PSU Working Mode
The X6000 V6 server supports the following PSU working modes:
●
●
Issue 08 (2023-12-12)
PSU Rated Power
and Server Rated
Power
Server < 2 PSUs
2 PSUs ≤ Server < 3
PSUs
3 PSUs ≤ Server
NO TE
After modifying the configuration or adding optional components, you need to recalculate the
total power of the server to check whether the current PSUs meet the requirements of the new
system.
Active/Standby mode:
– 1+1 active/standby mode: This mode is supported when the X6000 V6
server is configured with two PSUs and the real-time power of the server is
less than the rated power of a single PSU. In this mode, the active PSU
bears the system load, and the standby PSU works in the hot standby state.
– 2+2 active/standby mode: This mode is supported when the X6000 V6
server is configured with four PSUs and the real-time power of the server is
less than the total rated power of two PSUs. In this mode, two active PSUs
bear the system load, and the two standby PSUs work in hot standby state.
NO TE
After a PSU enters the hot standby state, the output current decreases and the power
indicator is steady green, which is the same as the normal state. You can query the PSU
status by running the ipmcget -d psuinfo command on the iBMC CLI. For details, see
the FusionServer X6000 Server iBMC User
In active/standby mode:
– If the real-time power of the server exceeds the total rated power of active
PSUs, the standby PSUs are woken up and the system enters the load
balancing mode.
– If any PSU is removed or the input is lost, the standby PSU is woken up and
enters the normal output state to ensure that the entire system is not
powered off.
Load balancing mode: In this mode, each PSU evenly bears the system load,
and their output power is similar.
