Configuration Limits

The following tables list the Cisco verified limits for Cisco UCS 6200, 6332, and 6324 series fabric interconnects with Cisco UCS Manager Release 3.2.

The limits in this document indicate the maximum scale capability tested for the corresponding feature individually. This number is the absolute maximum currently supported by Cisco UCS Manager for the corresponding feature. When used in combination, the practical limit for each feature may be lower than the maximum limit cited in this document.

Note
