Coyote Point VLB Advanced

Virtualized Servers and Applications

Virtualization is emerging as a key technology enabling efficient, cost-effective server deployment. Coyote Point, a pioneer in load balancing, application delivery and application acceleration technology continues to lead the pack by offering comprehensive solutions for enhancing load balancing of virtual servers and applications.

Superior Application Delivery in a Virtual World

Equalizer VLB™ and Equalizer VLB Advanced™ are software enabled application delivery solutions optimized for load balancing VMware Infrastructure™. Equalizer guarantees the uptime of applications delivered by virtual servers and real servers alike. This provides a comprehensive load balancing and application acceleration solution for today's organizations that require 100% application availability. Advanced solutions like redundancy, business continuity and application acceleration can also be addressed in a virtual infrastructure by proven Equalizer functionality. IT business leaders can now ensure optimum use of virtual hardware resources by effectively managing resource provisioning of physical servers . Hot spots and the need to overprovision to handle load spikes are eliminated. The fiscal impact is both in reducing capital expenses (fewer servers) as well as reducing operational expenses (power, cooling, and management). Improved plotting in the Equalizer GUI allows these new load balancing methods to be easily monitored. Combine this with the highest application availability, improved application response times and you have a complete solution that enhances the success of a virtual server environment.

Equalizer VLB and VMware® Servers

Coyote Point Equalizers with VLB configured monitor VMware vCenter or ESX server (VMware infrastructure) to determine virtual machine status. Combining our proven expertise, awareness of application availability and server traffic trends with VMware's ability to monitor the VMware servers and physical resource utilization allows higher application performance and availability to be achieved compared to load balancing and virtualization working independently. Equalizer VLB utilizes VMware's management API to retrieve the real-time virtual server performance information from VMware. This VMware information is combined with Coyote Point's application and network aware capabilities to manage the traffic flowing to VMware Virtual Machines running on ESX server.

• Equalizer VLB utilizes performance metrics via the VMware Infrastructure API
• Equalizer VLB monitors virtualized application performance and availability invisible to VMware.
• Guarantees Uptime and Business Continuity by eliminating single points of failure

Make Equalizer your automated NOC managers

Equalizer VLB Advanced enhances the VLB feature-set, and also adds several features which allow VLB to control the behavior of the virtual machines, in addition to the behavior of the traffic for those virtual machines. Coyote Point has taken load balancing VMware infrastructure to the next level with Equalizer VLB Advanced. Equalizer VLB Advanced is an option for the E350GX, E450GX, and ships as a standard feature of the E650GX.

• Equalizer VLB Advanced offers VLB Smart Control threshold capabilities.
• Enables monitoring and controlling application performance and server responses
• Allows for automated VMware responses to application-centric events

The Result; higher performing applications, reduced capital expenses (fewer servers) as well as reducing operational expenses (power, cooling, and management).

Available on all Layer 7 Models, Included with E650GX
 

EqualizerVLB Advanced with Smart Control goes beyond load balancing.

Administrators can define threshold conditions for parameters that will trigger a VMware response. The actions and triggers supported by VLB Smart Control include:

Auto-quiesce trigger events for multiple applications running on the same server, in different clusters, VLB will auto-quiesce servers that are not currently needed due to low traffic, freeing resources for other applications or to permit powering down unused physical servers.

Auto-shutdown & Auto-on event triggers can automatically shut down or start a virtual server when the trigger event occurs. This means that Equalizer VLB will tell the VMware ESX Server or vCenter to shut down a virtual server allowing VMware to then use the resources for other virtual machines. This is particularly important for VMware configurations using VMotion to migrate idle virtual servers to another physical server. VLB monitors application performance and availability invisible to VMware. This allows automated VMware responses to application centric events such as an application that stops running (has crashed).

Auto-reboot triggers ask the VMware ESX Server or vCenter to reboot a virtual server to restart a "crashed" application.

Auto-minimum triggers help if a server in a VLB enabled cluster goes down, and the number of currently active servers falls below a pre-set minimum to do one of the following: power-on a server, unquiesce a server or activate a warm-spare server. All smart controls can be configured to send administrators a message when triggered.

Equalizer guarantees the uptime of applications delivered by virtual servers while providing comprehensive, proactive management and optimization of virtualized applications and services.
