Product Information
AMD EPYC™
The New x86 Option
AMD’s return to the CPU segment delivers a whole new value proposition to the x86 world. Built on GIGABYTE’s extensive design expertise across a range of chipset platforms, this AMD EPYC™ platform is already receiving acclaim for its high specification:
- Memory
- I/O
- Network connectivity
This platform is intended as an alternative for builders in the x86 space and packs a real punch in flexibility and expansion options.
Comprehensive I/O
Both single- and dual-socket CPUs come equipped with 128x PCIe lanes, providing extensive I/O options. This is a huge improvement in I/O vs. incumbent x86 offerings.
Increased I/O allows for flexibility in extending your storage, networking or compute to a level previously unattainable with standard server motherboards.
In addition, the integrated nature of the processor – designed as a system-on-chip (SoC) - means that there is no need for a separate PCH and less additional switches needed for expansion lanes.
Dense, High Speed Storage Support
Onboard U.2 + M.2
GIGABYTE AMD EPYC™ platforms are designed to support U.2 and M.2 storage devices. Both use the NVMe protocol, taking advantage of the fast bandwidth of PCIe Gen3 x 4 lanes to deliver up to 32 Gb/s data transfer speeds, over 4 times the performance of SATA 3, giving you more flexibility to integrate some of the most dense and fastest storage devices on the market into your system.
Data Security
TPM 2.0 Module
GIGABYTE’s EPYC™ platform is designed to support Trusted Platform Modules (TPM - discrete cryptographic on-board processors).
Carefully Selected Components
GIGABYTE’s passive components are meticulously selected to guarantee a super stable operating environment and allow the processors and the memory to deliver their maximum performance. GIGABYTE’s server motherboards are built with ultra long lasting components for the highest reliability attainable which allows us to offer some of the most durable servers in the industry.
Ease of Deployment and Management
GIGABYTE is always responsive to market needs and user-friendly solutions, including:
- Tool-less rail kit included as a default across all new server models
- In-house designed proprietary tool-less sleds for 3.5” HDDs to allow for easy swapping
- Supplying multiple connector options and tools where appropriate
Efficient, Reliable Power Supply
All of GIGABYTE’s new generation servers are guaranteed to offer a conversion efficiency of >90% regardless of load. This, combined with GIGABYTE’s precision design, translates to super efficient power usage which maximizes the system’s power:performance ratio and cuts OPEX for the end user.
GIGABYTE Server Management (GSM)
GIGABYTE’s proprietary software, ‘GIGABYTE Server Management’, is designed to provide an effortless user experience. This software can be downloaded as a ‘GSM Client’/ ‘GSM Agent’/ ‘GSM Server’ module – depending on user applications - all of which are IPMI and Redfish compliant. Through these protocols, users and administrators can manage and monitor their server groups easily and remotely through multiple concurrent sessions.
GIGABYTE BMC Interface
Easy BIOS Upgrade
GIGABYTE has developed this integrated function (requiring no additional software) that allows users to update the BIOS of motherboards through the BMC controller:
- No need to install core components such as CPUs, memory, drives and OS
- No need to power on the system (NB. PSU must be connected)
- Update individual (IPMI 2.0) or multiple boards simultaneously (Command Line)
Environmental Compliance
GIGABYTE maintains its commitment to green products, and adheres to the latest RoHS regulations (in effect July 2017).
