HPE DL385 G11 8SFF X1 Sas/sata PCIE CBL - P57848-B21

HPE P57848-B21 DL385 Gen11 8SFF SAS/SATA/PCIe Cable Assembly

Overview

The HPE P57848-B21 is an internal cable assembly designed specifically for the ProLiant DL385 Gen11 server in its 8 Small Form Factor (8SFF) drive-bay configuration. It routes SAS, SATA, and PCIe signal paths between the system backplane and the server's storage and expansion subsystems — a purpose-built component that ensures correct signal integrity and physical routing within the DL385 Gen11 chassis. If you're building out or expanding storage capacity on a DL385 Gen11 platform, this is the cable you need to connect the 8SFF backplane correctly.

Key Features

• Triple-Interface Support (PCIe, SAS, SATA): A single cable assembly handles PCIe, SAS, and SATA connections simultaneously, reducing the number of discrete cables inside the chassis and keeping airflow paths cleaner in a dense 1U/2U rack environment.
• Platform-Specific Fit: Engineered to HPE's exact routing and connector specifications for the DL385 Gen11 8SFF backplane — not a generic cable. Physical length (16.70 in) and connector placement match the chassis geometry, so there's no improvising or cable management gymnastics during installation.
• Genuine HPE Component: Factory-new, sourced through authorized distribution channels. Using the correct HPE part number matters here — off-spec cables in a production server risk backplane connector damage or intermittent drive faults that are difficult to diagnose after the fact.
• US-Sourced: Country of origin is the United States, relevant for procurement programs requiring domestic-origin components (TAA compliance verification should be confirmed separately with HPE for your specific contract vehicle).
• Manageable Physical Profile: At 1.50 lb and 16.70 × 8.60 × 3.40 in, the assembly is appropriately sized for the DL385 Gen11 form factor without excess bulk that would complicate routing in a populated chassis.

Integration & Compatibility

The P57848-B21 (often searched as P57848 B21) is validated for use in the HPE ProLiant DL385 Gen11 server with the 8SFF drive bay configuration. It is not interchangeable with DL385 Gen10 or Gen10 Plus cable kits — HPE revises internal routing and connector keying between generations, so always match the cable to the exact server generation. Verify your chassis option kit and backplane part number against HPE's DL385 Gen11 QuickSpecs before ordering if you're unsure which cable assembly your configuration requires. This cable is part of the broader HPE ProLiant server accessories ecosystem and pairs with HPE's server storage and expansion components.

Frequently Asked Questions

Q: Which server is the P57848-B21 compatible with?

A: The P57848-B21 is designed for the HPE ProLiant DL385 Gen11 server in an 8SFF (Small Form Factor) drive-bay configuration. It is not validated for Gen10 or Gen10 Plus variants.

Q: Does this cable support NVMe drives?

A: The cable supports PCIe, SAS, and SATA interfaces per the available specification data. NVMe compatibility depends on your specific backplane and DL385 Gen11 configuration — consult HPE's DL385 Gen11 QuickSpecs to confirm NVMe routing for your exact option kit.

Q: Is the P57848-B21 a factory-new component?

A: Yes. The P57848-B21 is supplied factory-new, sourced through distribution channels carrying genuine HPE parts — no refurbished or grey-market components.

Q: Can I use this cable in a DL385 Gen10 Plus chassis?

A: No. HPE revises internal connector routing between server generations. The P57848-B21 is specific to the DL385 Gen11 8SFF configuration. Using a cable from a different generation risks physical incompatibility or connector damage.
