These servers do not represent the minimum hardware required for loading any terminology. The LexEVS Local Runtime performs adequately in an environment with a memory limit of 2GB, but users cannot load larger owl files, such as the full NCI Thesaurus or NCI Metathesaurus, in such environments. Users will have to load such terminologies on more powerful hardware. There does not exists a list showing the minimum hardware for a given terminology. Please refer to the Vocabulary Knowledge Center Support Statement for more information.

The servers listed in the following table represent hardware that LexEVS has been tested on.
