AMD EPYC™ 4004 for 24x7 Business Growth and Manageability

AMD EPYC™ 4004 Series Processors are a welcome addition to the 4th Gen AMD EPYC™ processor family, lowering the threshold for businesses and hosting services that have been wanting to move to a platform with a server OS and other enterprise features, yet at an optimal price point in GIGABYTE solutions. SMB and hosting services rely on server-grade reliability so they can continue running 24x7. At the same time, they need to have a higher degree of manageability. On top of validating, GIGABYTE provides GIGABYTE Management Console (GMC) for system management and GIGABYTE Server Management (GSM) software for monitoring multiple servers.

The Rising AM5 Platform

AMD AM5 Socket is versatile as it can support the consumer platform yet is able to step into the field of enterprise-level applications, and GIGABYTE has motherboards, workstations, and servers to support it. Taking advantage of its low cost per core and high core count options, the first processor on this platform, the AMD Ryzen™ 7000 Series, has proven its value in the enterprise server market. Its successor, the AMD EPYC™ 4004 Series, now further expands capabilities by including even more enterprise features. These “Zen 4” architecture processors can easily handle compute-heavy workloads yet are versatile enough for users to find an optimal choice for applications where performance, productivity, and efficiency matter.

Support for Server OS

GIGABYTE has validated platforms for compatibility with Windows Server, Ubuntu, and RHEL for greater manageability and security.

GIGABYTE R123-C00 (rev. AA01) Server Barebone

Ease of Management

GIGABYTE servers come with GIGABYTE Management Console for IPMI management. And with a server OS, greater management and control is possible.

GIGABYTE R123-C00 (rev. AA01) Server Barebone

Continuous Operation

Systems have RAS features for continuous uptime and availability as users require and expect stable performance around the clock.

Power Efficiency

Automatic Fan Speed Control

GIGABYTE servers are enabled with Automatic Fan Speed Control to achieve the best cooling and power efficiency. Individual fan speeds will be automatically adjusted according to temperature sensors strategically placed in the servers.

High Availability

Smart Ride Through (SmaRT)

To prevent server downtime and data loss as a result of loss of AC power, GIGABYTE implements SmaRT in all our server platforms. When such an event occurs, the system will throttle while maintaining availability and reducing power load. Capacitors within the power supply can supply power for 10-20ms, which is enough time to transition to a backup power source for continued operation.

Hardware Security

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.

Value-added Management

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

GIGABYTE Management Console

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:

  • Support for standard IPMI specifications that allows users to integrate services into a single platform through an open interface
  • Automatic event recording, which can record system behavior 30 seconds before an event occurs, making it easier to determine subsequent actions
  • Integrate SAS/SATA/NVMe devices and RAID controller firmware into GIGABYTE Management Console to monitor and control Broadcom® MegaRAID adapters

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 can be downloaded from GIGABYTE website and complies with IPMI and Redfish standards. GSM includes a complete range of system management functions that includes the following utilities:

  • GSM Server: A software program that provides real-time, remote control using a graphical user interface through an administrator’s 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.

The GIGABYTE R123-C00-AA01 is a 1U server barebones system for businesses and IT teams building a compact general-purpose server, with support for one AMD EPYC 4005/4004 or Ryzen 9000/7000 processor, four DDR5 UDIMMs, and four hot-swap SATA drives.

Recommended For

  • Small businesses and branch offices that need a rack-mounted server for everyday business services, such as file sharing, application hosting, or office infrastructure, and want remote management through the BMC.
  • Dedicated hosting and small-scale service providers deploying single-socket servers for web, SaaS, or other hosted workloads where rack density and power-conscious operation matter more than large core counts or extensive memory bandwidth.
  • IT teams building a compact, remotely managed rack server for a small virtualization or development lab, provided their plans fit a single CPU, four DDR5 UDIMM slots, and four SATA hot-swap drives.
  • Rack operators who need a short-depth 1U chassis for a space-constrained rack and can work within its four-drive SATA layout and single-socket design.
