Home Networking Servers & Storage HPE 874849-B21 XL190r Gen10 16NVMe FlexibleLOM Riser Kit

HPE 874849-B21 XL190r Gen10 16NVMe FlexibleLOM Riser Kit

Brand:
HPE

HPE 874849-B21 is the XL190r Gen10 16NVMe FlexibleLOM Riser Kit, a specialized secondary riser cage assembly for HPE ProLiant XL190r Gen10 configurations using 16 NVMe drives. It combines FlexibleLOM support with PCIe expansion and dedicated NVMe cabling, making it a configuration-focused accessory for high-density storage and accelerator deployments. HPE identifies this SKU specifically for the Apollo r2800 Gen10 chassis with 16 NVMe.

OVERVIEW

  • HPE 874849-B21 is the XL190r Gen10 16NVMe FlexibleLOM Riser Kit, designed for high-density NVMe and FlexibleLOM configurations. Compatibility: ProLiant XL190r Gen10 in the Apollo r2800 Gen10 chassis with 16 NVMe. Model comparison: 874847-B21 is the standard XL190r FlexibleLOM riser; 874849-B21 adds the documented 16-NVMe support.

USE CASES

  • 16-NVMe high-density storage deployments - Provides the required riser architecture for supported 16-NVMe configurations.
  • Apollo r2800 Gen10 systems - Designed for the documented 16-NVMe Apollo r2800 Gen10 chassis configuration.
  • FlexibleLOM networking deployments - Provides a FlexibleLOM interface alongside the NVMe-oriented riser architecture.
  • High-performance storage servers - Supports configurations where dense NVMe storage and PCIe connectivity are required.
  • GPU and accelerator configurations - Provides the secondary riser architecture used with supported accelerator-card configurations.
  • Enterprise data-center infrastructure - Helps system integrators build standardized high-density HPE Gen10 server configurations.
  • NVMe server expansion projects - Provides a platform-specific riser when moving to the documented 16-NVMe architecture.
  • HPE server replacement and spares - Supplies an exact HPE option number for configuration restoration and lifecycle management.

KEY FEATURES

  • 16NVMe FlexibleLOM riser design - Combines high-density NVMe support with FlexibleLOM connectivity in a purpose-built XL190r configuration.
  • 16-NVMe support - Enables the documented high-density NVMe architecture for the Apollo r2800 Gen10 chassis.
  • FlexibleLOM support - Provides a dedicated FlexibleLOM interface for supported network adapters.
  • PCIe 3.0 expansion - Provides PCIe 3.0 x16 interfaces for supported accelerator and expansion configurations.
  • Four dedicated NVMe cable connections - Provides the documented Slimline SAS cable interfaces required for the 16-NVMe riser architecture.
  • Secondary riser cage assembly - Adds expansion capability through the XL190r Gen10 secondary riser position.
  • Supports 1:1 CPU-to-GPU configuration - HPE documents this riser for configurations using a 1:1 CPU:GPU ratio.
  • HPE-specific option 874849-B21 - Simplifies procurement, BOM preparation, system integration, and replacement planning.
