Unified Architecture across multiple hardware form factors and Superior Capacity to handle web transaction loads are enabled with the new ACE30 Module complementing the existing ACE 4710 Appliance. Both the Cisco ACE30 Module and the Cisco ACE 4710 Appliance are powered by the new Cisco ACE Software Release A4(1.0) which introduces new features in addition to providing similar functionality across the two hardware form factors.
The Cisco ACE30 Module for the Cisco Catalyst
® 6500 Series Switches and Cisco 7600 Series Routers is one of the industry-leading application switches, increasing the availability, accelerating the performance, and enhancing the security of data center applications.
The Cisco ACE30 Module allows enterprises and service providers to accomplish four primary IT objectives for application delivery:
• Increase application availability
• Accelerate application performance
• Secure the data center and critical business applications
• Facilitate data center consolidation through the use of fewer servers and load balancers
New Cisco ACE30 Module
The new Cisco ACE30 Module plugs into a single slot of a Cisco Catalyst 6500 Series Switch or Cisco 7600 Series Router.
Cisco ACE30 Module hardware provides the following new and superior features in the module form factor:
• New web application acceleration capability through hardware-based HTTP compression with a maximum throughput of 6 Gbps
• Superior SSL offload performance compared to the Cisco ACE10 and ACE20 Modules, doubling the maximum performance limit
• Improved Layer 4 and 7 performance powered by the latest generation of network processors
New Features in Cisco ACE Software Release A4(1.0)
Cisco ACE Software Release A4(1.0) runs on the new Cisco ACE30 Module and the existing Cisco ACE 4710 appliance. The release does not run on the Cisco ACE10 or ACE20 Module.
Cisco ACE Software Release 4.1.0 adds to existing features in the Cisco ACE Module Software 2(3.0) release train and Cisco ACE 4710 Software 3(2.1) release train, bringing parity to the features available on the two separate hardware form factors: the Cisco ACE30 Module and Cisco ACE 4710 appliance.
The following new features, detailed in Table 1, are available on the Cisco ACE30 Module running Cisco ACE Software Release A4(1.0) in comparison to the Cisco ACE10 or ACE20 Module running Cisco ACE Software Release A2(3.0):
• Application Acceleration
– HTTP Compression: Support for the following output file formats: GZIP (RFC1952), X-GZIP (RFC2616) and ZLIB (aka DEFLATE) RFC1950 for HTTP 1.1
• Application Availability
– In-band TCP Health Checking: Ability to determine the health of server based on Layer 4 TCP analysis of application traffic between ACE and back-end server
– Cipher based load balancing: Distribution of application traffic based on the SSL cipher information
– Efficient HTTP Sticky Load Balancing through Ability to Set Cookie Value in HTTP response from Server to Client
– Improved global application availability through KAL-AP enhancements in Global Server Load Balancing
• Management and Integration
– Ease of configuration for Probes through Probe Port Inheritance
– Syslogs for SIP Load balancing
Table 1. New Features in Cisco ACE 4710 Appliance Running Cisco ACE Software Release 4.1.0
The Cisco ACE30 Module can compress the data being downloaded from the back-end server to the client browser. The compression algorithms supported are ZIP, GZIP, and Deflate. The maximum throughput for compression is 6 Gbps.
Reduces the WAN bandwidth consumption, leading to cost savings and faster download times
In-Band TCP Health Checking
The Cisco ACE30 Module can check the health of an application server before forwarding traffic to it by using the TCP Layer 4 responses from the application server.
Enables more connections to be set up per second because there are no separate health check probes; hence it can serve a higher rate of incoming connections
Cipher-Based Load Balancing
The Cisco ACE30 Module can make load balancing decisions based on the specific SSL cipher or cipher strength used to initiate an SSL session.
Enables traffic distribution to separate server pools based on the SSL encryption method
Cookie Value Specification
The Cisco ACE30 Module can enter a cookie string value of the real server for HTTP cookie insertion when establishing a sticky connection. With this feature enabled, the Cisco ACE inserts the cookie in the Set-Cookie header of the response from the server to the client.
Enables intelligent web serving with stickiness of the same client to the same real server using server-side information
The Cisco ACE30 Module uses this enhancement in global server load balancing, through which the Cisco Global Site Selector (GSS) reports the correct state of a failed Cisco ACE30 Module in the Domain Name System (DNS) response to the client if a redundant Cisco ACE is present in a secondary data center.
Reduces application downtime for end users for a globally load-balanced application due to failure of the primary Cisco ACE in a distributed cluster of Cisco ACE load balancers (one or more in each global site)
Probe Port Inheritance
The Cisco ACE30 Module can dynamically inherit the port number for a probe from the real server specified in a server farm or from the virtual IP address specified in a Layer 3 or 4 class map.
Provides ease of configuration for probing real servers; only a single probe configuration is sufficient to probe a real server on multiple ports or on all virtual IP ports
Syslog Reporting for SIP Load Balancing
The Cisco ACE30 Module can report the Layer 7 processing status for SIP packets as well as the reason for dropping any SIP packet during Layer 7 processing.
Enables the service provider or enterprise IT operator to troubleshoot SIP-based communication
