HPE DL340 G12 Front GPU 8SFF X4 DAC - P75772-B21

HPE P75772-B21 Front GPU 8SFF x4 DAC Cable Kit for ProLiant DL340 Gen12

Overview

The HPE P75772-B21 is a front GPU enablement kit designed for the HPE ProLiant DL340 Gen12 server platform. It provides the x4 Direct Attach Copper (DAC) interconnect and 8 SFF drive bay front configuration needed to add GPU compute capacity to a DL340 G12 chassis — a targeted option when you are expanding AI inference, video analytics, or GPU-accelerated workloads within an existing DL340 G12 deployment without a full platform swap.

This kit ships from the factory at 0.84 lb, making it a lightweight internal cabling and bracket assembly. Sourced factory-new as a genuine HPE option kit, the P75772-B21 (often searched as P75772 B21) is the manufacturer-designated path for adding front GPU support to this specific server generation — using aftermarket or third-party alternatives risks mechanical incompatibility with the DL340 G12 chassis tolerances and HPE's support coverage for the platform.

Key Features

• Platform-specific fit: Engineered exclusively for the DL340 Gen12 chassis. The front GPU 8SFF x4 DAC configuration integrates directly with the DL340 G12 backplane and front bay layout — no modification or adapter bridging required, which matters in dense rack environments where re-cabling costs labor time.
• x4 DAC interconnect: Direct Attach Copper provides a low-latency, short-reach internal signal path from the front drive bay region to the GPU riser, avoiding the overhead of active optical or re-timed links for an intra-chassis run.
• 8 SFF bay support: Retains access to small form-factor drive bays at the front of the chassis alongside the GPU configuration — relevant when you need both NVMe/SAS storage density and GPU acceleration in the same 1U or 2U footprint.
• Factory-new genuine HPE: Supplied as a genuine HPE option kit — no grey-market, no parallel imports — which matters for maintaining ProLiant warranty coverage and HPE support agreements on the host server.

Integration & Compatibility

The P75772-B21 is validated for the HPE ProLiant DL340 Gen12 server. Before ordering, confirm your chassis generation and existing riser configuration against HPE's QuickSpecs for the DL340 G12 — mixing Gen11 and Gen12 internal option kits is a known source of fitment failures. Consult the HPE server accessories catalog for companion GPU risers and compute platforms suited to video analytics workloads. If you are planning GPU-accelerated camera analytics at scale, pair this with a review of your IP camera pipeline and PoE switch infrastructure feeding the server.

Frequently Asked Questions

Q: Which server is the P75772-B21 compatible with?

A: The P75772-B21 is designed for the HPE ProLiant DL340 Gen12 (G12). It is not validated for earlier DL340 generations or other ProLiant families — verify your chassis part number before ordering.

Q: What does the x4 DAC designation mean for this kit?

A: x4 DAC refers to a four-lane Direct Attach Copper cable, used as the internal interconnect between the front GPU bay assembly and the server's riser or backplane. It is a passive, short-reach copper link suited to intra-chassis distances.

Q: Does the P75772-B21 include a GPU?

A: No. This is a front bay enablement and cabling kit — it provides the mechanical and signal pathway to support a front-mounted GPU option. The GPU itself is a separate line item.

Q: What is the weight of this kit?

A: The P75772-B21 weighs 0.84 lb, consistent with a cabling and bracket assembly rather than an active compute component.

Q: Is this kit factory-new?

A: Yes. The P75772-B21 is supplied as a genuine, factory-new HPE option kit — no refurbished or grey-market units.

Marty Allison

The P75772-B21 is one of those kits that looks simple on a spec sheet — 0.84 lb, a DAC cable and bracket assembly — but gets costly to work around if you order the wrong generation. I have seen DL340 G11 kits arrive on G12 chassis and the front bay panel simply does not seat. Confirm your server's generation from the iLO system summary or the physical chassis label before requisitioning this part.

Technical Highlights:

• Weight (0.84 lb): Bracket-and-cable assembly mass — confirms this is passive hardware with no active components to fail or configure, which simplifies spare-parts logistics for field support teams maintaining multiple DL340 G12 nodes.
• x4 DAC interconnect: Passive copper at intra-chassis distances avoids the latency jitter and power overhead of active optical links — the right call for a GPU-to-backplane run measured in centimeters, not meters.
• 8 SFF front bay retention: Preserves drive bay access alongside GPU enablement, so you do not have to choose between NVMe storage density and accelerator capacity in the same 1U/2U slot.

Deployment Considerations:

• Validate the DL340 G12 QuickSpecs PDF against your chassis serial before ordering — HPE option kit compatibility is generation-locked and the part numbers between G11 and G12 are visually similar.
• This kit enables the GPU bay path but does not include the GPU or riser card — budget those as separate line items and confirm riser slot availability in your specific DL340 G12 configuration.

Best fit: DL340 Gen12 deployments adding GPU-accelerated video analytics or AI inference nodes where NVMe storage must coexist with front GPU capacity in a space-constrained rack.
