Adding a new server

Adding a new server into the server pool is done automatically through a process called “registration” (or enrollment). This process has two stages:

Stage 1: Automatic BMC (IPMI) configuration using DHCP

To automatically configure the management interface of a server follow the following procedure:

  1. Plug the server to the power interface (do not power on)
  2. The server will appear in the user interface in the registering state.
  3. If the default BMC/IPMI username and password combination for the type of server (for example: root/calvin for Dell servers)
  4. If the default configuration doesn’t work the server will wait in Registering state, with the flag server_ipmi_credentials_need_update set to true until the correct username and password is configured manually by the admin by using the server_update_ipmi_credentials function.
  5. The process should automatically continue. If it doesn’t the process can be retried manually by using the AFC interface and clicking on the Retry button.

Stage 2: Automatic server registering using auto-discovery

To perform an automatic discovery of components, configuration, network connections etc, the procedure is as follows:

Note: Admins can also skip directly to this stage by manually enabling PXE on all network interfaces via the BMC or the server’s BIOS, using an external KVM device or physical access to the server.

  1. Power on the server
  2. The server will go through the registration process automatically
  3. The server will shutdown automatically
  4. The server will be in the “Unavailable state” which means that the server has been successfully registered.
  5. Change the server class to big_data
  6. Change the server type to the required server type such as M8.32v1. For the very first server of a new configuration. The server type will need to be created using the “Create new server type” button to create a new server type from the current server’s configuration.
  7. Change the status to Available from the overview tab.

Auto-RAID

The system will automatically create a RAID array on supported systems at registration time. Consult the HCL for details on which servers are supported and under which conditions. Some additional licenses might be required in order for this feature to be available.

The RAID configuration depends on the size and number of drives.

For each group of identically sized drives (added to the same RAID controller) for the following count of identical drives:

  • 1 device -> RAID 0
  • 2 devices -> RAID 1
  • even number of devices -> RAID 10
  • odd number of devices -> RAID 5
