Content Addressable Memory for ExaScale | 287
There is a default CAM profile and microcode that is preprogrammed in the system.You can configure
additional CAM profiles using the templates described in this chapter, as well as define your own
CAM-profiles. The provided templates have been qualified by Dell Force10 Networks. FTOS also
supports creating individual CAM-profiles, but Dell Force10 does not certify that these templates will
function as expected. Applying different CAM profile templates changes the amount of space availability
in each region.
Table 14-1, "CAM-profile Templates," in Content Addressable Memory for ExaScale lists and describes
the recommended CAM-profile templates. In general, non-default profiles allocate more space to
particular regions to accommodate specific applications. The size of the partitions is measured in entries.
The total CAM space is finite, therefor adding entries to one region necessarily decreases the number
available to other regions.
