Power Management
Shared power in modular systems take advantage of the power pool by distributing power without the waste seen in
dedicated rack-mount servers and switchgear. The MX7000’s advanced power budget Inventory allows it to provide
priority to powering infrastructure while guaranteeing computing resources can be used.
The Management Module and each server’s iDRAC management controller negotiates its required power, whether that
be for simple power-on, AC recovery, or Wake-On-Lan. This inventory considers CPU, memory, storage, and other
server I/O to provide additional margin should any power shortage occur.
Budgeting is transparent to the system administrator. The MX7000 automatically protects against using more power
than is available by limiting which components can be powered on, as well as by dynamically limiting server power.
The MX7000 management module and the servers’ iDRAC modules work in concert to constantly monitor power
conditions in the chassis. In the event of a power shortage, they will instantaneously limit power to servers, decreasing
performance, but keeping the chassis online. Once the power shortage is corrected, servers will be allowed to return to
their full performance.
Power Supply Fault Detection
The PowerEdge MX7000 logs failures of PSUs. Notifications will be sent per the configuration in the OpenManage
Enterprise Modular web interface. The PSU utilizes four LEDs to help with issue identification: 3 on the front the PSU,
one on the back:
