HPE DL325 G11 8SFFX4 NVME SR932P SL2 CA - P57005-B21

HPE P57005-B21 NVMe 8SFF Drive Cage Cable Assembly for ProLiant DL325 Gen11

Overview

The HPE P57005-B21 is a factory-new NVMe drive cage cable assembly engineered for the HPE ProLiant server platform, specifically the DL325 Gen11. Identified by UNSPSC code 43211600 (computer storage devices and media), this cable kit connects the 8SFF (small form factor) NVMe drive bays to the SR932p controller via the SL2 backplane path — enabling direct NVMe-attached storage in a density-optimized 2U configuration. If you are building out an enterprise server with all-flash NVMe storage, the P57005-B21 is the HPE-specified internal cable required to wire that topology correctly.

Key Features

• NVMe Interface: Direct NVMe connectivity bypasses the SAS/SATA translation layer, delivering the full bandwidth headroom of PCIe-attached storage — critical for latency-sensitive workloads like databases, VMs, or AI inference pipelines running on the DL325 Gen11.
• 8SFF Bay Support: Routes all eight small form factor drive positions through a single cable assembly, keeping the internal airflow path clear and simplifying installation compared to point-to-point cabling.
• SR932p Controller Pairing (SL2 path): Matched specifically to the HPE Smart Array SR932p controller on the SL2 cable route — using a non-matched cable risks signal integrity issues or outright non-recognition by the controller firmware.
• Lightweight at 0.25 lb: At a quarter pound, the cable assembly adds negligible weight to the chassis — relevant if you are shipping pre-configured servers or are close to rack weight limits in a dense deployment.
• Multi-Origin Manufacturing: Sourced across HPE's global supply chain (CN, CZ, JP, MX, SG), consistent with HPE's standard commercial manufacturing footprint for server accessories.

Integration and Compatibility

The P57005-B21 (often searched as P57005 B21) is specified for the HPE ProLiant DL325 Gen11 platform in the 8SFF NVMe configuration with the SR932p storage controller. Before ordering, confirm your chassis option kit, backplane revision, and controller SKU against HPE's server compatibility matrix — cable routing in the DL325 Gen11 varies by drive bay configuration and controller tier. Pairing with an incompatible backplane or controller will prevent the storage subsystem from initializing correctly. Review HPE's server accessories and cable kits for the full DL325 Gen11 storage build-out options.

Frequently Asked Questions

Q: What server is the P57005-B21 designed for?

A: The P57005-B21 is designed for the HPE ProLiant DL325 Gen11 server in the 8SFF NVMe drive configuration with the SR932p Smart Array controller.

Q: What interface does the P57005-B21 use?

A: NVMe — this is a direct PCIe-attached NVMe cable assembly, not a SAS or SATA cable.

Q: Can the P57005-B21 be used with older HPE server generations?

A: The evidence only confirms compatibility with the DL325 Gen11. Cross-generation use is not supported by available documentation and is not recommended without verifying HPE's compatibility matrix for your specific chassis and controller.

Q: How heavy is the P57005-B21?

A: 0.25 lb — a lightweight internal cable assembly.

Marty Allison

The P57005-B21 is the kind of SKU that stalls a server build if you miss it — it is the specific NVMe cable assembly that connects the 8SFF drive bays to the SR932p controller on the SL2 path in the DL325 Gen11. Miss it or substitute the wrong cable, and the controller will not see your drives regardless of how the rest of the storage stack is configured.

Technical Highlights:

• NVMe Interface: PCIe-direct path eliminates SAS/SATA overhead — the right architecture for all-flash NVMe deployments where storage latency matters.
• 8SFF Coverage: A single assembly covers all eight small form factor bays, reducing internal cable clutter and keeping the air path open in a dense 2U chassis.
• 0.25 lb Weight: Negligible mass for a cable kit — relevant for pre-configured system shipping and rack weight compliance in high-density builds.

Deployment Considerations:

• Verify your DL325 Gen11 chassis option and backplane revision before ordering — HPE offers multiple cable routes depending on drive bay configuration and controller tier; this part is specific to the SR932p on the SL2 path.
• Available evidence covers interface type and weight only; for full pinout, bend-radius, and controller firmware compatibility, consult HPE's QuickSpecs for the DL325 Gen11 before committing to a storage topology.

The P57005-B21 is the correct part for DL325 Gen11 builds targeting maximum NVMe drive density with the SR932p controller — particularly relevant in edge compute or video analytics server configurations where all-flash storage is paired with GPU-accelerated inference workloads.
