. However, more drives can place greater demands on the controller’s queue depth and on bus bandwidth. Consider:

• For latency-sensitive workloads, favor SSDs or mixed-tier designs and ensure the RAID controller can deliver the required IOPS.
• For cold-storage or bulk archival, high-capacity 2.5" HDDs installed across 16 bays can maximize density economically.
• For caching tiers, use a small number of high-performance NVMe devices (if supported) or enterprise SATA/ SAS SSDs in combination with capacity HDDs.

Thermal & acoustic impacts

Doubling the number of bay locations can increase internal heat load if populated. Check fan speeds, server inlet temperatures, and any HPE-recommended thermal profiles after populating the cage. In tightly packed racks, confirm the ambient temperature requirements and consider staggered drive spin-up to avoid large inrush current and thermal spikes.
