Meter data management system supports more than 9.6 million meters


Liberty Lake, WA, U.S.A. — (METERING.COM) — January 23, 2009 – Another successful round of scalability and performance benchmark testing for Itron’s Enterprise Edition (IEE) Meter Data Management (MDM) product has confirmed the software’s ability to support advanced metering system (AMI) installations of more than 9.6 million hourly meters.

This represents the largest scale independent testing in the meter data management industry to date.

Itron worked with Agilysys, Arrow Enterprise Computing Solutions, HP, and Infosys to execute the latest benchmark on Oracle® Database Enterprise Edition.
The results showed that IEE on Oracle needs less than three hours to validate, auto-estimate, and import 4.8 million half-hourly meters, each having one register and one interval channel – a volume equivalent to hourly data for 9.6 million meters. The test included calculating estimations for 0.5 percent to 10 percent of the meters.

The testing took into account the full range of data processing requirements for large-scale AMI deployments, including interval meter data import, data validation, estimation and storage, as well as the daily demand for time-of-use (TOU) calculations and billing exports (500,000/day, assuming 20 cycle days per month). Using IEE MDM high volume AMI import and export services, the level of performance and scalability required to exceed the demands of full-scale AMI deployments was achieved.

“Benchmarking to this scale year after year, release after release, requires a significant investment, but the investment is more than worthwhile,” said Julie Hance, vice president of Itron software solutions. “Our highest-ever volume has been achieved in this recent benchmark.”

Itron additionally tested and verified that IEE Mass Market Customer Care, its product for providing web presentment via portlet technology for customer service and end-consumer usage, can scale to meet the demands of thousands of concurrent AMI users (2.75 second average response time; 1,800 users per web server). Testing also included virtualization software on the application servers with no impact on processing and throughput.

Agilysys assisted with the infrastructure design, project managed the benchmark, and provided ongoing Oracle support, as well as UNIX and Windows operating system support. Testing and development was done using Infosys AMI Center of Excellence resources and testing was completed entirely on an HP Integrity mission-critical enterprise server with Intel® Itanium® processors running HP-UX 11i v3 operating system, and utilized an HP StorageWorks Enterprise Virtual Array and blade servers for validation/estimation. The benchmark tests were performed at the Arrow Enterprise Computing Solutions’ Solutions Center in Alpharetta, Ga.
