"Our survey data shows that over the past 12 months, more firms have bought their storage from a single vendor. While this might not be for everyone, it's worth serious consideration for your environment. Maybe you won't get the best price per gigabyte every time, but you'll probably save money in the long run because of simpler management, increased staff specialization, increased capacity utilization, and better customer service."
Dave Raffo, over at Storage Soup, comments on this in his post[Primary storage still means one vendor]. Here's an excerpt:
A Forrester survey of 170 companies ranging from SMBs to large enterprises in North America and Europe found that more than 80 percent bought their primary storage from one vendor over the last year. That includes 64 percent of the companies with more than 500 TB of raw storage.
The report, written by analyst Andrew Reichman, says using more than one primary storage vendor can make it more complex to manage, provision and support the storage environment. And while using multiple vendors can often bring better pricing, buying from one vendor can result in volume discounts.
“You may have tried to contain costs by forcing multiple incumbent vendors to continuously compete against each other, with price as the primary differentiator,” Reichman writes. “This strategy can reduce prices and limit vendor lock-in, but it can also lead to management complexity and poor capacity utilization.”
The report recommends keeping things simple by and using fewer vendors when possible. However, that advice comes with several caveats: buying all storage from one vendor means taking the bad with the good, and some vendors’ product families differ so much “they may as well come from different vendors.”
As if by coincidence, fellow blogger from EMC Chuck Hollis gives his reflections on this same topic. Here's an excerpt:
When it comes to buying storage (or any infrastructure technology, for that matter), there seem to be two camps:
- Best-of-breed (i.e. multivendor): -- buy what's best, get the best price, keep all the vendors on their toes, etc. etc.
- Single vendor: primarily use one vendor's offerings, and hold them accountable for the outcome.
If Chuck had said "multivendor" versus "single vendor", then that would have been a true dichotomy, but interestinglyhe equates best-of-breed with a multivendor approach. Let's consider two examples:
- Disk from one vendor, Tape from another
Here is a multivendor strategy, and if you have a clear idea of what best-of-breed means to you, then you couldpick the best disk in the market, and the best tape in the market. However, I don't think this keeps either vendor"on their toes", or helps you negotiate lower prices by threatening to switch to the other vendor. In shops likethis, the staffing usually matches, so there are disk administration and tape operations, with little or no overlap, andlittle or no interest in retraining to use a new set of gear. It is true that disk-based VTL could be used where real tape libraries are used, but this may not be enough to threaten your existing vendors that you will switch all your disk to tape, or all your tape to disk.
One could argue that the vendor that sells the besttape could be the exact same vendor that sells the best disk. In this case, your multivendor strategy would actuallywork against you, forcing you away from one of your best-of-breed choices.
- Disk and Tape from one vendor for some workloads, Disk and Tape from another vendor for other workloads
Here is a different multivendor strategy. Having disk and tape for the same vendor allows you to take advantageof possible synergies. The IT staff knows how to use the products from both vendors. This strategy does let you keep your vendors "on their toes". You can legitimately threaten to shift your budget from one vendor over another.However, whatever your definition of best-of-breed is, chances are the product from one vendor is, and the other vendor is not. Both meet some lowest common denominator, meeting some minimum set of requirements, which would allow you to swap out one for the other.
I guess I look at it differently. The equipment in your data center should be thought of as a team. Do your servers, storage and software work well together?
While Americans like to celebrate the accomplishments of individual musicians, athletes or executives, it is actually bands that compete against other bands, sports teams that compete against other sport teams, and companies that compete against other companies. Teamwork in the data center is not just for the people who work there, but also for the IT equipment. Just as a new incoming athlete may not get along well with teammates, shiny new equipment may not get along with your existing gear. Conversely, your existing infrastructure may not let the talents or features of your new equipment shine through.
Putting together the best parts from different teams might serve as a great diversion for those who enjoy["fantasy football"], it may not be the best approach for the data center. Instead, focus on managing your data center as a team, perhaps with theuse of IBM TotalStorage Productivity Center to minimize the heterogeneity of your different equipment. Pick an ITvendor that sells "team players" for your servers, storage and software, with broad support for interoperability and compatibility.
