The ServerIron ADX Series has demonstrated that it can support low-latency switching of application traffic–on the order of 20 microseconds–for response-sensitive applications. For many organizations, reducing latency is key to successfully delivering Web-based applications, improving the end-user experience, and ensuring customer satisfaction.

SEAMLESS TRANSITION TO IPv6
While the ubiquity of the Internet has created vast new opportunities for service providers and enterprises alike, the rapid growth of Internet-enabled devices and applications has led to IPv4 address depletion. This is forcing many organizations to begin serious adoption of IPv6. At the same time, many organizations face regulatory or governance-driven mandates to offer IPv6 services to their customers, but struggle with the cost of a complete network redesign.

The ServerIron ADX Series eases the migration to IPv6 by enabling service providers and enterprises to maximize their existing IPv4-based investments while communicating with the growing IPv6-based world–without requiring “rip-and-replace” upgrades.

IPv6 NAT64 Gateway: The ServerIron ADX Series enables IPv4 networks to interoperate with IPv6 networks via a simple and standards-based NAT64 gateway. This enables both IPv4 clients to communicate with IPv6 networks, as well as new IPv6-based clients to communicate with traditional IPv4 networks–all without requiring forklift upgrades to existing infrastructure.

IPv6 SLB Gateway: The ServerIron ADX Series also allows existing IPv4 applications to be advertised via an IPv6-based Virtual IP (VIP) service. Existing servers and applications can then be slowly migrated to IPv6 on their natural upgrade cycles. ServerIron ADX switches load-balance traffic destined to an IPv6 VIP among IPv4 application servers, enabling such application servers to be upgraded to support IPv6 at an evolutionary rate.

ALWAYS-ON APPLICATION AVAILABILITY
The ServerIron ADX application delivery switches maximize availability and provide non-stop delivery of business-critical applications through a range of capabilities, including:

High availability: The ServerIron ADX Series provides multiple high-availability options to suit varying infrastructure and business needs for overall enhanced application resiliency. Real-time synchronization of sessions between two peer ServerIron ADX units operating in high-availability mode provides protection against system outages. If one device shuts down, then the second device transparently resumes control of client traffic, with no loss to existing sessions or connectivity.

Site redundancy using GSLB: Organizations deploying multiple, geographically disparate data centers can benefit from Global Server Load Balancing (GSLB). This capability allows the ServerIron ADX switches to distribute client traffic among data center sites based on site availability, site load, and several other metrics. The ServerIron ADX switches determine client-to-server proximity by computing the round-trip delay between the client and the data center site. To provide the optimal user experience, the least-loaded, closest available sites to the client are selected to deliver application traffic.

The ServerIron ADX switches also continually monitor data center sites to detect any changes in servers or services due to varying health and traffic conditions. Configurable site load thresholds allow organizations to align health-checking parameters with the server and service capabilities of each site. All of these features work in conjunction with existing DNS as well as DNS Security Extensions (DNSSEC) servers to minimize service disruption and maximize application uptime.

Site redundancy using healthy route injection: The ServerIron ADX Series provides a site redundancy solution for non-DNS–based infrastructures by injecting network routes for healthy VIP from multiple data center locations. These network routes are propagated through routing protocols, such as BGP, IS-IS, and OSPF, enabling clients to connect to the closest available site.

HIGH-PERFORMANCE ARCHITECTURE
The ServerIron ADX application delivery switches provide up to 3 million HTTP connections per second and 70 Gbps of HTTP application traffic throughput. The ServerIron ADX switch also acts as a high-performance proxy for back-end DNS server farms, delivering up to 18 million DNS queries per second. Moreover, the ServerIron ADX switches provide reliable protection against many forms of Denial of Service attacks (DoS), such as DNS attacks and SYN attacks, and offer industry-leading data rates of up to 120 million SYN attack preventions per second while servicing legitimate traffic.

The ServerIron ADX Series has demonstrated that it can support low-latency switching of application traffic–on the order of 20 microseconds–for response-sensitive applications. For many organizations, reducing latency is key to successfully delivering Web-based applications, improving the end-user experience and ensuring customer satisfaction.

The ServerIron ADX Series' performance leadership is based on its scalable and flexible hardware architecture. Its multi-chip, multi-core, high-density architecture is designed to provide the industry's highest performance for application delivery. The design features complete physical and logical separation of data and management planes, and a switching fabric that provides high-speed interconnect among application, management, and interface modules.

Capacity On-Demand: All ServerIron ADX switches can be quickly upgraded in the field using software keys. This allows organizations to enable a full suite of hardware and software options when needed without opening switch cases, which can disrupt service. For example, on an entry-level ServerIron ADX 1000 fixed configuration platform, the performance can be doubled or quadrupled on the box through the simple addition of a software license fully supporting a “pay-as-you-grow” deployment strategy. Additional interface density and advanced software capabilities can also be obtained with license upgrades.
