Despite these problems, the exec tells Byte and Switch that Isilon now has around 600 customers, double the size of its customer list 12 months ago.
The vendor nonetheless faces stiff competition from its rivals, notably EMC with its high-end Celerra products, and NetApp with its 6000 Series.
Traditionally, Isilon has aimed its products at specialist users, mainly Web 2.0 companies such as MySpace and Kodak EasyShare, but the supplier is now looking to target more traditional enterprises, according to Brad Nisbet, research manager at IDC.
"The major vendors don't necessarily have competitive products, but they do recognize this [part of the market] as an opportunity," says Nisbet, pointing to EMC's planned "Hulk" and "Maui" products and NetApp's focus on developing its Ontap GX technology.
"There's another set of customers that continue to emerge as an opportunity for Isilon and others that are more traditional enterprises experiencing an influx of file-based data," he says. "It's word documents, and spreadsheets, and the proliferation of these via email."
