A reader of my blog asked me what seemed like a simple enough question:
Whatever happened to Lotus Approach? I loved that personal db. (thoughit's been awhile...)
Of course, researching an answer, I encountered some interesting new information. Interestingly, everyone tries to "read between the lines" and tries to determine what solution is best.
From a colleague from Lotus:
You can still get [Lotus Approach] as part of Smartsuite.
I am familiar with Cloudscape, and I evaluated it as a potential database for IBM TotalStorage Productivity Center, when I was the lead architect defining the version 1 release. It runs entirely on Java, which is both a plus and minus. Plus in that it runs anywhere Java runs, but a minus in that it is not optimized for high performance or large scalability. Because of this, we decided instead on using the full commercial DB2 database instead for Productivity Center.
Not to be undone, my colleagues over at DB2 offered a different alternative, [DB2 Express-C], which runs on a variety of Windows, Linux-x86, and Linux on POWER platforms. It is "free" as in beer, not free as in speech, which means you can download and use it today at no charge, and even ship products with it included, but you are not allowed to modify and distribute altered versions of it, as you can with "free as in speech" open source code, as in the case of Derby above (see [Apache License 2.0"] for details).
(If you have no idea what I am talking about in my distinction between "free speech" and "free beer", see Simon Phipps' artiAs I see it, DB2 Express-C has two key advantages. First, if you like the free version, you can purchase a "support contract" for those that need extra hand-holding, or are using this as part of a commercial business venture. Second,for those who do prefer vendor lock-in, it is easyto upgrade Express-C to the full IBM DB2 database product, so if you are developing a product intended for use with DB2, you can develop it first with DB2 Express-C, and migrate up to full DB2 commercial version when you are ready.
This is perhaps more information than you probably expected for such a simple question. Meanwhile, I am stilltrying to figure out MySQL as part of my [OLPC volunteer project].Read More]
Many people have asked me if there was any logic with the IBM naming convention of IBM Systems branded servers. Here's your quick and easy cheat sheet:
From a storage perspective, we often joked that the "i" stood for "island", as most System i machines used internal disk, or attached externally to only a fewselected models of disk from IBM and EMC that had special support for i5/OS using a special, non-standard 520-byte disk block size. This meant only our popular IBM System Storage DS6000 and DS8000 series disk systems were available. This block size requirement only applies to disk. For tape, i5/OS supports both IBM TS1120 and LTO tape systems. For the most part,System i machines stood separate from the mainframe, and the rest of the Linux, UNIX and Windows distributed serverson the data center floor.
Often, when I am talking to customers, they ask when will product xyz be supported on System z or System i?I explained that IBM's strategy is not to make all storage devices connect via ESCON/FICON or support non-standard block sizes, but rather to get the servers to use standard 512-byte block size, Fibre Channel and other standard protocols.(The old adage applies: If you can't get Mohamed to move to the mountain, get the mountain to move to Mohamed).
On the System z mainframe, we are 60 percent there, allowing three of the five operating systems (z/VM, z/VSE and Linux) to access FCP-based disk and tape devices. (Four out of six if you include [OpenSolaris for the mainframe])But what about System i? As the characters on the popular television show [LOST] would say: It's time to get off the island!
Last week, IBM announced the new [i5/OS V6R1 operating system] with features that will greatly improve the use of external storage on this platform. Check this out:
Now that's exciting!

While many are just becoming familiar with the end-user interfaces of Web 2.0, from blogs and wikis to FaceBook and FlickR, fewer may be familiar with the "information infrastructure" of servers and storagebehind the scenes.
Last year, I bought an XO laptop under the One Laptop Per Child [OLPC] foundation's Give-1-Get-1 program and posted my impressions on this blog. One in particular, my post[Printingon XO laptop with CUPS and LPR] showed how to print from the XO laptop over to a network-attached printer.This caught the attention of the OLPC development team, who asked me tohelp them with another project as a volunteer. Before accepting, I had to learn what skills they were really looking for, especially since I do notconsider myself an expert in neither printing nor networking.
(Unlike a regular 9-to-5 job where most people just try to look busy for eight hours a day, doingvolunteer work means being ready to ["roll up your sleeves"] and actuallyaccomplish something. This applies to any kind of volunteer work, from hammering nails for [Habitat for Humanity] to sorting cans at the [Community Food Bank].Best Buy uses the phrase "Results Oriented Work Environment" [ROWE] to describetheir latest program, modeled in part after the mobile workforce policies of Web2.0-enlightened companiesIBM and Sun, but that is perhaps a topic for another blog post!)
Apparently, to support a school full of students with XO laptops, it would be nice to have a few serversthat provide support to manage the class lesson plans, make reading materials and other content available,and keep track of results. What they need is an "information infrastructure"! They decided on two specific servers:
In keeping with OLPC philosophy to use free and open source software[FOSS], both servers are based on the [LAMP] platform. LAMP is an acronym for thecombined software bundle of Linux, Apache, MySQL and a Programming language like PHP. The "XS" team working onthe school server wanted me to build a LAMP server and install Moodle to help test the configuration, determinewhat other software is required, and perhaps develop a backup/recovery scenario. Basically, they needed someone with Linux skills to put some hardware and software together.
(I am no stranger to Linux. Back in the 1990s, I was part of the Linux for S/390 team, led the effort to createthe infamous "compatible disk layout" (CDL) that allows z/OS to access ESCON and FICON-attached Linux volumes,took my LPI certification exam, and led a team to validate FCP drivers for our disk and tape storage systems. For an IBMer to volunteer foran Open Source community project, you have to take an "open source" class and get management approval to reviewfor any possible "conflicts of interest". I got this all taken care of, and accepted to help the XS team.)
Building a test environment is similar to baking a cake. You have a recipe, utensils, and ingredients. Here'sa bit of description of each of the ingredients:
As for utensils, you only need a few utilities
As for a recipe, the Moodle website spells out some unique details and parameters. For the base LAMP platform,I chose to follow the book [Fedora 7 Unleashed] that has specific chapters on setting up SSH, Apache, MySQL, PHP, Squid and so on. The resu Here were the sequence of events: I got all of this done last Saturday, start to finish. Now the fun begins. We are going to run throughsome tests, document the procedures, and try to get a system up and running in a remote school in Nepal. Fornow, I have only one XO laptop to simulate what the student sees, and one laptop that can represent eithera teacher's Windows-based laptop, or run QEMU and emulate a second XO laptop.For tuning, I might go through the procedures mentioned on IBM Developerworks "Tuning LAMP"[Part 1, Part 2,Part 3]. For those in the server or storage industry that need to understand Web 2.0 information infrastructure better,building a LAMP server like this can be quite helpful.

An astute reader, Andrea, asked me the following:
Are you covering the business impact of the internet failure across Asia, the Middle East and North Africa? The outage has brought business in those regions to a standstill. This disaster shines a direct spotlight on the vulnerability of technology and serves as a reminder of the ever increasing importance of protecting business critical information.
When I first heard of this outage, I am thinking, so a few million people don't have access to FaceBook and YouTube, what's the big deal? We in the U.S.A. are in the middle of a [Hollywood writer's strike] and don't have fresh new television sitcoms to watch! Yahoo News relays the typical government's response:[Egypt asks to stop film, MP3 downloads during Internet outage], presumably so that real business can take priority over what little bandwidth is still operational. Fellow IBM blogger "Turbo" Todd Watson pokes fun at this, in his post[Could Someone Please Get King Tutankhamun On The Phone?].Like us suffering here in America, perhaps our brothers and sisters in Egypt and India may getre-acquainted with the joys of reading books.
However, the [Internet Traffic Report-Asia] shows how this impacted various locations including: Shanghai, Mumbai, Tokyo, Tehran, and Singapore. In some cases, you have big delays in IP traffic, in other cases, complete packet loss, depending on where each country lies on the["axis of evil"].This is not something just affecting a few isolated areas, the impact is indeed worldwide. This would be a goodtime to talk about how computer signals are actually sent.
Wikipedia has a good article on [Submarine Communications Cable],including a discussion on how repairs are made when they get damaged or broken.It is important to remember that lost connectivity doesn't mean lost data, just lack of access to the data. Thedata is still there, you just can't get to it right now. For some businesses, that could be disruptive to actualoperations. In other cases, it means that backups or disk mirroring is suspended, so that you only have yourlocal copies of data until connectivity is resumed.
ABC News had this report:[Conspiracy theories emerge after internet cables cut]. Of course, Al Qaeda practiced their bombing skills in their own backyard, from embassies inAfrica to the [USS Cole], before taking it toNew York and Washington. Here's an excerpt:
When two cables in the Mediterranean were severed last week, it was put down to a mishap with a stray anchor.
It gets weirder. In his blog Rough Type, Nick Carr's[Who Cut the Cables?] reportsnow a fourth cable has been cut, in a different location than the other two cable locations. If the people cuttingthe cables are looking to see how much impact this would have, they will probably be disappointed. Nick Carrrelates how resilient the whole infrastructure turned out to be:
Though India initially lost as much as half of its Internet capacity on Wednesday, traffic was quickly rerouted and by the weekend the country was reported to have regained 90% of its usual capacity. The outage also reveals that the effects of such outages are anything but neutral; they vary widely depending on the size and resources of the user.
IBM does have a large outsourcing, help-desk and R&D presence in these areas. Al Jazeera reports[India wrestles with internet outage]:
Outsourcing firms, such as Infosys and Wipro, and US companies with significant back-office and research and development operations in India, such as IBM and Intel, said they were still trying to asses how their operations had been impacted, if at all.
Whether it is man-made or natural disaster, every business should have a business continuity plan. If you don't have one, or haven't evaluated it in a while, perhaps now is a good time to do that. IBM can help.Read More]
I got the following comment on my earlier post [A Recap of Storage Industry Acquisitions], Reuben wrote:
According to Gartner data (from 2005!), host-based storage accounts for 34 percent of the overall market for external storage, with the remaining 66 percent going to "fabric-attached" (network) storage, expect this share to grow from 66 percent to 77 percent by 2007.What is the current reality? SAN vs. NAS, FC vs iSCSI?
IBM subscribes to a lot of data from different analysts, they all have their methods for collecting this data, from taking surveys of customers to reviewing financial results of each vendor. While theymight not agree entirely, there are some common threads that lead one to believe they represent "reality". Hereare some numbers from an IDC December 2007 report:
Jon Toigo over at DrunkenData offers some additional data from ex-STKer:[Fred Moore Outlook on Storage 2008]. I met Fredat a conference. He had left STK back in 1998, and started his own company called Horison. NeitherJon nor Fred cite the sources of his statistics, but the following comment leads me to assume hehasn't been paying attention closely to the tape market:
With the demise of STK, who will be the leader in the tape industry?
