Note: If you are migrating from AGRIS Versions 9.4.6 or earlier, please contact Greenstone Technical Support. 1.3 Upgrading From Earlier Versions of AGRIS Support and technical installation documentation for the AGRIS 18.1.0 release is located at the Technical Info page. Version 18.1.0 Distribution Build 80, Application Build 86 The RAID controller matters, too ‐‐ some of the fastest performance numbers we have seen are coming from the Dell PERC H710 controllers.AGRIS Agribusiness Management System – AGRIS 18.1.0 RAID 5 is acceptable – RAID10 is substantially better (though more costly), and RAID0 should NEVER be used. RAID6 should be avoided for database systems due to the slow disk write speeds.

A database will perform best if there are NO disk I/O operations needed to satisfy user requests, which means sizing the memory based on the expected size of your database, plus memory for the OS.
See "Number of Cores" below to see why more cores may help. Sometime you can get a higher clock speed CPU with lesser number of cores. On the other hand, you should also balance CPU speed against number of cores and the level 1 or 2 cache for the CPU.
For best results, look at 2.2GHz or faster. As such, the faster the clock speed you can get, the better. CPU Clock Speed: A single user running a database on a server only needs one core, but needs a fast clock speed to get fast performance.So, let’s start with the key factors to consider when buying a database server:
