Voltaire Revenue Up 7% Sequentially, 54% Year-over-Year

InfiniBand switch maker Voltaire (VOLT) reported quarterly revenues this morning of $16.6 million, a 54% increase from its 2nd quarter of 2009, and it reaffirmed guidance of $67-70 million for 2010 revenue, reassuring investors who were spooked by Mellanox's (MLNX) downward guidance revision last week.

While it is making every effort to play nice with Ethernet, the company was one of the first to release QDR InfiniBand director and switch ports, which has helped its revenue reverse course off a downward trend it hit during 2008 and 2009.
