Octoputer 4U 10-GPU Server with Single Root Complex for GPUDirect – EOL

High-performance 10-GPU Server with all GPUs on a Single Root Complex

Note: NVIDIA announced an End of Sale Program for NVIDIA Tesla V100 GPUs in Summer 2021. We may still be able to source you these GPUs with long lead times. However, unless you are expanding an existing Tesla V100 deployment, we recommend selecting an NVIDIA A100 or A30 GPU based system such as Octoputer 4U 8/10 GPU Server

Microway’s 10-GPU Octoputer provides the highest number of GPUs within a single server and enables full connectivity between the GPUs. This design is ideal for applications which support GPU peering (using technologies such as GPUDirect® RDMA, P2P Peer-to-Peer, and Pascal Unified Memory). It supports up to ten double-width NVIDIA® GPUs in a 4U footprint (along with connectivity for high-speed networking, flash, or storage). Large amounts of traditional or high-speed storage can also be built into the server.

Each Octoputer arrives fully integrated with the operating system of your choice, along with the CUDA® toolkit installed and integrated. Additional libraries, tools, and software applications are available for an additional fee. All systems pass rigorous stress tests for over 48 hours prior to shipment.

Need more compute power? Microway provides turn-key Octoputer clusters including an InfiniBand interconnect and full GPU-Direct RDMA capability.

Configured for scaling with GPU-Direct RDMA

As shown in the diagram below, the single root complex allows for exceptional performance within the server and across a cluster of InfiniBand-connected systems. Utilizing GPU-Direct RDMA, any GPU in the cluster may directly access the data of any other GPU (remote memory access).

Configured for density with 10 GPUs per server

For projects which require many GPUs per system, the Octoputer may be configured with ten GPUs on a single PCI-Express root complex. As shown in the diagram below, one additional PCI-Express card may also be added (although this card is not on the same PCI-Express root complex).
