* SKU compatibility will depend on the maximum CPU TDP supported for each system, please refer to each product’s specification page for further information

Advanced features built into the silicon include:

Intel QAT: Speed up data compression and cryptography with integrated Intel QuickAssist Technology (QAT).
Intel AVX-512: Intel Advanced Vector Extension 512 instruction set architecture enables workload-optimized performance and throughput increases for advanced analytics, high performance computing (HPC) applications, and data compression.
Intel VROC: Intel Xeon Scalable Processors come with built-in support for Intel VROC (Virtual RAID on CPU). And GIGABYTE Intel Xeon Scalable NVMe SKU servers all ship with an Intel VROC module as standard.
Intel Omni-Path: Selected GIGABYTE servers support CPU SKUs with integrated Intel Omni-Path Fabric connection

Intel Optane Persistent Memory Ready

GIGABYTE’s second generation Intel Xeon Scalable family servers come ready to support Intel Optane™ Persistent Memory, a revolutionary new product that re-defines traditional memory & storage architectures by enabling a large persistent memory tier between DRAM and SSDs, that’s higher capacity than DRAM and faster than SSDs, enabling the user to bring more data closer to the CPU for faster time for insight.

Optane Persistent Memory Modules (“PMem”) integrate seamlessly into existing DDR4 DIMM slots, and use Intel’s 3D Xpoint memory technology, which unlike DRAM retains data after power is removed. The modules will be available in capacities up to 512GB – a massive increase compared to the current maximum 128GB of industry-leading DDR4 memory sticks – and can be addressed by the OS or application either as memory (Memory Mode) or storage (Application Direct Mode).

Note: the maximum number of Intel^® Optane™ PMem that can be installed per system and the DIMM slot positions that can be used for PMem will vary according to each server model due to thermal considerations. Please refer to each product’s specification page for further instructions.

Intel^® VROC Enabled

This server product is enabled for Intel VROC (Virtual RAID on CPU) to enable software RAID on connected Intel NVMe SSDs.

Dense Add-On Slot Design

GIGABYTE brings you the most comprehensive add-on slot options available: Low Profile/ OCP/ Full Height Half Length/ Full Height Full Length

3 x Low Profile & 2 x OCP in 1U

3 x Full Height Full Length & 5 x Full Height Half Length & 2 x OCP in 2U

6 x Full Height Half Length & 2 x Low Profile & 2 x 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 carefully selected to guarantee a stable operating environment and allow the processors and the memory to deliver their maximum performance. GIGABYTE’s server motherboards are built with long lasting components for a high degree of reliability and durability.

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
Supplying multiple connector options and tools where appropriate

Efficient, Reliable Power Supply

GIGABYTE SERVER Xeon Scalable servers are designed to guarantee high conversion efficiency regardless of load. Redundant 80 Plus ‘Titanium’ or ‘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.

Intelligent Power Management Features

Cold Redundancy

To take advantage of the fact that a PSU will run at greater power efficiency with a higher loading, GIGABYTE has introduced a power management feature called Cold Redundancy for servers with dual PSU. When the total system loading falls lower than 40%, the system will automatically place one PSU into standby mode, enabling the other PSU to take over the greater load. This can enable total system power efficiency savings of up to 10%.

System Power Efficiency

SCMP (Smart Crises Management / Protection)

SCMP is a GIGABYTE patented feature that will automatically force the system’s CPU to enter ULFM (ultra-low frequency mode for minimum power consumption) when the BMC is alerted to a PSU fault or error (such as power loss, power surge, overheating or a fan problem). This feature will prevent shutdown in systems with less than 1 + 1 PSU redundancy when one PSU is lost. In a 2U 4 Node server, only two nodes will be switched to low power mode, while two remaining nodes can continue normal operation. When the fault is resolved or the PSU is replaced, the system will automatically return to normal power mode.

GIGABYTE Server Management (GSM)

GIGABYTE Server Management (GSM) is GIGABYTE’s proprietary multiple server remote management software platform, available as a free download from each GIGABYTE server product page. GSM is compatible with either IPMI or Redfish connection interfaces, and comprises the following sub-programs:

GSM Server
A software program with an easy to use browser-based GUI to enable global remote monitoring and management of multiple GIGABYTE servers via each server node’s BMC.
GSM CLI (GBT Utility)
A command-line interface program to enable global remote monitoring and management of multiple GIGABYTE servers via each server node’s BMC.
GSM Agent
A software program installed locally on each GIGABYTE server node that retrieves additional node information (CPU/Mem/HDD/PCI/…) from the OS and passes it to the BMC. This information can then be utilized by GSM Server or GSM CLI.
GSM Mobile
A remote server management mobile APP, available for both Android and iOS.
GSM Plugin
A plugin that allows the user to manage and monitor GIGABYTE server nodes within VMware’s vCenter.

Intuitive & Informative User Interface

Starting from the GSM Server dashboard, the user can clearly understand the status of each node in the IT environment, including:

Node connection status (system is online/offline)
Node hardware sensor status (to detect hardware anomalies). Sensors measure voltage, fan speed and temperature
Node usage rate status (allowing you to timely allocate more resources when they are needed), including:
- Power consumption
- Disk/RAID usage information
- Memory usage rate
- CPU usage rate
- Network card / PCI information

The user can also perform various management functions, including:

Node remote access
- Power on / off / reset
- Launch iKVM
- Reboot BMC / BMC Account Configuration
Network Configuration
- IPv4/IPv6 setting
Alert Management
- SNMP trap setting
- Platform events filters
- Forwarding alerts by email
BMC / BIOS / CPLD Update
Power Consumption Limit Setting
Group Management
- Create groups of nodes for BMC / BIOS update or manage power consumption settings
