Isilon's product, which it calls IQ nodes, are a modular NAS array that use the company's proprietary OneFS operating software to store and serve up large digital files that include audio, photos and video content. Nearly one-third of Isilon's customers are in the media business.
Along with Isilon, other clustered NAS vendors include Panasas, NetApp and BluArc. Clustered NAS systems offer a more economical way to build large-scale storage infrastructures without having to invest in proprietary, monolithic arrays. Using the pNFS protocol, a clusters NAS system would be cheaper because it could use commodity servers like building blocks, adding them incrementally to clusters without disruption to the existing system.
EMC offered no details about its Isilon products.
