HPE DL560 GEN11 Ac/lc 8SFF SATA BOX3 DAC - P59141-B21

HPE P59141-B21 ProLiant DL560 Gen11 8SFF SATA Drive Cage

Overview

The HPE P59141-B21 is a SATA drive cage assembly designed for the HPE ProLiant DL560 Gen11 server platform. Configured as an 8 Small Form Factor (8SFF) bay cage in the BOX3 position, this component extends or replaces the drive backplane capacity within the DL560 Gen11 chassis — relevant when populating additional storage bays during initial build-out or field upgrades on an existing system.

The SATA interface supports standard 2.5-inch SATA HDDs and SSDs, making it a straightforward fit for workloads where NVMe density is not required and cost-effective SATA storage satisfies the capacity or IOPS target. For NVR-adjacent server deployments running surveillance storage workloads on HPE ProLiant infrastructure, SATA drives in high-bay configurations often represent the most economical path to large sequential write capacity.

Key Features

• 8SFF SATA Bay Configuration: Eight Small Form Factor bays in a single cage module — allows dense 2.5-inch drive population without requiring a chassis swap or platform change on the DL560 Gen11.
• BOX3 Cage Position: Targets a specific internal chassis position on the DL560 Gen11; verify your current cage population and HPE QuickSpecs for the DL560 Gen11 to confirm slot availability before ordering.
• SATA Interface: Compatible with standard SATA HDDs and SSDs — a practical choice when NVMe bandwidth is not the constraint and per-TB cost matters more than peak random IOPS.
• Platform-Specific Design: Engineered for the HPE ProLiant DL560 Gen11; not interchangeable with prior-generation DL560 or other ProLiant families without HPE verification.

Integration & Compatibility

This cage is purpose-built for the HPE ProLiant DL560 Gen11. Consult HPE QuickSpecs for the DL560 Gen11 to confirm supported drive types, backplane firmware requirements, and maximum SATA drive counts per storage configuration. For mixed SATA/NVMe deployments, HPE offers separate NVMe backplane options within the same server family — this cage (P59141-B21, also searched as P59141 B21) addresses the SATA-only cage position.

Frequently Asked Questions

Q: What server platform is the P59141-B21 designed for?

A: The P59141-B21 is designed for the HPE ProLiant DL560 Gen11 server. It is not confirmed compatible with prior DL560 generations or other ProLiant models without HPE verification.

Q: What drive interface does the P59141-B21 support?

A: The P59141-B21 uses a SATA interface, supporting standard 2.5-inch SATA HDDs and SSDs in an 8SFF configuration.

Q: What does BOX3 mean for the P59141-B21?

A: BOX3 refers to the internal cage position within the DL560 Gen11 chassis. Verify your chassis configuration using HPE QuickSpecs before ordering to confirm this cage position is unpopulated or replaceable.

Q: Can I use NVMe drives with the P59141-B21?

A: No. The P59141-B21 is a SATA cage; it does not support NVMe drives. HPE offers separate NVMe backplane options for the DL560 Gen11 for NVMe workloads.

Jerry Tildsen

The P59141-B21 is a platform-specific SATA drive cage for the HPE ProLiant DL560 Gen11 — the detail that matters most here is the BOX3 position designation, which tells you exactly where in the chassis this cage mounts. If your DL560 Gen11 build already has BOX1 and BOX2 populated, this is the logical next cage; if BOX3 is already filled, you have the wrong part number.

Technical Highlights:

• 8SFF SATA Bays: Eight 2.5-inch SATA slots in a single cage module — gives you a clean, dense storage expansion path on the DL560 Gen11 without requiring a platform change.
• SATA Interface: SATA is the right call when sequential write throughput and cost-per-TB matter more than NVMe latency — common in surveillance archival, backup targets, and capacity-tier storage roles.
• BOX3 Position Specificity: HPE ProLiant cage assemblies are chassis-position-coded; ordering the wrong BOX number means the backplane connector won't align. Always cross-reference the DL560 Gen11 QuickSpecs cage map before procurement.

Deployment Considerations:

• Confirm DL560 Gen11 chassis variant and current cage population via HPE QuickSpecs before ordering — cage positions and supported configurations vary by base chassis SKU.
• SATA-only cage: if the workload requires NVMe (low-latency video analytics, real-time indexing), this cage will not serve that need — size the storage tier correctly before specifying.

Best fit for a DL560 Gen11 deployed as a high-capacity SATA storage node — surveillance video retention, backup repository, or capacity-tier in a tiered storage architecture where sequential write density is the design constraint.
