•SYN-Guard: Protects server farms against multiple forms of DoS attacks, such as

TCPSYN and ACK attacks, by monitoring and tracking session flows. Only valid

connection requests are actually sent to servers. ServerIron ADX switches are

capable of defeating DoS attacks at the industry’s highest rate of up to 120 million

SYN/sec.

•High-availability application switching: Utilizes active-standby mode, whereby the

standby ServerIron ADX switch assumes control and preserves the state of existing

sessions in the event the primary load-balancing device fails. In active-active mode,

both ServerIron ADX switches work simultaneously and provide a backup for each

other while supporting stateful failover.

•HTTP multiplexing (server connection offload): Increases server performance,

availability, response time, and security by offloading connection management from

the servers. Using persistent HTTP 1.0 and 1.1 connections to the server, ServerIron

ADX switches stream a large number of client connections to very few server

connections. Connection offload enables the servers to dedicate resources for high-

performance application content delivery.

•Application rate limiting: Protects server farms by controlling the rate of TCP and UDP

connections on an application-port basis, thereby guarding against malicious attacks

from high-bandwidth users.

•High-performance access control: Uses extended ACLs to restrict access to specific

applications from a given address or subnet.

•Application redirection: Uses HTTP redirect to send traffic to remote servers if the

requested service or content is not available on the local server farm.

•Hardware SSL acceleration: Utilize dedicated SSL hardware for high-performance SSL

offload, both in SSL terminate and proxy modes

•Advanced firewall and security device load balancing: Increases firewall and

perimeter security performance by distributing Internet traffic loads across multiple

firewalls and other perimeter security appliances. This approach overcomes

scalability limitations, increases throughput, and improves resiliency by eliminating

perimeter security devices—such as firewalls, anti-virus gateways, VPN devices, and

intrusion appliances—as single points of failure.

•Transparent Cache Switching (TCS): Balances Web traffic across multiple caches,

eliminating the need to configure each client browser, improving Internet response

time, decreasing WAN access costs, and increasing overall Web caching solution

resiliency. ServerIron ADX switches improve service availability by implementing

cache health checking, redirecting client requests to the next available cache server

or directly to the origin server in the event of a cache or server farm failure.

QDo ServerIron ADX switches provide SSL offload and application server acceleration?

AThe ServerIron ADX 1000, 4000, and 10000 series, provide industry-leading high-

performance SSL offload, in both SSL terminate and SSL proxy modes. The ADX 1000

models 1008-1, 1016-2, 1016-4 and 1216-4, that is shipped post February 1st, 2010, is

shipped with built-in SSL hardware and can be upgraded for SSL offload through simple

software license upgrade. The ADX 4000 and ADX 10000 chassis can be field-upgraded
