As IP-based applications become a critical business foundation for these organizations, market demand for cost-effective application acceleration and delivery solutions that maintain optimized and always-on services is growing. Foundry's ServerIron 4G switches meet this demand, and help businesses see an immediate improvement in the performance and uptime of critical applications, including the ones that run on Oracle, BEA, IBM, Microsoft and Web platforms. With Foundry's purpose-built features for such applications, organizations can accelerate the delivery of business-critical services to local and remote users from a global network of data centers.Foundry's ServerIron 4G family of switches maximizes application uptime, security and performance by leveraging highly advanced traffic management and security features. With Foundry's highly integrated and standards-based global server load balancing (GSLB), the ServerIron 4G provides service redundancy across multiple data center locations to ensure business continuity during disasters. Using ASIC-based security feature implementation, the ServerIron 4G protects server farms and applications against near wire-speed Gigabit rate denial of service (Dos) attacks without compromising application performance to legitimate users.Both the ServerIron 4G family of switches shares a common ASIC-based architecture. The ServerIron 4G switch offers data-center class resiliency, and hardware-based security and acceleration features to ensure uptime and protection of business-critical applications.
