Giga MS73-HB1 server MB
Accelerating Artificial Intelligence and Leading Efficiency

Engineering richer features in a revolutionary platform, Intel has made an incredible jump in processor performance in the business transformation journey. AI and deep learning performance will benefit from the built-in AI acceleration engines, while networking, storage, and analytics leverage other specialized accelerators in the 4th & 5th Gen Intel Xeon Scalable processors. Adding a host of new features to target a wide range of workloads, the new families of Intel Xeon processors will deliver even better CPU performance and performance per watt, and do so on a PCIe 5.0 platform with 2x the prior gen throughput to greatly speed up data movement to and from GPUs and storage. Intel also created the Intel Xeon CPU Max Series with High Bandwidth Memory (HBM) for improvements in memory bound HPC and AI workloads. For this new platform, GIGABYTE has products ready to get the most out of Intel Xeon CPU-based systems that support fast PCIe Gen5 accelerators and Gen5 NVMe drives.

Optional TPM 2.0 Module

For hardware-based authentication, the passwords, encryption keys, and digital certificates are stored in a TPM module to prevent unwanted users from gaining access to your data. GIGABYTE TPM modules come in either a Serial Peripheral Interface or Low Pin Count bus.

GIGABYTE Management Console
Value-added Management
GIGABYTE offers free-of-charge management applications via a specialized small processor built on the server.

For management and maintenance of a server or a small cluster, users can use the GIGABYTE Management Console, which is pre-installed on each server. Once the servers are running, IT staff can perform real-time health monitoring and management on each server through the browser-based graphical user interface. In addition, the GIGABYTE Management Console also provides:

GIGABYTE Management Console
  • Support for standard IPMI specifications that allows users to integrate services

  • Automatic event recording, which can record system behavior 30 seconds before an event occurs

  • ntegrate SAS/SATA/NVMe devices and RAID controller firmware into GIGABYTE Management Console

GIGABYTE Server Management (GSM)
GSM is a software suite that can manage clusters of servers simultaneously over the internet. GSM can be run on all GIGABYTE servers and has support for Windows and Linux.
  • GSM Server: A software program that provides real-time, remote control using a graphical user interface through an administrators computer or through a server in the cluster. The software allows ease of maintenance for large clusters of servers.
  • GSM CLI: A command-line interface for monitoring and managing remotely.
  • GSM Agent: A software program installed on each GIGABYTE server node that retrieves information from each system and devices through the OS, and this software integrates with GSM Server or GSM CLI.
  • GSM Mobile: A mobile app for both Android and iOS that provides admins with real-time system information.
  • GSM Plugin: An application program interface that allows users to use VMware vCenter for real-time monitoring and management of server clusters.
