Huawei Tecal CH121 Compute Node

The CH121 combines dense computing capabilities with an ultra-large memory capacity. Optimized for computing-intensive enterprise service applications, virtualization, cloud computing, and high-performance computing, the CH121 employs Intel® Xeon® E5-2600 series processors (up to 135 W) and supports up to 24 DIMM slots, 2 internal hard disks, and 1 standard PCI x8 full-height half-length card.

Product Features

High density for massive computing capabilities

  • Supports the full series of Intel® Xeon® E5-2600 series quad-core, six-core, and eight-core processors to deliver up to 2*eight-core 2.9 GHz of computing power.
  • Provides 24 DIMMs at 1.5 times the usual height. These apply mainstream granules and double the memory capacity to up to 768 GB DDR3 (providing the highest cost-efficiency for large-memory applications).
  • Supports 2 x 2.5" SAS/SATA HDDs or SSDs.

Minimum energy for maximum efficiency

  • Adopts the dynamic energy saving and power capping technologies to optimally manage and control power consumption with power remarkably reduced in lowload operating.
  • Applies carrier-class design, manufacturing processes, and components to ensure high quality.

Intelligent platform for strong management

  • Reduces O&M costs by supporting remote deployment and fault location technologies such as SOL, KVM over IP, virtual DVD-ROM drive, WebUI and IPMI 2.0-compliant.
  • Provides efficient and secure power consumption analysis and control capabilities.
  • Complies with Intel® NM 2.0.
  • Provides a sub-3s power capping response on each compute node to optimize power consumption control.
  • Supports an intelligent and secure power-off mode for compute nodes.
  • Supports the black box function to facilitate quick fault location and service recovery.
