Feature:

¡¹ServerIron 4G Platform Features

• Compact and Resilient Design: The ServerIron 4G features resilient fixed-configuration switches in a compact space saving size (1.5 RU high) making it simple to replace appliance products and servers.

• DataCenter-Class Redundancy: Delivering high availability and non-stop networking is of utmost importance in network application delivery. Hardware redundancy features such as redundant, removable and hot swappable AC & DC power supplies are critical for maximum uptime

• Integrated SSL Acceleration Option: The ServerIron 4G-SSL system is embedded with integrated hardware SSL acceleration for secure Web applications

• Flexible Connectivity Options: With four ports of Gigabit copper and fiber combination, and 100 Mbps copper connectivity options, the ServerIron 4G switch offers maximum flexibility for deployment in most networks.

• The ServerIron 4G-SSL-FIPS comes with a FIPS (Federal Information Processing Standard) 140-2 Level 2 certified SSL accelerator. The FIPS standard specifies the security requirements that are to be satisfied by a cryptographic module utilized within a security system protecting unclassified information within computer and telecommunication systems (including voice systems).

¡¹ServerIron 4G Series Product Features

Traffic Management

• Extensive Layer 7 Features: Rich application intelligence, including URL, cookies, HTTP headers, XML tags, SSL session IDs, request type, and SIP/VoIP traffic, to deliver application scalability, security and acceleration.

• Superior Connection Performance: ServerIron 4G switches deliver unprecedented application transaction performance in class with support for up to 40,000 connections per second.

• Advanced Load Balancing: A rich set of methods to load balance client traffic to multiple servers to increase availability and scalability of critical applications.

• Sophisticated Health Monitoring from Layer 2 through 7: Customizable server and application health monitoring permits rapid failure detection and service recovery to maintain maximum uptime

• Hardware and Software Based Hitless Failover: High availability features such as Virtual Router Redundancy Protocol, multi-switch session mirroring and redundant management modules with session synchronization maximize uptime in the most critical environments.

¡¹Web Acceleration

• Integrated Hardware SSL Acceleration: With the SSL integrated model, the ServerIron 4G series delivers superior performance and server SSL offload for secure Web transactions and other SSL-enabled applications.

• HTTP Connection Multiplexing for Server Optimization: ServerIrons HTTP connection multiplexing eliminates the need for servers to sustain large connection load. Server connection load reduction increases service performance and ultimately the cost of server upgrades.

• Clientless Bandwidth Optimization with Compression: Using standards-based clientless browser compression to transparently condense content provided by the server on return, the ServerIron reduces bandwidth utilization and decreases download times.

• End-to-End SSL Support: For high security applications, the Web accelerators can terminate SSL, process content in the Layer 4-7 engine, and re-encrypt traffic to the back-end servers for total security and confidentiality.

• Centralized Certificate Management: Provides added security, easy manageability and investment savings from multiple certificates. Client side certificates and revocation lists prevent illegal use and abuse of SSL applications.

¡¹Security

• Superior DoS/DDoS Protection: Wire-speed Gigabit rate DDoS/DoS attack protection, including protection against SYN/ACK flood attacks up to 1.2 million TCP SYN packets per second for uncompromising application performance with robust protection.

• Granular Application Level Rate Limiting: ServerIron switches can control amount of traffic a particular client is sending to a server, which prevents abuse and attacks while increasing the availability of applications without blocking legitimate traffic.

• E-Mail Spam Mitigation: The switches feature advanced policy-based SPAM mitigation with. E-mail SPAM can be blocked, permitted or redirected based upon millions of good, bad or unknown IP reputation policies.

• Advanced Web Firewall: The Web Firewall features fully inspect Web transactions to protect Web servers from buffer overflow, cross-site scripting, cookie poisoning, forceful browsing and other attacks. Server cloaking hides server and application identity to prevent targeted attacks.

• FIPS 140-2 Level 2 certification for SSL acceleration on ServerIron 4G-SSL-FIPS

¡¹Global Load Balancing

• Global Server Load Balancing (Multi-Site Redundancy): The ServerIron switches can be enabled for this application with the premium TrafficWorks OS version to offer multi-site redundancy and scalability for IP and Web applications using standards-based DNS and IP routing.

• Total Transparency to Existing DNS Solution: Works with the existing DNS servers left in place with standards-based interoperability to protect the investment of the current infrastructure. The ServerIron offers increased and independent scaling of the global DNS performance.

• Intelligent Traffic Distribution and Persistence: With advanced site load distribution features such as weighted and proximity metrics, and adaptable site specific configurations can be created to provide content localization and efficient traffic delivery.

• Secure Communication between Sites: The ServerIron utilizes a secure GLSB protocol with authentication and encryption to prevent attacks against the infrastructure global data center infrastructure.

¡¹Voice Over IP / SIP Load Balancing

• Advanced SIP/VoIP Intelligence and Protocol Support: As more voice services become standardized on SIP, the importance of high availability increases. The ServerIron software is "SIP Aware" for maximum voice availability.

• SIP Proxy/Registrar Load Balancing and Persistence: The ServerIron protects the SIP servers from unwanted traffic and load balances REGISTER and INVITE messages to multiple registrar servers while keeping persistence via the Call ID.

• SIP Specific L7 Health Monitoring: The ServerIron has SIP aware health monitoring and will sends periodic SIP messages to the servers to ensure that only servers with responsive application are used for client traffic

¡¹Advanced L2/3

• Integrated Full-Function Layer 2/3 Switching and Routing: Industrys most comprehensive Layer 4-7 switching platform with advanced Layer 2/3 switching and routing for cost-effective and simplified network design with device consolidation. Wire-speed layer 2/3 performance for traffic not targeted to the application servers.

• sFlow Network Monitoring: Industrys only Layer 4-7 switch with hardware-assisted standards-based and always-on sFlow network traffic monitoring on application flows and Layer 2/3 switched traffic.

• High Performance Stateful IP NAT: Deploying network address translation on the ServerIron protects servers and reduces load on the high cost firewalls
