Higher Performance and Scalability

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 datacenters.

Key Features

AMD EPYC 14nm CPU

● The AMD EPYC processor offers the highest possible performance from a single CPU socket, including:

● Up to 32 CPU cores and 64 threads
● Support for up to 2TB total RAM per socket on all CPU models
● 128 PCIe lanes

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:

● (8) PCIe x8 SFF-8611 Oculink connectors for NVMe
● PCIe Gen 3.0 x24 Riser Card Slot
● PCIe Gen 3.0 x16 Riser Card Slot
● PCIe Gen 3.0 x16 OCP LAN Mezzanine
● PCIe Gen 3.0 x2 NVMe M.2 ports for OS drives

High Expandability

The S8026 motherboard offers maximum expandability within a standard 12” x 13” SSI EEB form factor. This offers outstanding expansion capabilities in standard 1U server enclosures. A commodity 1U server chassis can support three PCIe x16 slots:

● (1) PCIe x16 OCP LAN Mezzanine (Supporting network speeds up to 100Gb/s)
● (2) PCIe x16 FH/HL cards (In Left and Right 1U riser cards)

Things get more interesting in a 2U chassis as the motherboard features a pair of PCIe x24 slots.Has a pair of available 2U riser cards with a MUX that support either x16/x0/x8 or x8/x8/x8 support, allowing each card to support up to one x16 slot and a x8 slot, or up to three x8 depending on configuration.

Outstanding SATA Performance

Each of the SATA ports on the AMD EPYC platform are derived from a PCIe x1 link. Unlike competing architectures which impose a performance bottleneck on the SATA controller, every SATA port on the AMD EPYC die get full SATA 6G throughput. This means that every single SATA port is fully capable of 550MB/s+ simultaneously. Early performance testing has shown total aggregate SATA performance in excess of 8GB/s across the board's 18 SATA ports.

Up to 18 SATA Ports

Some of the EPYC I/O ports can be remapped to support either PCIe or SATA ports. The s8026's BIOS supports I/O remapping on a pair of Oculink connectors, allowing the platform to support up to 18 SATA ports without an additional HBA.

180W CPU Support

AMD's top bin EPYC CPU supports up to 32 CPU cores and draws upwards of 180W. The s8026 VRM design can support the full range of AMD EPYC CPUs all the way up to their top bin 180W parts.
