creating high-availability power solutions for the ProLiant ML570 server abstract Providing redundant power is imperative for maintaining high availability of servers. Therefore, the ProLiant ML570 server was designed to support hot-pluggable N+1 redundant power supplies. The way those power supplies are configured, however, is equally important for maintaining server availability.

creating high-availability power solutions for the ProLiant ML570 server With the configuration illustrated in figure 1, an outage from power grid A (with the two power supplies connected) would leave only one available power supply—not enough to support a maximum configuration of the server. In this worst-case scenario, the server would not only lose redundancy, but it might also lose availability.

creating high-availability power solutions for the ProLiant ML570 server solution for full redundancy Full redundancy for the ProLiant ML570 server can be achieved in an environment with two power grids by combining one dual-input PDU and two single-input PDUs (figure 3). In this configuration, each of the three power supplies is connected to a different PDU, and only one of them is connected to the dual-input PDU.

creating high-availability power solutions for the ProLiant ML570 server conclusion HP offers a wide range of power protection products for computer equipment ranging from individual workstations to servers to distributed enterprises. HP PDUs offer unparalleled power protection and distribution for rack-mounted servers and server options. Equipped with two inputs and a built-in AC transfer switch, the dual-input PDU is an excellent solution to provide fault resilience for mission critical environments.
