The Storage Rack: 'Best-in-Class' Can Prove To Be Worst Decision
By Mike Karp

July 15, 2008 — 

If I hear the term “best-in-class” one more time, I’m liable to toss my Internet cookies all over the data center floor.

Just about every vendor I know of provides “best-in-class” products that are the fastest, slickest and most cost-efficient way to solve every storage problem known to man and machine. The problem of course is that their definition of “best” and “class” and my set of definitions tend to differ substantially in almost every case.  

Consider the following scenario, known to every reader and, if you talk in your sleep, to your partners as well.

The vendor’s sales rep has just left your office. You’ve thrown out the free mug, but your admins have gotten their free logo T-shirts and at least they are happy. Now, it’s time for you and your chief technical honchos to do a postmortem on the vendor’s visit.
“He really seems to understand that our storage situation is unique, and his SAN throughput figures were certainly impressive!”

“I like the fact that his product is clearly best-in-class, like our other storage. And if we bought it, we could show our corporate management team that we have best-in-class SAN storage to go with our new best-in-class servers and our new best-in-class NAS platform.”

“Well maybe...  but I’d wait just a bit on sharing that with the CEO if I were you.  We actually have a small problem there... we still haven’t quite gotten best-in-class NAS to play nicely with the best-in-class servers.”

“Really? But you’ve had three months to do the integration testing. I thought all the products we bought were standards-compliant!”

“Yes, of course they were standards-compliant. But it turns out that NAS standards and server standards don’t necessarily care the least bit about one another. And just because this new best-in-class SAN storage is compliant with storage standards, such as SMI-S, doesn’t mean it will play well with the standards-based management framework, or even that it will play well with NAS storage.”

“But what about all the money we were going to save by using standards-compliant hardware? Is that at least working out?”

“Well, yes and no. The storage budget saves money as long as the storage admins only have to manage storage, and the server budget saves money as long as we only have to manage servers. The problem comes when we have to manage storage and servers together.”

“Umm… wasn’t managing servers and storage together fundamental to our whole corporate IT strategy of moving to an on-demand environment? Didn’t we decide that the only way to do that efficiently would be to automate the process, and that standards compliance was fundamental to automating all of our processes? Are you telling me that having multiple “best-in-class products”—if they can’t work together—doesn’t yield a best-in-class data center?”

“Well, yeah. Sorta. But at least it’s still best-in-class.”
I’m not quite sure I know what “best-in-class” actually means, although typically it has something to do with performance. But in most large data centers, the performance of individual systems is far less significant than their cumulative manageability. Also, I don’t recall ever having seen vendor data indicating what happens when two “best-in-class” systems are left running side by side. I’m willing to bet that the cumulative effect is not necessarily one that vendors would like us to know about.

Data center managers who drink the Kool-Aid and go with multiple best-in-class systems are setting themselves up for a big fall. Buying best-in-class SANs plus best-in-class NAS plus best-in-class servers has very little chance of resulting in best-in-class IT, and it has a high probability of delivering just more worst-in-class complexity, with plenty of expense added in.

This expense will come in two doses. First to arrive will be the costs associated with integrating the various best-in-class products with one another in order to manage them efficiently. Then, be prepared for expenses associated with managing the separate products on a day-to-day basis. Considering that operational expenses may already represent six to eight times the purchase price of hardware (at least for the storage), this may not be the best way to go.

“Best-in-class” has nothing more to do with running an optimized IT center than does the tried and false expression, “If it ain’t broke, don’t fix it.”
 
If you have feelings about the best-in-class concept—whether you believe in it or consider it nonsense—please drop me an e-mail. If you write it, I promise to read it.
