Dell announced support for System Center 2012 R2 with their Management Packs

Thomas Jacob announced on his blog on Dell TechCenter global, that the Dell Management Packs now support Microsoft System Center 2012 R2.

Read more and download the Packs here.

You can now use the Dell OpenManage Integration Suite for Microsoft System Center with MicrosoftSystem Center 2012 R2 Operations Manager.  We have qualified all the Management Pack suites listed below on the latest version of OpsMgr and updated the documentation for R2 support.

• Dell Server Management Pack Suite ― Discover, inventory and monitor Dell PowerEdge servers (agent-based option with Windows/OpenManage Server Administrator and agent-free option using WSMAN for 12th Generation of Dell PowerEdge Servers), Chassis Management Controllers using SNMP &  iDRACs using SNMP.   Download: version 5.1 , Documentation

• Dell Client Management Pack –Discover, inventory and monitor Dell Client PCs running Windows andOpenManage Client Instrumentation (OMCI) ― Download: Dell Client Management Pack version 5.0 ,Documentation

• Dell Printer Management Pack –Discover, inventory and monitor Dell Printers using SNMP ― Download version 5.0Documentation

•Dell MD Storage Array Management Pack Suite –Discover, inventory and monitor Dell PowerVault MD Storage arrays ― Download version 5.0Documentation

• Dell EqualLogic Management Pack Suite–Inventory and monitor Dell EqualLogic storage arrays using SNMP―Download version 5.0Documentation

The latest releases of all the listed Dell Management Packs will work as-is for System Center 2012 R2 Operations Manager; the only exception is that the Chassis Modular Server Correlation feature of the Server MP Suite is not supported on R2 (110032 in the online Release Notes).

High Efficiency Cooling in Data Centers PUE about 1,05 – 1,10

A few weeks ago I had the chance to visit a high effiency cooling cell here in Berlin.

Together with Norman Beherzig, who wrote this blog, I want to share with you what I have learned.

If you have more questions, do not hasitate to reach out to me or Norman.

A cooling concept for modular indirect free cooling will be tested in the test data center of dc-ce in the technical University of Berlin

The cooling concept developed by dc-ce RZ-Planung, whose centerpiece is the AirBlock MIFC, allows achieving a high efficiency cooling in new and in existing buildings by optimally combining architecture and technology. This is possible in standard and in high efficiency data centers, which are consuming up to 40 kW per Rack.

The concept can be individually customized to the client needs. The AirBlock MIFC fits optimally in the spatial dimensions and it can also be delivered as Plug&Play solution. The AirBlock consist of reliable and highly available components such as an air-air heat exchanger, modern free controllable EC-Ventilators and other components, which are all exactly coordinated to avoid the pressure deficiency, and thus reducing the energy consumption. All these reasons along with the investment, energy and operation costs as well as the flexibility of the AirBlock MIFC make of it one the most efficient systems available on the market.

During the cooling of data centers most of the energy consumption comes from the mechanical production of cooling and the overcoming of pressure deficiency. Therefore, a high efficiency cooling would be one operating with the lowest pressure deficiency and having most of the time the compressor-based cooling off.

The solution is found in the most important component of the AirBlock MIFC which is a cross flow heat exchanger. It can operate longer than traditional cooling solutions in free cooling mode in temperatures from 10°C up to 12°C. This operation condition is supported by the free controllable EC-Ventilators, which by means of an intelligent control make it possible to always run the AirBlock MIFC exactly with the required air volume.


Increasing the Efficiency

The AirBlock MIFC offers a considerable efficiency increase in different areas:

 »» Full power operation in free cooling under appropriate temperatures of the data centers supply air (this value is free to be chosen by the Client) which oscillates in the range of 25°C down to 19°-22°C.

»» 85 % – 90 % free cooling per year according to the location

»» In case of having a partial load of 25% and with an outdoor temperature of around 20°C, only 1% of the IT-Load is required for supplying the cooling. This represents a very good optimization of the partial load behavior of the system.

»» In average only 5 % – 10 % of the IT-Load are required to provide cooling per year. Other modern cooling concepts achieve 20 % – 30 % in average per year while old systems have performances even over 50% of the IT-Load.

Please visit the test data center at the Technical University Berlin. Mr. Norman Beherzig is available for you to arrange your visit at the test data center  – n.beherzig@dc-ce.dewww.dc-ce.de.
