Sun Microsystems is moving to an indirect sales model in the U.S. for all but about 300 of its largest customers, a step designed to help boost its flagging revenue.

The change means customers who aren't among Sun's biggest U.S. accounts from a revenue perspective will be switched to one of its reseller partners in the coming months, said Tom Wagner, vice president of Sun's North America partner sales organization, in an interview on Tuesday.

"Effectively we're going to go 100 percent 'channel' below the top 300 or so accounts," he said. That means Sun will depend wholly on its partners to generate leads, architect systems, close deals and provide much of the support and services for those customers.

The move will likely be welcomed by Sun's 600 or so channel partners in the U.S. because they will no longer be competing with Sun for business. Sun believes it will give them more motivation to attack areas of the market where Sun's "share of the wallet" is low today, and allow Sun to scale its sales efforts to target those accounts, Wagner said.

It is less clear how the move will be received by customers. "At the end of the day it'll be a 'wait and see' in terms of the customer reaction," Wagner said.

"We have a portfolio of partners who play pretty high up in the value stack and who we believe can provide quality technical support and system engineering resources," he said. But he acknowledged that some customers may have "very specific demands about how we handle their accounts."

"We'll have to deal with that when it comes to it," he said.

The so-called Partner First initiative is limited to the U.S. today and Sun didn't announce any plans to extend it overseas. Companies will sometimes try a new strategy in one region and roll it out worldwide if it's successful.

Sun does about two-thirds of its business through channel partners today and the proportion outside the top 300 accounts is roughly the same, Wagner said. "We're turning over what we believe is a fairly significant amount of our existing business" to the channel, he said.

The plan was announced internally on July 11 and relayed to Sun's partners through a conference call last week, Wagner said. The goal is to complete the transition by the end of this quarter or early next, which means by September or October.
