Sr.J2EE Developer

• The Trellis Real-Time Infrastructure Optimization platform is the total Data Center Infrastructure Management DCIM Solution that reduces the complexity and operating costs of a data center. By identifying, tracking and monitoring assets, as well as analyzing critical data, you can make better decisions to optimize your environment both today and when planning for future changes.
• The total Trellis platform solution minimizes inventory management and asset health management and allows every member of your data center team to view the infrastructure as a whole or by individual assets and quickly access informative data
• Platform Services: The Platform Services enable communication between hardware and software. They are located on the Trellis platform servers and run in the background. These intelligent services ensure that all platform components are accessible by all authorized parties and function within the suite. Within the software piece, the platform modules gather and present data in a meaningful way that allow you to see what is happening in your data center, decide on a plan of action and either resolve a problem or optimize performance.
• Intelligence Engine is the software that runs in the DCIM appliance providing discovery and control of Emerson and non-Emerson devices, and collection and analysis of the real time data from those devices. The Intelligence Engine contains the knowledge for how to communicate with Emerson and non-Emerson devices. The Intelligence Engine communicates with MSS Services running on the platform. Multiple Intelligence Engines can be deployed in the data center environment to provide scalability as the number of devices to be supported grows. The Intelligence Engine supports devices directly attached to serial ports on the DCIM appliance as well as devices connected to the IP network.
• BMS: The device monitoring feature of the Trellis platform has been enhanced to support all monitored devices, including monitored devices of the Building Management System BMS module. This module uses custom element libraries and element library EL synchronization to update the monitoring configurations of devices. The BMS module, included with the symbol library, provides the ability to create custom element libraries so that a common device instance or a BMS device can be used for different sets of data points. This feature is applicable for all the monitored devices in your enterprise
• TSD Redesign this project is done for TSD Optimization and decreasing the traffic between UMG and Platform. The Concept of Change Of Value is introduced in Trellis by which the Datapoint collection has increased from 75K to 300k for 15 minutes interval.
