InfoStor - ONStor takes a shot at NetApp:

Known primarily as a vendor of NAS gateways, ONStor this week introduced its first complete NAS system, dubbed Pantera. Built on the company's bobcat NAS gateway architecture, Pantera adds Dot Hill disks arrays with two classes of drives. Although Pantera uses the same back-end storage that Network Appliance uses on some of its systems, ONStor claims that its integrated NAS systems offer higher performance, better scalability than NetApp's midrange filers, and in some cases a 50% lower price tag.
