Database Size Guidelines
FactoryTalk EnergyMetrix writes 16 bytes of data to the database for each meter tag logged. Over time, the database can
grow to become quite large. Some examples include the following:
• A low-end server, logging 40 meter tags at 15 minute intervals, will grow the database at a rate of 2.56 KB per hour or
22 MB per year.
• A mid-level server, logging 320 meter tags at 15 minute intervals, will grow the database at a rate of 20.5 KB per hour,
or 180 MB per year.
• A high-end server, logging 1000 meter tags at 15 minute intervals, will grow the database at a rate of 240 KB per
hour, or 2.1 GB per year.
Consider these guidelines when determining hard disk requirements for a server as well as database maintenance schedules.
Recommendations
These are general guidelines. FactoryTalk EnergyMetrix software is capable of running on a variety of hardware platforms.
The main scalability issue is related to processing of logged data (for example, report generation, trending). CPU speed,
number of CPUs, RAM, and RAID 5 for the database files are the main scalability factors (in that order). All hardware
platforms require the following:
• Processor, RAM and hard drive as noted below
• DVD drive
• One or more Ethernet network ports
• Internet access
• Monitor, keyboard, pointing device (mouse)
• Low-end Server
– Single 2 GHz Pentium 4
– 1…2 GB RAM
– 80 GB hard disk
• Mid-range Server
– 2 or 4 CPU 2 GHz Pentium 4 or better
– 2…4 GB RAM
– 160 GB hard disk (with separate disks for operating system and log files and RAID 5 for main database files
preferred)
• High-end Server
– High-end server requirements are very dependent upon the user's application requirements. Please contact
Rockwell Automation for assistance in specifying hardware for a high-end server.
Client Requirements
The following are the client requirements for compatibility with FactoryTalk EnergyMetrix software:
• Microsoft Windows XP Professional, Vista Professional, Windows 7 (Windows 2000 is not supported) operating
system.
• Internet Explorer 7, 8, or 9 web browser.
