- While they still lack the credibility needed to entice many large corporate users, storage service providers (SSP) that offer data storage capacity on a rental basis continue to grow and will likely be joined by more competitors in the coming months, according to a report released last week by consulting firm Summit Strategies.
Dot-com ventures and other start-up companies that lack money and technical expertise and have unpredictable growth rates are the most likely customers for SSPs, says Boston-based Summit, a finding that reinforces comments made earlier this year by users and analysts when storage rental companies were first emerging in the market.
Paying monthly per-gigabyte rental fees to an SSP gives users the potential ability to scale their storage capacities as business needs dictate, in a manner similar to the way more-established application service providers (ASP) work with their customers.
"I see the hosted-storage model as almost a subset of the whole ASP model," says Summit analyst John Madden, the author of the new study. Both approaches offer users the prospect of increased simplicity and lower IT costs compared with running applications or storage farms internally, he adds.
TechTarget.com, a company that operates a series of IT-oriented informational websites, is a case in point. TechTarget rents its data storage from StorageNetworks, an SSP. The year-old company struck the arrangement in order to get its business up and running more quickly.
"It was one less thing our IT guys had to worry about," says TechTarget CEO Greg Strakosch. "They had a very full plate building [our] web infrastructure from scratch." Since opening in September of last year, the dot-com venture has doubled the amount of storage capacity that it rents from StorageNetworks to reach the current level of 2TB.
But while there's little disagreement that the SSP market is growing rapidly, some analysts contend that handing over management of sensitive data to an SSP is a step that many companies still aren't ready to take.
Gartner Group Inc. in Stamford, Conn., estimates that storage devices will make up 55% of server hardware costs for typical users next year, and Cambridge-based Forrester Research Inc. estimates at least a fivefold growth in storage sales over the next few years. By 2004, said Forrester analyst Joe Butt, the 100 largest companies in the world will have an average storage capacity exceeding 150TB.
But most of the storage growth "will be sopped up by internal installations or [by] ASPs" that are hosting key corporate applications for users, Butt says. Demand for storage rentals "will continue to rise, but it will be a slow rise because [users] are going to be dealing with it in-house," he adds.
Both Butt and Madden agree that SSPs are currently having to deal with a lack of credibility among large customers. But Madden says he expects that to be cured in time as more users take the plunge. "One way or another, the SSP model will take hold, for the same compelling reasons that the broader ASP model is catching on," he says.
Ironically, the battlefield in the storage rental market is expected to be between SSPs and the storage vendors from which they sometimes lease disk space. As demand increases, Madden says, vendors such as EMC and IBM will also likely begin offering capacity rentals, joining pure-play SSPs such as StorageNetworks, StorageWay and CreekPath Systems, none of which sell any storage equipment.
