The Load Balancer Fast Distribution Controller (FDC) T740 provides 40 gigabit per second (Gbps) throughput to boost the availability of applications. Barracuda has built the product on top of Intel technology.
The vendor has separated the ADC's load balancing from the security and access control functions often found in all-in-one devices. Barracuda runs the load balancer in separate hardware for higher performance, while security is left within the virtualized platform used to run applications.
Barracuda's approach is similar to that taken by companies like AVI Networks, according to Dan Conde, analyst for Enterprise Strategy Group. The companies are focused on virtualized data centers that require specially built ADCs.
The T740 ADC appliance can be used with the Barracuda virtual private network or Web filter. The filter is used to screen traffic for malware and other threats.
Barracuda gets a hand from Intel
The T740 uses Intel's Data Plane Development Kit (DPDK) and x86 processors. The DPDK is a programmable forwarding module and application programming interface. Barracuda uses the DPDK's libraries for optimizing Layer 2 and 3 virtual switches found in the infrastructure powering virtualized servers.
Kemp Technologies uses the same Intel technology in its ADC appliance. Vendors selling ADCs or load balancers as software often use Intel processors, Conde said. Intel's DPDK was first shown as a technology for packet processing in telecom infrastructure.
"It's interesting to see its adoption in different data center areas," Conde said.
The Load Balancer FDC T740 has a list price of $20,000 for the appliance. Updates cost an additional $6,300 per year. Customers have the option of paying $7,700 a year to swap out an ADC appliance with new hardware every four years. The service also covers replacements for hardware that fails.
