When you buy a car do you get all the gas for it up front? Do you buy all the cafe lattes you are going to drink for the next 3 years all at once - and save them for whenever?
Animals hoard things, like nuts, for instance. Under unusual economic pressures, people sometimes hoard things too. But we shouldn't have to worry about disk drives. There seem to be plenty of them to go around.
Regardless, many customers hoard storage capacity because their technology choices limit their behavior. When they buy storage they make best-guess estimates about how much they will need and then hope the estimates are close because it's such a pain when they are off. You know what I'm talking about.
Thin provisioning makes all that a huge waste of time by letting customers buy only what they need when they buy it and allowing them to add more without spending weekends-at-work to make it happen. 3PAR has been providing thin provisioning to customers that don't want to over-buy storage for the last 5 years and we continue to lead the development of thin technology. We also lead the industry in wide striping - a disk layout technology that delivers optimal I/O performance from every disk drive in a system.
These days we are very excited by the promise of reclaiming storage - which is a way to return unused storage capacity from a file system back to the array's available capacity. This is an example of what we call "getting thin". We are happy to see Symantec's Storage Foundation emerge as the "thin" leader from the server-software side of the industry.
There are plenty of disk drives - we won't run out. So with the current economic climate, do you want to over-buy on your next storage purchase or would you rather spend less and get more in return?
