Dihuni OptiReady Tyan B8026T70AE24HR-7551-512-1 Low Latency Storage Server Configured/Tested with AMD EPYC 7551 32C CPU 512GB 24x450GB NVMe SSD 2GbE

Description

Featuring New AMD EPYC™ 7000 Series Processors

Tyan’s new AMD servers are engineered to unleash the full performance and rich feature sets on the new AMD EPYC™ 7000 Series processor family with more cores, more memory, more I/O, and more security. AMD EPYC processors are based on the 14nm “Zen” x86 core architecture with 32 cores and 64 threads, featuring 8 memory channels and up to16 DIMMs per socket. The new powerful processor allows Tyan to offer the optimal balance of computing, memory and I/O for the customers. By adopting the latest AMD EPYC processor technology, Tyan brings high memory channel bandwidth and PCI Express high speed I/O connectivity features to enterprises and data centers. With servers built on EPYC technology, cloud environments can drive greater scale and performance, virtualized data centers can further increase consolidation ratios while delivering better performing virtual machines and Big Data, and analytics environments can collect and analyze larger data sets much faster. High performance applications in research labs can solve complex problem sets in a significantly accelerated manner. EPYC, with all the critical compute, memory, I/O, and security resources brought together in the SoC with the right ratios, delivers industry-leading performance and enables lower TCO. With the flexibility to choose from 8 to 32 cores, EPYC enables you to deploy the right hardware platforms to meet your workload needs from virtualized infrastructure to large-scale big-data and analytics platforms and legacy line-of-business applications. For exact sever specifications, please see highlights below and also refer to detailed technical specifications.

Tyan’s TN70A-B8026 offers outstanding computational power for a single-socket server, with support for 8, 16, 24, or 32-Core processors with up to 64 threads. The memory capacity of the server is also incredibly high for a single socket server, able to support up to 2TB of RAM with every processor in the AMD EPYC SKU stack.

24 Hot-Swap NVMe Drive Bays

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 range. In comparison, high 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.

The TN70A-B8026 is designed to offer the most robust support for direct attached NVMe storage of any storage server ever made. The AMD EPYC architecture allows Tyan to supply 96 PCIe lanes for a total of 24 direct-attached NVMe bays without the need for any PCI switches or port multiplication.
