To access and use the application, your system should be equipped with the following:

  • 400 MHz processor (minimum) or faster (recommended)
  • 128 MB RAM (minimum) or more (recommended)
  • 500 MB free disk space (minimum) or more (recommended for reports)
  • 800 x 600 display setting

Recommended:

  • Small font size
  • 1024x768 pixels desktop area

One of the following operating systems:

  • Windows 7
  • Windows 2000 Professional
  • Windows XP Home/Professional
  • Windows Vista Home Basic/Business/Ultimate
  • Windows 2003 Server
  • Windows Server 2008

Recommended Browser:

  • Microsoft® Internet Explorer  7.0 or later; Firefox® 3.5 or later; Google® Chrome

NOTE: Minimum system requirements may vary depending on the operating platform installation (Desktop or Network), and antcipated size of the organization database. Contact EnergyCAP, Inc. with specific questions regarding your implementation.

Database Management

Required: SQL Server 2005 or later

  • 32 or 64 bit supported
  • Local user authentication or mixed mode required

Hardware specifications are dependent upon database size, features utilized, and desired performance. Database server should not host any applications besides SQL.

RAID Drive Setup:

In accordance with Microsoft’s suggested SQL Server setup, EnergyCAP, Inc recommends that the operating system, the log files, and the data files all exist on separate independent disk channels.  Although the database server will likely perform adequately in a less optimal configuration, better performance will be observed when adhering to the basic guidelines below.  Consult with your organization DBA regarding requirements or setup configurations that enhance this basic standard.

DB Performance Guidelines

Fewer than 1,500 meters:

  • Xeon Dual/Quad-core, 2.0  GHz or better, 2 GB RAM, 5 GB* hard drive space

Over 1,500 and fewer than 3,000 meters

  • Xeon Dual/Quad Core, 2.5 GHz or better, 3 GB RAM, 10 GB* hard drive

Over 3,000 meters

  • Dual Xeon processors, Dual/Quad Core, 2.5GHz or better, 4+ GB RAM, 30 GB* hard drive, suggested RAID configuration

A more capable server will be needed for organizations with:

  • Over five years of historical bills
  • Over 50 interval data channels
  • Frequent data imports

*Analyzing numerous client databases with historical and active data, a general “rule of thumb” shows that an EnergyCAP database will grow at approximately 20Kb/bill for bill data only.  This translates to rough estimates of:

  • 500 bills/month   = 6,000/year   = ~120MB/year
  • 1000 bills/month = 12,000/year = ~240MB/year
  • 1500 bills/month = 18,000/year = ~360MB/year
  • 2000 bills/month = 24,000/year = ~480MB/year
  • 5000 bills/month = 60,000/year = ~1.2GB/year

Performance Guidelines

For best performance on a server, SQL Server should be the only application running on the server, other than management utilities. Don't locate IIS or MTS server on the same server as SQL Server. Not only does this hurt SQL Server's performance, but it also makes it more difficult to performance tune and troubleshoot SQL Server.

RAM - This is probably the most significant piece of hardware that affects SQL Server's performance.  Ideally, the entire database should fit into RAM; therefore, ECI recommends installing all the RAM the server can handle. There is no such thing as too much RAM.

I/O Subsystem - After RAM, the I/O subsystem is the most important piece of hardware to affect SQL Server's performance.  At the very minimum, purchase hardware-based RAID for the database.  As a rule of thumb, ECI recommends installing more, smaller drives, not fewer, larger drives in the array.

Network Connection - At the server, have at least one 1GB network card, and it should be connected to a switch.

Hardware specifications are dependent upon database size, features utilized, and desired performance.  The database server should not host any applications other than SQL.

Web Server Minimum Specifications

  • Windows 2003 Web/Standard/Enterprise or greater
  • 1GB RAM
  • Xeon Dual/Quad core, 1.6GHz or better
  • ASP enabled
  • .NET 3.5 or greater
  • IIS 6.0 or greater
  • Port determined by web admin

The web server can be shared with other web services or on the database server; however, network/security administration standards usually recommend not having the application/Web server running on a database server.

NOTE: EnergyCAP uses the Crystal Report Runtime engine, which may interfere with other Web applications.  Although many clients have successfully installed EnergyCAP online alongside other web applications, ECI cannot support issues caused by other applications running on the same server.
