There were several reasons offered on why someone might pursue a "Do-it-Yourself" course of action.
- Building up skills
In my post [Simply Dinners and Open Storage], I suggested that building a server-as-storage solution based on Sun's OpenSolaris operating system could serve to learn more about [OpenSolaris], and by extension, the Solaris operating system.Like Linux, OpenSolaris is open source and has distributions that run on a variety of chipsets, from Sun's ownSPARC, to commodity x86 and x86-64 hardware. And as I mentioned in my post [Getting off the island], a version of OpenSolaris was even shown to run successfully on the IBM System z mainframe.
"Learning by Doing" is a strong part of the [Constructivism] movement in education. TheOne Laptop Per Child [OLPC] uses this approach. IBM volunteers in Tucson and 40other sites [help young students build robots]constructed from [Lego Mindstorms]building blocks.Edward De Bono uses the term [operacy] to refer to the"skills of doing", preferred over just "knowing" facts and figures.
However, I feel OpenSolaris is late to the game. Linux, Windows and MacOS are all well-established x86-based operating systems that most home office/small office users would be familiar with, and OpenSolaris is positioning itself as "the fourth choice".
In my post[WashingtonGets e-Discovery Wakeup Call], I suggested that the primary motivation for the White House to switch from Lotus Notes over to Microsoft Outlookwas familiarity with Microsoft's offerings. Unfortunately, that also meant abandoning a fully-operational automated email archive system, fora manual do-it-yourself approach copying PST files from journal folders.
Familiarity also explains why other government employees might print out their emails and archive them on paperin filing cabinets. They are familiar with this process, it allows them to treat email in the same manner as they have treated paper documents in the past.
- Cost, Control and Unique Requirements
The last category of reasons can often result if what you want is smaller or bigger than what is availablecommercially. There are minimum entry-points for many vendors. If you want something so small that it is notprofitable, you may end up doing it yourself. On the other end of the scale, both Yahoo and Google ended up building their data centers with a do-it-yourself approach, because no commercial solutions were available atthe time. (IBM now offers [iDataPlex], so that has changed!)
While you could hire a vendor to build a customized solution to meet your unique requirements, it might turn outto be less costly to do-it-yourself. This might also provide some added control over the technologies and components employed. However, as EMC blogger Chuck Hollis correctly pointed out for[Do-it-yourself storage],your solution may not be less costly than existingoff-the-shelf solutions from existing storage vendors, when you factor in scalability and support costs.
Of course, this all assumes that storage admins building the do-it-yourself storage have enough spare time to do so. When was the last time your storage admins had spare time of any kind?Will your storage admins provide the 24x7 support you could get from established storage vendors? Will theybe able to fix the problem fast enough to keep your business running?
From this, I would gather that if you have storage admins more familiar with Solaris than Linux, Windows or MacOS,and select commodity x86 servers from IBM, Sun, HP, or Dell, they could build a solution that has less vendor lock-in than something off-the-shelf from Sun. Let's explore the fears of vendor lock-in further.
- The storage vendor goes out of business
Sun has not been doing so well, so perhaps "open storage" was a way to warn existing Sun storage customers thatbuilding your own may be the next alternative.The New York Times title of their article says it all:["Sun Microsystems Posts Loss and Plans to Reduce Jobs"]. Sun is a big company, so I don't expect them to close their doors entirely this year,but certainly fear of being locked-in to any storage vendor's solution gets worse if you fear the vendor might go out of business.
- The storage vendor will get acquired by a vendor you don't like
We've seen this before. You don't like vendor A, so you buy kit from vendor B, only to have vendor A acquire vendorB after your purchase. Surprise!
- The storage vendor will not support new applications, operating systems, or other new equipment
Here the fear is that the decisions you make today might prevent you from choices you want to make in the future.You might want to upgrade to the latest level of your operating system, but your storage vendor doesn't supportit yet. Or maybe you want to upgrade your SAN to a faster bandwidth speed, like 8 Gbps, but your storage vendordoesn't support it yet. Or perhaps that change would require re-writing lots of scripts using the existingcommand line interfaces (CLI). Or perhaps your admins would require new training for the new configuration.
- The storage vendor will raise prices or charge you more than you expect on follow-on upgrades
For most monolithic storage arrays, adding additional disk capacity means buying it from the same vendor as the controller. I heard of one company recently who tried to order entry-level disk expansion drawer, at a lower price, solely to move the individual disk drives into a higher-end disk system. Guess what? It didn't work. Most storage vendors would not support such mixed configurations.
If you are going to purchase additional storage capacity to an existing disk system, it should cost no more thanthe capacity price rate of your original purchase. IBM offers upgrades at the going market rate, but not all competitors are this nice. Some take advantage of the vendor lock-in, charging more for upgrades and pocketing the difference as profit.
Vendor lock-in represents the obstacles in switching vendors in the event the vendor goes out of business, failsto support new software or hardware in the data center, or charges more than you are comfortable with. These obstacles can make it difficult to switch storage vendors, upgrade your applications, or meet otherbusiness obligations. IBM SANVolume Controller and TotalStorage Productivity Center can help reduce or eliminate many of these concerns. IBMGlobal Services can help you, as much or as little, as you want in this transformation. Here are the four levelsof the do-it-yourself continuum:
|Let me figure it out myself||Tell me what to do||Help me do it||Do it for me|
|This is the self-service approach. Go to our website, download an [IBM Redbook], figure out whatyou need, and order the parts to do-it-yourself.||IBM Global Business Services can help understand your business requirementsand tell you what you need to meet them.||IBM Global Technology Services can help design, assemble and deploy asolution, working with your staff to ensure skill and knowledge transfer.||IBM Managed Storage Services can manage your storage, on-site at your location, or at an IBM facility. IBM provides a varietyof cloud computing and managed hosting services.|
So, if you are currently a Sun server or storage customer concerned about these latest Sun announcements, give IBM a call, we'll help you switch over!
