Giant Firewall Runs Linux

Linux provides the firepower for Crossbeam Systems' United Threat Management firewall for data centers.

Crossbeam Systems has started shipping a massive chassis-style, "unified threat management" (UTM) system based on an open Linux OS. The X-Series UTM server runs the companys Linux-based "XOS" OS, and targets highly scalable firewalls and other security applications for large data centers and service providers.

The X-Series UTM competes with high-end UTM systems such as Juniper Networkss SSG, but is more open, thanks to a Linux-based OS, Crossbeam says.

The companys "XOS" Linux implementation is claimed capable of "seamlessly" unifying the resources of up to 100 separate processing cores spread out over up to 14 blades, enabling admins to tune available resources for optimal processing of specific individual traffic streams.
