Dual Socket Feature Set Traditionally, the only way to deploy a large number of PCIe devices has been to select a dual-socket motherboard even if the compute demands of the server was low. Tyan has targeted these applications with the AMD EPYC platform by supporting up to 124 PCIe lanes and 8 memory channels in a single-socket platform. Significant savings can be had both in CPU cost and power consumption by migrating workloads to a single socket AMD EPYC platform. 124 PCIe Lanes The s8026 motherboard was designed from the ground up to take full advantage of AMD's Single-Socket I/O capabilities. The board exposes 124 PCIe lanes across a variety of connectors:
16 NVMe Ports NVMe technology offers breakthrough performance for SSDs by attaching storage devices directly to the PCIe bus, freeing them from the SATA protocol that was originally designed for slower rotational media. This technology significantly reduces storage latency and increases transfer speeds. To put things into perspective, during the summer of 2017 the fastest SATA SSDs on the market were already saturating the SATA 6G bus with peak sequential transfer rates of 550MB/s read and 520 MB/s write. The bigger pipe and lower latency of the NVMe PCIe x4 link allows the fastest NVMe SSDs to reach sequential read rates of 3,500MB/s and read rates around 2,100MB/s. Non-sequential performance heavily favors NVMe devices as well, with typical SATA SSDs achieving 4K random read/write performance around the 100K IOPS mark. In comparison, performance NVMe devices routinely offer 4K random R/W numbers in the neighborhood of 350-450K+ IOPS. Previous motherboard designs were not well suited to NVMe deployment due to a lack of PCIe lanes. Each NVMe device requires a PCIe x4 link. Large numbers of these devices could not previously be deployed without expensive and bottleneck inducing switch chips or without quickly running out of I/O resources for other devices in the server. The AMD EPYC CPU is ideal for this storage technology, featuring support for 128 PCIe lanes from a single CPU socket. |
