The Brilliant Business of Data Storage Networks

Desire and Need

Enterprise equipment purchasers might waffle on the question of whether segregation of storage is necessary or is merely an expensive wish-list item on the balance sheet. But among analysts, who admittedly do not have to justify expenditures, the answer is clear-cut.

David Hill, vice president of storage research at Aberdeen Group, takes a firm stand in the former camp. Citing smoother moving and processing of data, he told the E-Commerce Times that "storage must become a separate entity."

Giga Information Group senior analyst Anders Lofgren could hardly state the case emphatically enough, especially for large enterprises. "We recommend, if they have not implemented network storage, they should definitely do so. Obviously, early on, there will perhaps be additional costs: You have to buy a bunch of switches, and there's a learning curve." But Lofgren noted that once an enterprise consolidates storage in a network architecture, it will benefit from economies of scale as the information archive grows.

Meanwhile, Brad Nisbet, senior research analyst at IDC, observed that reduced administration costs can be another benefit of SAN deployment. "With a SAN, you can theoretically grow your storage capacity without growing your staff. It comes down to looking at the broader picture," he told the E-Commerce Times.

Virtual or Real?

For those companies that are reluctant to shell out capital for an entirely new network setup, software virtualization can be a cheaper alternative to building a physical storage network. By creating a virtual network that pools storage resources across multiple servers, administrators can optimize and better navigate their storage topography without making a heavy investment in hardware.

But Giga's Lofgren told the E-Commerce Times that virtualization is not an important part of the future. Although smaller vendors are playing in the virtualization market, larger vendors have not stepped in yet. Furthermore, according to Lofgren, distorted use of the term to define a variety of products has stripped the word of meaning and undermined its marketing legitimacy. "Vendors are backing away from it," he said.

On the other hand, Laura Koetzle, an infrastructure analyst with Forrester Research, maintains a more sanguine attitude toward virtualization of traditional storage, asserting that a virtual view of storage within a larger network can be just as useful as a discrete physical network dedicated to storage when it comes to allocating unused disk space.

Bottom Line

Indeed, while it is all well and good to say that corporations should buy networked storage solutions, the harsh reality in today's IT climate is that companies' choices may depend as much on cost as on technical specifications. Therefore, it is likely that many enterprises will choose their storage solutions based on short-term necessity, rather than long-term structural planning.

Koetzle suggested that IT buyers ask themselves, "Is the application that I'm building really one that requires a discrete storage network?"

If a majority of buyers answer "no" to that question, network vendors will get hungrier, and further consolidation can be expected in the storage market. If they answer "yes," the market will grow more quickly. Either way, SAN technology is not going away. As IT spending recovers, it will become a must-have for more and more enterprises. The only question is, which companies will be ahead of the curve?
