San Diego-based online data cloud storage provider Nirvanix has secured $5 million in capital out of a $6 million secondary round of venture funding, according to a filing today with the Securities and Exchange Commission. The company, which was previously known as Streamload, aims to compete with Amazon’s (Nasdaq: [[ticker:AMZN]]) S3 storage web service. Nirvanix replaced Patrick Harr with Jim Zierick as CEO in January. Previously Nirvanix raised $12 million in October 2007 from Mission Ventures, Valhalla Partners, and Windward Ventures. Nirvanix said at the end of 2007 it had added Intel Capital and European Partners Fund as investors, but did not disclose the amount of those investments.
