Well, it's Tuesday again, and that means more IBM announcements!
Today, IBM announced the enhanced IBM System Storage DS3200 disk system.It is in our DS3000 series, the DS3200 is SAS-attach, DS3300 is iSCSI-attach, and DS3400 is FC-attach. All of them support up to 48 drives, which can be a mix of SAS and SATA drives.
The DS3200 supports the following operating environments (see IBM's [Interop Matrix] for details):
- Microsoft Windows
- Linux (both Linux-x86 and Linux on POWER)
- Sun Solaris
- Novell NetWare
With today's announcements, the DS3200 can be used to boot from, as well as contain data. This is ideal to combine with IBM BladeCenter. With the IBM BladeCenter you can have 14 blades, either x86 or POWER based processors, attached to a DS3200 via SAS switch modules in the back of the chassis.
Let's take an example of how this can be used for a Scale-Out File Services[SoFS] deployment.
First, we start with servers. We can have either three [IBM System x3650] servers, but this would use up all six of the direct-attach ports. Instead, we'll choose the [BladeCenter H chassis], with three HS21 blades for SoFS, and that leaves us with eleven empty blade slots we could put in a management node, or other blades to run applications.
- SAS connectivity modules
The IBM BladeCenter [SAS Connectivity Module] allows the blade servers to connect to a DS3200. Two of them fit right in the back of the BladeCenter chassis, providing full redundancy without consuming additional rack space.
- DS3200 and EXP3000 expansion drawers
We'll have one DS3200 controller with twelve internal drives, and three expansion EXP3000 drawers with twelve drives each, for a total of 48 drives. Using 1TB SATA, this would be 48 TB raw capacity.
The end result? You get a 48TB NAS scalable storage solution, supporting up to 7500 concurrent CIFS and NFS users, with up to 700 MB/sec with large block transfers. By using BladeCenter, you can expand performance by adding more blades to the Chassis, or have some blades running SAP or Oracle RAC have direct read/write access to the SoFS data.
Just another example on how IBM can bring together all the components of a solution to provide customer value!

In my presentations in Australia and New Zealand, I mentioned that people were re-discovering the benefits of removable media. While floppy diskettes were convenient way of passing information from one person to another, they unfortunately did not have enough capacity. In today's world, you may need Gigabytes or Terabytes of re-writeable storage with a file system interface that can easily be passed from one person to another. In this post, I explore three options.
- Cirago CDD2000 Docking Station
The good folks over at [Cirago International Ltd.] sent me a cute little [CDD2000 docking station] for evalution.
(FCC Disclaimer: I work for IBM, and IBM has no business relationship with Cirago at the time of this writing. Cirago has not paid me to mention their product, but instead provided me a free loaner that I promised to return to them after my evaluation is completed. This post should not be considered an endorsement for Cirago's products. List prices for Cirago and IBM products were determined from publicly available sources for the United States, and may vary in different countries. The views expressed herein may not necessarily reflect the views and opinions of either IBM or Cirago.)
I took a few photos so you can see what exactly this device looks like. Basically, it is a plastic box that holds a single naked disk drive. It has four little rubber feet so that it does not slip on your desk surface.
The inside is quite simple. The power and SATA connections match those of either a standard 3.5 inch drive, or the smaller form factor (SFF) 2.5 inch drive. However, to my dismay, it does not handle EIDE drives which I have a ton of. After taking apart six different computer systems, I found only one had SATA drives for me to try this unit out with.
The unit comes with a USB cable and AC/DC power adapter. In my case, I found the USB 3.0 cable too short for my liking. My tower systems are under my desk, but I like keeping docking stations like this on the top of the desk, within easy reach, but that wasn't going to happen because the USB cable was not long enough.
Instead, I ended up putting it half-way in between, behind my desk, sitting on another spare system. Not ideal, but in theory there are USB-extension cables that probably could fix this.
Here it is with the drive inside. I had a 3.5 inch Western Digital [1600AAJS drive] 160 GB, SATA 3 Gbps, 8 MB Cache, 7200 RPM.
To compare the performance, I used a dual-core AMD [Athlon X2] system that I had built for my 2008 [One Laptop Per Child] project. To compare the performance, I ran with the drive externally in the Cirago docking station, then ran the same tests with the same drive internally on the native SATA controller. Although the Cirago documentation indicated that Windows was required, I used Ubuntu Linux 10.04 LTS just fine, using the flexible I/O [fio] benchmarking tool against an ext3 file system.
- Sequential Write - a common use for external disk drive is backup.
- Random read - randomly read files ranging from 5KB to 10MB in size.
- Random mixed - randomly read/write files (50/50 mix) ranging from 5KB to 10MB in size.
|Sequential Write||Throughput IOPS||1119||1044|
| ||Latency (msec)||0.866 ms||0.948 ms|
| ||Bandwidth (KB/s)||16900||14400|
|Random Read||Throughput (IOPS)||164||119|
| ||Latency (msec)||6.06 ms||8.36 ms|
| ||Bandwidth (KB/s)||658||477|
|Random Mixed (50/50)||Throughput (IOPS)||112||81|
| ||Latency (msec) read||8.78 ms||12.1 ms|
| ||Latency (msec) write||0.0983 ms||0.120 ms|
| ||Bandwidth (KB/s) read||557||328|
| ||Bandwidth (KB/s) write||556||337|
For sequential write, the Cirago performed well, only about 15 percent slower than native SATA. For random workloads, however, it was 30-40 percent slower. If you are wondering why I did not get USB 3.0 speeds, there are several factors involved here. First, with overheads, 5 Gbps USB 3.0 is expected to get only about 400 MB/sec. My SATA 2.0 controller maxes out at 375 MB/sec, and my USB 2.0 ports on my system are rated for 57 MB/sec, but with overheads will only get 20-25 MB/sec. Most spinning drives only get 75 to 110 MB/sec. Even solid-state drives top out at 250 MB/sec for sustained activity. Despite all that, my internal SATA drive only got 16 MB/sec, and externally with the Cirago 14 MB/sec in sustained write activity.
Here is the mess that is inside my system. The slot for drive 2 was blocked by cables, memory chips and the heat sink for my processor. It is possible to damage a system just trying to squeeze between these obstacles.
However, the point of this post is "removable media". Having to open up the case and insert the second drive and wire it up to the correct SATA port was a pain, and certainly a more difficult challenge than the average PC user wishes to tackle.
Price-wise, the Cirago lists for $49 USD, and the 160GB drive I used lists for $69, so the combination $118 is about what you would pay for a fully integrated external USB drive. However, if you had lots of loose drives, then this could be more convenient and start to save you some money.
- IBM RDX disk backup system
Another problem with the Cirago approach is that the disk drives are naked, with printed circuit board (PCB) exposed. When not in the docking station, where do you put your drive? Did you keep the [anti-static ESD bag] that it came in when you bought it? And once inside the bag, now what? Do you want to just stack it up in a pile with your other pieces of equipment?
To solve this, IBM offers the RDX backup system. These are fully compatible with other RDX sytems from Dell, HP, Imation, NEC, Quantum, and Tandberg Data. The concept is to have a docking station that takes removable, rugged plastic-coated disk-enclosed cartridges. The docking station can be part of the PC itself, similar to how CD/DVD drives are installed, or as a stand-alone USB 2.0 system, capable of processing data up to 25 MB/sec.
The idea is not new, about 10 years ago we had [Iomega "zip" drives] that offered disk-enclosed cartridges with capacities of 100, 250 and 750MB in size. Iomega had its fair share of problems with the zip drive, which were ranked in 2006 as the 15th worst technology product of all time, and were eventually were bought out by EMC two years later (as if EMC has not had enough failures on its own!)
The problem with zip drives was that they did not hold as much as CD or DVD media, and were more expensive. By comparison, IBM RDX cartridges come in 160GB to 750GB in size, at list prices starting at $127 USD.
- IBM LTO tape with Long-Term File System
Removable media is not just for backup. Disk cartridges, like the IBM RDX above, had the advantage of being random access, but most tape are accessed sequentially. IBM has solved this also, with the new IBM Long Term File System [LTFS], available for LTO-5 tape cartridges.
With LFTS, the LTO-5 tape cartridge now can act as a super-large USB memory stick for passing information from one person to the next. The LTO-5 cartridge can handle up to 3TB of compressed data at up to SAS speeds of 140 MB/sec. An LTO-5 tape cartridge lists for only $87 USD.
The LTO-5 drives, such as the IBM [TS2250 drive] can read LTO-3, LTO-4 and LTO-5cartridges, and can write LTO-4 and LTO-5 cartridges, in a manner that is fully compatible with LTO drives from HP or Quantum. LTO-3, LTO-4 and LTO-5 cartridges are available in WORM or rewriteable formats. LTO-4 and LTO-5 cartridges can be encrypted with 256-bit AES built-in encryption. With three drive manufacturers, and seven cartridge manufacturers, there is no threat of vendor lock-in with this approach.
These three options offer various trade-offs in price, performance, security and convenience. Not surprisingly, tape continues to be the cheapest option.

Since so many personal and corporate users are still on [Windows XP], Microsoft announced that it would provide [Extended Support until 2014]. A ComputerWorld article back in 2007 offered tips on [How to make Windows XP last for the next seven years]. From May 2009 to April 2014, all support is fee-based and non-security hotfixes are produced only for corporate customers.
If we have learned anything from last decade's Y2K crisis, is that we should not wait for the last minute to take action. Now is the time to start thinking about weaning ourselves off Windows XP. IBM has 400,000 employees, so this is not a trivial matter.
Already, IBM has taken some bold steps:
Last July, IBM announced that it was switching from Internet Explorer (IE6) to [Mozilla Firefox as its standard browser]. IBM has been contributing to this open source project for years, including support for open standards, and to make it [more accessible to handicapped employees with visual and motor impairments]. I use Firefox already on Windows, Mac and Linux, so there was no learning curve for me. Before this announcement, if some web-based application did not work on Firefox, our Helpdesk told us to switch back to Internet Explorer. Those days are over. Now, if a web-based application doesn't work on Firefox, we either stop using it, or it gets fixed.
IBM also announced the latest [IBM Lotus Symphony 3] software, which replaces Microsoft Office for Powerpoint, Excel and Word applications. Symphony also works across Mac, Windows and Linux. It is based on the OpenOffice open source project, and handles open-standard document formats (ODF). Support for Microsoft Office 2003 will also run out in the year 2014, so moving off proprietary formats to open standards makes sense.
I am not going to wait for IBM to decide how to proceed next, so I am starting my own migrations. In my case, I need to do it twice, on my IBM-provided laptop as well as my personal PC at home.
- IBM-provided laptop
Last summer, IBM sent me a new laptop, we get a new one every 3-4 years. It was pre-installed with Windows XP, but powerful enough to run a 64-bit operating system in the future. Here are my series of blog posts on that:
I decided to try out Red Hat Enterprise Linux 6.1 with its KVM-based Red Hat Enterprise Virtualization to run Windows XP as a guest OS. I will try to run as much as I can on native Linux, but will have Windows XP guest as a next option, and if that still doesn't work, reboot the system in native Windows XP mode.
Here's is how I have configured my laptop:
|/dev/sda1||35GB||NTFS||C:||Windows XP SP3 operating system and programs|
|/dev/sda2||15GB||ext4||/(root)||Ubuntu Desktop 10.10, SystemRescueCD, Clonezilla, Parted Magic|
|/dev/sda3||55GB||ext4||/(root)||RHEL 6.1 with KVM to run Windows XP as guest OS|
|/dev/sda6||130GB||NTFS||D:||My Documents, Lotus Notes and other data|
|/dev/sda7||70GB||NTFS||E:||Extras and Archives|
Basically, this is a multi-boot system. I use Ubuntu to hold all my Linux utilities, including [SystemRescueCD], [Clonezilla], and [Parted Magic]. The new [Grub2 loader] makes this easy.
Here is what my initial boot screen looks like:
So far, I am pleased that I can do nearly everything my job requires natively in Red Hat Linux, including accessing my Lotus Notes for email and databases, edit and present documents with Lotus Symphony, and so on. I have made RHEL 6.1 my default when I boot up. Setting up Windows XP under KVM was relatively simple, involving an 8-line shell script and 54-line XML file. Here is what I have encountered:
- We use a wonderful tool called "iSpring Pro" which merges Powerpoint slides with voice recordings for each page into a Shockwave Flash video. I have not yet found a Linux equivalent for this yet.
- To avoid having to duplicate files between systems, I use instead symbolic links. For example, my Lotus Notes local email repository sits on D: drive, but I can access it directly with a link from /home/tpearson/notes/data.
- While my native Ubuntu and RHEL Linux can access my C:, D: and E: drives in native NTFS file system format, the irony is that my Windows XP guest OS under KVM cannot. This means moving something from NTFS over to Ext4, just so that I can access it from the Windows XP guest application.
- For whatever reason, "Password Safe" did not run on the Windows XP guest. I launch it, but it takes forever to load and never brings up the GUI. Fortunately, there is a Linux version [MyPasswordSafe] that seems to work just fine to keep track of all my passwords.
- Personal home PC
My Windows XP system at home gave up the ghost last month, so I bought a new system with Windows 7 Professional, quad-core Intel processor and 6GB of memory. There are [various editions of Windows 7], but I chose Windows 7 Professional to support running Windows XP as a guest image.
Here's is how I have configured my personal computer:
|/dev/sda1||104MB||NTFS||C:||Windows 7 Loader|
|/dev/sda2||10GB||ext4||/(root)||Ubuntu Desktop 10.10, SystemRescueCD, Clonezilla, Parted Magic|
|/dev/sda6||60GB||NTFS||C:||Windows 7 OS and programs|
|/dev/sda7||230GB||NTFS||D:||My Documents, Lotus Notes and other data|
|/dev/sda8||250GB||NTFS||E:||Extras and Archives|
I actually found it more time-consuming to implement the "Virtual PC" feature of Windows 7 to get Windows XP mode working than KVM on Red Hat Linux. I am amazed how many of my Windows XP programs DO NOT RUN AT ALL natively on Windows 7. I now have native 64-bit versions of Lotus Notes and Symphony 3, which will do well enough for me for now.
I went ahead and put Red Hat Linux on my home system as well, but since I have Windows XP running as a guest under Windows 7, no need to duplicate KVM setup there. At least if I have problems with Windows 7, I can reboot in RHEL6 Linux at home and use that for Linux-native applications.
Hopefully, this will position me well in case IBM decides to either go with Windows 7 or Linux as the replacement OS for Windows XP.

Wrapping up this week's theme on the XO laptop, I decided to take on thechallenge of printing. I managed to print from my XO laptop to my laserjet printer.I checked the One Laptop Per Child [OLPC
] website,and found there is no built-in support for printers, but there have been several peopleasking how to print from the XO, so here are the steps I did to make it happen.
(Note: I did all of these steps successfully on my Qemu-emulated system first, and then performed them on my XO laptop)
- Step 1: Determine if you have an acceptable printer
The XO laptop can only connect to a printer via USB cable or over the network.Check your printer to see if it supports either of these two options. In my case, my printer is connected to my Linksys hub that offers Wi-Fi in my home.
The XO runs a modified version of Red Hat's Fedora 7, so we need to also determineif the printer is supported on Linux.Check the [Open Printing Database]for the level of support. This database has come up with the following ranking system.Printers are categorized according to how well they work under Linux and Unix. The ratings do not pertain to whether or not the printer will be auto-recognized or auto-configured, but merely to the highest level of functionality achieved.
- Perfectly - everything the printer can do is working also under Linux
- Mostly - work almost perfectly - funny enhanced resolution modes may be missing, or the color is a bit off, but nothing that would make the printouts not useful
- Partially - mostly don't work; you may be able to print only in black and white on a color printer, or the printouts look horrible
- Paperweight - These printers don't work at all. They may work in the future, but don't count on it
If your printer only supports a parallel cable connection, or does not have a high enough ranking above, go buy another printer. The [Linux Foundation] websiteoffers a list of suggested printers and tutorials.
In my case, I have a Brother HL5250-DN black-and-white laserjet printer connected over a network to Windows XP, OS X and my other Linux systems. It is rated as supporting Linux perfectly, so I decided to use this for my XO laptop.
- Step 2: Install Common UNIX Printing System (CUPS)
Technically, Linux is not UNIX, but for our purposes, close enough. Start the Terminalactivity, use "su" to change to root, and then use "yum" to install CUPS. Yum will automatically determine what other packages are needed, in this case paps and tmpwatch. Once installed, use "/usr/sbin/cupsd" to get the CUPS daemon started, and add this to the end ofrc.local so that it gets started every time you reboot.

[olpc@xo-10-CC-6F ~]$ subash-3.2# yum install cups...Total download size = 3.0 MIs this OK [y/N]? y
bash-3.2# /usr/sbin/cupsdbash-3.2# echo "/usr/sbin/cupsd" >> /etc/rc.d/rc.localbash-3.2# exit[olpc@xo-10-CC-6F ~]$
- Step 3: Install Opera or Firefox browser
To download the appropriate drivers, you may need a browser that can handle file downloads. I have triedto do this with the built-in Browse activity (aka Gecko) but encountered problems. I have both Opera and Firefox installed, but I will focus on Opera for this effort.I also installed the older126.96.36.199 version of the Flash player (worked better than the latest 188.8.131.52 version) and Java JRE.Follow the OLPC Wiki instructions for [Opera, Adobe Flash,and Sun Java] installation, thenverify with the following [Java and Flash] testers.
- Step 4: Download drivers and packages unique for your printer
In my case, I used Opera to get to the [Brother Linux Driver Homepage], and downloaded the RPM's for LPR and CUPS wrapper. These are the ones listed under "Drivers for Red Hat, Mandrake (Mandriva), SuSE". I saved these under "/home/olpc" directory.
[olpc@xo-10-CC-6F ~]$ subash-3.2# cd /home/olpcbash-3.2# rpm -vi brhl5250dnlpr-2.0.1-1.i386.rpmbash-3.2# rpm -vi cupswrapperHL5250DN-2.0.1-1.i386.rpmbash-3.2# exit[olpc@xo-10-CC-6F ~]$
- Step 5: Create a "root" password
By default, the root user has no password. However, you will need it to be something for later steps,so here is the process to create a root password. I set mine to "tony" which normallywould be considered too simple a password, but ignore those messages and continue.We will remove it in step 8 (below) to put things back to normal.
[olpc@xo-10-CC-6F ~]$ subash-3.2# passwdChanging password for user root.New UNIX password: tonyBAD PASSWORD: it is too shortRetype new UNIX password: tonypasswd: all authentication tokens updated successfullybash-3.2# exit[olpc@xo-10-CC-6F ~]$
- Step 6: Launch CUPS administration
Here I followed the instructions in Robert Spotswood's [Printing In Linux with CUPS] tutorial.Launch the Opera browser, and enter "http://localhost:631/admin" as the URL. The localhostrefers to the laptop itself, and 631 is the special port that CUPS listens to from browsers. You can alsouse 127.0.0.1 as a shortcut for "localhost", and can be used interchangeably.
In my case, it detected both of my networked printers, so I selected the HL5250DN, entered thelocation of my PPD file "/usr/share/cups/model/HL5250DN.ppd" that was created in Step 4. I set the URI to "lpd://192.168.0.75/binary_p1" per the instructions [Network Setting in CUPS based Linux system] in the Brother FAQ page. I chage the page size from "A4" to "Letter".I set this printer as the default printer. When it asks for userid and password, that is whereyou would enter "root" for the user, and "tony" or whatever you decided to set your root password to.
Select "Print a Test Page" to verify that everything is working.
- Step 7: Printing actual files
Sadly, I don't know Opera well enough to know how to print from there. So, I went over to my trustedFirefox browser. Select File->Page Setup to specify the settings, File->Print Preview tosee what it will look like, and then File->Print to send it to the printer.
To print the file "out.txt" that is in your /home/olpc directory, for example, enter"file:///home/olpc/out.txt" as the URL of the firefox browser. This will show the file,which you can then print to your printer. I had to specify 200% scaling otherwise the fontswere too small to read.
- Step 8: Remove the "root" password
If you want to remove the root password, here are the steps.
[olpc@xo-10-CC-6F ~]$ suPassword: tonybash-3.2# passwd -d rootRemoving password for user root.passwd: Successbash-3.2# exit[olpc@xo-10-CC-6F ~]$
Now the problem is that there is no way to print stuff from any of the Sugar activities. The best place toput in print support would be the Journal
activity. Along the bottom where the mounted USB keys arelocated could be an icon for a printer, and dragging a file down to the printer ojbect could cause it tobe send to the printer.
The alternative is to write some scripts invocable from the Terminal activity to determine what isin the journal, and send them to LPR with the appropriate parameters.
I did not have time to do either of these, but perhaps someone out there can take on that as a project.

My how time flies. This week marks my 24th anniversary working here at IBM. This would have escaped me completely, had I not gotten an email reminding me that it was time to get a new laptop. IBM manages these on a four-year depreciation schedule, and I received my current laptop back in June 2006, on my 20th anniversary.
When I first started at IBM, I was a developer on DFHSM for the MVS operating system, now called DFSMShsm on the z/OS operating system. We all had 3270 [dumb terminals], large cathode ray tubes affectionately known as "green screens", and all of our files were stored centrally on the mainframe. When Personal Computers (PC) were first deployed, I was assigned the job of deciding who got them when. We were getting 120 machines, in five batches of 24 systems each, spaced out over the next two years. I was assigned the job of recommending who should get a PC during the first batch, the second batch, and so on. I was concerned that everyone would want to be part of the first batch, so I put out a survey, asking questions on how familiar they were with personal computers, whether they owned one at home, were familiar with DOS or OS/2, and so on.
It was actually my last question that helped make the decision process easy:
How soon do you want a Personal Computer to replace your existing 3270 terminal?
- 1-60 days
- 61-120 days
- 121-180 days
- As late as possible
I had five options, and roughly 24 respondents checked each one, making my job extremely easy. Ironically, once the early adopters of the first batch discovered that these PC could be used for more than just 3270 terminal emulation, many of the others wanted theirs sooner.
Back then, IBM employees resented any form of change. Many took their new PC, configured it to be a full-screen 3270 emulation screen, and continued to work much as they had before. My mentor, Jerry Pence, would print out his mails, and file the printed emails into hanging file folders in his desk credenza. He did not trust saving them on the mainframe, so he was certainly not going to trust storing them on his new PC. One employee used his PC as a door stop, claiming he will continue to use his 3270 terminal until they take it away from him.
Moving forward to 2006, I was one of the first in my building to get a ThinkPad T60. It was so new that many of the accessories were not yet available. It had Windows XP on a single-core 32-bit processor, 1GB RAM, and a huge 80GB disk drive. The built-in 1GbE Ethernet went unused for a while, as we had 16 Mbps Token Ring network.
I was the marketing strategist for IBM System Storage back then, and needed all this excess power and capacity to handle all my graphic-intense applications, like GIMP and Second Life.
Over the past four years, I made a few slight improvements. I partitioned the hard drive to dual-boot between Windows and Linux, and created a separate partition for my data that could be accessed from either OS. I increased the memory to 2GB and replaced the disk with a drive holding 120GB capacity.
A few years ago, IBM surprised us by deciding to support Windows, Linux and Mac OS computers. But actually it made a lot of sense. IBM's world-renown global services manages the help-desk support of over 500 other companies in addition to the 400,000 employees within IBM, so they already had to know how to handle these other operating systems. Now we can choose whichever we feel makes us more productive. Happy employees are more productive, of course. IBM's vision is that almost everything you need to do would be supported on all three OS platforms:
- Lotus Notes
Access your email, calendar, to-do list and corporate databases via Lotus Notes on either Windows, Linux or Mac OS. Corporate databases store our confidential data centrally, so we don't have to have them on our local systems. We can make local replicas of specific databases for offline access, and these are encrypted on our local hard drive for added protection. Emails can link directly to specific entries in a database, so we don't have huge attachments slowing down email traffic. IBM also offers LotusLive, a public cloud offering for companies to get out of managing their own email Lotus Domino repositories.
- Lotus Symphony
Create presentations, documents and spreadsheets on either Windows, Linux or Mac OS. Lotus Symphony is based on open source OpenOffice and is compatible with Microsoft Office. This allows us to open and update directly in Microsoft's PPT, DOC and XLS formats.
- Firefox Browser
Many of the corporate applications have now been converted to be browser-accessible. The Firefox browser is available on Windows, Linux and Mac OS. This is a huge step forward, in my opinion, as we often had to download applications just to do the simplest things like submit our time-sheet or travel expense reimbursement. I manage my blog, Facebook and Twitter all from online web-based applications.
The irony here is that the world is switching back to thin clients, with data stored centrally. The popularity of Web 2.0 helped this along. People are using Google Docs or Microsoft OfficeOnline to eliminate having to store anything locally on their machines. This vision positions IBM employees well for emerging cloud-based offerings.
Sadly, we are not quite completely off Windows. Some of our Lotus Notes databases use Windows-only APIs to access our Siebel databases. I have encountered PowerPoint presentations and Excel spreadsheets that just don't render correctly in Lotus Symphony. And finally, some of our web-based applications work only in Internet Explorer! We use the outdated IE6 corporate-wide, which is enough reason to switch over to Firefox, Chrome or Opera browsers. I have to put special tags on my blog posts to suppress YouTube and other embedded objects that aren't supported on IE6.
So, this leaves me with two options: Get a Mac and run Windows on the side as a guest operating system, or get a ThinkPad to run Windows or Windows/Linux. I've opted for the latter, and put in my order for a ThinkPad 410 with a dual-core 64-bit i5 Intel processor, VT-capable to provide hardware-assistance for virtualization, 4GB of RAM, and a huge 320GB drive. It will come installed with Windows XP as one big C: drive, so it will be up to me to re-partition it into a Windows/Linux dual-boot and/or Windows and Linux running as guest OS machine.
(Full disclosure to make the FTC happy: This is not an endorsement for Microsoft or against Apple products. I have an Apple Mac Mini at home, as well as Windows and Linux machines. IBM and Apple have a business relationship, and IBM manufactures technology inside some of Apple's products. I own shares of Apple stock, I have friends and family that work for Microsoft that occasionally send me Microsoft-logo items, and I work for IBM.)
I have until the end of June to receive my new laptop, re-partition, re-install all my programs, reconfigure all my settings, and transfer over my data so that I can send my old ThinkPad T60 back. IBM will probably refurbish it and send it off to a deserving child in Africa.
If you have an old PC or laptop, please consider donating it to a child, school or charity in your area. To help out a deserving child in Africa or elsewhere, consider contributing to the [One Laptop Per Child] organization.
