San Diego-based Nirvanix, which operates an online, storage-as-a-service which competes against Amazon's S3 storage service, has shuffled its CEOs, the firm said today, replacing CEO Patrick Harr with Jim Zierick. Nirvanix is venture backed by European Founders Fund, Intel Capital, Mission Ventures, Valhalla Partners, and Windward Ventures. Nirvanix said that Harr is leaving to "pursue a new opportunity." Zierick was most recently CEO of Asprya, and also served as CEO of LogicalApps.

The firm charges by bandwidth and amount of storage, and competes against Amazon's S3 service. Nirvanix is backed by European Founders Fund, Intel Capital, Mission Ventures, Valhalla Partners, and Windward Ventures. San Diego-based Nirvanix, a provider of storage-as-a-service, said Tuesday that the firm's technology is being used by video delivery firm Ooyala. According to Nirvanix, Ooyala is using Nirvanix to help its customers store and manage HD-quality video.
