Cisco UCS Servers

Server Management

With global policies, global server pools and firmware management in Cisco UCS Central, you can manage general and complex server deployments for the following servers in your registered UCS domains:

  • Cisco UCS B-Series Blade Servers

  • Cisco UCS C-Series Rack-Mount Servers

  • Cisco UCS Mini

Equipment Policies

Equipment policies allow you to tune your servers and other equipment to suit your requirements. Equipment policies can only be set at the domain group level, and apply to all servers in that domain group.


Note

Equipment policies are not included in service profiles.

Configuring the Chassis/FEX Discovery Policy

Procedure

  Command or Action Purpose
Step 1

UCSC# connect policy-mgr

Enters policy manager mode.

Step 2

UCSC(policy-mgr) # scope domain-group domain-group

Enters domain group root mode and (optionally) enters a sub-domain group under the domain group root. To enter the domain group root mode, type / as the domain-group .

Step 3

UCSC(policy-mgr) /domain-group # scope chassis-disc-policy

Enters organization chassis/FEX discovery policy mode.

Step 4

UCSC(policy-mgr) /domain-group/chassis-disc-policy # set action {1-link | 2-link | 4-link | 8-link | platform-max}

Specifies the minimum threshold for the number of links between the chassis or FEX and the fabric interconnect.

Step 5

UCSC(policy-mgr) /domain-group/chassis-disc-policy # set link-aggregation-pref {none | port-channel}

Specifies whether the links from the IOMs or FEXes to the fabric interconnects are grouped in a port channel.

Note 

The link grouping preference only takes effect if both sides of the links between an IOM or FEX and the fabric interconnect support fabric port channels. If one side of the links does not support fabric port channels, this preference is ignored and the links are not grouped in a port channel.

Step 6

UCSC(policy-mgr) /domain-group/chassis-disc-policy # commit-buffer

Commits the transaction to the system configuration.

Example

The following example shows how to:

  • Configure the chassis discovery policy to discovery chassis with four links to a fabric interconnect

UCSC# connect policy-mgr
UCSC(policy-mgr)# scope domain-group / 
UCSC(policy-mgr) /domain-group # scope chassis-disc-policy
UCSC(policy-mgr) /domain-group/chassis-disc-policy # set action 4-link

Power Control Policy

Cisco UCS uses the priority set in the power control policy along with the blade type and configuration to calculate the initial power allocation for each blade within a chassis. During normal operation, the active blades within a chassis can borrow power from idle blades within the same chassis. If all blades are active and reach the power cap, service profiles with higher priority power control policies take precedence over service profiles with lower priority power control policies.

Priority is ranked on a scale of 1-10, where 1 indicates the highest priority and 10 indicates lowest priority. The default priority is 5.

For mission-critical application a special priority called no-cap is also available. Setting the priority to no-cap prevents Cisco UCS from leveraging unused power from a particular server. With this setting, the server is allocated the maximum amount of power possible for that type of server.


Note

You must include the power control policy in a service profile and that service profile must be associated with a server for it to take effect.

Inventory Management

Cisco UCS Central collects the inventory details from all registered Cisco UCS domains. You can view and monitor the components in the registered Cisco UCS domains from the domain management panel.

When a Cisco UCS domain is successfully registered, Cisco UCS Central starts collecting the following details:

  • Physical Inventory

  • Service profiles and service profile templates

  • Fault information

Physical Inventory

The physical inventory details of the components in Cisco UCS domains are organized under domains. The Cisco UCS domains that do not belong to any domain groups are placed under ungrouped domains. You can view detailed equipment status, and the following physical details of components in the domain management panel:

  • Fabric interconnects - switch card modules

  • Servers - blades/rack mount servers

  • Chassis - io modules

  • Fabric extenders

Service Profiles and Templates

You can view a complete list of service profiles and service profile templates available in the registered Cisco UCS domains from the Servers tab. The Service Profile panel displays a aggregated list of the service profiles. Service profiles with the same name are grouped under the organizations they are assigned to. Instance count next to the service profile name will provide the number of times that particular service profile is used in Cisco UCS domains.

From the Service Profile Template panel, you can view the available service profile templates, organization and the number of times each service profile template is used in the Cisco UCS Domain.
