Cirrascale GX4 Rackmount Server

The ultimate rackmount platform designed to peer up to 5 PCIe Gen 3 x16 compatible devices on a single root complex, including the NVIDIA® Tesla® P40 GPU Accelerator, powered by NVIDIA Pascal™ architecture, which is driving the AI revolution and enabling HPC breakthroughs, so you get only the best for your accelerated applications.

Product Features and Benefits

  • Supports dual Intel® Xeon® Processors E5-2600 v3/v4 family.
  • New low power, high speed DDR4 memory technology providing increased bandwidth and power efficiency while enabling higher overall memory bandwidth.
  • Supports the Cirrascale SR3615 PCIe switch riser enabling the peering of up to five PCIe devices on a single root complex.
  • A perfect solution for highly parallel applications like those used for deep learning, machine learning, and molecular dynamics such as Caffe, Torch 7, Theano, TensorFlow, and AMBER

Cirrascale GX4 Rackmount Server Overview

The new Cirrascale GX4 rackmount server series supports the recently released Intel® Xeon® processor E5-2600 v3/v4 product families and up to five PCIe Gen 3.0 devices enabling multi-device peering on a single PCIe root complex. This makes the GX4 a perfect solution for highly parallel applications and libraries like those used for deep learning, machine learning, and molecular dynamics such as Tensorflow, Caffe, Torch 7, Theano, and AMBER.

The Cirrascale GX4 implements the new low power, high speed DDR4 memory technology providing increased bandwidth and power efficiency while enabling higher overall memory bandwidth with lower density DIMMs. Additionally, the new systems provide improved performance of various high performance computing, professional imaging and feature detection applications and include next-gen networking improvements, new virtualization and security features. Overall, the Cirrascale GX4 is perfectly aligned for various scientific, analytics, and engineering applications worldwide, including those for deep learning, machine learning, and molecular dynamics.

Our SR3615 PCIe switch riser allows multiple PCIe devices to communicate as if they are all on the same bus... because they are. Gone are the days of needing a bounce-buffer in host memory, or leaving GPU DMA engines unused because they couldn't address other devices in the system. This reduces intercard latency while helping to maintain a consistent performance level between GPUs and other devices. Additionally, with a single address space and simultaneous inter-card communication at full PCIe x16 Gen3 speeds, software can spend more time doing work than thinking about when to schedule data copies.

With these new products, Cirrascale is facilitating data center transformation by providing scalable PCIe device performance. Customers deploying next generation scale-out infrastructure will benefit from the combination of Intel's latest processor platforms and Cirrascale's PCIe switch riser peering technology.

With the consistent advances in technology, Cirrascale engineering and development teams are constantly testing and deploying the latest technical specifications being offered by our technology partners. We make every effort to provide the below specifications error-free and up-to-date.
