Huawei Tecal CH221 IO Expansion Compute Node

The CH221 provides superior scalability and an outstanding memory capacity. Featuring Intel® Xeon® E5-2600 series processors (up to 135 W) and support for up to 24 DIMM slots, 2 internal hard disks, and 2 standard PCI x16 full-height full-length cards, the CH221 is suitable for high-performance computing applications that require graphics processing and application performance acceleration, such as oil exploration, animation rendering, scientific computing, and seismic processing.

Product Features

Large memory and outstanding expandability

  • 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).
  • Provides 4 PCIe x8 full-height half-length slots for installing 4 GPUs or PCIe SSDs, providing the best possible PCIe expansion capability on a single compute node.

(Note: card quantity is determined by card's physical size and the signal bandwidth.)

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.
