As Mike Riley points out on his Netapptips blog today, I was not exactly a fan of Netapp's
guarantee program when it first came out, but now I am an unabashed
supporter. Sometimes other vendors come up with excellent ideas.
Yesterday HDS announced their capacity guarantee program and although it depends heavily on the capacity differences between RAID 1 and RAID 5 (which is a little cheesy), they offer a contract and appear to be ready to put back the program with more than a hand wave. That leaves HP, IBM and EMC (oh wait - and Oracle Sun) as the major storage players who aren't offering a capacity guarantee for customers making a technology refresh on storage.
The question is - are these programs just marketing ploys? Sure they are, just as any customer satisfaction guarantee for any product is a marketing ploy designed to hook customers - whether it's soap, kitchen knives, bass lures, vacuum cleaners, etc, but these ploys and the products behind them are targeted directly at data center operators that are tired of over-spending on storage. All are serious products from some of the biggest names in the storage industry and proven technology leaders. 3PAR's thin technologies (provisioning, conversion, persistence, reclamation and zero-detection) continue to lead our industry.
Depending on the applications and requirements of your data center some of these products and programs will be a better fit than others. All of them should save you money on capacity purchases, but there are other things to consider, such as required software and services. The details of each vendors' programs are different. That said, if you are offered a contract to reduce your storage capacity costs, that's pretty strong negotiating leverage with any other vendor - whether or not they offer a guarantee. And even if you are not ready to make a purchase now, you might want to know how these programs work so you can be better prepared when the time comes.
