Drag the identifies on the left to the identity pools in which they belong on the right. Use all identifiers. Each identifier can be used only once.
Explanation:
Identity pools are logical resource pools that can be read and consumed by a service profile or a service profile template. These pools are used to uniquely identify groups of servers that share the same characteristics. A service profile can be used from Cisco Unified Computing System (UCS) Manager to automatically apply configurations to the servers identified by the pool. For Cisco UCS configurations or scenarios that require virtualized identities, the use of identity pools can greatly speed the server creation and template updating processes. There are six types of identity pools that can serve Cisco UCS service profile templates:
– Internet Protocol (IP) pools
– Media Access Control (MAC) pools
– Universally unique identifier (UUID) pools
– World Wide Node Name (WWNN) pools
– World Wide Port Name (WWPN) pools
– World Wide Node/Port Name (WWXN) pools
IP identity pools contain IP addresses, which are 32-bit decimal addresses that are assigned to interfaces. In a Cisco UCS domain, IP pools are typically used to assign one or more management IP addresses to each server’s Cisco Integrated Management Controller (IMC).
MAC identity pools contain MAC addresses, which are 48-bit hexadecimal addresses that are typically burned into a network interface card (NIC). The first 24 bits of a MAC address represent the Organizationally Unique Identifier (OUI), which is a value that is assigned by the Institute of Electrical and Electronics Engineers (IEEE). The OUI identifies the NIC’s manufacturer. The last 24 bits of a MAC address uniquely identify a specific NIC constructed by the manufacturer. This value is almost always an identifier that the manufacturer has never before used in combination with the OUI.
UUID identity pools contain Open Software Foundation 128-bit addresses. These addresses, known as UUIDs, contain a prefix and a suffix. The prefix identifies the unique UCS domain. The suffix is assigned sequentially and can represent the domain ID and host ID. UUIDs are typically used to assign software licenses to a given device.
The WWNN identity pool is a single pool for an entire Cisco UCS domain. WWNNs are 64-bit globally unique identifiers that specify a given Fibre Channel (FC) node. These identifiers are typically used in storage area network (SAN) routing.
Similar to the WWNN identity pool, the WWPN identity pool contains globally unique 64-bit identifiers. However, WWPNs represent a specific FC port, not an entire node.
WWSN identity pools contain a mix of WWNNs and WWPNs. WWxN pools can be used in any place in Cisco UCS Manager that can use WWNN pools and WWPN pools.
