thepolicy to raise an alarm if the CPU temperature exceeds a certain value, or if a server is overutilized or
underutilized.
Thesethreshold policies do not control the hardware or device-level thresholds enforced by endpoints, such
asthe CIMC. Those thresholds are burned in to the hardware components at manufacture.
CiscoUCS enablesyou toconfigure statisticsthreshold policies forthe followingcomponents:
• Servers and server components
• Uplink Ethernet ports
• Ethernet server ports, chassis, and fabric interconnects
• Fibre Channel port
Youcannot create or delete a statistics threshold policy for Ethernet server ports, uplink Ethernet ports,
oruplink Fibre Channel ports. Youcan only configure the existing default policy.
Note
Pools
Poolsare collections of identities, or physical or logical resources, that are available in the system. All pools
increasethe flexibility of service profiles and allow you to centrally manage your system resources.
Youcan use pools to segment unconfigured servers or available ranges of server identity information into
groupingsthat make sense for the data center. For example, if you create a pool of unconfigured servers with
similarcharacteristics and include that pool in a service profile, you can use a policy to associate that service
profilewith anavailable, unconfigured server.
Ifyou pool identifying information,such as MAC addresses, you can pre-assign ranges for servers that will
hostspecific applications. For example, all database servers could be configured within the same range of
MACaddresses, UUIDs, and WWNs.

Server Pools

Aserver pool containsa set of servers. These servers typicallyshare the samecharacteristics. Those
characteristicscan be their location in the chassis, or an attribute such as server type, amount of memory,
localstorage, type of CPU, or local drive configuration. Youcan manually assign a server to a server pool,
oruse server pool policies and server pool policy qualifications to automate the assignment.
Ifyour system implements multi-tenancy through organizations, you can designate one or more server pools
tobe used by a specific organization. For example, a pool that includes all servers with two CPUs could be
assignedto the Marketing organization, while all servers with 64 GB memory could be assigned to the Finance
organization.
Aserver pool can include servers from any chassis in the system. A given server can belong to multiple server
pools.

MAC Pools

AMAC pool is a collectionof network identities, or MAC addresses, that are unique in their layer 2
environmentand are available to be assigned to vNICs on a server. If you use MAC pools in service profiles,
