Server Software Requirements for Installing FactoryTalk EnergyMetrix
 Windows 2003 Server or Windows 2008 Server, Application Server role. For 64-bit
operating systems, RSLinx Classic version 2.60 (CPR9 SR6) or later must be
installed. Windows 2000 Server is not supported.
 Microsoft SQL Server 2005 or 2008, installed with mixed-mode authentication
(Windows and SQL). TCP/IP access must be enabled. A system administrator SQL
login must be used for the FactoryTalk EnergyMetrix installation.
 You must have machine administrator privileges to install FactoryTalk EnergyMetrix.
Hardware Requirements
These are the hardware requirements that you need to use FactoryTalk EnergyMetrix
software.
Definitions
The following rules of thumb are offered as a starting point for determining server sizing
for FactoryTalk EnergyMetrix. Other factors will affect the required size of a server. A
higher number of tags being logged, a faster log rate, a larger number of users and a larger
number of reports being run will require a more powerful server than the guidelines
specify.
 A low-end server has up to 8 meters and logs up to 40 meter tags at a minimum 15
minute log rate
 A mid-range server has up to 64 meters and logs up to 320 meter tags at a minimum
15 minute log rate
 A high-end server has more than 64 meters and logs more than 500 meter tags at a
minimum 15 minute log rate
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:
