One of the most important tasks for every data center and computing cluster administrator is to manage and monitor the existing infrastructure. Often you need a lot of utilities, hardware, and software in order to do this. With HP Advanced Power Manager, you can simplify and hp_apmconsolidate the management and monitoring processes into one device and location.

 

/ What HP APM can do

By creating HP APM, HP wanted to create a tool for power management in their high-performance systems. However, they added many interesting features during the development that made this tool much more versatile than originally expected.

 

Key features of HP Advanced Power Manager:

– Consolidation of all iLO ports of servers

– Capability to remotely disable and enable devices, servers

– Monitoring of power, temperature at the PDU level, enclosure, and server

– Dynamic Power Capping

– Connecting the devices to the serial console (e.g. Top of the rack switch)

– UPS management

 

HP APM is used in HPC computing clusters, server farms for Big Data, Cloud Computing, etc.

For this purpose, HP has a suitable product lines including:

– HP SL6500 Scalable System

– HP Apollo 8000 System

– HP Apollo 6000 System

– HP Apollo 4000 System

– HP Apollo 2000 System

 

HP APM supports all these solutions, enabling to manage and monitor them.

 

/ Example of use

In December 2014, our company finished the installation of a computing cluster with more than 1300 XL230a Gen9 servers based on HP Apollo 6000 platform. Of course, HP Advanced Power Manager was included in the whole solution for configuring the cluster, and now it is used as a management and monitoring tool.

POWER MONITORING

 

Example:

Show power:

APMGV02> show power
  1       8       1       68    n/a      363   (DC watts)
   1       8       2    (empty)
   1       8       3       66    n/a      368   (DC watts)
   1       8       4    (empty)
   1       8       5       65    n/a      354   (DC watts)
   1       8       6    (empty)
   1       8       7       67    n/a      355   (DC watts)
   1       8       8    (empty)
   1       8       9       68    n/a      361   (DC watts)
   1       8      10    (empty)
   1       8      11       66    n/a      357   (DC watts)
   1       8      12    (empty)
   1       8      13       68    n/a      356   (DC watts)
   1       8      14    (empty)
   1       8      15       68    n/a      363   (DC watts)
   1       8      16    (empty)
   1       8      17       67    n/a      352   (DC watts)
   1       8      18    (empty)
   1       8      19       69    n/a      353   (DC watts)
   1       8      20    (empty)
   1       8    Fans       30                   (DC watts)
   1       8                                     706 (Chassis total - DC watts)
   1       8                                     706 (Chassis total - AC watts)

Pictured above is a summary of Apollo A6K enclosure power supply plugged into the port 8 of the APM equipped with 10 XL230a servers. Apollo 6000 enclosure can accommodate 20 XL220a servers in 5U, and because we have installed XL230a servers, we can see that we have 10 slots occupied.

A summary of power for the whole rack:

Total servers = 48
Total chassis = 5
Total fan wattage    =  152 (DC watts)
Total system wattage = 3445 (DC watts)
Total system wattage = 3445 (AC watts)

 

As you can see, we have 48 servers installed in 5 HP A6k enclosures, and looking at the current draw, they are currently “bored”.

REMOTE MACHINE SHUTDOWN

Sometimes it happens that we have to physically reboot the entire machine. Or we just want to switch it off. With HP APM, we can do it remotely

Example:

APMGV02> set power off 1 7 1
Dist. Module 1, port 7, server 1 was powered off
Show power 1 7 1 (offline) 1 7 2 (empty) 1 7 3 68 n/a 162 (DC watts)

 

As you can see, the show power command confirms that the server which had been “bored” has been completely shut down:

Other commonly used functions include:

Set power – power off or on the server

connect port – connection of connected devices to serial ports (Top of the rack switches in this case)

set ups – UPS connection and management

set syslog – redirection of logs to the external syslogd server

 

/ Conclusion

HP APM is a very versatile tool for monitoring and control of servers installed in our Data Center. Its capabilities will be especially appreciated by those who manage large server infrastructure, such as computing clusters, Big Data, Cloud Computing, etc. In conjunction with the new capabilities of iLO4, such as iLO Federation and HP One View, administrators now get consolidated, easy to configure platform for the management of their Data Center.

HP APM is already prepared for the expansion using add-ons, such as monitoring of environmental conditions in the Data Center, which makes it even more versatile.
