CMC for Chassis Management & Multi-Node Monitoring

The server features a Chassis Management Controller (CMC) for chassis-level management and node-level monitoring by connecting nodes internally via BMC chips integrated on each node. Resulting in only one mLAN connection required to perform monitoring of all four nodes*, and results in less Top-of-Rack (ToR) cabling and switch connections.

* IPMI only (no iKVM functionality)

Ring Topology Management

The server features the ability to create a "ring" connection for monitoring & management of all servers in a rack for greater cost savings and management efficiency.

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 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.
