The decision to ask some storage vendors to not attend VMware PEX is odd given that EMC's stated plan all along was to keep VMware independent, Baldwin said.
"We like Veeam, and we like VMware, and they work well together," he said. "You have to sell what customers want."
This situation appears to be an overreaction on VMware’s part, said another solution provider who asked to remain anonymous.
"We expect to go to Partner Exchange to hear from different technologies and see how they fit going forward," the solution provider said. "We're the partners. Whoever goes there, even if competitive in nature, wants to support the VMware platform."
This is not the first time VMware has limited or excluded participation in one of its events.
VMware in 2009 confined both Microsoft and Citrix to small 10-x-10-foot booths at that year's VMworld conference, and shut them out of the kind of promotional opportunities offered to exhibitors, which would normally pay extra for larger booths, and especially for sponsorship activities.
Both vendors were gold-level sponsors at VMworld 2008.
Doug Hazelman, vice president of product strategy for Veeam, said his company's original plan was to sponsor VMware PEX at the gold level, but that has changed.
Hazelman declined to say who decided Veeam could not attend. "It's not our decision," he said. "Until Thursday of last week, we were planning to send a whole team."
VMware appears to be selective about who can come to its partner conference. The VMware PEX sponsor list includes several companies that compete with Veeam -- and with VMware -- for data protection technology, including Symantec, Zerto and PHD Virtual, which last month was acquired by Unitrends.
Hazelman said that Veeam remains a member of VMware's technical alliance program, and has assurances it will be a gold sponsor of this year's U.S. and European VMworld conferences. The U.S. VMworld conference is scheduled to be held in San Francisco this coming August.
Veeam also will be in San Francisco during VMware PEX. "We'll be in San Francisco to talk to partners and to recruit additional partners," Hazelman said.
Veeam remains committed to the channel, and is on a growth path that has not slowed at all in the past year, he said. "We hit our targets in 2013," he said. "This is in no way a reflection of Veeam's growth."
