Equalizer Family Standard Features

Equalizer supports the latest version of EQ/OS the Equalizer software. The latest Version of EQ/OS is also supported on the previous `si' hardware line, allowing current customers with existing hardware to continue to take advantage of the continuing innovations provided in by Coyote Point. These innovations include:

• A dynamic web-based graphical Administrative Interface based on state-of-the-art AJAX technology. The Version 8.5 GUI provides up-to-the-minute information, updating the display with current status information and statistics.
• The managed port interface allows you to manage the configuration of the ports on Equalizer's front panel from the GUI, and provides accurate status information as well.
• Custom header injection lets you specify a custom header to be inserted into all client requests - this allows application-specific information to be placed into the client request headers and communicated to the server.
• Equalizer offers 7 load balancing policies, including a custom policy that allows you to specify the mix of load balancing factors that is right for your application.
• Equalizer's Smart Control feature allows administrators to define Smart Events that automate common administrative functions based on pre-set threshold values for system parameters and statistics. For example, you could specify that when the number of active servers in a particular cluster falls below a certain number, a currently unused server is made active.
• The Responders feature lets you define automatic responses to client requests that arrive when all the servers in a cluster are unavailable. Without Responders, you would need to dedicate a server to handle such requests.
• A series of server health checks can be used to probe server availability and performance. By default, ICMP (ping) and TCP connection probes are used. You can also enable content-verification probes that test for response content from the server. Server agent probes allow you to run query the server for the output of a custom script running on the server for health information. Finally, if you are working in a VMware virtual server environment, you can use Equalizer VLB probes to get detailed server status information from VMware.
• Equalizer's event logging mechanism records system events in a syslog format, and allows you to write the Equalizer logs to another system running a syslogd server.
• Real-time statistics gathering permits you to view current statistics as well as graph statistics trends over time. Statistics can be exported to a CSV file for external analysis, and are made available via SNMP (Simple Network Management Protocol) for download to an SNMP client running on another machine.
• Equalizer VLB is Coyote Point's virtualization enabled load balancing solution for VMware Infrastructure virtual server configurations. It is available with either a Basic or Advanced license. VLB basic and comes standard on all Equalizer GX appliances. The Basic product lets you gather detailed status information from VMware, while VLB Advanced extends this functionality by allowing you to control VMware virtual servers via VMware-specific Smart Control Event features.
