Learning to create a UUID pool

UUID is a 128-bit number assigned to every compute node on a network to identify the compute node globally. UUID is denoted as 32 hexadecimal numbers. In the Cisco UCSM, a server UUID can be generated using the UUID suffix pool. The UCSM software generates a unique prefix to ensure that the generated compute node UUID is unique.

Operating systems including hypervisors and some applications may leverage UUID number binding. The UUIDs generated with a resource pool are portable. In case of a catastrophic failure of the compute node, the pooled UUID assigned through a service profile can be easily transferred to a replacement compute node without going through complex firmware upgrades.
