Maximum throughput for superior application performance

NVLink provides a high-speed path between GPUs, allowing them to communicate peak data rates of 300 GB/s, a speed 10X faster than PCIe. Unlike PCIe, with NVLink a device has multiple paths to choose from, and rather than share a central hub to communicate, they instead use a mesh that enables the highest bandwidth data interchange between GPUs. This significantly speeds up applications and delivers greater raw compute performance than GPUs using PCIe. By increasing the total bandwidth between the GPU and other parts of the system, the data flow and total system throughput are improved to enhance the performance of the workload.

SATA vs M.2 NVMe

High Density SXM2 GPU solution

The system supports 8 Tesla SXM2 V100 GPUs installed on the GPU mainboard add-on module which is connected to the motherboard by a midplane. The GPU mainboard is connected through Nvidia’s Cube Mesh NVLINK architecture. Direct connection between all GPUs are single NVlink (25 GB/s). A direct connection from the GPUs to the network can be provided from the PCI-E PLX switch to the PCI-E3.0 x16 up front. Each PCI-E PLX switch is root to two SXM2 modules and one PCI-E3.0 x16 slot. A fast network (expansion) card installed on the riser card affords very high speeds. Data can go from GPU to the PLX to the NIC without going through the CPU. For the NIC, the system can support both FDR and EDR (in x16 slots).

GPUDirect RDMA (remote direct memory access) enables network devices to directly access GPU memory, bypassing CPU host memory altogether.

  • Accelerated communication with network and storage devices
  • Peer-to-Peer transfers and memory access between GPUs
  • Eliminate CPU bandwidth and latency bottlenecks using remote direct memory access (RDMA) transfers between GPUs and other PCI-E devices

System Health Monitoring

The system has an onboard Baseboard Management Controller (BMC) chip that supports system health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage becomes unstable, it will give a warning or send an error message to the IPMI WebGUI and IPMIView. Real time readings of these voltage levels are all displayed in IPMI.

Fan Status Monitor with Firmware Control

The system health monitor embedded in the BMC chip can check the RPM status of the cooling fans. The CPU and chassis fans are controlled via lPMI.

Environmental Temperature Control

System Health sensors in the BMC monitor the temperatures and voltage settings of onboard processors and the system in real time via the IPMI interface. Whenever the temperature of the CPU or the system exceeds a user-defined threshold, system/CPU cooling fans will be turned on to prevent the CPU or the system from overheating.

System Resource Alert

This feature is available when used with SuperDoctor 5. SuperDoctor 5 is used to notify the user of certain system events. For example, you can configure SuperDoctor 5 to provide you with warnings when the system temperature, CPU temperatures, voltages and fan speeds go beyond a predefined range3
