Linux has proven itself to be a versatile solution across a variety of hardware architectures to support workloads ranging from basic infrastructure services to enterprise-class database deployments. Today, Linux is commonly found operating in some capacity within most larger organizations, and over time, it has captured many of the same workloads that previously were deployed aboard RISC platforms running Unix operating systems.

Last month, SonicWall rolled out its next-generation unified threat management firewall appliance geared for the enterprise. In our exclusive test of the Network Security Appliance E7500, results show that SonicWall has, indeed, crashed through the speed barrier.
This box offers 1.3Gbps of UTM performance, which is nearly triple the speed of the fastest product in our comparative UTM test last November (See comparative UTM test).
While SonicWall has not changed much on the surface of its firewall, there are dramatic differences in the internal architecture that yield performance gains that leapfrog the throughput numbers of the SonicWall Pro product line. This makes UTM features including intrusion-prevention system (IPS), antivirus, antispyware, and content filtering cost-effective because they can run at gigabit speeds. (Compare UTM products in UTM Buyer’s Guide.)
SonicWall's NSA firewall line, based on a family of multi-core security processors from Cavium, is called the company's "generation 5 product." The new hardware (six models have been announced already) is slated to entirely replace the company's old Pro series.

The high-end E7500 that we tested has a 16-core Cavium CPU, with each core operating at 600MHz. One core is dedicated to system management, while the other 15 are used for security processing, including firewall, VPN and other UTM features such as antivirus, IPS and content filtering. Also built into the CPU is hardware acceleration for cryptography (useful in VPNs), compression, and regular expressions, which compare a pattern against a string, and are heavily used in most IPS rule sets. SonicWall claims it took 18 months to port its existing operating system to effectively make use of the multicore capabilities of the new hardware.

New appliance from SonicWallBy Anonymous on April 23, 2008, 5:29 pmInteresting read, however they will also claim to be an application layer firewall and they are not.
