Lenovo Deal Done, Power Systems Takes Center Stage
October 6, 2014 Timothy Prickett Morgan
… Read moreWell, the deal is done, and IBM is completely and finally out of the X86 server business now that it has sold off the System x division to Lenovo Group. Or, to be more precise, has sold off the System x business in most of the major countries where IBM and Lenovo both had operations and could do the transfer and get the approval of regulators. Now, we find out exactly how committed Big Blue is to the Power Systems platform.
Ever since the homogenization of the server lines that started at the end of the 1990s when Sam

IBM Rolls Out The Big Power8 Iron
October 6, 2014 Timothy Prickett Morgan
… Read moreCustomers looking to boost the capacity of their existing enterprise-class Power Systems servers got some reprieve late last week when ahead of the Enterprise2014 conference in Las Vegas IBM did a surprise launch of the E870 and E880 servers. The machines are follow-ons to the existing Power 770+ and Power 780+ machines and borrow technologies from the Power 795 announced four years ago.
The resulting E870 and E880 systems are designed to take the modularity that has been inherent in the Power Systems line since the Power5 machines were announced a decade ago and merge it with the high-end NUMA

IBM Deals On V3700 Arrays, Preps Dedupe For FlashSystem
September 29, 2014 Timothy Prickett Morgan
… Read moreIf you are shopping for disk arrays for your IBM i systems, IBM has a deal for you on adjunct software functions for its Storwize V3700 storage. And the company is also making promises about adding some advanced functions to the FlashSystem flash-based arrays as well.
In announcement letter 314-098, IBM is offering software function upgrades for the V3700 at no charge. The deal is applied to the Storwize Turbo performance boost, which cranks up the I/O operations per second on the array by 50 percent and doubles the maximum throughput as measured in gigabytes per second for the

More Reader Feedback On Power8 Processing Power And What Matters
September 29, 2014 Timothy Prickett Morgan
… Read moreSorry for the delay in thanking you, but I have just returned from TEN weeks consulting in Singapore to rescue another AS/400 customer whose chief developer died as they were about to start a Singapore plant (12 time zones away). Plus continuing consulting when I would much rather be relaxing on my deck (the customer licensed RTPA, which is why I went to Singapore and continue consulting).
I worked 12 hours a day at the plant (24 by 7 operation) as the ONLY IT person, plus 2 hours a day traveling in a van from my $10,000 a month luxury

IBM Clarifies IBM i 6.1.1 And Support Withdrawal
September 29, 2014 Timothy Prickett Morgan
… Read moreThe IBM i 6.1.1 release of the midrange operating system that this newsletter is dedicated to was, like many prior releases of the OS/400 and its progeny, a stop-gap release to add support for Virtual I/O Server and was pretty thin as releases go. As we reported several weeks ago, IBM is set to withdraw IBM i 6.1 from marketing on December 9 and stop supporting it on September 30, 2015. But there was not perfect clarity on what would happen to its tweaked follow-on, IBM i 6.1.1.
As we previously reported, IBM withdrew IBM i 6.1 and

How IBM Stacks Up Entry Power8 Machines Against X86 Iron
September 29, 2014 Timothy Prickett Morgan
… Read moreWe are on the verge of an expanded Power8 system line from IBM and rival Intel has launched its next-generation “Haswell” Xeon E5-2600 v3 processors. But the performance specs that compare the Power8 iron to X86 and other alternatives in the midrange are only just starting to trickle out of Big Blue. So now is a good time to take a look and then brace ourselves for more comparisons in the coming months.
In past issues of The Four Hundred, I have showed how the scale-out variants of the raw Power8 processors rate in terms of raw Commercial Processing

Cisco’s UCS Mini Enters The Midrange Arena
September 29, 2014 Timothy Prickett Morgan
… Read moreOver the past five years, some remarkable changes have happened in the systems business. IBM‘s Power Systems business has dropped from around $5 billion down to around $3 billion and Cisco Systems has built a converged system business that has gone from zero to $3 billion. Cisco has gotten more than its fair share of the blade server market with green-field applications like private clouds and virtual desktop infrastructure (VDI), and now it is looking both low and high to expand its business further.
The fact that Cisco is trying to move from enterprise-class blade servers to minimalist machines

Admin Alert: What’s The Danger Zone For IBM i Disk Utilization?
September 24, 2014 Joe Hertvik
… Read moreWorking on IBM i and its predecessor machines for 30 years, I sometimes have to modify or redo advice that I’ve relied on for years. Case in point: how full does your disk space have to be before you put your IBM i partition in danger?
I had an experience this month that made me question my assumptions on when you should worry about and how you should set your disk utilization thresholds. Here’s what happened.
What Went Before
In the past, I’ve recommended setting your disk utilization thresholds so that the IBM OS issues this system operator message when

A Bevy Of BIFs: %ScanRpl (Scan And Replace)
September 24, 2014 Jon Paris
… Read moreThis gem of a BIF was introduced with the V7.1 release and so was not available some five years ago when I wrote my original Bevy series of tips. Now that more people have V7.1 in their shops, I decided it was time to revisit the series and add it to the collection. It is probably my all-time favorite BIF . . . at least so far.
Simply put, %ScanRpl will search a target string for a given character sequence and replace it with another. Not only that but it will then continue to search through the target string and

Testing The Ruby Waters
September 24, 2014 Aaron Bartell
… Read moreAs of October 2013 Ruby is supported on IBM i via PowerRuby. This is good news as Ruby has become a very popular programming language for producing web applications because of its simplicity, flexibility, and vast community. In this article we will be introducing you to tools that aid in learning Ruby on IBM i.
Often times the easiest way to learn a programming language is by starting small and playing with it. Ruby makes this very easy to do with its included Interactive Ruby Shell, or irb for short.
The irb environment is also called REPL (Read,
