HPE DL560 G11 LC 8SFF X4 NVME B1 4P DAC - P61767-B21

HPE P61767-B21 ProLiant DL560 Gen11 8SFF x4 NVMe Bay 1 4-Port DAC Option Kit

The HPE P61767-B21 is a storage connectivity option kit designed specifically for the HPE ProLiant DL560 Gen11 server platform. Configured for eight small form factor (8SFF) drive bays with an x4 NVMe interface over a four-port direct attach cable (DAC) arrangement in Bay 1 position, this kit extends the DL560 Gen11's NVMe storage fabric — relevant in high-density compute deployments where low-latency, high-bandwidth storage is a priority and every microsecond of I/O access time affects workload throughput. If you're building out a DL560 Gen11 with NVMe-based all-flash or hybrid storage, the P61767-B21 (often searched as P61767 B21) is the specific option part to match your bay configuration.

Key Features

• NVMe Interface: Direct NVMe connectivity bypasses the legacy SAS/SATA protocol stack, delivering significantly lower latency than traditional storage interfaces — important for database, analytics, and real-time surveillance recording workloads where queue depth and random I/O performance are bottlenecks.
• 8SFF Drive Bay Support: Accommodates eight small form factor drives in a dense configuration, giving the DL560 Gen11 the storage slot density needed for high-capacity NVMe deployments without consuming disproportionate rack space.
• x4 NVMe / 4-Port DAC Architecture: The four-port direct attach cable design routes NVMe lanes directly from the drive backplane to the server's PCIe fabric — minimizing signal path complexity and supporting the full bandwidth potential of modern NVMe SSDs.
• Bay 1 Position-Specific: Engineered for the Bay 1 slot on the DL560 Gen11 chassis. Correct bay-position matching is required for proper backplane alignment, cable routing, and platform firmware recognition — ordering the wrong bay variant causes compatibility failures that require physical re-cabling.
• Platform-Native Design: As a genuine HPE option kit, it integrates with HPE's iLO management and storage configuration utilities, supporting the platform's hardware monitoring and predictive failure alerting without requiring third-party drivers or workarounds.

Integration & Compatibility

The P61767-B21 is validated for the HPE ProLiant server line, specifically the DL560 Gen11 platform. It is not a universal or cross-generation part — confirm your chassis generation and bay position before ordering. NVMe drive compatibility should be verified against HPE's SPP (Service Pack for ProLiant) and the DL560 Gen11 QuickSpecs for supported SSD models. This kit is one component in a broader server storage architecture; pair it with compatible HPE NVMe SSDs and ensure your system's PCIe lane budget supports the additional storage fabric load. For deployments routing NVMe storage to support high-channel network video recorders or AI inference workloads, validate that your storage controller and BIOS revision support the drive count and NVMe namespace configuration you intend to run.

Frequently Asked Questions

Q: What server platform is the P61767-B21 designed for?

A: The P61767-B21 is designed specifically for the HPE ProLiant DL560 Gen11 server. It is not a cross-generation or universal part — verify your chassis generation before ordering.

Q: What interface does the P61767-B21 use?

A: It uses an NVMe interface via a four-port direct attach cable (DAC) configuration, connecting the 8SFF drive backplane directly to the server's PCIe fabric for low-latency storage access.

Q: Does the P61767-B21 work in any bay position on the DL560 Gen11?

A: No. This kit is specifically configured for Bay 1. Ordering the incorrect bay variant will result in physical and firmware incompatibility. Confirm your target bay position before purchasing.

Q: How many drives does the P61767-B21 support?

A: The kit supports eight small form factor (8SFF) drives in the NVMe bay configuration for the DL560 Gen11.

Q: Is the P61767-B21 compatible with third-party NVMe drives?

A: HPE platform option kits are validated against HPE's supported drive list. Third-party NVMe drive compatibility should be verified against the DL560 Gen11 QuickSpecs and HPE's Service Pack for ProLiant (SPP) documentation before deployment.

Karl Wilson

The P61767-B21 is a position-specific NVMe bay option kit for the DL560 Gen11 — and that word "position-specific" is where I see integrators trip up most often. Bay 1 placement dictates cable routing, backplane alignment, and how iLO reports the storage fabric. Getting the wrong bay variant means a physical re-cabling job in a dense 4-socket chassis, which nobody wants to discover during a commissioning window.

Technical Highlights:

• NVMe Interface: Bypasses SAS/SATA protocol overhead entirely — for workloads with high random I/O demand (real-time video analytics, AI inference staging, high-channel recording buffers), this is the correct storage path, not a nice-to-have.
• 8SFF Bay Density: Eight small form factor slots in a single bay group gives the DL560 Gen11 the drive count to support all-NVMe configurations without requiring additional expansion shelves in the rack.
• 4-Port DAC Architecture: Direct attach means no HBA in the signal path for basic NVMe access — fewer components, fewer failure points, and full PCIe bandwidth available to the connected SSDs.

Deployment Considerations:

• Verify your DL560 Gen11 chassis revision and firmware SPP level before installing — HPE option kits require matching platform generations and current SPP for iLO storage monitoring to function correctly.
• The four-port DAC consumes PCIe lanes directly from the platform's fabric; plan your lane budget against other installed option cards before committing to drive count and controller configuration.

This kit is the right call for DL560 Gen11 deployments running NVMe-backed workloads in Bay 1 — specifically high-channel video recording servers, AI inference nodes, or dense database appliances where storage latency is a first-order constraint, not an afterthought.
