PSU Working Mode
The X6000 V6 server supports the following PSU working modes:
⚫
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.
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 Guide
.
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.
PSUs work in load balancing mode by default. To set the PSUs to work in active/standby
mode, log in to the iBMC WebUI, choose

to set the Work Mode to
Active/Standby
. Table 3-3 describes PSU working
modes based on the relationship between the real-time power of the server and that of PSUs
when different number of PSUs are configured.

You can change it to 1+1 active/standby
