San Diego-based online storage firm Nirvanix said Monday that it has signed on another user for the firm's services. Nirvanix said that Toronto, Canada-based Ogrant has chosen the firm's services for its school grant and scholarship services, which allow students to send videos and images to schools. Financial impact of the deal was not disclosed. Nirvanix claims Ogrant chose the firm over similar services from Amazon S3. Nirvanix provides storage as a service over the Internet; the firm is a direct competitor to Amazon, which also provides Internet storage through its Amazon S3 services. The company is venture backed by Mission Ventures, Valhalla Partners, and Windward Ventures.
