 Enterprise Management Appliance for XenServerQuorum's Enterprise Management Appliance for XenServer™ is a turnkey system that delivers all the management functionality you need to effectively use XenEnterprise for running business applications in production. At the core of Quorum's EMAX appliance is an easy to configure policy engine, which is both flexible and granular, that allows XenServer administrators to effectively and efficiently monitor, manage and optimize XenServer virtualized server environments automatically based on pre-defined service levels. Benefits of Quorum's EMAXEMAX offers the following features for XenServer virtualized server environments:
In-Context High Availability refers to high availability of application workloads to ensure maximum user productivity. An example of how Quorum's EMAX accomplishes In-Context High Availability includes the ability to power up a specified virtual machine (VM), a clone of a physical machine, immediately upon detecting a failure of the physical machine. Once the VM is up and running, any applications that were running on the physical machine can be automatically launched on the VM. Another area in which EMAX showcases its effectiveness is application health monitoring and management. For example, a frequently used business-critical application running in a XenServer VM begins to show a noticeable degree of latency due to excessive use of resources, such as memory. Using EMAX, the health of the application would be continuously monitored so that if a rise in memory consumption was detected that lasted beyond a preset period of time, a policy would be invoked to stop the application and then start a new instance of the application, minimizing the adverse affects on user productivity that would have resulted from the latency detected in the initial instance of the application. Quorum's EMAX is also highly effective at managing virtual resources. Consider a processor-intensive application running on two VMs, both of which are running on a single XenServer host system, with EMAX continuously monitoring the CPU utilization of both VMs as well as the XenServer host itself. In the event that CPU utilization begins to spike above a predefined threshold on one of the VMs, a policy would be invoked that triggers one of the VMs to be XenMotioned to another XenServer host with available CPU resources. Quorum's EMAX ensures business continuity and agility through a variety of methods, including XenServer high availability, restarting applications on VMs or restarting VMs on secondary or backup XenServer hosts when application or VM failures are detected; consolidating servers by XenMotioning VMs on underutilized XenServer hosts to a single XenServer host and shutting down the underutilized XenServer hosts to conserve resources; and reporting and acting upon quality of service metrics to ensure optimal application and/or system health and performance.
