If you're wondering what all the “Big Data” buzz is all about, you have to read IBM’s Big Data FlashBook. It's a great explanation about cost-effective solutions to the three Vs that are the characteristics of big data: volume, variety, and velocity.

AIX has more than the usual suite of performance monitoring tools. You'll find common Unix tools, such as fuser, ps, sar, tcpdump, and the like, as well as many AIX-unique utilities. Here is a rough guide to the tools you should keep near to hand when trouble requires shooting.

When exploiting the massive consolidation resources of IBM's newest Power 6 & 7 systems, the most common resource to run out of first is network capacity. Unlike CPU and memory capacity, which can scale by a factor of 100 or more, network capacity can only increase by a factor of 10, from 1G to 10G Ethernet. Given this upper boundary on a single Ethernet channel, it's critical that you tune your system—and your network—to make efficient use of this resource.

Mel Beckman, our senior technical director for Power IT Pro, will be delivering just one of many free sessions on Power System tips and technology next week during our
Power IT Pro Virtual Conference. We’re pretty excited about the event, mostly because we know it’s jam-packed with excellence. (And you can’t beat the price!) Of course, topics: IBM Senior Engineer Jim Mitchell will outline IBM’s Power Systems strategy and directions in the keynote, followed by a hands-on with AIX 7 session by Rob McNelly.

If you have a large number of files to write to a file system, you can cut down the time it takes by turning off file system logging. This no logging feature was introduced in AIX 6.1 for Enhanced Journaled File Systems (JFS2). It can give you a much-needed performance boost and can come in handy when you want to copy or restore thousands of files into a file system. You could use this, for example, when you are migrating data to new storage.

One of the cool things we get to do here at Power IT Pro is to extend our content -- it's not just articles -- out to everyone around the world. We do webcasts and events, and where they really shine is getting experts to condense the good stuff down into PowerPoint slides and then talk about it using natural language. Articles are great, don't get me wrong, but sometimes a more off-the-cuff explanation through the spoken word can help make something confusing surprisingly clear.

While we haven't extensively covered cloud computing yet at Power IT Pro, there are a handful of well-respected players offering AIX-focused professionals the ability to serve up Power Systems-based servers from the so-called clouds.
Connectria is one, and I know the company serves up a variety of AIX-focused configurations for several dozen customers, large and small. The latest company to invest in IBM Power Systems cloud offerings is
Logicalis, which is offering its new Enterprise Power Cloud service -- based on IBM Power 770-class systems capable of supporting multi-tenancy running AIX and i5/OS virtual servers.

IBM today announced record-breaking benchmark results for WebSphere middleware on a single server representing the highest performance in the information technology (IT) industry. IBM set new records for speed of operation in Java-based software on a Power 780 server and on Power 730 Express as validated by the independent SPEC, a non-profit corporation formed to establish, maintain and endorse a standardized set of relevant benchmarks.
