Nirvanix, a San Diego, Calif. storage startup, has received an investment for an amount in the “mid-single digit millions” from Intel Capital, according to the company’s CEO.

That follows an investment of $12 million two months ago, at which point the company said it had signed on 40 customers. Nirvanix directly competes with Amazon’s S3, a remote storage and delivery service for online applications like video.
