Hardware evaluation of ArcGIS 9.2 Server Installation Machine

ArcGIS Server does not have an absolute hardware metric, but according to experience If the peak value of ArcGIS Server is 18 concurrent connections , The CPU must have at least 45 or more specrate values to meet the requirements. In this case, the server can return a data display request within 8 seconds. . When the specrate is 45, it is equivalent to an Intel Xeon dual-CPU (CORE) 3.8ghz server.

Our server is dual-cpu2.7ghz, so at this time, only 10 peak users can be connected and the graphic display is returned within 8 seconds.. If the maximum number of concurrent connections is 30, we recommend that you configure the specrate value.80 or more servers, such as Intel 4 CPU (CORE) GHz servers. In addition, when you configure the ArcGIS product, the memory configuration generally follows a CPU Configuration2 GB memory,2 GB memory for a CPU refers to a core.(One in dual-core ). Appendix:

There are several different ways to measure computer performance. one way is to measure how fast the computer completes a single task; this is a speed measure. another way is to measure how many tasks a computer can accomplish in a certain amount of time; this is called a throughput, capacity or rate measure.

• The spec speed metrics (e.g., specint2000) are used for comparing the ability of a computer to complete single tasks.
• The spec rate metrics (e.g., specint_rate2000) Measure the throughput or rate of a machine carrying out a number of tasks.

For the rate metrics, multiple copies of the benchmarks are run simultaneously. typically, the number of copies is the same as the number of CPUs on the machine, but this is not a requirement. for example, it wocould be perfectly acceptable to run 63 copies of the benchmarks on a 64-cpu machine (thereby leaving one CPU free to handle system overhead The GIS system design strategies released by ESRI are also described in detail.
