  • IBM Powers Up Software Development Lab With Rooftop Solar Array

    November 7, 2011 Timothy Prickett Morgan

    IBM has a Power Systems and System z software lab in Bangalore, India, appropriately enough called the India Software Lab. While there’s plenty of good IT talent in India and the Indian government likes for IBM to invest in the local economy to get the local business, Bangalore does have its problems. And a big one is that its electrical grid and power supply is not up to snuff.

    This can wreak havoc on a software lab that needs to keep Power and mainframe iron up and running to do software development and testing. IBM installed a fleet of backup diesel generators to tied it over when the power goes down, but Bangalore is a sunny place and one of the physicists in the lab started monkeying around with creating an array of solar cells to juice up the data center.

    IBM saw that it could be done, and funded the development of a 6,000 square foot array of solar panels that is capable of delivering 480-volt power directly into the data center and to keep the 50 kilowatts of computer equipment powered up for about 330 days a year for an average of five hours a day when Bangalore has trouble getting electricity to all of its customers. Presumably, IBM could install batteries to store juice and make the array larger and power the data center 24×7 if it has enough roof capacity.

    The 480-volt power coming off the solar array hooks directly into the server racks, which have been modified to support DC power as machines used in the telecommunications business have been for years. The racks also include water jackets to remove heat, and the solar array power these, too, as well as the air conditioning units that dump the heat outside. Eliminating this AC-to-DC conversion and using 480-volt power to the rack is much more efficient than all of the stepping down and transforming that typically goes on in data centers.

    All the cool data centers are doing it–pun intended.

    IBM is going to package up what the lab techs have created and sell it to other companies in remote areas or emerging markets that want to do something other than pay for diesel and smell the smoke when things go wrong in the power grid.

    Unit Test Automation: Secure Application Quality on IBM i

    Unit testing is arguably the most effective element of your testing strategy, driving the quality of your application as it is being developed.  Yet how can unit testing benefit legacy applications on IBM i – and especially those containing ‘monolithic’ sections of code?

    In this Webinar we will demonstrate how specialized unit test automation can safeguard application quality and generate reusable test assets for both modular and monolithic code.

    You will learn how to automate the IBM i unit testing process within a standard DevOps stack., including RDi, JUnit and Jenkins.

    Using ARCAD iUnit, you’ll see:

    • Automated test creation for modules, programs and service programs
    • Code coverage results
    • Mock capability – simulates key components like data, files programs
    • Test execution history
    • Version control with Git

    Watch Now and secure the quality of your IBM i application.
