January 26, 2001, 10:16 AM — Japanese businesses, buffeted by a decade of economic anemia and suffused with the conservatism that permeates IT investment strategies, are cautiously coming around to the use of storage area networks (SAN). But new evidence that the economy may be slipping back into recession and centralized corporate bureaucracies may dampen adoption of SANs on a large scale.
Research institutes and educational customers are early movers to SANs, according to Hirokazu Torikai, a director of sales at ITFOR Inc., a Tokyo-based systems integrator.
"Central Tokyo University is using a SAN because they have the immediate need," said Torikai, who was attending Japan's first storage networking event, Storage Networking World, here this week. The conference was co-sponsored by Computerworld and its parent company, International Data Group.
But currently, SAN users remain a minority in Japan, where many companies use centralized storage and backup methods such as tape drives and hard drives, according to William P. Reardon, area director of storage systems at Milpitas, Calif.-based LSI Logic Inc.
According to Gartner Group Inc.'s Dataquest unit, the storage market in Japan is the fastest growing market in the Asia-Pacific region, where it is projected to grow at nearly 17% per year and reach $4.2 billion by 2003. That growth is being driven by the rapid build-out of communications infrastructure throughout Japan. Japan currently has nearly 61 million wireless subscribers, and, according to Dataquest, the country is Asia's biggest Internet market with total subscribers expected to hit 64.5 million by 2004.
One touted benefit of SANs is that they give users the ability to add more storage capacity without burdening the corporate data center. But some Japanese companies view SANs as the outsourcing of key business functions and remain reluctant to make that move, said Torikai.
"Traditionally, we like to make centralized decisions, and so moving small parts of a business to a SAN is not always feasible. This kind of change for a company is very complex," he said.
Graham Timm, regional director Asia Pacific for Southboro, Mass.,-based Storability Inc. and a conference attendee, said he agreed. "There are some real cultural differences in the way business decisions about IT get made, and you have to respect them," he said.
And while another factor in the slow adoption of SANs is cost, according to Torikai, Japanese companies are being confronted by a unique twist on the need for more storage.
"First there is the double-byte issue," said Timm, referring to the need for added storage when using kanji characters. "Each letter of our [Roman] alphabet takes a single byte of memory, but with Japanese [and Chinese or Korean] characters, you need twice as much storage capacity."
