Product Overview Intel® Xeon® Scalable Processors: Extend Your Scale
Introducing GIGABYTE’s new generation of motherboards and systems built around Intel’s Skylake Purley architecture - ‘Intel Xeon Scalable’. This new product family provides a wealth of new options in scalability - across compute, network and storage - to deliver solutions for a range of applications.

GIGABYTE’s system design and engineering expertise applied to this Intel Xeon Scalable series enables it to meet the increasingly diverse requirements of the industry, from entry-level HPC to large scale clusters.

Intel’s Xeon Scalable platform brings improved features and functionality at both the host and fabric levels. These enable performance improvements - both natively on chip and for future extensibility through compute, network and storage peripherals.

Xeon Scalable CPU Key Features:
• 28 Compute Cores.
• 6 Memory Channels.
• 48 PCIe Lanes.
• Intel Optane™ Support.
• Intel Omni-Path Ready.

CPU Highlights:
• Memory Optimization: Memory speeds of up to 2666MHz, with up to 12 DIMMs per socket.
• Storage: Built-in support for VROC & Intel Optane ready.
• Networking: Intel Omni-Path ready.

Increased Memory Performance
• The CPU architecture allows for up to 6 memory channels per socket and a bandwidth of up to 2666MHz.
• The architecture is future-ready with the potential to support Apache Pass DIMM.
• Memory capacity benefits with up to available 12 DIMMs per socket, which represents a 50% generation-on-generation increase.

Innovative Storage, Security and Networking

• Innovative storage options through Intel Optane™ low-latency, non-volatile design.
• These systems ship as standard with a Virtual Raid-On-CPU (VROC*) module to enable software raid on connected SSDs. * VROC is available by default on NVMe SKU.
• Support for SATA-DOM is available to allow for standalone boot and diagnostics direct through SATA connections on the board.

Integrated QAT for improved compression and security with software. On the hardware side, extra encryption on-board is enabled by TPMs available from GIGABYTE.

Improved networking through Omni-Path interconnect fabric as a CPU-integrated or standalone device.

Dense Add-On Slot Design Options
• 3x Low Profile & 2x OCP in 1U.
• 3x Full Height Full Length & 5x Full Height Half Length & 2x OCP in 2U.
• 6x Full Height Half Length & 2x Low Profile & 2x OCP in 2U.

Optimized for High TDP
GIGABYTE systems are thermally designed with the highest rated CPU SKUs in mind so that top performance is enabled which ever Xeon Scalable CPU you choose.

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. With some of the longest service lifetimes in the industry, our server motherboards are built with ultra-long lasting components to attain the highest reliability levels.

Ease of Deployment and Management
GIGABYTE continues to be responsive to market needs and to create 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
*A full toolkit is included with SKUs designed for 2.5” HDDs.

Efficient, Reliable Power Supply
GIGABYTE’s Xeon Scalable servers are designed to guarantee high conversion efficiency regardless of load. Redundant 80 Plus ‘Platinum’ PSUs, combined with GIGABYTE’s precision engineering, translates to super-efficient power usage which maximizes the system’s power:performance ratio and reduces OPEX for the 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.


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 (IMPI 2.0) or multiple boards simultaneously (CMD).

Custom Fan Speed Control (FSC)
GIGABYTE’s Dynamic Fan Policy is yet another feature designed to bring ease-of-use to administrators. With this function, individual servers can be orchestrated through both the BIOS and GIGABYTE’s proprietary software to maintain the optimal profile for current usage.

• Silent.
• Performance mode.
• Full load.
• Idle mode.
