Cisco Bug: CSCuo97907 - Core Multi Processing Policy not limiting core use with certain CPUs
Jul 06, 2020
- Cisco Unified Computing System
Known Affected Releases
2.1(3b)A 2.1(3b)B 2.2(2c)A
Symptom: Blades using a Core Multi Processing policy do not seem to actually honor the policy, but it does show up when booting into BIOS. For example, implementing a policy of one should only show two cores in use. However, in testing with blades using certain CPUs, running ESXi 5.5, running esxtop shows more cores in use. Conditions: Blades (tested on B200 M3) with E5-2643 and E5-2609 CPUs don't appear to honor the changes of a BIOS policy that utilizes the Core Multi Processing option. This defect can Also affect B200 M4 with E5-2683 v3. Other processors may be affected besides what is listed here.
